Understanding the Complex Emotions Surrounding Dementia Care
Dementia becomes a “love-hate” dynamic because the disease destroys a person’s emotional and cognitive regulation while leaving their core human need for affection intact. This creates a heartbreaking paradox where loved ones and patients feel deep love for one another, yet mutually experience intense frustration, exhaustion, and moments of resentment. [1, 2, 3, 4, 5]

The “Hate”: Why Patients and Caregivers Experience Frustration

Behavioral Shifts: Dementia physically alters the brain, removing the filters that control impulses and emotions. Patients may lash out, become paranoid, or say hurtful things they would never otherwise express. [1, 2, 3, 4]
Fear and Disorientation: Because patients lose their short-term memory and ability to process their environment, everyday assistance can feel threatening or controlling to them. Their anger is typically a coping mechanism or an attempt to communicate physical pain or confusion. [1, 2]
Caregiver Burnout: For family members, constantly being on high alert, receiving hostility, and mourning the gradual loss of their loved one’s personality can lead to profound exhaustion and moments of resentment. [1, 2]

The “Love”: The Enduring Connection

Need for Affection Remains: Alzheimer’s and other dementias do not erase a person’s desire for connection and warmth. Moments of lucidity often reveal the deep, unchanged affection a patient has for their family. [1, 2]
Caregiving as an Act of Love: Despite the emotional toll, caregivers are driven by love to protect, comfort, and advocate for their relatives. [1, 2, 3, 4]
Separating the Disease: Managing this dynamic involves realizing the “mean” behavior is a symptom of the disease, not a reflection of the patient’s true feelings or personality. [1, 2]

Finding support through groups can help navigate these intense, conflicting emotions. You can connect with others walking a similar path by visiting the Alzheimer’s Association or joining community discussions on the Alzheimer’s Society Forum. [1, 2]

Can Dementia Cause ‘Mean’ Behavior?

Key Takeaways

Behaviors that may seem mean — such as snapping at loved ones, doubting intentions, or saying hurtful things — are often manifestations of dementia rather than a person’s true feelings or choices.
As people with dementia experience greater memory loss and disorientation, they are likely to feel fearful and frustrated and may express these feelings through aggressive behavior. Dementia can also affect a person’s ability to regulate emotional responses.
You can help manage these behaviors by making everyday adjustments (like using a handheld shower nozzle), keeping routines consistent, moving slowly and calmly, and working with a healthcare professional to consider appropriate medications or therapies.

What Is Dementia? And How To Care For Someone Who Has It by Marjorie Harder

Dementia is a category of medical conditions involving symptoms such as memory loss, decreased cognitive performance, and diminished reasoning ability. Alzheimer’s disease is the number one cause of dementia.

While dementia is often associated with growing older, it isn’t considered a part of natural aging.

Symptoms of dementia result from brain cell damage. As communication between neurons decreases, a person may begin to behave differently than they used to, including in ways that may be perceived as mean.

Can dementia cause someone to become mean?

Dementia can involve changes in thoughts and behaviors, including some behaviors that may seem to indicate meanness. Someone with dementia may suddenly seem like they don’t care about your feelings. They may snap at you, doubt your intentions, resist your efforts to help them, or say hurtful things.

These behaviors are often manifestations of dementia rather than indications of a person’s true feelings or choices. This type of behavior is associated with dementia symptoms such as:

agitation
aggression
disinhibition
depressed mood
anxiety
sleep disturbance
psychosis

As many as 90%Trusted Source of people with Alzheimer’s disease experience behavioral symptoms such as agitation and irritability. But not everyone living with dementia will display so-called mean behaviors.

In a 2021 review, researchers indicated that agitation (which included symptoms of aggressiveness, restlessness, and emotional distress) had an overall prevalence of 30% across all types of dementia, with the highest prevalence (up to 50%) occurring in Alzheimer’s disease.

Dementia symptoms can show up differently depending on which areas of the brain are affected by cellular change.

Dementia and altered thinking skills

Seemingly mean and aggressive behaviors, including those directed toward family members, are often due to changes in thinking that are associated with neurodegeneration — a decrease in cellular health and function in the central nervous system.

A 2021 study suggests that late-life cynical hostility — a type of meanness that involves a mistrust of others — is linked to white matter changes in the brain that may be early indicators of Alzheimer’s disease.

“The more the cortex is sludged with plaques and tangles like in Alzheimer’s disease, the more it fails to inhibit,” explained Dr. Sudhir Gadh, a board certified psychiatrist from New York City. “Underlying impulses are no longer controlled, patience is lost, memories are lost, abilities diminish, and anger can reign.”

The complexity of altered thinking in dementia can mean that minor frustrations turn into aggressive outbursts and that other intense emotions, such as fear and confusion, show up as combativeness.

Someone with dementia may experience more anxiety, agitation, and confusion if they don’t understand their circumstances because of memory loss.

How to manage mean behaviors in dementia

Caring for someone with dementia who is experiencing personality changes and being mean to their family can be challenging. You may feel that you’ve lost the loving bond you once had with that person.

While progressive dementia, such as the type associated with Alzheimer’s disease, has no cure, it’s possible to manage the symptoms and decrease the occurrence of mean behavior.

Identify everyday life adjustments

What may be comforting or natural for you may be a source of frustration for someone who is living with dementia.

