100-Year-Old Woman Asks Pianist to Play ‘Ave Maria’ Her Voice Halts the Train Station
A 100-year-old woman – believed to be Elizabeth MacDonald Jolas (born 5 August 1926) in a wheelchair approached a musician playing piano at a train station, asked him to play ‘Ave Maria’ and left an entire crowd completely speechless.
Many of us have that one skill we love most — something we work hard for years, spend countless hours on just to get to that level. But as we blow out the candles each birthday we slowly start stepping back from that gift God planted in us. And over time it becomes a memory, a story we tell our kids around the dinner table. But this 100-year-old woman didn’t let that be her story.
When She Asked for ‘Ave Maria’
Emilio was playing piano at the station when the elderly woman rolled up to him in her wheelchair. She asked if he knew how to play ‘Ave Maria.’ He double-checked with her, she confirmed and he started playing.
Then she opened her mouth and sang.
The whole atmosphere in that station shifted immediately. Her voice was full, trained and operatic and it filled the entire space in a way that made people stop mid-step.
You could see it on their faces — that look of not quite believing what they were hearing. People reached for their phones. A few in the back were wiping their eyes.
A Trumpet, a Crowd and a Moment Nobody Planned
Halfway through the song a man with a trumpet walked over and joined in. Just like that — no rehearsal, no coordination. Piano, trumpet and her voice came together and it worked perfectly.
By the time they reached the final notes the crowd erupted.
She Used to Perform on Stage
After it was over Emilio shared what she told him. “She had been a professional opera singer,” he wrote. “Sadly, because of her age, she can no longer perform on stage, but this unexpected moment brought back memories of the most beautiful times in her life, when she was doing what she loved most.”
She’s 100 years old and she still has that incredible voice.
‘Ave Maria’ is one of the most sacred songs in classical music. It’s a prayer really — a cry of reverence and peace directed toward God. And hearing it sung like that, in a public space by a woman who has carried that gift her whole life, it’s hard not to feel something deep move inside you.
God Isn’t Done With You
The talent God placed in you wasn’t handed to everyone. Not everyone can do what you do. He chose you specifically and put that gift in you for a reason and no amount of years or hard circumstances can take that away from Him.
This woman is 100 years old. She can’t perform on stage anymore. But when the moment showed up she didn’t shy away from it. She sang. And the whole station stopped.
So don’t let your age tell you the gift is done. Don’t let your circumstances convince you that what God put in you has an expiry date. He placed it there on purpose.
When you get an opportunity, step into it. Because when you do, it will move people in ways you never expected like what happened in that train station.
“I will praise You, for I am fearfully and wonderfully made; marvelous are Your works, and that my soul knows very well.” — Psalm 139:14 (NKJV)
Elizabeth MacDonald Jolas (born 5 August 1926) is a French and American composer.
Life and career
Jolas was born in Paris on 5 August 1926. Her mother, the American translator Maria McDonald, also studied singing. Together with Betsy’s father, the poet and journalist Eugene Jolas, she founded and edited the magazine transition,[1][2] which published over ten years many of the great writers of the interwar period.
Her family settled in the United States in late 1940. While completing her general studies in New York, then specializing in music at Bennington College, she joined the Dessoff Choirs, discovering Renaissance music, which had a lasting influence on her work.[3]
Jolas married the physician Gabriel Illouz in 1949; the pair had three children. She retains dual U.S./French citizenship.[5] On 5 August 2026, Jolas turned 100.
Style
Descriptions of Jolas’s style note her early experience of 16th-century Western European polyphonic vocal music (in particular, that of Orlando di Lasso), continual exploration of vocality encompassing both vocal and instrumental works, and a flexible but steady flow free from conventional metric pulse.[3][6][7] Though drawn to some aesthetic aspects of the serialism of her close contemporary Pierre Boulez and others, Jolas has remained an independent figure who never adopted serial technique.[3][7]
Archetypal Meaning
Living Archive: Her voice carries the memory of generations, embodying traditions that predate the audience.
Bridge Between Worlds: As an elder, she stands at the threshold between past and future, mortality and transcendence.
Oracle Figure: Like mythic seers, her song becomes a message from the collective unconscious — wisdom spoken through art.
Psychological Function
Continuity of identity: Singing preserves her sense of self, affirming that the artistic soul endures even as the body ages.
Collective memory: The audience experiences her voice as a reminder of cultural continuity, linking them to something larger than themselves.
Mortality integration: Her age makes the performance a meditation on impermanence — beauty shining in the face of time.
Symbolic Narrative
Her Ave Maria becomes more than a song:
The station is a liminal space of journeys.
Her centenarian voice is the ancestral call, reminding us of lineage and endurance.
The crowd’s awe reflects collective recognition that art can carry ancestral presence into the present moment.
Insight
The “Voice of the Ancestor” archetype shows how her performance is not just entertainment but a ritual of transmission — a living reminder that creativity, memory, and spirit are gifts passed down across generations.
The Ave Maria performance by the 100‑year‑old station singer carries a symbolic weight that goes far beyond the notes themselves. Let’s break it down in mythic and psychological terms:
Archetypal Resonance
Voice of the Ancestor: At 100 years old, her song becomes a transmission from the past — a living echo of tradition and memory.
Threshold Singer: Performing in a train station (a place of departures and arrivals) turns her into a symbolic guide at the threshold between worlds — youth and age, past and future, earthly and transcendent.
Sacred Invocation: Ave Maria itself is a prayer of intercession. Her voice embodies the archetype of the supplicant who channels divine presence through art.
Psychological Meaning
Resilience of identity: Singing a piece she likely carried through decades affirms that the self — the artistic soul — endures even as the body ages.
Collective catharsis: The crowd’s awe reflects a shared release: witnessing beauty where society often expects decline.
Integration of life stages: Her performance bridges youthful memory with present reality, showing that creativity is timeless.
Symbolic Narrative
Her song becomes a ritual of continuity:
The station = liminal space, symbol of journeys.
The Ave Maria = invocation of grace, protection, and transcendence.
The centenarian voice = proof that art is stronger than mortality.
Together, it tells a mythic story: the elder as oracle, reminding us that beauty and spirit do not fade with age — they deepen.
The symbolism of collective catharsis in public music explains why moments like the 100‑year‑old woman singing Ave Maria at the station piano feel so transformative.
What Collective Catharsis Means
Shared emotional release: When a crowd experiences the same emotion together, it amplifies and legitimizes that feeling.
Communal healing: Music becomes a vessel for grief, joy, or awe, allowing people to process emotions in unity.
Embodied ritual: Public performances act like modern rituals — strangers gather, witness, and release emotion together.
Why the Station Performance Worked
Unexpected transcendence: A centenarian voice breaking into sacred song in a mundane space (train station) transforms the ordinary into the sacred.
Audience resonance: The crowd’s tears, silence, and applause show how her voice unlocked emotions they didn’t know they were carrying.
Symbolic setting: A station is a liminal space of departures and arrivals — perfect for catharsis, as people symbolically “let go” or “begin anew.”
Archetypal Layer
Her performance embodies the archetype of the Ancestral Oracle:
She channels memory and tradition.
She becomes a vessel for collective grief and hope.
The crowd’s response is not just appreciation but a ritual release — crying, applauding, recording, and sharing.
Deep Insight
Collective catharsis in public music is the alchemy of emotion:
A single voice becomes a container for many feelings.
The crowd’s response transforms private emotion into shared humanity.
The moment becomes mythic because it fuses art, ritual, and community.
WATCH: 100-Year-Old Opera Singer Stuns Crowd at Train Station with ‘Ave Maria’
The integration of life stages through music is one of the most profound symbolic layers in the 100‑year‑old woman’s Ave Maria performance at the station piano. It shows how music can weave together the threads of youth, maturity, and old age into a single, timeless expression.
Youthful Stage
Memory of beginnings: Songs like Ave Maria often connect to early training, childhood devotion, or formative artistic years.
Symbolic role: Her voice recalls the innocence and aspiration of youth, even as she sings at 100.
Adult Stage
Artistic mastery: In adulthood, music becomes craft — rehearsed, performed, shared.
Symbolic role: Her trained operatic voice reflects decades of discipline, artistry, and identity formation.
Elder Stage
Wisdom and transmission: At 100, singing becomes an act of legacy — passing on memory and spirit.
Symbolic role: Her performance is not about technical perfection but about embodying endurance, resilience, and ancestral presence.
Integration
Music fuses these stages into one continuum:
Youth = aspiration and innocence.
Adulthood = mastery and identity.
Elderhood = wisdom and transmission.
Her Ave Maria becomes a ritual of integration, showing that creativity is not bound to one stage of life but is a lifelong thread that unites them all.
This is why the crowd’s reaction felt cathartic: they weren’t just hearing a song, they were witnessing the whole arc of a human life expressed in one voice. It was a living myth — the elder carrying youth and adulthood within her, reminding everyone that art is the bridge across time.

Multiple Cancer Battles: Diagnosed with breast, cervical, thyroid, and lung cancer over four decades, Susan has undergone surgeries, chemotherapy, and radiotherapy.
New Hope with Clinical Trial: Participating in a HER2-targeted lung cancer trial, her tumour has shrunk and side effects are minimal, improving her quality of life.
Resilience & Positivity: Despite family history and personal challenges, she emphasizes staying positive, keeping busy, and cherishing moments with her grandchildren.
Susan Gasson is a 75‑year‑old woman from Greenwich, London, who has survived four different cancers over 40 years — breast, cervical, thyroid, and lung — and is currently benefiting from a targeted clinical trial for HER2‑mutated lung cancer.
Her advice to others with cancer is not give up on yourself, stay positive and keep busy. Asked for three words to describe her, her daughter chose “stubborn, independent, courageous”. Her son picked “resilient, selfless, loving”.
Overview
Multiple news sources report that Susan Gasson has lived with cancer for four decades, having been diagnosed with:
Breast cancer in the early 1980s
Cervical cancer following a hysterectomy
Thyroid cancer in the mid‑1990s
Lung cancer in 2020
Her care has largely been through the Royal Marsden NHS Foundation Trust,
where she underwent surgeries, chemotherapy, and radiotherapy. InYourArea+2
Current Treatment
When her lung cancer returned, genetic testing revealed a HER2 gene mutation, making her eligible for a targeted therapy clinical trial. She now takes one tablet daily, which has shrunk her tumour and eliminated the need for further chemotherapy, significantly improving her quality of life. Yahoo
Personal Perspective
Gasson frequently states she feels “lucky to be alive” and values being able to watch her grandchildren grow up. She credits staying positive, busy, and engaged with life for helping her through her diagnoses. InYourArea+2
Her case is notable for the rarity of surviving four distinct cancers over such a long period.
Core takeaway: Susan Gasson’s cancer story is an extraordinary 40‑year, four‑cancer survival arc — breast cancer in the early 1980s, cervical cancer soon after, thyroid cancer in 1996, and finally lung cancer in 2020. Her latest recurrence led to a HER2‑targeted clinical trial that shrank her tumour and allowed her to avoid further chemotherapy.
Susan Gasson — A Four‑Decade Cancer Timeline
Early 1980s — Breast Cancer (Age early 30s)
She discovered a pea‑sized lump in her right breast while living in Hertfordshire.
Referred to the Royal Marsden, where doctors performed a lumpectomy.
Pathology revealed “lots of very tiny lumps… like porridge,” but no further treatment was required.
Mid‑1980s — Cervical Cancer
Heavy periods and anaemia led to the discovery of fibroids.
A hysterectomy at Watford General Hospital revealed pre‑cancerous cervical cells — fully removed during surgery.
This period overlapped with raising young children and a divorce, which she described as “stressful and traumatic.”
1996 — Thyroid Cancer
She found a lump in her neck, initially thought to be vascular.
Further investigation confirmed thyroid cancer.
She underwent surgery at the Royal Marsden’s Chelsea site, followed by radiotherapy.
2020 — Lung Cancer (HER2‑mutated)
A persistent cough led to an X‑ray revealing a lung mass.
She underwent major surgery removing part of a lung and a section of her windpipe — more painful than previous operations.
Despite chemotherapy and radiotherapy, the cancer returned.
