Managing Dementia Behaviors: A Comprehensive Guide for Caregivers

At a Glance: This comprehensive guide helps family caregivers understand and manage common behaviors associated with dementia, including aggression, confusion, wandering, sundowning, and delusions. Learn proven strategies from the memory care experts at The Bristal.

Caring for a person living with Alzheimer’s or related forms of dementia presents unique challenges. As dementia progresses, the person in your care may display the various challenging behaviors dementia can bring, including confusion, aggression, delusions, wandering, and repetitive actions. These behavioral symptoms can be deeply exhausting for family caregivers to manage.

As the brain changes, a person living with dementia may struggle to communicate effectively. They may become confused, ask the same question repeatedly, make false accusations, or lash out. Understanding that these behavior changes are symptomatic of dementia—not from conscious choice—is vital for maintaining compassion and patience.

These behavioral symptoms often signal frustration, discomfort, fear, or an unmet need. Taking time to understand the reasons behind dementia behavior changes may help minimize occurrences, making time spent together more productive, successful, and enjoyable.

The Bristal offers specialized memory care for seniors living with Alzheimer’s and other types of dementia in our Reflections neighborhoods across the tri-state area. Our team members, trained in evidence-based memory care techniques, share practical tips to help caregivers manage common dementia behaviors with compassion and understanding.

Challenging Behaviors Caused by Dementia That Caregivers Typically Encounter

When caring for a senior living with dementia, it’s important to understand the nuances of challenging behaviors dementia presents to deliver truly compassionate and effective care. While these behaviors typically emerge in the middle to late stages of the illness, they can appear at different times for each individual.

Some of the most common challenges dementia caregivers face can also be some of the most difficult. Learning to manage dementia behaviors like confusion, aggression, delusions, wandering, sundowning, and repetitive actions requires time and patience.

Dementia Confusion

As dementia progresses, many people experience an inability to remember loved ones’ names and faces. Dementia confusion may express itself in questions like, “Who are you?”, “Why are you here?”, or “I want to go home!”

A person living with dementia may forget how to use everyday items, such as utensils or a pen. Or they may become confused about where they live, which is a concern if they experience wandering dementia and become lost.

The Alzheimer’s Association recommends specific strategies for effectively managing dementia confusion.

Do:

Remain calm and supportive
Stay proactive by introducing yourself and using visual cues
Focus on what they can do rather than what they cannot
Provide positive reinforcement throughout the day

Don’t:

Take their confusion personally
Attempt to make long, complicated explanations

People living with dementia sometimes second-guess themselves. One way to alleviate this stress is to focus on what they can do rather than what they cannot. Another way to assist a person experiencing confusion is to simplify tasks. Take complex tasks, such as ‘get dressed,’ and separate them into smaller, more manageable tasks, such as ‘put on socks.’

Confusion can also arise when a choice is too big or open-ended. Rather than asking what they would like to eat, offer two options from which they can choose.

Dementia Aggression and Agitation

People living with Alzheimer’s may become aggressive due to several factors. Dementia aggression can stem from overstimulation, confusion, physical pain, lack of sleep, or medication side effects, all of which can lead to physically or emotionally aggressive outbursts.

Sundowning—the increase in symptoms experienced by people living with dementia during late afternoon and evening—can intensify delusional thinking. As daylight fades and fatigue sets in, your loved one may become more convinced of false beliefs or experience heightened paranoia.

Dementia agitation often precedes aggression. When someone experiences agitation, they may become increasingly restless, anxious, or upset. This escalation from dementia agitation to dementia aggression happens when the person’s ability to process their surroundings and communicate what is happening becomes impaired.

For example, it may seem normal to have the television turned on and accompanying dinner conversation; however, it may be overwhelming for a person living with dementia, causing an outburst that may seem sudden. While aggressive behaviors like hitting, kicking, shouting, and crying are common and sometimes challenging to deal with, understanding that they are not personal can be beneficial.

