Preventing Difficult Behaviors During Activities: A Guide for Caregivers at Home

When a person living with dementia becomes agitated, refuses care, or wanders during an activity, it is often their way of communicating an unmet need or feeling overwhelmed. This guide helps you understand why these behaviors happen and gives you concrete, step-by-step strategies to prevent them before they start. You will learn how to set up the environment, choose the right activities, and respond calmly when things get tricky. With a few adjustments, you can turn stressful moments into more peaceful, connected time together.

Key points

  • Difficult behaviors are communication—look for the unmet need behind the behavior.
  • Prevention is more effective than reaction: identify triggers and change the environment or activity.
  • Use distraction and redirection early, before the behavior escalates.
  • Keep activities simple, short, and matched to their current ability.
  • Stay flexible: what works today may not work tomorrow; be willing to try a new approach.
  • Never confront, argue, or initiate physical contact during an outburst—prioritize safety and calm.

Why Difficult Behaviors Happen During Activities

Difficult behaviors like agitation, wandering, or refusing care are not deliberate misbehavior. They are a form of communication. The person with dementia is trying to tell you something—maybe they are confused, tired, hungry, in pain, or overstimulated. Their brain is struggling to process what is happening, and the behavior is their best attempt to cope in that moment. As one expert explains, these behaviors are 'a form of communication' and we need to be 'the detective' to figure out what need is not being met (source 18).

Common triggers include: a task that is too hard or has too many steps, a noisy or cluttered environment, a time of day when they are more confused (like late afternoon or evening, known as sundowning), or even something as simple as needing to use the bathroom. For example, a person may wander or try to leave the house because they feel lost or anxious, especially during sundowning when confusion and heightened behaviors often occur (source 1, 3, 4). By understanding these triggers, you can change the activity or the setting to prevent the behavior from happening in the first place.

The Power of Prevention: Setting the Stage for Success

Prevention is far more effective than trying to manage a behavior after it has started. The key is to identify what happens right before the behavior—the 'antecedent' or trigger—and then change that trigger. This is called a behavioral modification approach: you look at what is happening before, during, and after the behavior, and then create a plan to reduce or avoid the circumstances that lead to it (source 20).

For example, if the person becomes agitated every time you try to help them dress, the trigger might be that the task has too many steps or that they feel embarrassed. You can prevent the agitation by simplifying the task (laying out clothes in order), using a fun distraction like singing a silly song, or giving them more time and privacy (source 6). Similarly, if wandering happens around 4 p.m. every day, you can schedule a calming activity—like looking at a photo album or going for a short walk—just before that time to keep their brain focused and reduce the urge to wander (source 14).

The Role of Environment and Routine

The physical environment and daily routine play a huge role in preventing difficult behaviors. A calm, predictable environment helps the person feel safe and reduces confusion. Simple changes can make a big difference: reducing noise and bright lights at night can improve sleep and reduce daytime agitation (source 11). During activities, make sure the space is quiet, well-lit, and free from clutter. Remove items that might cause confusion or distress, like mirrors that can startle someone who doesn't recognize their own reflection (source 5).

Routine is also powerful. Doing the same activities at the same time each day helps the person know what to expect, which lowers anxiety. But remember: what works today may not work tomorrow. Stay flexible and be willing to try a different approach if the current one stops working (source 26). The goal is not to eliminate all behaviors, but to reduce them and make daily life more manageable for both of you.

Step-by-step

  1. Keep a simple behavior log for a few days: write down what happened right before the behavior, what it looked like, the time, who was there, and what helped afterward—patterns will tell you what to change.

  2. Match the activity to their current ability and break it into one or two steps: hand one item of clothing at a time instead of saying 'get dressed,' and use hand-under-hand guidance for tasks like brushing teeth.

  3. Watch for early warning signs of agitation—pacing, fidgeting, a shift in tone—and redirect before things escalate: put on familiar music, offer a snack, or pull out a photo album.

  4. Time activities to their best moments of the day: if sundowning tends to hit around 4 p.m., begin a calming activity by 3:30 p.m.—cooking together or listening to music.

  5. Set up a calm environment for every activity: reduce background noise, soften harsh lighting, clear clutter; if wandering is a risk, disguise doors with curtains or a STOP sign and keep coats, keys, and shoes out of sight.

  6. Offer simple, genuine choices—'Would you like the photo album or some music?'—and if they refuse an activity, try again later with a different approach.

  7. Speak in a calm, warm, slow tone; never argue, correct, or criticize; validate the feeling and gently redirect.

  8. When agitation happens, pause and give both of you a time out—step away for a few minutes, then return with a fresh approach—and never grab, pull, or initiate physical contact during an outburst.

  9. Check that basic needs are met before starting: hunger, thirst, bathroom, and pain; scheduled toileting and keeping water and a snack within reach prevent distress.

  10. Choose activities that connect to their life story—someone who loved gardening will often light up at sorting seeds or watering a plant.

What not to do

  • Do not argue, correct, or try to reason them out of their reality; validate the feeling and redirect.

  • Do not grab, pull, or physically restrain during an outburst—step back, give space, and try again later.

  • Do not push through a sundowning episode by scheduling stimulating activities late in the day; plan a calming alternative about 30 minutes before it usually starts.

  • Do not expect yesterday's success to repeat today—stay flexible and change your approach without blaming yourself or them.

  • Do not take behavior personally and avoid 'elderspeak'—the sing-song, simplified, baby-talk tone that condescends and backfires.

Practical tools

  • The Behavior Log

    A notebook or phone note for each difficult behavior: date, time, what happened just before, what the behavior looked like, who was there, and what you tried. After a few days, look for patterns—a time of day, a person, a task. Those patterns become your prevention checklist.

  • The One-Step-at-a-Time Script

    Write any multi-step task (dressing, brushing teeth) and break it into the smallest steps. Write the simple phrase you will use for each—'Here is your shirt, let's put your arm through.' Keep it where you can glance at it. It prevents rushing and gives you words when your mind goes blank.

  • The 'What Works for [Name]' Profile

    A one-page cheat sheet you fill out as you learn: favorite music, beloved hobbies, foods they love, topics that bring a smile, things that reliably trigger distress (loud TV, being rushed), and redirection tricks that have worked. Pin it inside a cabinet door or save it on your phone. It helps any caregiver stay personal when you are exhausted.

Discuss with your clinician

If the person's agitation or aggression becomes frequent, severe, or dangerous (e.g., hitting, throwing objects), discuss with their doctor whether a medication evaluation is needed. Do not start or stop any medications without medical guidance.

If you notice sudden changes in behavior, such as new hallucinations, extreme confusion, or physical symptoms like fever or pain, contact their clinician immediately. These could signal a medical issue like an infection or medication side effect.

If you are considering using any over-the-counter supplements or herbal remedies to help with sleep or mood, talk to the doctor first, as they can interact with other medications or worsen symptoms.

If the person has a history of falls or is at high risk for falls, discuss with their doctor or physical therapist how to safely adapt activities to prevent injury.