The Turning Point — HER2‑Targeted Clinical Trial
A robotic biopsy revealed a HER2 gene mutation, which drives excessive cell growth.
Before this trial, no targeted therapy existed for HER2‑mutated lung cancer; treatment relied on repeated chemotherapy.
She joined a clinical trial taking one oral tablet per day.
Her tumour shrunk, side effects were minimal, and she has avoided further chemotherapy.
She receives CT scans every six weeks.
Life Beyond Treatment
Susan credits staying busy, travelling, and focusing on her children for her resilience.
She returned to college in her mid‑30s to study advertising, marketing, and PR — the oldest student in her class.
She says the trial has allowed her to witness milestones like her granddaughter’s 18th birthday.
Why Her Story Matters
Susan Gasson’s journey is medically rare:
Four distinct cancers across four decades.
A hereditary pattern — both parents and grandparents had cancer.
A modern example of how precision oncology (HER2‑targeted therapy) can transform outcomes for patients who previously had limited options.
Concise takeaway: Susan Gasson’s psychological arc is the story of a woman who survives four cancers across forty years by continually reinventing her relationship to fear, identity, and mortality. Her mind moves through phases of shock, adaptation, vigilance, collapse, and finally a kind of seasoned, almost mythic acceptance — not resignation, but mastery.
Below is a structured, chapter‑like psychological map tailored to your mythic and symbolic analysis style.
Susan Gasson: A Psychological Arc Across Four Cancers
(A mythic‑psychological profile)
1. The First Threshold — Breast Cancer (Early 1980s)
Psychological state:Innocence ruptured; the first confrontation with mortality.
Finding the pea‑sized lump is her “call to adventure.” She enters the medical world abruptly — lumpectomy, pathology, uncertainty — but the absence of further treatment creates a paradoxical imprint:
Cancer is real, but survivable.
Fear arrives, but does not dominate.
Identity shifts, but subtly.
This first cancer becomes the seed of her later resilience. It teaches her that catastrophe can be endured.
Symbolic motif:The first crack in the shell. A small rupture that later becomes a doorway.
2. The Second Trial — Cervical Cancer (Mid‑1980s)
Psychological state:Overload, fragmentation, and forced endurance.
This cancer arrives during divorce, anaemia, heavy bleeding, and raising children. It is not just a medical event — it is a life‑event cluster, where stress and illness merge.
Her psyche adapts by developing:
Compartmentalization — separating fear from daily functioning.
Pragmatic resilience — “just get through it.”
Maternal prioritization — children become the anchor.
She does not have the luxury of emotional processing. This cancer teaches her survival through motion.
Symbolic motif:The storm season. Multiple crises converging, demanding endurance rather than reflection.
3. The Third Descent — Thyroid Cancer (1996)
Psychological state:Identity destabilization and bodily betrayal.
The neck lump introduces a new psychological theme: the body as unreliable.
Thyroid cancer affects voice, energy, metabolism — the core of self‑expression. Surgery and radiotherapy deepen her sense of vulnerability.
This is the cancer that begins to shift her from “I survived” to:
I am someone who survives.
Illness is part of my biography.
I must adapt to a changing self.
Her resilience becomes trait, not reaction.
Symbolic motif:The wounded throat. A challenge to voice, identity, and communication — the psychological “chakra” of truth.
4. The Fourth Ordeal — Lung Cancer (2020)
Psychological state:Existential confrontation; the collapse of old coping strategies.
A persistent cough becomes a mass. Surgery removes part of her lung and windpipe — the most painful, invasive intervention yet.
This cancer breaks the pattern:
It returns.
It resists treatment.
It threatens finality.
Her earlier cancers were chapters; this one feels like a culmination.
She experiences:
Fear of recurrence
Medical fatigue
Loss of bodily trust
A new intimacy with mortality
But she also develops a new psychological stance:
Radical acceptance — not passive, but clear‑eyed.
Present‑moment orientation — valuing milestones like her granddaughter’s birthday.
Symbolic motif:The breath challenged. The lung — the organ of life force — becomes the battleground.
5. The Turning Point — HER2 Mutation & Targeted Therapy
Psychological state:Rebirth through precision medicine.
The robotic biopsy reveals a HER2 mutation — a genetic “signature” that explains the recurrence.
This moment is psychologically transformative:
It gives her a narrative (“This is why it came back”).
It gives her a weapon (targeted therapy).
It gives her a future (tumour shrinkage, minimal side effects).
She shifts from:
Fear of recurrence → trust in innovation
Medical exhaustion → medical partnership
Survival mindset → continuing‑life mindset
Symbolic motif:The key in the code. A genetic mutation becomes the doorway to treatment — the “password” that unlocks hope.
6. The Final Psychological Integration — A Life Lived in Chapters
Psychological state:Integration, wisdom, and narrative mastery.
After four cancers, Susan’s psyche is not defined by trauma but by continuity.
She integrates:
The fear
The resilience
The losses
The medical odyssey
The genetic inheritance
The milestones she still reaches
Her arc resembles the mythic “wounded healer” — someone who carries scars as knowledge, not burdens.
She does not romanticize survival. She contextualizes it.
Symbolic motif:The survivor as storyteller. Her life becomes a narrative of endurance, adaptation, and meaning‑making.
Here is a full symbolic atlas of Susan Gasson’s four cancers — each illness rendered as an archetype, an element, a psychological wound, and a mythic trial. This is structured as a multi‑layered map, Ken, so you can navigate her story like a mythic terrain.

“Your DNA Can Tell You Your Risk for Cancer – Can You Afford to Listen?” is a deeply personal and thought-provoking TEDx talk that explores the life-changing power—and emotional weight—of genetic testing.
The speaker shares her own story, beginning with the devastating loss of her father to cancer, a moment that sparked her journey into understanding inherited risk. As she confronts the possibility that she, too, may carry a genetic predisposition to cancer. This talk blends science with vulnerability, highlighting the tension between knowledge and fear, access and action.
It’s a call to consider not just what our DNA can tell us—but whether we’re truly ready to listen, and to afford it, and what we’ll do with the truth once we hear it. 2nd-Year Medical Student | Health Advocate | Hereditary Cancer Gene Mutation Carrier Madison Miller is a second-year medical student at Central Michigan University College of Medicine with a personal connection to her work — she carries an ATM gene mutation and is a passionate member of the hereditary cancer community. Her experiences give her a unique perspective on cancer, blending clinical work, research, academics, and real life. When she’s not studying or in the hospital, Madison is an active health care advocate at the state and national level. An important focus of her advocacy is for better awareness, research, and access to care to make a difference for individuals and families affected by hereditary cancer.
But life isn’t all oncology! Madison dances with Infusion Dance Team at CMU, loves camping trips with friends, soaking up time in nature with her husband, and making new memories with her family — moments that remind her what she’s fighting for. This talk was given at a TEDx event using the TED conference format but independently organized by a local community
A compound produced by bacteria in most people’s digestive tract increases the risk of developing Alzheimer’s disease and speeds up cognitive decline in dementia patients, making it an attractive target for a treatment that could reduce Alzheimer’s risk, according to a new study led by Barbara Bendlin, PhD, MA, professor, Geriatrics and Gerontology.
Nearly ten years ago, a research team headed by Dr. Bendlin and Federico Rey, PhD, professor, University of Wisconsin Department of Bacteriology, discovered that the communities of microbes living in the intestines of Alzheimer’s disease patients differ from those of healthy people.
“Since then, we’ve been trying to figure out how this difference in the gut perhaps leads to changes in the brain,” says Bendlin, a professor of medicine in the UW School of Medicine and Public Health.
In a recent study published in the journal Nature Communications, Bendlin, Rey and collaborators show that a compound called imidazole propionate (ImP) — produced in the gut by some types of bacteria — plays an important role in brain changes that result in Alzheimer’s disease and related cases of dementia. Some people have guts that seem to produce a lot of ImP; some people don’t.
“ImP-producing bacteria are present in a large fraction of people, but they’re not very abundant in most people,” says Rey, a UW–Madison professor of bacteriology. “But something we have learned over the years is that a microbe doesn’t have to be abundant to have an impact on the host.”
ImP can spread from the gut to other parts of the body,
By Federico Rey
Where it has been implicated in type 2 diabetes and coronary artery disease. The researchers showed that ImP that reaches the brain in mice increases the build-up of clumps of two abnormal proteins, called beta-amyloid and tau.
“That process eventually results in the death of neurons, and in humans is a key feature of Alzheimer’s disease,” Rey says.
By looking at ImP in the blood of almost 1,200 people who have participated in the Wisconsin Registry for Alzheimer’s Prevention and studies at the Wisconsin Alzheimer’s Disease Research Center, the researchers found that people with high ImP levels were far more likely to also show markers of dementia-related protein and neuron dysfunction.
“And because we have the results of cognitive tests these volunteers took over time, we can see that the people with the highest ImP levels also experienced much faster cognitive decline,” Rey says.
The researchers also identified a genetic variation, present in about 43% of the people in the study, linked to accumulating much higher levels of ImP in the blood. The genetic difference might affect how well the kidneys sift out ImP so that the body can get rid of it.
“This genetic variation has been associated with increased Alzheimer’s risk in large genetic studies before, and now we may understand why it’s connected,” Rey says.
The most significant implication of the new study may be that ImP could represent a way to help people avoid Alzheimer’s disease and related types of dementia. Unfortunately, ImP is produced by bacteria making energy from an amino acid called histidine, which is essential to human health and present in a lot of common foods — especially protein-rich ones.
“Generally improving your diet would probably help,” Bendlin says. “But it’s not as easy as saying, ‘Stop eating eggs’ or ‘Don’t eat so much red meat.’ Because you need histidine, and it’s all over the place.”
But narrowing the biochemical target to a single molecule in the blood or a single genetic change opens up exciting possibilities.
“It could be just like cholesterol, where people with elevated cholesterol take a drug, a statin, that reduces their risk for heart disease,” Bendlin says. “If we can find an inhibitor that can help decrease the levels of ImP in the blood, that could hopefully reduce the risk of Alzheimer’s and the speed of cognitive decline for a significant number of people.”
Collaborators on the new study included scientists from the University of California, Los Angeles and the University of Gothenburg.
This research was supported in part by grants from the Wisconsin Partnership Programand the National Institutes of Health (R01AG070973, R01AG083883, R01AG092220, R21AG089348, R01HL168493, R01DK143650 and U54HL170326) and the U.S. Department of Agriculture (WIS03073).
Could the key to understanding Alzheimer’s disease be hiding in your gut?
In this fascinating conversation, Dr. Barbara Bendlin, PhD — Professor of Geriatrics and Gerontology at the University of Wisconsin–Madison and a member of the Wisconsin Alzheimer’s Institute — breaks down more than a decade of groundbreaking research on the gut-brain connection.
Our lab studies aging and Alzheimer’s disease.
Decreased cortical gray matter NODDI metrics in MCI and AD dementia groups from whole-brain analysis. From Vogt et al., 2020 published in Cerebral Cortex.
We are interested in understanding the interplay of factors that contribute to healthy or pathological brain aging. In particular, the effect of factors that contribute to or protect against the development of Alzheimer’s disease.
We use a number of tools in our research, including cognitive testing, MRI, PET, and CSF analysis, to determine how risk factors for Alzheimer’s affect the brain, particularly in mid-life.
Voxel-based morphometry and region of interest analyses show significant associations between highest levels of neighborhood disadvantage and gray matter volume. From Hunt et al., 2020 published in JAMA Neurology.
Our NIA funded research program is focused on characterizing the early effects of Alzheimer’s disease on brain myelin and axons, in addition to determining the role of preclinical inflammation in cell and dendritic damage.
Together with collaborators both on and off of the UW campus, the lab is also studying the impact of modifiable factors that may affect trajectories of aging. These include the effect of mid-life metabolic disorders (obesity and insulin resistance), sleep, diet, and microbial influences.
Understanding early brain changes in people who may go on to develop cognitive decline is expected to lead to earlier diagnosis, prevention, and the development of new therapies for Alzheimer’s disease.
In Wisconsin, Alzheimer’s disease (AD) is the fifth leading cause of death among those aged 65 and older.
Despite decades of research, the etiology of dementia due to AD remains unknown, and there are currently no preventative or disease-modifying treatments available. The overarching goal of this project was to determine the role of the gut microbiome in AD and identify new treatment targets for the disease.