Do:

Seek out the cause of what is triggering the aggression
Try to remove or reduce possible environmental stimulation like loud noises, bright lights, or alarms
Speak in a calm, lower tone and validate their distress
Pay attention to your body language—stand or sit to the side in a supportive stance

Don’t:

Try to restrain your loved one; instead, redirect their attention and avoid contact until they have calmed down
Lose your temper or put unnecessary pressure on them

Model the calm behavior you hope to encourage. While your loved one’s reactions are shaped by neurological changes, your steady presence helps to create a sense of safety and feelings of comfort.

Dementia Delusions, Paranoia, and Hallucinations

False accusations, suspicions about finances or fidelity, and other deeply distressing beliefs are common experiences for caregivers of people living with dementia. As cognitive decline progresses, changes in memory, perception, and reasoning can cause a person to misinterpret events or relationships, leading to accusations that feel sudden. While these behaviors can be emotionally challenging, they are a recognized symptom of dementia rather than a reflection of the individual’s true feelings or intentions.

It’s not uncommon for people with dementia to exhibit paranoid or delusional thinking or to experience hallucinations. Approximately 44 percent of people with dementia may develop dementia delusions at some stage of the illness, with the number potentially higher among certain groups.

When paranoia, dementia delusions, or hallucinations occur, it can be traumatic for caregivers—not only difficult to handle at a practical level but very hurtful emotionally. It can be particularly hurtful to have someone you are caring for make a false accusation toward you or another family member.

Understanding the Differences

Delusions are firmly held beliefs that are not real. Delusions can also be paranoid—examples would be believing someone is poisoning their food, or thinking someone is stealing their money. No amount of arguing or reasoning helps.

Hallucinations involve false perceptions of objects or events. When someone hallucinates, they may hear, see, smell, taste, or feel something that isn’t really there. Hallucinations are less common but can affect people with certain types of dementia.

Paranoia is an unrealistic concern that others are “out to get” the person or will harm them. A person living with dementia may develop a paranoid belief, like believing they’re being followed or believing someone is trying to harm them.

These symptoms tend to occur in mid-to-late-stage dementia. Dementia confusion and memory loss can contribute to these problems as the person struggles to make sense of their world. For example, if Mom can’t remember leaving her purse in the closet, she may accuse a family member of stealing it. If your husband doesn’t recognize a familiar caregiver, he may believe there’s a dangerous stranger in the house.

How Delusions Relate to Other Dementia Behaviors

Delusions rarely occur in isolation. Understanding how they interconnect with other challenging behaviors dementia brings can help you develop more effective management strategies.

When someone experiences dementia delusions, they often show signs of agitation—becoming increasingly restless, anxious, or upset. A false belief can trigger significant anxiety and result in agitation throughout the day, for example.

When to Consult a Doctor About Dementia Delusions

In rare cases, paranoia, dementia delusions, or hallucinations may have a reversible or treatable cause. Consider the possibility that the person may be experiencing delirium—a change in attention, awareness, or cognition that may persist for days or weeks.

Some medications can cause delusions or hallucinations. Drug interactions, or too much or too little of certain medications, can also affect a person’s mental and emotional stability.

If paranoia, dementia delusions, or hallucinations are new or if they can change in severity, discuss these possibilities with their doctor. Additionally, consult a physician if you believe delusions could lead them to harm themselves or a caregiver. While nondrug approaches should be tried first, medications may be appropriate in severe cases.

How to Manage Delusions and Accusations

Do:

Separate your own emotions of being accused from how you respond to the behavior
Validate that an object is missing and suggest looking for it together
Maintain a reassuring, predictable daily routine
Keep important items in view and provide reminders to minimize confusion
Offer opportunities to make choices and promote independence

Don’t:

Accuse your loved one of lying or manipulation
Get into heated, ongoing arguments about their accusations
Argue or try to convince with lengthy explanations

