Sundowning in Memory Care: What Good Communities Do Differently

Quick answer: Sundowning is increased confusion, restlessness, anxiety or agitation in people with dementia during the late afternoon and evening. Good sundowning memory care plans for those hours with extra staff, calm lighting, predictable routines, meaningful activity, and individualized calming strategies rather than relying on medication. Families should ask how a community staffs and structures the 3 p.m. to 9 p.m. window.

For many families, sundowning is what finally makes caregiving at home impossible. A parent who is pleasant in the morning becomes anxious, insists on going “home,” paces, or becomes upset as daylight fades, and the family caregiver is exhausted by dinnertime. Sundowning in memory care is common, but how communities respond to it varies widely. This guide explains what sundowning is, what causes it, how families can reduce it, what good sundowning memory care looks like, and the questions to ask when choosing a community.

What is sundowning?

Sundowning, sometimes called sundown syndrome, is a pattern of increased confusion and behavioral symptoms that begins in the late afternoon or early evening and can continue into the night. It is most common in middle and later stages of Alzheimer’s disease and other dementias.

Common signs of sundowning include:

• Restlessness, pacing or wandering
• Anxiety, fear or tearfulness
• Asking to go home, even when at home
• Suspicion or accusations
• Agitation, yelling or resisting care
• Difficulty sleeping or nighttime waking
• Seeing or hearing things that are not there

What causes sundowning in dementia?

The exact cause is not fully understood, but several factors often contribute:

• Fatigue at the end of the day
• Changes in light, including shadows and dimness that make the environment confusing
• Disrupted internal body clock, common in dementia
• Overstimulation, such as shift changes, noise, or busy dinner rooms
• Unmet needs, including hunger, thirst, pain, a full bladder, or constipation
• Medication timing or side effects
• Infections, such as a urinary tract infection, which can cause sudden worsening

A sudden increase in sundowning should always prompt a medical check, because infections and pain are common, treatable causes.

How can families reduce sundowning at home?

• Keep a consistent daily routine for waking, meals, activities and bedtime.
• Encourage daylight exposure and activity earlier in the day.
• Limit caffeine and sugar in the afternoon.
• Turn on lights before dusk and close blinds to reduce shadows.
• Offer a calm, familiar activity in late afternoon, like music, folding towels, or looking at photos.
• Avoid arguing or correcting. Acknowledge feelings and gently redirect.
• Keep evenings quiet, with fewer visitors and less noise.

What does good sundowning memory care look like?

The best memory care communities treat late afternoon as a planned part of the day, not a problem to react to. Look for:

• Staffing that matches the need: enough caregivers on the floor in late afternoon and evening, and shift changes that do not disrupt residents.
• Structured late-day programming: calm activities from about 3 p.m. on, such as music, walks, snacks, hand massage, or simple tasks.
• Lighting design: bright, even lighting that comes on before dusk and reduces shadows.
• Quiet dining: smaller dining groups or a calm dining room.
• Individualized care plans: written notes on each resident’s triggers, history and calming strategies.
• Safe walking paths: secure indoor and outdoor areas where residents can pace safely.
• A non-drug first approach: staff trained to address unmet needs and redirect before considering medication.

Our overview of memory care facilities in San Diego and our guide to board and care homes for dementia explain the differences between large communities and small homes, which often handle sundowning differently.

Are board and care homes good for sundowning?

Often, yes. A board and care home with six residents or fewer can be quieter and calmer in the evening, with consistent caregivers who know each resident well. That familiarity helps staff spot early signs of agitation. The tradeoff is fewer structured group activities and, in some homes, less secure outdoor space. Our comparison of board and care homes vs large communities in San Diego covers these differences.

What questions should you ask about sundowning on a memory care tour?

• How many caregivers are on duty from 3 p.m. to 9 p.m., and overnight?
• When do shifts change, and how do you keep that time calm?
• What activities do you offer in the late afternoon?
• How do staff respond when a resident insists on going home?
• How do you learn each resident’s calming strategies?
• When would you call the doctor about worsening sundowning?
• What is your approach to medications for agitation?

Visit in the late afternoon, not just the morning, to see how the community handles that time. Our post 14 memory care tour red flags lists other things to watch for, and questions to ask the memory care executive director adds more.

How can families help a parent with sundowning settle into memory care?

• Write a one-page profile with your parent’s routine, triggers, comforting objects, music, and phrases that help.
• Schedule visits earlier in the day at first, if evening visits trigger requests to leave.
• Bring familiar items that feel like home.
• Ask for a care conference after two to four weeks to review how evenings are going.