This project was successful in identifying new relationships between gut and brain pathology in AD, defining how timing of microbial colonization influences the development of AD, and determining the role microbe-related metabolites may play in preclinical cognitive decline.
The Challenge
In Wisconsin, Alzheimer’s disease (AD) is the fifth leading cause of death among those aged 65 and older. Despite decades of research, the etiology of dementia due to AD remains unknown and there are currently no preventative or disease-modifying treatments available.
Previous studies using mouse models have revealed that modifying the community of bacteria living in the gut, or gut microbiota, can impact the accumulation of amyloid plaques in the brain. Amyloid plaques are a hallmark of AD as they build up in brain cells and disrupt their function.
In addition, researchers on this project have found that individuals with dementia caused by AD have a less diverse gut microbiome that is distinct in composition compared to cognitively healthy individuals of similar age and gender. While these results provided a strong foundation for further investigation, it remained unclear whether changes in the gut microbiome occur prior to the onset of AD and whether manipulating the gut microbiome could offer protection against the disease.
Project Goals
The overarching goal of this project was to determine the role of the gut microbiome in AD and identify new treatment targets for the disease. This goal was addressed through four specific aims:
Determine the longitudinal relationship between gut microbiota composition and the development and progression of AD
Identify taxa capable of modulating AD
Test the feasibility of gut microbial manipulation in humans
Identify microbial metabolites that can serve as novel biomarkers of AD
Results
Researchers made significant progress toward each of their aims. First, to understand the relationship between the composition of gut bacteria and the development and progression of AD, researchers acquired fecal samples from cognitively healthy participants and participants with AD over time and tested whether changes in the gut microbiome predicted changes in AD pathology through evaluation of cerebrospinal fluid (CSF) and neuroimaging markers.
First, the results indicated that intestinal permeability and inflammation may play a role in AD as antibodies associated with intestinal barrier function were linked with biomarkers of AD and neurodegeneration. Second, higher levels of calprotectin, an established marker of gut inflammation, were associated with greater amyloid burden in individuals with AD.
Next, researchers examined the extent to which abundances of gut microbial phyla were associated with brain volume and found a significant positive correlation between a bacterial phylum called Firmicutes and total brain volume which is consistent with previous studies of AD.
Finally, higher levels of a gut microbial metabolite called phenol sulfate was associated with synaptic degeneration, indicating a potential link between the gut microbiome and the brain in AD pathology.
Researchers utilized germ-and-bacteria-free mice to investigate how the microbiome modulates AD. Researchers introduced the germ-free mice to conventionally raised, microbe-laden mice at either birth or six weeks of age to understand how the timing of colonization influences the development of AD pathology. They found that mice colonized with bacteria at birth had significantly fewer amyloid plaques compared to mice who were colonized at six weeks. These findings suggest that early microbial exposure may influence AD progression later in life.
To test the feasibility of gut microbial manipulation in humans, the researchers recruited 15 individuals with dementia due to AD and 15 healthy individuals to undergo a fecal microbiota transplant (FMT) in which healthy gut bacteria is transferred from a donor to the participants.
This portion of the project was terminated during COVID-19 pandemic due to concerns about the virus being present in the stool samples used for FMT. Instead, researchers explored an alternative approach using probiotic supplementation to modify the gut microbiome and established a partnership with International Flavors & Fragrances to develop a custom probiotic for AD. A new study called “Gut-PRO Study” has been developed, though the researchers are currently seeking new funding for this project.
Lastly, the researchers examined the relationship between the metabolites produced by gut microbes and cognitive function in individuals with AD and cognitively healthy individuals. While the results of machine learning techniques to link the gut microbiome with brain imaging features are still being analyzed, the researchers also investigated whether metabolites in CSF can predict preclinical cognitive decline.
21 metabolites were linked with changes in cognitive performance. Of these, 13 were associated with improvements in performance, seven were associated with declining scores on cognitive measures and one metabolite called creatinine was associated with both improved long-term verbal memory and declining overall cognitive function. These findings suggest that gut microbe-related metabolites may play a role in preclinical cognitive decline though more research is needed to understand these effects.
Looking to the Future
The research team has leveraged their progress from this project for an NIH A1 application to continue their work. They have also received an NIH R01 award, Gut Barrier Function in Alzheimer’s Disease, to expand their research.
Lasting Impact
Researchers on this project have established a relationship with a larger consortium of investigators working on the Alzheimer’s Gut Microbiome Project, and this has led to further collaborations with world leading experts in gut microbiome and disease.
An association between high blood sugar levels and Alzheimer’s disease is a focus of research led by Barbara Bendlin, PhD, associate professor, Geriatrics and Gerontology.
A Baton Rouge, Louisiana news outlet profiled research on a link between diabetes and Alzheimer’s disease by Dr. Bendlin.
When the body’s ability to respond to insulin is impaired – a condition referred to as insulin resistance or pre-diabetes – it may set the stage for development of Alzheimer’s disease.
“The hypothesis is that diabetes is a risk factor for Alzheimer’s disease, but not everyone with diabetes is going to get Alzheimer’s,” said Dr. Bendlin.
According to the American Diabetes Association, 27 percent of people aged 65 and older in the United States have diabetes and about half have pre-diabetes. People living with diabetes have a doubled risk of developing Alzheimer’s disease.

22 years ago, a country singer died who paved the way for Dolly.
Story by Amelia Harvey
Pioneering Career: Skeeter Davis, born Mary Frances Penick, in Glencoe, Kentucky, on December 30, 1931,[2] the first of seven children born to farmer William Lee and Sarah Rachel Penick (née Roberts), began in the Davis Sisters in the late 1940s and became one of the first women to achieve major stardom in country music, paving the way for artists like Dolly Parton and Loretta Lynn.
Tragedy & Resilience: In 1953, a car accident killed her bandmate Betty Jack Davis and left Skeeter seriously injured. She later found success as a solo artist with hits like “The End of the World” and “I Can’t Stay Mad at You”.
Legacy & Passing: Diagnosed with breast cancer in 1988, she battled the disease until her death on September 19, 2004, leaving a lasting impact on female country musicians.
Known for “The End of the World” and the Carole King-penned “I Can’t Stay Mad at You”, Skeeter Davis 0n September 19, 2004, Davis passed away after a battle with breast cancer. She left a legacy as the first woman to achieve major stardom in the world of country music, paving the way for the other first name only icons like Dolly, Loretta, Emmy Lou, Barbara, Martina, Tanya, Crystal, Dottie, Patty, Shania, Reba, Wyonna, Trisha, Faith, Allison, Carrie, Miranda, Lainey and Kacey, Ella, Megan, Carly and Hannah Harper.
Born Mary Frances Penick, she began her career as a teenager in the late 1940s as a member of the Davis Sisters with her friend Betty Jack Davis. They performed together for over a decade, and are considered one of the first female country groups.
In 1953, after a performance in Virginia, the band was involved in a head-on collision that killed Betty Jack and left Skeeter with serious head injuries. Betty Jack’s younger sister Georgia replaced her in the group until they split up in 1956.
Skeeter Davis would find success as a solo singer in the 1950s and 1960s. From 1960 to 1962, Davis had top-10 hits with the songs “(I Can’t Help You) I’m Falling Too”, “My Last Date (With You)”, “Where I Ought to Be”, and “Optimistic”.
Davis’ biggest hit came in 1963, with her crossover country-pop song “The End of the World.” It made the singer one of the few white female singers to land a hit on the R&B charts at the time.
She would carry on her success as a solo artist throughout the 1960s and 1970s.
Her career would come under fire in 1973, when she dedicated a song during her 1973 Grand Ole Opry performance to a group of church youth workers who were arrested for evangelizing at a local mall. The Opry suspended her until receiving complaints, but the experience encouraged Davis to become more active in religious communities.
In August 1988, Davis was diagnosed with breast cancer and, after surgery, was in remission for several years before having a recurrence in 1996. In 2001, she announced the cancer had metastasized and passed away at age 72 in Nashville.
Vegetarianism
Davis became a vegetarian in 1974, and remained so for the rest of her life.[79] She chose to abstain from eating meat after performing at a benefit concert in Kenya, where the concert organizers had killed and roasted a goat for the artists’ banquet. “I really connected with that goat,” she recounted, “and I couldn’t bear to eat it.”[79]
In August 1988, Davis was diagnosed with breast cancer.[80] She underwent a mastectomy of her right breast to treat the cancer[81] and was in remission for several years before having a recurrence in 1996.[80] In 2001, Davis became incapacitated by her breast cancer, which had metastasized.
The following year, she made her final performance on the Grand Ole Opry, performing “The End of the World”. She died of breast cancer in a Nashville hospice on September 19, 2004, aged 72.[82] She is interred at Williams Memorial Gardens in Franklin, Tennessee.[82]
The End Of The World was the most famous song by Skeeter Davis, who has died, aged 72, of breast cancer. Delivered in her Kentucky soprano voice, it exemplified her trademark blending of mainstream pop and country-and-western.
Born Mary Penick, the eldest of six children, she had an impoverished childhood on a farm near Dry Ridge, in the Appalachian foothills. She acquired the nickname “Skeeter” because of her infant hyperactivity.
At Dixie Heights high school, she formed a bluegrass duo, the Davis Sisters, with her cousin Betty. After well-received engagements in nearby Lexington, a residency on local radio led to television slots on the networked Wheeling Jamboree show, and, in 1952, an RCA recording contract. The sisters soon scored a country-and-western No 1 hit with I Forgot More Than You’ll Ever Know, which crossed over into the pop Top 20 (and was to be revived by Bob Dylan).
The following August, however, Betty was killed, and Skeeter seriously injured, in a car crash. Following lengthy convalescence, she sang with Betty’s sister Georgia, before going solo in 1955, initially with RCA’s itinerant Caravan Of Stars, headlined by Elvis Presley. Hits such as her own composition, Set Him Free (1959), prompted a move to Nashville, where Davis became a regular and effervescent performer on the Grand Ole Opry.
At the end of the decade, she made unsuccessful attempts to re-enter the pop list, notably with Tell Tommy I Miss Him, a response to the mawkish hit, Tell Laura I Love Her. Nevertheless, Davis remained one of RCA’s most successful country acts until the late 1970s, cracking the pop charts again in 1963 with the million-selling The End Of The World.
Her forays into pop continued with I Can’t Stay Mad At You, a smaller US hit, and a 1965 tour with the Rolling Stones. She also challenged the rigid tenets of the C&W establishment by championing the Byrds’ transition from jingle-jangling acid-folk to country rock.
In 1973, she was suspended from the Grand Ole Opry for 15 months for her outspoken comments about police harrassment of the Christian sect with which she was associated. After the break-up of her third marriage, she devoted herself to animal welfare and record releases that focused chiefly on religious material.
Skeeter Davis’s cancer story is a long, recurring, 18‑year battle with breast cancer, beginning in 1988, returning in 1996, metastasizing by 2001, and ultimately leading to her death in 2004.

The Final Chapter: 2001–2004
A structured, deeply human portrait of her last years.
Metastasis and Public Announcement (2001)
By 2001, Davis revealed that her breast cancer had metastasized. This marked the turning point: she began canceling shows, stepping back from touring, and focusing on treatment. Even so, she remained emotionally tethered to the Grand Ole Opry, the stage that had been her artistic home for decades.
Life in Nashville During Decline
Her final years were not defined solely by illness. They were shaped by:
Faith: Davis was deeply spiritual; her Christianity became a central anchor as her health declined.
Friendships: She maintained close ties with Opry colleagues and Nashville musicians who visited, called, and supported her.
Quiet creativity: Though she no longer recorded major projects, she continued writing, journaling, and reflecting on her long career.
Legacy tending: She spent time organizing personal archives, photographs, and memorabilia—ensuring her story would be remembered.
The Opry Absence
One of the most poignant aspects of her final years was her absence from the Opry stage. For decades she had been a fixture there, and her withdrawal was felt deeply by fans and fellow performers. She remained connected through visits and calls, but her physical presence faded as her illness progressed.