Additional Tips for Managing Dementia Delusions

Create a calm environment. Background noise from TV or radio can provoke fear or confusion. The line between reality and fantasy is often blurred in people with dementia. Reducing environmental stimulation is especially important during late afternoon and evening when sundowning tends to occur.
Offer simple answers. Don’t try to persuade with lengthy explanations. Complex explanations can increase confusion and frustration, potentially worsening the delusion.
Look for patterns. Does the behavior occur at a certain time of day? Keep a log of activities and look for ways to avoid triggers. Pay particular attention to whether delusions worsen during sundowning hours or after specific activities.
Distract and redirect. Switch the person’s focus to another activity. Ask them to help you with a chore or point out something of interest. This technique works well for many dementia behavior changes, including repetitive behaviors and agitation.
Keep extras on hand. If the person repeatedly loses and searches for a particular item, consider keeping several available. For example, if Dad loses his wallet and thinks it’s stolen, buy two or more of the same wallet.

Repetitive Behaviors

As your loved one’s condition progresses, you may notice them engaging in the repetitive behaviors dementia commonly brings. It might be saying the same word or phrase, or doing a task repeatedly. Experts believe the need for comfort, security, and familiarity drives this behavior.

While it is frustrating to answer the same question several times in a row or to witness your loved one repeatedly making their bed, try to remember they are attempting to make sense of their surroundings. In many cases, they may not recall having asked the question before or completed the task. These repetitive behaviors dementia causes are not intentional but rather a symptom of their condition.

Do:

Search for the cause of the repetitive behavior
Remain patient
Use activities to engage your loved one positively, such as household chores, singing, exercise, or gardening

Don’t:

React to how your loved one is behaving; instead, try to understand what they are feeling
Argue or try to use logic—if the behavior isn’t harmful, do your best to accept it

Wandering Dementia

Wandering is one of the most concerning behaviors for caregivers, as it poses serious safety risks. People living with dementia may wander for various reasons: searching for something familiar, following an old routine like “going to work,” feeling restless, or experiencing disorientation about their current location.

They might leave the house without telling anyone, get lost in familiar places, or seem driven to keep moving. This behavior can occur at any time of day but may worsen during periods of increased agitation or confusion.

Do:

Ensure your loved one wears an identification bracelet with emergency contact information
Install locks or alarms on doors, and consider motion sensors to alert you if they leave
Maintain a regular daily routine to reduce confusion and restlessness
Ensure your loved one gets adequate physical activity and exercise during the day
Consider enrolling in programs like MedicAlert + Alzheimer’s Association Safe Return

Don’t:

Leave your loved one alone if wandering has become a pattern
Assume they aren’t likely to wander, as wandering can start at any time.
Don’t prohibit them from moving about the room or physically restrict their movement, as pacing or cautiously contained wandering can be important and soothing.

If your loved one wanders off, stay calm and gently bring them back without scolding. Try to understand what triggered the wandering dementia episode. Were they looking for something? Feeling bored or anxious? Identifying the cause can help you prevent future incidents.

Sundowning Dementia

Sundowning dementia refers to a pattern of increased confusion, agitation, restlessness, and anxiety that occurs during late afternoon and evening hours. This phenomenon affects up to 20% of people with Alzheimer’s and can be one of the most exhausting and challenging behaviors dementia caregivers face.

During sundowning episodes, a person may pace, become argumentative, experience heightened dementia confusion, or show signs of aggression. They might insist on “going home” even when they are home, or become suspicious and fearful.

Experts believe sundowning dementia may be triggered by disruption to the body’s internal clock, fatigue from the day’s activities, reduced lighting that causes shadows and visual confusion, or overstimulation from the day’s events.

Do:

Maintain consistent daily routines with regular times for meals, activities, and bedtime
Ensure adequate lighting in the home before sunset to reduce shadows and visual confusion
Limit caffeine, sugar, and large meals in the afternoon and evening
Plan more demanding activities and appointments for earlier in the day when they are most alert

Don’t:

Allow long naps late in the day, as this can disrupt nighttime sleep
Schedule multiple activities or visitors during late afternoon hours

Creating a calm, predictable environment during the late afternoon and evening hours can significantly reduce sundowning symptoms. Consider playing soothing music, utilizing lighting timers, closing curtains to reduce glare, and engaging them in quiet, familiar activities during this time.

Frequently Asked Questions About Dementia Behaviors

When do dementia behavior changes typically begin?

