Behavior Changes of a Person with Dementia and How to Cope

Watching a loved one navigate life with dementia can feel like charting an unfamiliar and shifting landscape. The changes of a person with dementia go far beyond simple memory loss; they are profound shifts in perception, communication, and behavior that stem from physical changes in the brain. For family members and caregivers, these changes can be confusing, heartbreaking, and exhausting. However, by moving from a place of reaction to one of understanding, we can transform our approach from merely “managing symptoms” to providing compassionate, person-centered support. This guide explores the common behavioral shifts and offers practical, empathetic strategies for coping and maintaining connection.

The “Why” Behind the Behavior: It’s Communication, Not Choice

The first and most crucial step is reframing how we see these behavioral changes. A person with dementia is not being “difficult” on purpose. Their actions and reactions are often their primary way of communicating an unmet need, a feeling they can no longer articulate with words, or a response to a confusing world.

The brain changes caused by diseases like Alzheimer’s affect judgment, impulse control, and the processing of sensory information. What we see as a “behavior problem” is often a logical reaction from their perspective.

Common Behavioral Changes and Their Potential Meanings

1. Loss of Initiative or Apathy

What it looks like: Disinterest in hobbies, socializing, or even personal care. They may seem withdrawn or emotionally flat.
What it might mean: This isn’t laziness. It can be due to overwhelming anxiety about starting a task, depression, physical fatigue, or the brain’s diminishing ability to initiate complex sequences of actions.
How to support: Break activities into single, simple steps. Use gentle invitation instead of demand: “I’m going to fold these towels. Would you like to help me with this one?” Rather than expecting them to initiate, create opportunities for engagement through familiar sensory activities, like sorting objects or listening to beloved music.

2. Repetition (Questions, Stories, or Actions)

What it looks like: Asking “When are we going home?” every few minutes, or telling the same story on loop.
What it might mean: This behavior is a powerful source of comfort and security in a world that feels increasingly unfamiliar. It may express an underlying anxiety (like feeling unsafe), a need for reassurance, or the simple fact that short-term memory is no longer retaining the answer or the fact that the story was just told.
How to support: Practice infinite patience. Answer the question calmly as if for the first time. Often, addressing the potential emotion (“You seem like you’re wanting to feel safe. You are safe here with me.”) is more effective than the literal answer. Redirect to a calming activity like looking through a photo album.

3. Restlessness, Pacing, and Wandering

What it looks like: Inability to sit still, constant fidgeting, or walking aimlessly (sometimes with intent to “go to work” or “go home”).
What it might mean: This can signal physical needs (pain, hunger, thirst, needing the bathroom), excess energy, side effects of medication, or a deep-seated need from their past life (like a former daily routine). “Sundowning”—increased agitation in the late afternoon/evening—is also common.
How to support: Ensure basic needs are met first. Create a safe path for walking indoors. Introduce purposeful movement: “Can you help me walk to the mailbox?” or put on music for dancing. For those in need of structured support and companionship to mitigate these behaviors, engaging with a senior companion program in NW Washington, DC can provide essential social stimulation and supervision in a familiar environment.

4. Shadowing and Clinginess

What it looks like: Following a primary caregiver from room to room, becoming distressed when they are out of sight.
What it might mean: The caregiver represents safety in a frightening world. This behavior is rooted in anxiety and fear of abandonment. The person may have lost the ability to track time, so a two-minute absence can feel like hours.
How to support: Reassure verbally and with touch before leaving the room: “I am just going to the kitchen. I will be right back.” Leave something of yours with them as a placeholder. Use a baby monitor so you can reassure them with your voice from another room.

5. Sleep Disturbances and Night Walking

What it looks like: A reversed sleep-wake cycle, napping all day and being awake, confused, or active at night.
What it might mean: The brain’s internal clock (circadian rhythm) is damaged. It can also be due to lack of daytime stimulation/light exposure, discomfort, or the inability to distinguish dreams from reality.
How to support: Maximize daylight exposure and physical activity during the day. Establish a strict, calming bedtime routine. Avoid caffeine and large evening meals. Ensure the sleeping environment is safe to prevent injury if they do get up.

The Caregiver’s Toolkit: Strategies for Connection and Calm

Become a Detective, Not a Judge: Keep a simple log. Note what happened before, during, and after a challenging behavior. Look for patterns related to time of day, environment, or specific requests. Is the room too loud? Are they tired? Are you asking a question that requires complex reasoning they can no longer manage?
Change the Environment, Not the Person: Reduce clutter and noise. Ensure the home is well-lit to reduce shadows that can cause misinterpretations. Use clear signage on doors (like a picture of a toilet on the bathroom door).
Connect Through Feeling, Not Fact: Validation Therapy is key. Acknowledge the emotion behind the statement, rather than correcting the factual error. If they insist they need to see their mother (who is deceased), saying, “You must miss her very much. Tell me about your mother,” is more soothing than, “She passed away 30 years ago.”
Seek Professional Support Early: You do not have to navigate this alone. Sudden behavioral changes can indicate a urinary tract infection, pain, or other medical issues. A thorough check-up is essential. For ongoing, in-home support that blends expert care with compassionate companionship, families often find immense value in partnering with professionals like Capital City Nurses, who are trained in dementia-specific care techniques.
Care for Yourself to Care for Them: Your patience and resilience are finite resources. Respite care is not a luxury; it’s a necessity for sustainable caregiving. Seek support groups, ask family for help, and take time to recharge. A burned-out caregiver cannot provide calm, centered support.

Remember, the person within is still there, reachable through empathy, patience, and creative connection. The goal is not to control but to comfort; not to reorient to our reality, but to join them in theirs with love. By understanding the changes of a person with dementia as a form of communication, we open the door to more meaningful interactions, reducing distress for them and finding greater purpose in our role as caregivers.