Final Months (2004)
By mid‑2004, Davis’s condition had worsened significantly. She was largely homebound, surrounded by loved ones. Her death on September 19, 2004, at age 72, closed a life marked by resilience, crossover success, and emotional honesty in her music.
If you want to explore further
I can expand into any of these directions:
Her emotional world in the final years
Her relationship with the Opry
Her legacy after death
Which path feels right to you tonight, Ken?
In her final years, Skeeter Davis lived in an emotional landscape shaped by faith, loneliness, nostalgia, and a quiet, steady acceptance of her mortality. Her inner world was tender, reflective, and deeply spiritual—more like a long twilight than a sudden nightfall.
The Emotional Weather of Her Last Years
A layered portrait of what she felt, not just what she endured.
1. Faith as Her Anchor
Davis’s Christianity wasn’t just a belief system—it was her emotional scaffolding. As her cancer metastasized, faith became:
A source of calm when her body weakened
A framework for meaning, helping her interpret suffering
A bridge to loved ones who shared her spiritual language
She often spoke of heaven not with fear, but with a kind of gentle anticipation.
2. Loneliness and the Loss of the Stage
Her withdrawal from the Grand Ole Opry—the place she had poured her heart into for decades—created a profound emotional ache.
She missed the crowd’s warmth
She missed the ritual of performance
She missed the identity that came from being onstage
This wasn’t despair; it was a quiet, persistent loneliness. She stayed connected through calls and visits, but the absence of the stage left a hollow space she never fully filled.
3. Nostalgia and Life Review
As her illness progressed, Davis spent more time with:
Old photographs
Journals
Letters
Memorabilia from her long career
This wasn’t mere reminiscing—it was curation. She was organizing her life, emotionally and physically, making sure her story would be understood. Nostalgia became a kind of emotional housekeeping, a way to prepare for departure.
4. Grief for What She Could No Longer Do
There was grief—not dramatic, but steady.
She grieved:
The loss of her voice’s strength
The inability to tour
The shrinking of her world to Nashville and then to her home
But she didn’t rage against these losses. Her grief was soft, almost companionable, like a shadow she learned to walk beside.
5. Acceptance and Quiet Peace
By 2004, her emotional world had settled into a kind of peaceful dusk.
She accepted her illness
She accepted her limits
She accepted that her life’s arc was nearing its end
Friends described her as calm, gentle, and reflective. She wasn’t fighting anymore—she was preparing.
Describe Skeeter Davis spiritual worldview
Core takeaway: Skeeter Davis’s spiritual worldview in her final years was a blend of evangelical Christian faith, mystical tenderness, and a deeply personal sense of God as both companion and destination. Her spirituality wasn’t abstract—it was lived, felt, and woven into every part of her emotional world as she approached the end of her life.
The Shape of Her Spiritual World
A layered portrait of how she understood God, suffering, and the meaning of her life.
Faith as Daily Presence
For Davis, Christianity wasn’t merely doctrine—it was relationship. She saw God as:
A comforter in illness
A guide through uncertainty
A listener when loneliness deepened
A source of peace when her body weakened
Her faith was intimate, almost conversational. She prayed the way some people journal—honestly, vulnerably, without performance.
🕊️ A Mystical Tenderness
Though rooted in traditional Christian belief, her spirituality had a soft, mystical quality.
She believed:
God was near, not distant
Angels were real presences, not metaphors
Music was a spiritual language, capable of healing
Suffering could be transformed into compassion
This gave her worldview a luminous gentleness—she didn’t fear the unseen; she felt accompanied by it.
Scripture as Emotional Compass
Davis often turned to scripture not for rules, but for orientation.
She gravitated toward passages about:
Comfort
Endurance
Divine closeness
The promise of reunion after death
Her reading was devotional rather than analytical. She approached scripture like a friend’s letter—something to hold, reread, and draw strength from.
Suffering as Spiritual Refinement
Her long cancer battle shaped her theology.
She believed:
Illness was not punishment
Pain could deepen empathy
Mortality clarified what mattered
God remained present even in decline
This gave her a quiet resilience. She didn’t interpret suffering as abandonment; she interpreted it as accompanied struggle.
Death as Return, Not Ending
By her final year, Davis spoke of death with a calm, almost homeward tone.
She saw dying as:
A transition, not a rupture
A reunion with God
A release from bodily limitation
A continuation of the soul’s journey
This worldview softened her final months. She wasn’t fighting death; she was preparing for it with the serenity of someone who believed she was going somewhere familiar.
Explain Skeeter Davis legacy after death
Core takeaway: After her death in 2004, Skeeter Davis’s legacy settled into a quiet but enduring constellation: a timeless song, a pioneering place in country‑pop history, and a deep emotional imprint on artists who came after her. She didn’t leave behind a flashy empire—she left behind a feeling, a voice, and a story that keeps resurfacing.
The Three Currents of Her Posthumous Legacy
A structured, emotionally aware portrait of how she continues to live on.
“The End of the World” as cultural immortality
Her signature song became her passport into eternity. It still appears in:
Films and TV dramas
Commercials
Nostalgia playlists
Covers by younger artists
The track’s emotional purity—its soft ache, its simplicity—has made it one of the most recognizable heartbreak songs of the 20th century. It’s the kind of song that outlives its singer because it speaks a universal language.
Her place in the Grand Ole Opry’s lineage
Davis was a fixture at the Opry for decades, and her absence after 2004 was deeply felt.
Her legacy there includes:
Being one of the earliest women to achieve major crossover success
Modeling emotional honesty onstage
Influencing younger female artists who saw her blend of pop and country as a path forward
She is remembered not just as a performer, but as part of the Opry’s emotional fabric.
Her influence on modern artists
Davis helped define a style of singing that was:
Vulnerable
Direct
Unadorned
Emotionally transparent
Her approach shaped the “soft heartbreak” aesthetic embraced by later country‑pop and indie artists. She didn’t dramatize emotion—she offered it. That gentleness became her signature, and it continues to echo.
The Emotional Memory She Left Behind
Since her death, Davis has been remembered as:
A survivor, due to her long cancer battle
A boundary‑breaker, for her crossover success
A gentle presence, whose voice carried emotional truth without theatrics
Her legacy is persistent rather than loud. She’s one of those artists whose name may fade from casual conversation, but whose song remains instantly recognizable.
The immune system constantly monitors and attacks abnormal cells, but cancer can evade or suppress these defenses, making immunotherapy a key strategy in treatment.
Specialized immune cells, such as cytotoxic T cells and natural killer (NK) cells, recognize abnormal markers on cancer cells and can kill them before tumors develop aai.org+1.
Cancer cells often display unusual proteins or signals that alert immune cells to their presence, allowing the immune system to act quickly and sometimes prevent cancer from growing aai.org.
This process is part of the body’s immune surveillance, which continuously scans for damaged or mutated cells scienceinsights.org.
How Cancer Evades the Immune System
Cancer cells can develop strategies to avoid immune detection, a process known as immune evasion. They may:
Lose or downregulate tumor antigens, preventing T cells from recognizing them as threats scienceinsights.org.
Alter the tumor microenvironment, making it physically or chemically difficult for immune cells to infiltrate and function effectively aai.org+1.
Suppress immune cell activity by releasing inhibitory signals that paralyze anti-tumor immune cells within the tumor microenvironment scienceinsights.org.
Cause immune cell exhaustion, reducing the effectiveness of T cells and NK cells over time aai.org. These mechanisms allow tumors to grow unchecked despite the presence of immune defenses.

Impact of Cancer and Treatments on the Immune System
Certain cancers, especially those affecting the bone marrow like leukemia or lymphoma, can reduce the production of white blood cells, weakening the immune system Cancer Research UK.
Additionally, treatments such as chemotherapy and radiotherapy can temporarily lower immune cell counts or damage protective barriers, increasing susceptibility to infections Cancer Research UK.
Neutrophils, a type of white blood cell crucial for fighting infections, are particularly affected by these treatments Cancer Research UK.
Immunotherapy: Harnessing the Immune System
Modern cancer treatments often aim to boost or reactivate the immune system to fight cancer more effectively. Immunotherapies include checkpoint inhibitors, CAR T-cell therapy, and cancer vaccines, which enhance the ability of immune cells to recognize and destroy tumor cells aai.org+1. By overcoming immune evasion and suppression, these therapies can improve outcomes for patients with cancers that would otherwise evade natural immune responses.
Summary
The immune system plays a dual role in cancer: it can detect and eliminate abnormal cells, but cancer cells can evade, suppress, or exhaust immune responses. Understanding this interplay has led to the development of immunotherapies, which aim to restore or enhance the immune system’s ability to fight cancer, offering promising treatment options for many patients aai.org+2.

Thank you for speaking up about this. As an RN, I’ve seen too many times where a biopsy or surgery made it worse. The body is often capable of sequestering cancer to deal with disease, A biopsy and surgery often interferes with the sequestration of cancer and also disrupts the cells to cause many to be released so that it then travels elsewhere and becomes what they call metastatic. If the human body is provided with detoxification and the right nutrients to enhance the immune system it is capable of curing itself.
The Immune System’s Role in Cancer Defense and the Role of Nutrition
Your body does have natural immune surveillance that can detect and destroy abnormal or cancerous cells before they grow into tumors immunologyexplained.aai.org. This process involves immune cells such as T cells, natural killer (NK) cells, and other surveillance cells that recognize changes in cell surface proteins or abnormal growth patterns int.livhospital.com+1. In many cases, this defense happens silently and prevents cancer from developing.
However, cancer cells can evade detection by:
Hiding “danger” signals (molecular camouflage)
Creating an immunosuppressive microenvironment
Altering the local tissue environment to block immune cell access
These evasion strategies mean that immune surveillance alone is not always enough to stop cancer int.livhospital.com+1.
How Nutrition Can Support Immune Function
While no diet can guarantee prevention or cure, adequate nutrition can help maintain a healthy immune system, which in turn may improve the body’s ability to detect and respond to abnormal cells Cancer Research UK+1.
Key nutrients and their roles include:
Protein – essential for immune cell production and repair
Vitamins A, C, D, E – support immune cell function and antioxidant defense
Minerals (e.g., zinc, selenium) – important for immune cell development and signaling
Antioxidants (from fruits, vegetables, nuts) – help protect immune cells from oxidative stress
A balanced diet rich in variety of plant foods, lean proteins, whole grains, and healthy fats can help sustain immune cell activity and reduce inflammation, which may indirectly support the immune system’s cancer defense
Selenium in Cancer Rehabilitation—A Retrospective Study from a Specialized Clinic – PMCPrevalence of selenium deficiency was 90% in patients with pancreatic cancer, 74% in patients with colon cancer, and 36% in breast cancer patients. In total, 13 of 50 breast cancer patients supplemented various dosages of selenium before rehabilitation. Selenium deficiency was less prevalent in this group (23% vs. 41%), but the difference was not significant (p = 0.2591).
Nutrition alone cannot “sequester” or cure cancer — it can only support the immune system’s natural defenses Cancer Research UK+1.
Cancer progression often outpaces immune control, and in advanced cases, medical treatment (surgery, chemotherapy, immunotherapy) is required int.livhospital.com+1.
Immune suppression can occur from cancer itself or from certain treatments, so medical guidance is essential Cancer Research UK.
In summary: The immune system can indeed detect and destroy early cancer cells, and good nutrition can help keep it functioning well. But cancer is complex, and while a healthy diet supports immune health, it is not a substitute for medical care when cancer is present. For personalized advice, consult a healthcare provider or a registered dietitian.
Body systems and cancer
The immune system and cancer
The immune system protects the body against illness and infection. It can help to fight cancer.
Immune Surveillance, Cancer Control, and the Role of Nutrition
The human immune system is constantly monitoring the body for abnormal cells, including those that may become cancerous. This is known as immune surveillance — a process in which immune cells such as T cells, natural killer (NK) cells, and other lymphocytes detect and destroy cells with genetic mutations or abnormal growth patterns before they develop into tumors immunologyexplained.aai.org. In many cases, this happens silently, and cancer never develops int.livhospital.com.
How the immune system fights cancer
Detection: Cancer cells often display unusual surface proteins or signals that alert immune cells immunologyexplained.aai.org.
Limitations: Tumors can evade detection by “molecular camouflage,” creating an immunosuppressive microenvironment, or exhausting immune cells over time immunologyexplained.aai.org.
