One of the most common things I hear from family caregivers is:
“Mom is becoming so difficult.”
Or…
“Dad is doing this on purpose.”
The truth is, people living with dementia are not trying to be difficult—they are having a difficult time.
What we often call “behaviors” are actually forms of communication. As dementia changes the brain, words become harder to find, reasoning becomes more difficult, and the ability to explain needs begins to fade. Instead, the brain communicates through actions.
When we learn to identify what is driving a behavior, we can often reduce distress before it escalates.
Here are five of the most common dementia behavior triggers I see when working with families.
1. Feeling Rushed
Imagine trying to complete a puzzle while someone stands behind you saying, “Come on… hurry up!”
That’s often what everyday life feels like for someone living with dementia.
The brain processes information more slowly. Extra time is needed to understand what is being asked, organize a response, and complete a task.
Instead, try:
- Slow your pace.
- Ask one question at a time.
- Give plenty of time for a response.
- Avoid finishing sentences unless asked for help.
- Focus on the process, not the schedule.
Sometimes slowing down by two minutes prevents a thirty-minute struggle.
2. Too Much Stimulation
Busy restaurants.
Television playing in the background.
Several people talking at once.
Bright lights.
Strong smells.
What feels like a normal environment to us can feel overwhelming to a brain living with dementia.
When too much information is coming in at once, the brain may respond with anxiety, irritability, withdrawal, or agitation.
Instead, try:
- Reduce background noise.
- Turn off the television during conversations.
- Speak one at a time.
- Choose calm, familiar environments whenever possible.
- Watch for signs of sensory overload.
Sometimes less stimulation creates more connection.
3. Physical Discomfort
People living with dementia may no longer be able to tell you they are in pain.
Instead, pain, hunger, thirst, constipation, infection, fatigue, or needing the bathroom may appear as:
- Restlessness
- Pacing
- Calling out
- Refusing care
- Aggression
- Increased confusion
Instead, ask yourself:
- Could they be hungry?
- Are they thirsty?
- Do they need the restroom?
- Could they be in pain?
- Are they tired?
- Have there been any recent medical changes?
Always rule out physical causes before assuming the behavior is caused by dementia alone.
4. Being Corrected or Argued With
As dementia progresses, logic becomes less reliable.
Trying to convince someone they are wrong often increases frustration for everyone involved.
When we insist on facts, the person may feel embarrassed, scared, or misunderstood—even if our intention is to help.
Instead, try:
- Validate the emotion before addressing the situation.
- Join their reality rather than forcing yours.
- Redirect gently.
- Focus on how they feel, not whether they are factually correct.
Remember:
You can win the argument, or you can preserve the relationship—but it is difficult to do both.
5. Lack of Purpose and Engagement
Every person needs purpose.
Without meaningful activity, boredom can quickly become anxiety, wandering, repetitive questions, or searching for something to do.
Many behaviors decrease when people are engaged in activities that match their remaining abilities.
Instead, offer:
- Folding towels
- Watering plants
- Looking through family photos
- Listening to favorite music
- Sorting objects
- Baking together
- Gardening
- Walking
- Simple household tasks
Meaningful engagement doesn’t have to be elaborate.
It simply has to be meaningful to the individual.
The Most Important Question
The next time a behavior occurs, instead of asking:
“How do I stop this behavior?”
Try asking:
“What is this person trying to tell me?”
That one question changes everything.
It shifts our focus from managing behaviors to understanding unmet needs.
When we respond with curiosity instead of frustration, we create opportunities for connection, comfort, and trust.
Remember…
Every behavior has a reason.
Sometimes the reason is physical.
Sometimes it is emotional.
Sometimes it is environmental.
And sometimes it is simply the brain doing the best it can with the changes it is experiencing.
The behavior is rarely the problem.
The unmet need usually is.
