Caring for Residents With Dementia: A CNA's Guide
How to communicate, what to do when a resident is agitated, and how to handle sundowning, based on NIA and CMS guidance.
By the CaregiverCert team · Updated October 24, 2026 · 6 min read

Many nursing home residents live with Alzheimer’s disease or another dementia, and CNAs spend more time with them than any other staff. Federal rules require every CNA program to teach care of cognitively impaired residents, and nursing homes must include dementia training in your yearly in-service hours (42 CFR 483.95(g)). Here are the practical skills that make the biggest difference.
How to communicate
Tips from the National Institute on Aging (NIA) and the Alzheimer’s Association:
- Approach from the front, make eye contact, say the person’s name, and introduce yourself.
- Speak slowly and clearly in a warm, calm voice. Watch your face and body language too.
- Ask one question at a time, and give extra time to answer. Don’t interrupt.
- Offer simple choices (“Would you like the blue shirt or the red one?”) instead of open questions.
- Give step-by-step instructions and show what you mean.
- Don’t argue or correct. Arguing about facts usually makes things worse.
- Never talk about the person as if they aren’t there, and avoid baby talk.
- Use gentle touch, like guiding a hand, when it’s welcome.
As speech declines, nonverbal communication matters more. Some people who spoke two languages may go back to only their first language.
When a resident is agitated or aggressive
According to the NIA, agitation and aggression usually happen for a reason. Common causes include pain, too little sleep, constipation, medication effects, loneliness, too much noise, sudden changes in routine or caregivers, and being pushed to do something they can no longer do.
- Stay calm and patient. Use a soothing voice and reassure them they’re safe.
- Look for the cause, and tell the nurse about possible pain or a change in condition.
- Redirect to something pleasant, like a snack, music, or a short walk.
- Reduce noise and clutter.
- Protect yourself and others. Give space during an aggressive moment and get help.
Sundowning
Sundowning is restlessness, agitation, irritability, and confusion that starts as daylight fades. NIA suggests:
- Keep a consistent daily schedule.
- Encourage daylight exposure and physical activity during the day.
- Limit late-afternoon naps, and avoid caffeine late in the day.
- Keep evenings calm and well lit.
Why non-drug approaches matter
Since 2012, CMS has worked with nursing homes through the National Partnership to Improve Dementia Care to reduce unnecessary antipsychotic medications and increase person-centered, non-drug approaches. Many of those approaches depend on CNAs: consistent staff assignments, more exercise and time outdoors, watching for and reporting pain, and activities matched to each person.
Know your residents. Learning someone’s history, routines, and preferences is one of the most effective dementia care tools you have.
Frequently asked questions
How should a CNA respond to a resident with dementia who is confused?
Stay calm, don’t argue or correct, reassure them, and gently redirect. Use simple words and one question at a time.
What causes agitation in people with dementia?
Often pain, poor sleep, constipation, medications, noise, loneliness, or changes in routine. Report possible pain or sudden changes to the nurse.
What is sundowning?
Increased restlessness, confusion, or agitation in the late afternoon and evening. A steady routine, daytime light and activity, and a calm evening can help.
Do CNAs get dementia training?
Yes. Federal rules require CNA programs to cover care of cognitively impaired residents, and nursing homes must include dementia management in the at least 12 hours of yearly in-service training.