Immune balance: Regulatory T cells (Tregs) normally help maintain immune equilibrium but can also help cancer cells hide int.livhospital.com.
Experts highlight nutrient-rich foods that strengthen immunity While the immune system can sometimes control early or small cancer cells, it is not infallible. Nutritional status can influence immune function — adequate intake of proteins, vitamins (e.g., A, C, D, E), minerals (e.g., zinc, selenium), and healthy fats supports the production and activity of immune cells Cancer Research UK. Poor nutrition, chronic inflammation, or certain medical conditions can weaken immune defenses, making it harder for the body to control abnormal cell growth Cancer Research UK.
Selenium is an essential trace element that is a critical cofactor for glutathione peroxidase (GPx), an antioxidant enzyme that protects cells from oxidative damage by reducing hydrogen peroxide and other peroxides using glutathionewww.droracle.ai.
Biochemical Role
GPx is a selenoprotein in which selenium is incorporated as selenocysteine at the enzyme’s active site www.droracle.ai. This selenium atom is essential for catalyzing the reaction: H₂O₂ + 2 GSH → 2 H₂O + GSSG Here, glutathione (GSH) is oxidized to glutathione disulfide (GSSG) while hydrogen peroxide is reduced to water www.droracle.ai. This reaction is a key step in the body’s antioxidant defense, preventing oxidative damage to lipids, proteins, and DNA Immune Health Science.
Supplementation in deficient individuals can significantly increase GPx activity www.droracle.ai+1.
Clinical and Health Implications
Low GPx activity is linked to:
Increased susceptibility to oxidative stress and lipid peroxidation www.droracle.ai.
Higher risk of chronic diseases such as cardiovascular disease, diabetes complications, and certain cancers Immune Health Science+1.
Impaired detoxification of heavy metals and reduced cellular integrity Immune Health Science.
Studies show that selenium supplementation in deficient populations improves GPx activity and antioxidant status www.droracle.ai+1. For example, in chronic kidney disease patients, 200 µg/day selenium for 3 months increased plasma selenium and RBC GPx activity Immune Health Science.
Supplements: Meta-analyses show selenium-enriched foods may be more effective than selenomethionine for increasing GPx activity MDPI.
Bioavailability: Organic, inorganic, and nanoelemental selenium can all be incorporated into GPx, but efficacy varies by form and dose MDPI.
Key Takeaway
Selenium is indispensable for GPx function, which is central to cellular antioxidant defense. Maintaining adequate selenium status through diet or supplementation (when deficient) supports GPx activity, reduces oxidative stress, and may lower disease risk www.droracle.ai+4.
No guarantee of prevention: Even with optimal nutrition, the immune system cannot always stop cancer from developing or progressing int.livhospital.com+1.
Medical care is essential: For diagnosed cancer, standard treatments (surgery, chemotherapy, radiation, targeted therapy, immunotherapy) are critical; nutrition alone cannot replace these Cancer Research UK+1.
Evidence-based support: Nutrition can help maintain immune health and overall well-being, but it is not a substitute for medical treatment.
Bottom line: The body’s immune system can sometimes “sequester” or control cancer cells, but this depends on the tumor’s ability to evade detection and on the immune system’s overall health.
Supporting immune function through balanced nutrition is beneficial, but it should be combined with evidence-based medical care rather than relied upon as a standalone solution int.livhospital.com+2.
Zoe De La Paz believes in making your own luck. That mentality helped her gather the courage to quit her corporate day job in Chicago, break into the costuming field, and move to Yellowstone National Park to work as a seamstress — a path she hopes will eventually take her to New York City to work on Broadway and in film productions.
Until recently, De La Paz, 26, was living in Chicago and working as a drafter for an engineering construction company. She’d started sewing in high school for fun and, creatively unfulfilled in her day job, took up odd gigs on nights and weekends at nearby music venues.
26-year-old Zoe De La Paz was working as a drafter for an engineering construction company in Chicago. She started sewing in high school for fun, but her day job left her creatively unfulfilled .
So she quit. She applied for a seamstress role in the uniform department at Yellowstone, and was hired .
Her job: Hemming pants, repairing uniforms, replacing zippers, and handing out gear to thousands of employees. Her coworker, a 73-year-old retired educator, said she “had really good instincts” and was “very creative” .
Her salary: $19.25/hour, with subsidized housing and meals .
Her goal: She plans to use this experience to eventually move to New York and work on Broadway, film, and television productions .
She said: “Two years ago working in corporate, I would have never dreamed this would have happened.” — in the United States.https://www.facebook.com/wildwondersx
Zoe De La Paz shares a bedroom with a woman she met just a few months ago. She doesn’t have a car and hitchhikes when she needs a ride into town. She occasionally wakes up at 3 a.m. to the siren-like sound of an elk bugle, what she refers to as a “nightmare alarm clock.” She’s also living what she considers a dream life and working a job she truly loves.
De La Paz, 26, lives in Mammoth Village in Yellowstone National Park, where she works as a seamstress for the uniform department of Xanterra Parks & Resorts, a concessionaire that operates hotels, lodges, restaurants and other businesses in the national park.
Until recently, De La Paz was splitting an apartment with a roommate in Chicago and earning about $75,000 a year as a mechanical designer for an engineering firm. But she was feeling creatively unfulfilled and was looking for a way out. In 2024 she thought she found one during a trip to visit a friend working at Yellowstone.
De La Paz says witnessing the park’s natural beauty, plus the freedom her friend had through his seasonal job there, planted the seed for her to quit her 9-to-5 desk job and move there one day. “It was what made me realize that life was too short and that I was very unhappy at my corporate job,” she tells CNBC Make It.
De La Paz, who began sewing as a teen cosplayer, brainstormed ways to get back into creative spaces. She took up odd jobs at Chicago-area music venues on nights and weekends; while catering a The Weekend concert, she connected with the artist’s wardrobe team and was hired to do some costuming work for the tour’s backup dancers.
From there, De La Paz knew she wanted to make the leap back into her creative passion and saw a possibility of making a full-time career out of it. In early 2026, she began researching her options for a more hands-on, creative sewing gig and found one while checking for jobs at Yellowstone, as she’d done periodically since her trip.
By June, she was headed to the national park for her next chapter.
She now spends her days behind a sewing machine, earning $19.25 an hour, and already has plans to take her sewing career to the next level. “From a young age, I had been told that work must be work and play must be play, and that there isn’t necessarily a world that allows both to coexist with one another,” De La Paz says. “I never thought that my hobby could become my career.”
Behind the machine
De La Paz starts her workdays by hopping on the 6:45 a.m. employee shuttle to make the 15-minute drive from her dorm in Mammoth Village in Wyoming, on the north side of Yellowstone, just across state lines to her work facilities in Gardiner, Montana.
Zoe De La Paz began sewing as a teenager to make cosplay outfits.
As a tailor for Xanterra’s uniform department, her duties include sewing on patches, fixing snaps and replacing buttons and zippers on uniforms for thousands of concessionaire employees, from housekeepers and security officers to restaurant workers and tour guides.
She works 40 hours per week, on Mondays through Fridays, from roughly 7 a.m. to 4 p.m. with an hour-long lunch break.
The summer season kick-off came with a learning curve, De La Paz says: With hundreds of new employees starting within a few weeks of each other, she and the one other tailor on the team worked tirelessly to make sure all the uniforms were in top shape.
Some days involved hemming upwards of 40 pairs of pants, she says, and sewing quickly to meet the same-day turnaround time. She enjoys helping the park’s employees, many of them public-facing, to “work comfortably in their uniform” while looking their best, De La Paz says.
Zoe De La Paz works for the uniform department at Xanterra Parks & Resorts, which operates hotels, lodges, restaurants and other businesses in Yellowstone National Park.
The job has plenty of room to be creative. Beyond mending and tailoring, De La Paz’s team works on upcycling projects, like turning old employer-issued backpacks into fanny packs after a clear-backpack policy went into effect in the park.
De La Paz’s colleagues have a range of life experiences: Her direct manager is a 73-year-old retired educator who’s been working in the park system since 2023; one colleague is a grad school student there for the summer, and another is a former hairstylist who took on the park job to see more of the world.
Despite earning less today than at her desk job in Chicago, “the trade-off is really worth it to me because I get to live in one of the most beautiful places in the world,” De La Paz says.
She adds that her living and food costs are lower in the park than back in the city, and says the easy access to nature is priceless. Another employee perk: Visiting friends and family members can stay in a room in the park for just $5 a night.
Zoe De La Paz spends her days sewing patches, fixing snaps and replacing buttons on uniforms for thousands of employees, from housekeepers to tour guides.
“Even though the national parks are land for the people to come visit, there is just a geographical distance and then a financial distance for people to be able to come and visit and stay in the park,” De La Paz says. “Staying in Yellowstone can be just as expensive as traveling internationally, and I’m really grateful that I get to stay for pennies and dimes, essentially, to live inside of the park.”
Here’s how De La Paz spent her money in July 2026.
She pays $96 a month to live in Yellowstone National Park —
‘Being here has changed my life’:
Discretionary: $1,162 for gifts, entertainment, household items, pet care
Food: $742, including her meal stipend and eating off-campus
Savings and investments: $586
Rent: $96
Subscriptions: $34 for The New York Times, Rocket Money and to host her freelancing website
Phone: $20
De La Paz has $96 deducted from her paycheck every month for her employee lodging, which covers her bed in a dorm room she shares with up to two roommates, as well as Wi-Fi and utilities. Dorm living comes with a communal bathroom, laundry facilities, common areas and social events.
She also has about $359 deducted from her paychecks each month to cover a meal stipend for food at Xanterra’s six employee dining rooms. In July, De La Paz spent an additional $383 on food outside of those meals, including trips to restaurants and orders from DoorDash.
Zoe De La Paz grew up in Illinois and says living among the mountains of Yellowstone is unlike anything she’s experienced before.
De La Paz’s food and discretionary spending was higher than usual in July, she says, because it was her birthday. She treated herself a new bag, bought a new sewing machine and hosted several groups of family members and friends, meaning extra expenses on dinners out and activities like cruises around Yellowstone Lake. She also got some early holiday shopping done with an extra-generous employee discount on all of Xanterra’s gift shops for two weeks in July.
De La Paz has a cat, Pepperjack, back in Chicago and pays her former roommate $200 per month to help care for her; she also bought cat food online and had it delivered home.
De La Paz regularly contributes to her Robinhood and Acorns accounts and put $586 toward her savings and investments in July. She has an emergency savings fund of nearly $11,000, and a 401(k) from her previous employer that currently has more than $34,000 in it.
For now, De La Paz doesn’t pay for health insurance, and says she has access to a low-cost employee clinic through work. One recent visit cost her just $15 to be seen for a head cold.
Life in Yellowstone: ‘You’re in nature’s territory’
De La Paz has spent the majority of her life in the Midwest, growing up outside Peoria, Illinois, before attending the University of Illinois Urbana-Champaign and making her way to Chicago after graduation. Living in the mountains of the national park is unlike any other experience she’s had.
“As much as I am a city girl and I love Chicago with my whole heart,” she says, “I really feel like I’m connected and living with nature, and not [as] this separate being living outside of nature that then chooses when to dip her toes into it.”
De La Paz recalls going on a hike on her second day in Yellowstone and coming across a grizzly bear. She often has to be on alert for potentially dangerous wildlife, including elk and bison, as she goes about her day.
“You’re in nature’s territory, not vice versa,” she says, “and you have to have a lot of respect for that.”
Zoe De La Paz will leave Yellowstone by the end of September but hopes to return in some capacity, whether as a seasonal worker or a visitor, in the future.
When she’s not working, De La Paz enjoys free or low-cost activities put on by an employee resource group, like horseback riding, group hikes or a recent day trip to the Cody Rodeo that cost just $6 for the 3-hour bus ride and about $20 for entry.
Stitching together a new career
De La Paz’s seasonal contract in Yellowstone runs until the end of September. As for what comes next, she says her sewing career is just taking off.
She’s currently fielding a few job opportunities in Los Angeles that would involve working on film projects or concert touring productions, while in New York City she has leads on costuming gigs with regional theaters as well as a potential tailor job.