Behavior changes often emerge in the middle stages of the illness, though the timing varies for each individual. Early signs may include mild confusion or mood changes, while more challenging behaviors dementia brings—like wandering, aggression, and sundowning—typically appear as the illness progresses.

Are delusions in dementia the same as lying?

No. Dementia delusions are not lies. Your loved one genuinely believes what they’re saying is true. Their brain is misinterpreting reality due to changes caused by dementia. These false beliefs are a symptom of the illness, not intentional deception.

Can medication help with dementia delusions?

While non-drug approaches should always be tried first, medications may be prescribed in severe cases where delusions lead to significant distress or safety concerns. Always consult with your loved one’s physician before starting any new medications, as some can worsen confusion or cause other side effects.

Do delusions get worse as dementia progresses?

Delusions typically appear in mid-to-late stage dementia and may fluctuate in intensity. Some people experience periods where dementia delusions are more frequent or intense, while at other times they may diminish. Tracking patterns can help you prepare for and manage these challenging behaviors.

What causes sundowning in dementia?

Sundowning is believed to be caused by disruptions to the brain’s internal clock, end-of-day fatigue, reduced lighting that creates visual confusion, and the accumulation of stimulation throughout the day. Maintaining consistent routines and ensuring proper lighting can help minimize sundowning symptoms.

How are delusions different from sundowning?

While sundowning refers to increased confusion and dementia agitation during late afternoon and evening, delusions are specific false beliefs that can occur at any time of day. However, delusions may become more pronounced during sundowning hours due to increased fatigue and confusion.

Should I correct my loved one when they have dementia delusions?

Generally, no. Correcting or arguing about delusions typically increases agitation and distress without resolving the false belief. Instead, acknowledge their feelings, offer reassurance, and gently redirect their attention.

How can I prevent wandering behaviors in dementia?

While you cannot completely prevent wandering, you can reduce risks by maintaining regular routines, ensuring adequate physical activity, installing door alarms, and addressing underlying causes such as boredom, discomfort, or the need to use the bathroom.

Are repetitive behaviors displayed by seniors with dementia harmful?

Most repetitive behaviors exhibited by seniors living with dementia are not dangerous and often provide comfort. Unless the behavior poses a safety risk or significantly disrupts daily life, it’s often best to accept it rather than try to stop it.

What is the difference between dementia agitation and dementia aggression?

Agitation refers to restlessness, pacing, and increased anxiety, while aggression involves more intense behaviors like hitting, kicking, or verbal outbursts. Both are responses to unmet needs, overstimulation, or confusion rather than intentional actions.

When to Seek Professional Memory Care Support

Caring for a person living with dementia can be difficult and take a toll on the physical and mental health of the caregiver. Experiencing feelings of resentment, depression, or fatigue is common. Caring for yourself is essential. You can get support by reaching out to a counselor, friend, or family member.

These experiences—from paranoia and hallucinations to wandering, aggression, and sundowning—can be deeply exhausting, and that’s completely understandable. Don’t feel alone. Join a support group or find an online forum where you can share and discuss your experiences with others who are going through the same thing.

While there is currently no cure for Alzheimer’s or dementia, memory care programs, therapies, and medications are available to help you support and manage your loved one’s care. Work with a medical professional to explore these options as their needs change over time.

If you’re finding it increasingly difficult to manage dementia-related behaviors, it may be time to consider professional memory care. When behaviors like wandering, severe aggression, or intense sundowning become difficult to manage safely at home, specialized memory care options can provide the support your family needs.

Professional memory care communities like The Bristal offer 24-hour supervision, secure environments to prevent wandering, and team members trained to support people living with dementia with compassion and expertise. At The Bristal, our Reflections neighborhoods throughout the tri-state area offer a specialized memory care team that understands the complexities of supporting individuals through the behavioral and cognitive changes that come with dementia.

Learning to delegate is important. Ask a friend or family member for assistance. People may think you are doing a great job and do not need help. Join a support group in your area—many are now offered virtually, making it easy to meet from the comfort of your own home.