Dr. Donna Seminara, director of the division of geriatrics at Staten Island University Hospital, New York, says mean-spirited behaviors are often the only way that some people with dementia can express frustration. For example, a person with dementia may say something hurtful or become physically combative when you’re helping them take a bath.

“What is often relaxing to most — having warm water trickle from the head and face down the body — is often agitating to […] individuals who can’t control the flow of water,” she said. “Using a handheld shower nozzle where the patient can exert some control may make this experience much less stressful for all.”

Establish a stable, consistent environment

Seminara pointed out that bringing someone with dementia into new environments can have complicated outcomes, such as fear, confusion, and memory loss.

By keeping routines and environments as consistent as possible, you can promote a sense of familiarity and comfort that can reduce aggressiveness and mean behaviors.

Medical perspective

“Consistency in routine can help decrease certain aggressive or ‘mean’ behavior, as well as not reacting emotionally in the moment if offensive things are said or done.”

Take the slow approach

Abrupt movements may be disconcerting to someone living with dementia.

“Try to maintain a positive, smiling face toward the patient, and always touch the patient with a slow approach. Fast, sudden movements are startling to most dementia patients and can start a cascade of resistant speech and behavior,” explained Seminara.

Consider appropriate medications

Medications may help manage some of the behavioral symptoms of dementia.

“There are several treatments for the depression and anxiety associated with dementia, assuming a treatable medical condition has been ruled out, including psychotherapy, antidepressants, antianxiety agents, and the nutritional support of the B vitamins folate and B12,” said Dr. Sheldon Zablow, a board certified psychiatrist from San Diego.

Gadh pointed out that prevention is paramount and should be considered a form of dementia treatment. This is particularly the case because there’s no specific treatment for dementia that has remarkable results and a low side effect risk.

An emerging treatment option for dementia, low dose lithium, may fill that treatment gap one day. Gadh explained that lithium, a natural salt, has been associated with improved mental health and decreased dementia risk.

Lithium is currently used to treat bipolar disorder.

“It is already being studied by the National Institutes of Health for the prevention of Alzheimer’s because lithium is a known neurotrophic (enhancer of brain growth via GSK-3 inhibition),” he added.

Supporting a loved one with dementia

A focus on the hallmarks of dignity, respect, and choice can help you support a loved one who is living with dementia.

Regardless of their level of cognitive function, people with dementia want to be treated humanely. By keeping this in mind, you may be able to better manage or limit their behavioral symptoms.

According to a review published in 2018Trusted Source, some of the best practices for supporting someone with dementia are:

recognizing how much support they need in areas of daily functioning, such as dressing, eating, and using the bathroom
tailoring their care to their abilities, likes, and dislikes
giving them opportunities to make simple choices, such as when dressing or eating
upholding their dignity and respect during vulnerable or private moments, such as when they are using the bathroom
being aware of their comfort at all times, particularly in relation to incontinence, dental health, and personal hygiene
creating a quiet, comfortable, and home-like atmosphere
considering cultural practices, such as those associated with mealtime

It can be challenging to determine how best to support your loved one and maintain their dignity. You may find professional guidance helpful for learning strategies to keep private moments, such as bathing and using the toilet, safe and respectful.

Medical perspective

“It can be very difficult to manage your own emotions when your loved one has behavior that can come across as offensive or ‘mean.’ It is important to understand that increased aggression can be due to dementia affecting certain areas of the brain, which disinhibits different emotions. They may be completely unaware of their behavior, and they also may not be able to control it.”

REMEMBER ME:

We went through something very similar, and my heart goes out to you.

Looking for assisted living or memory care from a distance can feel overwhelming, especially when you’re trying to plan ahead and make the best decision for everyone involved. I remember spending hours reading reviews, talking to families, and wondering whether a community would truly provide the level of care and compassion our loved one needed. It can be stressful because what looks great on paper doesn’t always match the day-to-day experience. You’re definitely not alone in feeling this way.

Another caregiver mentioned Love That Stays Soft: Everyday Dementia Caregiving and What Really Helps: Jackson, Dr. Anderson: 9798249070823: Amazon.com: Books to me during a particularly difficult time. I didn’t rush out to get it because I already felt overwhelmed with information and advice. But after seeing it recommended a few more times, I finally picked it up. The chapters on care transitions, evaluating facilities, and balancing a loved one’s needs with family realities really resonated with me and helped me understand what was happening in a different way.

One thing that helped us was joining local Florida caregiver groups and asking families for recent firsthand experiences rather than relying only on online ratings. If you already know the area you’re considering, you may get specific recommendations from local caregivers. Be gentle with yourself through this process. You’re doing the best you can in a very difficult situation. make sure to get the book on Amazon it helped me a lot during that stage.

Bottom line

You may feel that a loved one with dementia has started being mean to you and others. But these new behaviors do not likely indicate that the person has negative feelings toward you. Instead, this behavior is likely a manifestation of other symptoms of dementia.

As people with dementia experience greater memory loss and disorientation, they are likely to feel fearful and frustrated and may express these feelings through aggressive behavior. Dementia can also affect a person’s ability to regulate emotional responses.

While there’s no cure for progressive forms of dementia, professional treatments may help. As a caregiver, you can support someone with dementia by focusing on consistency, freedom of choice, and humane treatment.

RANT: Too many people (including professionals) think people with severe dementia are the same as young children!