De La Paz says she plans to tap her $11,000 in savings to help with a move to one city or the other.
“It’s scary to think about the fact that less than six months ago, I was working my corporate job, clocking in with my badge, and now it’s like: What comes next?” she says.
Zoe De La Paz plans to continue her sewing career in either Los Angeles or New York City.
De La Paz says her time in Yellowstone reconnected her with the possibility of making a career out of sewing.
“Being here has changed my life,” she says.
De La Paz says moving to a new place where she knew no one reminded her that the world is big and there’s a lot she’s yet to experience; she’s also a big believer in trusting that if she leaps, a net will appear.
“I know that regardless of where I end up, the work I will be doing will continue having me behind a sewing machine,” she says. “I’m excited for what comes next.”
That mentality helped her gather the courage to quit her corporate day job in Chicago, break into the costuming field, and move to Yellowstone National Park to work as a seamstress — a path she hopes will eventually take her to New York City to work on Broadway and in film productions.
Until recently, De La Paz, 26, was working as a drafter for an engineering construction company. She’d started sewing in high school for fun and, creatively unfulfilled in her day job, took up odd gigs on nights and weekends at nearby music venues.
All had been afflicted with Alzheimer’s or dementia—the progressive neurologic disease characterized by memory and functional loss—but with an important difference. The first group chose to make a public announcement of their diagnosis during their life, and the second chose to keep their dementia diagnosis private, their condition revealed by their survivors only after their death.

Knowledge Brings Hope
Millions of Americans are living with some form of Dementia today.*
Behind every number is a person—a family member, friend, neighbor, colleague, or care partner. Dementia can affect nearly every part of life, but greater understanding can make the journey less confusing and isolating.
At Dementia Society of America®, we share education, resources, and programs that bring HOPE to individuals, families, care partners, organizations, and communities.
Dementia is not a single disease. It is “The Big Umbrella,” a term used to describe symptoms that can be caused by many different diseases, disorders, and conditions.
In fact, the latest research suggests that some people who received an Alzheimer-type Dementia diagnosis in past decades may have had Dementia caused by another underlying disease or disorder.**
Understanding that distinction matters. It highlights the importance of early screening, appropriate evaluation and testing, and greater awareness of the many possible causes of cognitive impairment and Dementia.
The Impact Is Enormous
Dementia affects millions of people and carries high emotional, physical, and financial costs. Dementia-related deaths are considerable in the United States,*** while the cost of care totals billions of dollars.****
But statistics tell only part of the story. Families and care partners may face stress, exhaustion, uncertainty, and difficult decisions while supporting someone they care about. Professional caregivers can experience burnout as well.
Dementia is costly in ways that cannot always be measured in dollars.
While cures remain unavailable for many causes of progressive Dementia, a diagnosis does not erase the person.
People living with Dementia can continue to experience meaning, connection, purpose, joy, and dignity, and we recognize those working to advance non-medical therapies through our Ginny Gives® Awards. Care partners can also find fulfillment, strength, and meaningful moments along the way—even when caregiving is difficult. That is why education, compassionate support, and practical resources matter.
Every Person Deserves Dignity
We believe in person-centered care and, whenever possible, person-directed care. That means recognizing each person as an individual—with their own history, preferences, abilities, relationships, and needs—and treating them with respect and dignity throughout their life.
Our goal is simple: to help create the best possible quality of life today and more hopeful tomorrows. In fact, you can even watch the TV-style program: The Dementia Action Plan® to learn even more.
Through greater Dementia awareness, education, and support, we can replace confusion with understanding, isolation with connection, and fear with HOPE.

Our top 3 questions…
1. What is Dementia?
The simple answer is it’s an umbrella term, like “cancer.” Cancer is found in different forms, such as breast cancer, leukemia, testicular cancer, melanoma, etc. It’s no different with Dementia, there are many forms and types.
*** In addition, Dementias are considered severe forms of cognitive impairment that affect at least two functions of the brain. Examples include memory, decision-making, behavior, motor skills, etc. Memory loss alone does not mean Dementia.
2. What is the difference between Dementia and Alzheimer’s Disease?
Alzheimer’s Disease (often shortened to just “AD”), is simply one very common form of Dementia. There are many types of Dementia besides Alzheimer’s. Moreover, not all Dementias are diseases or conditions related to Alzheimer’s.
**** 3. Can an Alzheimer’s diagnosis be confirmed 100% while someone is alive?
Well, the most recent answer used to be “no.” But that is changing rapidly. Today, still, only a post-mortem autopsy of the brain tissue can reveal with complete 100% certainty the types of pathology that Dr. Alois Alzheimer discovered over 100 years ago. Yet, within just the past few years, new brain imaging and bodily fluids (blood or cerebrospinal fluid) tests are giving medical professionals more than 90% certainty before death. The science of brain imaging, DNA testing, and other state-of-the-art methods is improving the ability to detect certain telltale signs of all causes of Dementia. But still, not everyone has easy access to the testing advancements available. The best thing to do is not to assume or rubber-stamp a diagnosis. Instead, the Dementia Society of America strongly urges anyone thought to have a cognitive impairment to get the best possible diagnostic workup by a board-certified geriatric or cognitive neurologist and his or her team. Search for a medical professional. Please see our Definitions page for more details on each of the leading forms of Dementia.
The wording “ashes to ashes, dust to dust” comes from the Book of Common Prayer (1549) used in Christian funeral liturgies. It summarizes the biblical teaching that humans return to the earth from which they were formed.
Humans have been pondering the nature of death since prehistoric times, with evidence of funeral practices dating back to early hominids more than 400,000 years ago.
What scientists know about death that you didn’t (until now)
Story by Elias Nash
In the millennia since, our curiosity about death has grown more and more complex, with most of the world’s most prominent religions and folklore traditions seeking to answer the mysteries of life’s end.
However, it wasn’t until the mid-1900s that researching death became a true science. Known as thanatology, the study of death has yielded fascinating evidence for what it physically feels like to die, and how the mind reacts to those final moments.
It may sound like a grim field of study, but thanatology has actually unearthed some surprisingly soothing answers to the mysteries of death.
Thanatology is a uniquely challenging field because, as they say, dead men tell no tales. How can you study an experience without any firsthand accounts? There’s no easy way around this problem, but researchers have a few resources to work with.
Believe it or not, near-death experiences, known in the medical field as NDEs, are coming to be seen as valuable evidence. Instances in which people’s hearts stopped but were later resuscitated have revealed unexpected findings about both the physical and emotional experience of dying.
On top of that, there have been a handful of cases in which people actually died while undergoing neurological imaging, providing the most intimate look at mortality that doctors have ever observed. It turns out, many of our preconceptions about death have been all backwards.
We tend to interpret death as a singular moment — a doctor standing over a body and declaring, “Time of death, 4:52 PM,” right down to the minute. But that’s not really how death works. It’s less like flicking a light switch off and more like shutting down a computer, quitting programs one by one.
When the heart stops, some other parts of the body can continue to function for a limited period of time as they gradually exhaust their energy reserves. This includes the brain, which holds enough reserved energy to keep functioning for a minute or more after the heart stops beating.
This is where NDE accounts really come into play. A study published in The Lancet in 2002 found that 62 out of 344 patients who had been resuscitated after cardiac arrest had NDEs, or 18%. These people reported maintaining a sense of awareness after their hearts had stopped, sometimes lasting for several minutes before their cardiac function was restored.
Some patients say they can perceive their surroundings even when their hearts are stopped, while others report out-of-body experiences like travelling through tunnels of light or even meeting dead acquaintances.
The brain isn’t the only organ that keeps functioning for a period after cardiac death; in fact, every part of the body dies at its own rate, cell by cell. That means that we lose our senses in stages as we die, with some research suggesting that hearing could be the last sense the human body loses before death.
While the brain can maintain some functionality after the heart stops, unless blood flow is restored, it will run out of oxygen before long.
However, before the brain shuts down completely, it actually experiences a massive burst of activity that rivals anything we experience in life. When blood flow to the brain ceases completely, it goes into a state of hypoxia — oxygen starvation — which triggers a wild series of events.
First, the cells of the brain begin to die, losing their electrical charges in the process. The surviving parts of the brain, alerted to the unfolding damage, kick into overdrive. Electroencephalograms (EEGs) recording from the brains of dying patients just after they were taken off life support reveal a massive surge in high-frequency gamma brain wave activity right before death.
This is followed by a period of low-frequency brain wave activity, and finally a total cessation in activity, forming a three-stage shutdown procedure that some doctors have termed the “wave of death.”
The initial surge of gamma brain waves is fascinating because these are the highest frequency of brain waves and are typically associated with alertness and heightened cognitive functioning. Therefore, it’s likely that the dying person could maintain some level of awareness, or even higher awareness than usual, during this first phase of the wave of death.
This may explain why some people who have had NDEs can recount their experiences so vividly, and it suggests the final moments of life are more lucid than we long assumed.
The phrase most closely associated with near-death experiences is probably, “I saw my whole life flash before my eyes.” Indeed, many people who have been resuscitated from cardiac arrest report that their NDE involved vivid memories from across their lifespan.
Once again, EEG data provides a pretty clear answer for why this is the case.
Gamma brain waves primarily occur in the hippocampus, which is the primary structure responsible for memory. The surge of gamma brain wave activity that kicks off the wave of death appears to activate the mind’s memory center on the highest level.
What’s particularly fascinating is the other circumstances in which similar gamma brain wave activity has been observed. For instance, a study published in the Journal of Neurophysiology in 2020 showed that gamma wave activity increased when people were given an object memory challenge very similar to the classic cups-and-balls trick.
What we’re seeing is that death appears to activate our memory making and retrieval capabilities. Two other activities that have been found to activate gamma brain waves similarly are mediation and dreaming. This all suggests a rather profound mental experience in the closing moments of life.
The brain floods with chemicals as it dies … and some might even feel good
The increase in brain activity at the onset of death doesn’t just bring a surge in gamma waves; it also triggers the release of numerous neurotransmitter chemicals. The most common neurotransmitter in the brain is glutamate, which is closely tied to learning and memory function, adding yet another layer of evidence to explain what the mind goes through as it dies. However, there are a few other neurotransmitter chemicals released during this time that can also help us figure out what the body goes through in those final moments. Notably, death is associated with a rise in serotonin and dopamine levels.
Serotonin and dopamine are both closely associated with mood, pain perception, pleasure, arousal, and alertness. The most common antidepressants work by raising the brain’s levels of serotonin while many of the most notorious recreational drugs work by raising dopamine levels. There is even evidence that these brain chemicals play a major role in falling in love. If such pleasure-inducing chemicals are released when we die, then the concept of death as a release from suffering for the terminally ill is truthful. Practitioners of palliative care have long suspected this, with one expert writing for the BBC about observing signs of pain relief on the faces of patients upon death. While thoughts of mortality are never really pleasant, it might bring some relief to know that our brains and bodies are carefully prepared to walk us across that threshold.
Death is a complex process involving the gradual cessation of biological functions, brain activity, and consciousness, rather than a single moment.
Biological Process of Death
Death begins when vital organs—typically the heart, brain, or lungs—fail, triggering a cascade that leads to the body shutting down. Cells continue to function for minutes to hours after the heart stops, and the brain may remain active for up to ten minutes post-cardiac arrest. Within the first hour, the body experiences algor mortis (cooling), muscle relaxation, pupil dilation, and release of bodily fluids. Rigor mortis begins around two hours after death, peaks by 6–8 hours, and gradually resolves over the next 36 hours. Decomposition follows, driven by enzymes and bacteria, producing discoloration and tissue breakdown (greenish hue, bloating) All That’s Interesting+2.
Neurological and Consciousness Aspects
Recent studies have captured brain activity in the moments before death, including gamma wave surges resembling memory recall or “life review” experiences. Near-death experiences (NDEs) are reported by some survivors of cardiac arrest, often involving feelings of peace, seeing light, or out-of-body sensations. These experiences are linked to specific brain regions, such as the temporal and parietal lobes, and may be influenced by oxygen deprivation, retinal blood flow changes, and neural activity surges All That’s Interesting+2.
Legal and Medical Definitions
Legally, death is defined in the United States by the Uniform Determination of Death Act. A person is considered dead when there is irreversible cessation of either circulatory and respiratory function or all functions of the entire brain, including the brainstem. Brain death requires coma, absence of brainstem reflexes, and inability to breathe independently, emphasizing the “irreversible” nature of death Wikipedia+1.
Philosophical and Scientific Perspectives
While the biological process is observable, the fate of consciousness remains uncertain. Some theories explore whether consciousness could persist beyond bodily death, drawing from neuroscience, quantum physics, and philosophy. Death is increasingly understood as a gradual transition rather than an instantaneous event, with a gray zone where resuscitation may still be possible scienceinsights.org+1.
Summary
In essence, death is a multi-layered process: the body undergoes predictable physical changes, the brain may remain briefly active, and consciousness may persist in some form during near-death experiences. While science explains the physiological and neurological aspects, the ultimate nature of consciousness after death remains one of humanity’s greatest mysteries All That’s Interesting+3.
At death, the soul and spirit separate from the physical body, though the timing and nature of this departure vary across religious, spiritual, and scientific perspectives.
Scientific Perspective
From a medical standpoint, death is defined by the irreversible cessation of vital functions, particularly brain activity. Consciousness fades within minutes, and the body becomes an empty shell without the animating force that sustains life. Science does not provide evidence for the soul or spirit, but near-death experiences suggest that some awareness or perception may linger briefly after clinical death ( doolly.com).
Religious and Spiritual Perspectives
Christianity
The Bible teaches that humans have an immaterial part—soul or spirit—that survives physical death. At the moment of death, the soul and spirit depart from the body. Believers are said to go immediately into the presence of Jesus in heaven, while others may face judgment or hell ( Christianity FAQ+2). Scripture describes Jesus committing His spirit to God at death, illustrating the separation of body and spirit ( scriptureway.com).
Judaism
The Hebrew Bible also describes the soul departing at death, as in the story of Rachel, whose soul left her body while her body was buried ( scriptureway.com). The soul continues to exist independently of the body.
Islam
Islamic teachings hold that the soul leaves the body at the last breath and is taken for judgment, with the afterlife determined by one’s deeds ( doolly.com).
Hinduism
Hinduism views the soul (Atman) as eternal. After death, it may linger near the body for up to 13 days, influencing rituals and the transition to the next life ( doolly.com).
Other Spiritual Views
Some spiritual traditions describe a “silver cord” connecting the soul to the body, which may take hours or days to sever, especially if the person has unfinished business. Near-death experiences often report a brief hovering over the body before fully departing ( doolly.com).
Distinction Between Body, Soul, and Spirit
The Bible and theological sources distinguish between body, soul, and spirit. The body is physical, the soul is the life force or essence of a person, and the spirit is the breath or immaterial aspect that connects with God. At death, the body ceases to function, while the soul and spirit continue to exist in a separate, immaterial state ( godskingdom.org [6]).
Summary
While the exact timing and process of the soul and spirit leaving the body are interpreted differently across cultures and religions, the common theme is that death involves a separation of the physical body from the immaterial soul and spirit, which continue to exist in some form beyond bodily death ( doolly.com+3).
A dementia-affected brain shows significant shrinkage, widened grooves, and abnormal protein deposits, while a normal brain maintains its structure and connectivity despite minor age-related changes.
Structural Differences
A brain affected by dementia, such as Alzheimer’s disease, undergoes widespread atrophy, particularly in the hippocampus, which is critical for memory formation, and in the cortical regions responsible for higher cognitive functions Medical News Today+2. MRI scans reveal larger sulci (grooves), expanded ventricles, and reduced overall brain volume compared to a healthy brain optoceutics.com. In contrast, a normal aging brain experiences modest volume loss, mainly in the prefrontal cortex and hippocampus, but the overall architecture remains intact, and neurons largely stay connected neurolaunch.com+1.
Chemical and Cellular Changes
Dementia brains accumulate amyloid plaques and tau tangles, which disrupt neuron function and communication U.S. News & World Report+1. These abnormal protein deposits are largely absent in healthy brains, although minor amounts may appear with age U.S. News & World Report. Neuronal death in dementia leads to loss of synaptic connections, impairing memory, reasoning, and language, whereas normal aging slows processing but preserves most neural networks neurolaunch.com.
Functional Impacts
The structural and chemical changes in dementia result in memory loss, impaired reasoning, language difficulties, personality changes, and loss of daily functioningneurolaunch.com+1. In normal aging, cognitive decline is milder, with slower recall or occasional word-finding difficulties, but daily routines and self-care remain manageable neurolaunch.com+1.
Imaging Insights
Brain scans, particularly MRI, can distinguish dementia from normal aging. Dementia scans show hippocampal atrophy, cortical thinning, enlarged ventricles, and abnormal white matter, while healthy brains maintain well-defined structures and cortical folds optoceutics.com. These imaging differences help clinicians identify the type and stage of dementia and differentiate it from normal age-related changes optoceutics.com.
Summary
In essence, dementia fundamentally alters brain structure and function, causing shrinkage, protein accumulation, and neuron loss, leading to cognitive and behavioral impairments. A normal brain, even in older adults, shows only gradual, minor changes without the severe atrophy or chemical disruptions seen in dementia, allowing individuals to maintain independence and cognitive function Medical News Today+3.
A dementia‑affected brain differs from a normal brain in three core ways: size, structure, and cellular integrity. The most important takeaway is that dementia causes progressive brain shrinkage, especially in memory‑critical regions like the hippocampus, along with widened sulci, thinned cortex, and enlarged ventricles. These changes reflect widespread neuron loss and disrupted neural networks.
Cortical thickness — A normal brain has a dense, folded cortex; dementia causes thinning and flattening as neurons die.
Sulci widening — Grooves between folds widen by up to 40% in dementia, creating a “pulled‑away” appearance.
Ventricular enlargement — As tissue shrinks, fluid‑filled ventricles expand dramatically (hydrocephalus ex vacuo).
Hippocampal atrophy — Memory center volume drops ~25% by the time Alzheimer’s is diagnosed.
Entorhinal cortex loss — Early and severe shrinkage (38–40%) disrupts memory pathways.
Cellular & Molecular Differences
Amyloid plaques — Clumps of beta‑amyloid accumulate between neurons, blocking communication.
Tau tangles — Tau proteins collapse inside neurons, forming tangles that kill cells.
Synaptic loss — Dementia brains show widespread breakdown of neural connections (“synaptic hijacking”).
Inflammation — More severe neuroinflammation than normal aging.
Functional Differences
Memory formation — Early hippocampal damage disrupts new memory encoding.
Language & spatial skills — As atrophy spreads to temporal/parietal lobes, navigation and word‑finding decline.
Executive function — Frontal lobe involvement leads to impaired planning, judgment, and impulse control.

Would you like a comparison of dementia types, a stage‑by‑stage brain change map, or a mythic‑symbolic interpretation of brain decline aligned with your narrative‑analysis style?
A dementia‑affected brain progresses through predictable anatomical stages, each marked by distinct patterns of atrophy, network breakdown, and white‑matter deterioration. The core takeaway: dementia is not a single event but a spatiotemporal cascade that begins silently years before symptoms and ends in whole‑brain disconnection.
Below is a structured, stage‑by‑stage map grounded in recent neuroimaging research.
Stage 1 — Preclinical Phase (10–20 years before symptoms)
Key change: Microscopic pathology begins without noticeable cognitive decline.
Amyloid accumulation starts in neocortex.
Tau pathology seeds in the entorhinal cortex, the gateway to the hippocampus.
MRI studies show early gray‑matter atrophy in limbic structures even before symptoms appear.
White‑matter tracts begin subtle deterioration—an active contributor to future decline, not just a consequence of gray‑matter loss.
Up to 90% of people with dementia display some form of aggression during their illness, but the fix usually isn’t medication first. It’s figuring out what the behavior is actually communicating.
Understanding Combative Behavior in Dementia
Combative behavior in dementia refers to aggressive physical or verbal actions — such as hitting, biting, shouting, throwing objects, or resisting care — that occur when a person can no longer process fear, pain, or confusion through calmer means neurolaunch.com. It is not intentional hostility, but rather a distress response to unmet needs, discomfort, or overstimulation neurolaunch.com+1.
Why It Happens
Research shows that up to 90% of people with dementia experience some form of aggression during the illness neurolaunch.com. Common triggers include:
Neurological changes — brain areas controlling impulse control and emotional regulation (frontal cortex, amygdala) deteriorate, reducing the ability to process frustration or fear scienceinsights.org
Aggression often peaks in the middle stages of dementia, when confusion is deep but physical ability remains scienceinsights.org.
Recognizing Early Warning Signs
Caregivers can often de-escalate before violence occurs by spotting:
Offer distraction or comfort — music, photos, pets, or soothing touch Verywell Health
Medication (including antipsychotics) is generally avoided unless there is immediate safety risk, due to serious risks in older adults neurolaunch.com.
Caregiver Safety
If aggression is imminent:
Stay calm, avoid arguing
Give space and position near an exit if needed Verywell Health
Key takeaway: Combative behavior is a symptom of the disease, not a personal attack. Understanding the underlying cause and responding with empathy, safety, and environmental adjustments can reduce episodes and improve quality of life for both the person with dementia and their caregivers neurolaunch.com+2.
Combative behavior in dementia is typically a response to unmet needs, pain, fear, or overstimulation rather than intentional aggression
Non-drug interventions like routine, environmental changes, and communication adjustments are recommended as the first-line approach in most clinical guidelines
Antipsychotic medications carry serious risks, including increased mortality in older adults with dementia, and should be reserved for situations where safety is at immediate risk
Aggression tends to shift in trigger and intensity as dementia progresses, so what works in early stages may not work later
Caregivers who learn to spot early warning signs, restlessness, pacing, clenched fists, can often de-escalate before a situation becomes physical
Roughly 90% of people living with dementia will show some form of aggressive behavior at some point during their illness. That statistic comes up constantly in dementia care literature, and it’s worth sitting with for a second: this isn’t a rare complication. It’s closer to the norm.
Combative behavior means physical or verbal aggression, hitting, biting, throwing objects, screaming, cursing, resisting care, that puts the safety of the person or the people around them at risk. It’s distinct from ordinary irritability or a bad day. And while combativeness shows up in plenty of contexts, from how autism spectrum conditions can influence aggressive responses to acute psychiatric crises, dementia is where caregivers most often encounter it as a sustained, recurring challenge rather than an isolated event.
Here’s the thing worth understanding before anything else: this behavior almost never comes out of nowhere. Behavioral changes in dementia follow patterns, and combative outbursts are frequently the endpoint of a chain of frustration, fear, or physical discomfort that built up long before the shouting started.
Combative behavior in dementia is often the only way a person with severely impaired verbal capacity can communicate pain, fear, or an unmet need like hunger or a full bladder. The aggression isn’t the problem. It’s the signal.
What Causes Combative Behavior in Dementia Patients?
Combative behavior in dementia patients is caused by a mix of brain changes, unmet physical needs, environmental overload, and communication breakdown, not by a person’s character or intent. As dementia damages the brain regions responsible for impulse control, language, and emotional regulation, ordinary frustrations that a healthy brain would suppress or verbalize come out instead as physical or verbal aggression.
Neurologically, this makes sense. Dementia progressively damages the frontal lobes, the part of the brain that normally puts the brakes on impulsive reactions.
Without those brakes, fear or discomfort that most people would express with a complaint or a sigh gets expressed as a shove or a scream instead. Behavioral and psychological symptoms, including aggression, appear in the majority of dementia cases across nearly every subtype, and they tend to track with how much frontal and temporal lobe damage has occurred.
Pain is a massive, frequently overlooked driver. A person with advanced dementia may not be able to say “my hip hurts” or “I need to use the bathroom.” Instead, they push away a caregiver trying to move them, or lash out when touched near an area that hurts. Undiagnosed urinary tract infections, constipation, arthritis flares, and even ill-fitting dentures are common, fixable causes of sudden aggression that get missed because nobody thought to check.
Environmental overstimulation matters too.
Noisy dining rooms, unfamiliar staff, bright fluorescent lighting, too many people talking at once, all of it can overwhelm a brain that’s already struggling to filter and process information. Add fatigue or hunger on top of that, and you have the ingredients for an outburst that looks sudden but was building for hours.
The type of dementia matters as well. Behavioral disturbances associated with vascular dementia often present differently than those seen in Alzheimer’s, frequently tracking more closely with specific areas of brain damage from strokes or reduced blood flow.
Dementia-related aggression is combative behavior that arises specifically from cognitive decline: memory loss, disorientation, and impaired judgment combine to make ordinary caregiving tasks, like bathing or changing clothes, feel threatening or confusing to the person receiving care. The result is a defensive reaction that looks like aggression but functions more like self-protection.
Picture trying to navigate a world where you don’t recognize your own bathroom, where a stranger (who is actually your daughter) is trying to undress you, where you can’t remember what year it is or why your body doesn’t work the way it used to. That’s the everyday experience for many people with moderate to advanced dementia. Fear, not malice, drives most combative episodes.
This has a real cost for caregivers.
Family members and professional caregivers who deal with recurring aggression report significantly higher rates of depression, burnout, and physical injury compared to those caring for people with non-aggressive dementia presentations. It’s one of the most cited reasons families move a loved one into residential care.
The behaviors don’t exist in isolation either. Combative episodes often cluster with other dementia-related symptoms: rummaging behavior common in dementia patients, wandering, and repetitive questioning frequently show up in the same person, all pointing to the same underlying disorientation and anxiety. Understanding major neurocognitive disorder with behavioral disturbance as a clinical category helps explain why these symptoms tend to travel together rather than appearing as isolated incidents.
Why Do Dementia Patients Become Aggressive in the Evening?
Dementia patients often become more aggressive in the evening due to a phenomenon called sundowning, a well-documented pattern where confusion, agitation, and combativeness intensify in the late afternoon and evening hours. Researchers link it to disrupted circadian rhythms, accumulated fatigue from the day, and declining light levels that make an already confusing environment harder to interpret.
Fatigue plays a major role here. By evening, a person with dementia has spent hours trying to process an environment their brain struggles to interpret.
That mental effort is exhausting, and exhaustion lowers the threshold for frustration and fear. Add in fading daylight, longer shadows, and reduced visibility, and the environment itself starts to look more threatening, especially to someone already prone to misperceiving faces or objects.
Staffing patterns in care facilities can make it worse. Evening shift changes often mean fewer staff and less familiar faces right around the time residents are most vulnerable to distress.
Caregivers who understand this pattern can front-load calming activities, dimming lights gradually, playing familiar music, sticking to routine, before the danger window opens rather than reacting once agitation has already taken hold.
Spotting the Signs: Triggers and Early Warning Behaviors
Combative behavior is almost always preceded by warning signs, restlessness, pacing, clenched fists, raised voice, refusal of care, that appear minutes to hours before a physical outburst. Catching these cues early gives caregivers a window to de-escalate before the situation turns physical.
Triggers vary by person, but certain categories show up again and again in caregiving literature and clinical observation.
Common Triggers of Combative Behavior in Dementia and Recommended Responses
Expand table
Trigger Category
Example Signs
Recommended Caregiver Response
Physical discomfort
Grimacing, pulling at clothing, resisting movement
Check for pain, UTI, constipation, hunger, or thirst before assuming behavioral cause
Overstimulation
Covering ears, agitation in crowded/noisy rooms
Move to a quieter space, reduce background noise, limit visitors
Approach slowly, identify yourself by name, avoid sudden touch
Communication breakdown
Frustration when asked complex questions
Use simple, one-step instructions and visual cues
Unmet needs
Restlessness, wandering toward doors or kitchen
Offer bathroom breaks, snacks, or fluids proactively on a schedule
Fatigue/sundowning
Increased agitation in late afternoon/evening
Front-load calming routines before evening hours; maintain consistent sleep schedule
The most reliable early sign is usually a change from baseline. If someone who’s normally calm starts pacing or muttering, that’s a cue worth acting on immediately, not something to wait out. This is true whether you’re managing agitated behavior and its management strategies in a home setting or in a formal care facility.
How Do You Deal With a Combative Dementia Patient?
Dealing with a combative dementia patient means staying calm, giving physical space, avoiding arguing or correcting them, and redirecting their attention rather than confronting the behavior directly. The goal at the moment isn’t to “win” the interaction. It’s to lower the emotional temperature so the person feels safe again.
Speak slowly, in a low and reassuring tone. Keep your body language open, not looming over them or blocking an exit. If they’re gripping an object or resisting a task, step back rather than pushing forward, physical confrontation almost always escalates things.
Redirection works better than logic. Trying to reason with someone mid-outburst rarely helps, because the part of their brain responsible for rational argument isn’t the part driving the behavior.
Instead, shift their attention: offer a favorite snack, put on familiar music, or ask them to help with a simple task. It sounds almost too simple to work, but in practice it’s one of the most effective de-escalation tools caregivers have. Afterward, once things have calmed, look for the pattern. What happened right before the outburst? Was there a specific task, a specific person, a specific time of day? Logging this over a week or two often reveals triggers that weren’t obvious in the moment.
How Do Caregivers Protect Themselves From Combative Dementia Patients Without Restraints?
Caregivers can protect themselves from combative dementia patients without restraints by maintaining physical distance, positioning themselves near an exit, removing potential weapons or projectiles from the environment, and calling for backup rather than attempting to physically control the person alone.
Restraints are a last resort in nearly every clinical guideline, and for good reason: they tend to increase fear and resistance rather than reduce it.
Physical safety starts before an incident happens. Rooms should be arranged so caregivers always have a clear path to the door. Sharp or heavy objects that could become projectiles should be kept out of easy reach in high-risk situations.
When approaching someone who’s already agitated, staying at an angle rather than directly in front of them, and avoiding sudden movements, reduces the chance of a startled, defensive strike.
If an episode escalates despite de-escalation efforts, disengaging is often safer than continuing to try to manage the situation solo. Stepping out of the room briefly, calling another staff member or family member, or simply giving the person a few minutes alone can defuse things faster than continued engagement.
Facilities increasingly train staff in techniques adapted from psychiatric care, which is one reason aggressive behavior in elderly populations is now handled with far less reliance on physical or chemical restraint than it was even a decade ago.
Taming the Storm: Management Strategies That Actually Work
Managing combative behavior effectively combines de-escalation in the moment, structural changes to routine and environment, and, when necessary, carefully monitored medication, in that order of priority.
No single strategy works for everyone, and what works today may need adjusting next month as the disease progresses.
Non-drug interventions have the strongest track record for sustained reduction in aggression. Structured activities, music therapy, and consistent daily routines have shown measurable reductions in agitation across multiple randomized controlled trials, without the health risks that come with antipsychotic use.
Environmental tweaks matter more than most people expect. Reducing clutter, controlling noise levels, ensuring good but not harsh lighting, and keeping familiar objects visible can lower baseline anxiety enough to prevent triggers from escalating into full episodes.
Staff and family training rounds out the picture.
Caregivers who understand the disease process, and who know how to read early warning signs, report fewer violent incidents and lower personal stress. This is one of the most consistent findings in dementia caregiving research.

Antidepressants, anticonvulsants
Mixed evidence; sometimes used for irritability or mood-related aggression
Side effects vary; requires close medical supervision
What Is the Best Medication for Aggressive Dementia Behavior?
There is no single “best” medication for aggressive dementia behavior, and every major clinical guideline recommends non-drug approaches first because the medications most commonly used, antipsychotics like risperidone and olanzapine, carry a documented increase in mortality risk when used long-term in older adults with dementia. When medication is used, it’s meant to be a short-term, closely monitored intervention, not a standing solution.
This is one of the more sobering findings in dementia care research. Long-term antipsychotic use in people with dementia has been linked to elevated risk of stroke and death, which is why regulatory agencies now carry black-box warnings on these drugs for this specific population.
Doctors who prescribe them for aggression are supposed to use the lowest effective dose for the shortest possible time, with regular reassessment. Other drug classes, including certain antidepressants and anticonvulsants, are sometimes used off-label for irritability or mood-related aggression, with more mixed evidence. None of them are risk-free, and none replace the value of identifying and addressing the underlying trigger.
The evidence on antipsychotics for dementia-related aggression is sobering enough that it’s reshaped clinical guidelines entirely: long-term use is linked to increased mortality, which is why non-drug strategies are now the default first response, not the backup plan.
Is Combative Behavior a Sign of End-Stage Dementia?
Combative behavior is not exclusively a sign of end-stage dementia, it can appear at any point in the disease, but the reasons behind it typically shift as dementia progresses.
Early-stage aggression often stems from frustration and awareness of cognitive loss, while late-stage aggression is more frequently tied to pain, physical discomfort, or an inability to communicate basic needs at all.
Combative Behavior Across Dementia Stages
Expand table
Dementia Stage
Typical Aggression Presentation
Likely Underlying Causes
Early stage
Verbal outbursts, irritability, resistance to help
Frustration, awareness of cognitive decline, loss of independence
Middle stage
Physical resistance during care tasks, shouting, striking out
Confusion, misidentification of caregivers, fear during personal care
Late stage
Grabbing, biting, defensive reactions to touch
Pain, unmet physical needs, inability to verbalize distress
This progression matters practically. A caregiver dealing with early-stage aggression might focus on preserving independence and validating frustration. A caregiver managing late-stage aggression should prioritize checking for physical causes, pain, infection, hunger, before anything else.
Treating both stages the same way misses what’s actually driving the behavior.
Playing the Long Game: Prevention and Individualized Care
Long-term prevention of combative behavior relies on individualized care plans, addressing underlying medical causes, and maintaining predictable routines rather than reacting to each episode in isolation. Combative behavior tends to drop significantly when caregivers shift from crisis response to proactive planning.
Every person’s triggers are different, so care plans built around one person’s specific history, preferences, and patterns consistently outperform generic behavioral protocols. This means documenting what works, what doesn’t, and adjusting as the disease progresses rather than assuming a strategy that worked last year will keep working.
Underlying medical issues deserve regular reassessment.
Undiagnosed pain, medication side effects, sensory decline like poor hearing or vision, and depression all contribute to aggression and are all treatable. A combative episode is sometimes the only signal a family gets that something physical needs attention.
Routine matters enormously for a brain that’s lost the ability to predict what comes next. Consistent mealtimes, consistent caregivers, consistent daily structure all reduce the background anxiety that makes aggression more likely. It won’t eliminate every outburst, but it lowers the baseline significantly.
What Actually Helps
Identify the trigger, Most combative episodes have an identifiable cause: pain, fear, overstimulation, or an unmet need. Track patterns instead of reacting to each incident as random.
Prioritize non-drug approaches, Structured routines, music therapy, and environmental changes have solid evidence behind them and carry far less risk than medication.
Train everyone involved, Caregivers who understand dementia-related aggression report less personal distress and fewer serious incidents.
What to Avoid
Arguing or correcting — Trying to reason with someone mid-outburst rarely works and often escalates the situation further.
Physical restraint as a first response — Restraints tend to increase fear and resistance; they should be reserved for genuine emergencies, not routine management.
Long-term antipsychotic use without reassessment, These medications carry a documented mortality risk in older adults with dementia and should be used at the lowest dose for the shortest time necessary.
Combative behavior warrants professional evaluation when it puts the person or others at immediate physical risk, when it appears suddenly without an obvious trigger, or when it’s paired with other new symptoms like fever, confusion beyond baseline, or sudden withdrawal. A sudden spike in aggression is often the first sign of an underlying medical problem, a urinary tract infection, dehydration, medication interaction, that needs prompt treatment.
Contact a doctor promptly if:
Aggressive episodes are increasing in frequency or intensity over a short period
The person injures themselves, a caregiver, or another resident
New symptoms accompany the aggression, such as fever, sudden confusion, or changes in mobility
Current medications don’t seem to be helping, or side effects seem worse than the behavior itself
The caregiver feels unsafe, overwhelmed, or unable to manage the situation alone
If you or someone else is in immediate physical danger, call 911 or your local emergency number. In the United States, the 988 Suicide and Crisis Lifeline (call or text 988) also supports caregivers and families in acute distress, not just people in psychiatric crisis. The National Institute on Aging offers additional guidance on managing dementia-related behavioral changes and connecting with local caregiver support resources.
