Sundowning is a late-day worsening of confusion, anxiety, agitation, or sleeplessness in a person with dementia. Families should address wandering, falls, unsafe driving or stove use, aggression, and access to medicines or weapons. Sundowning is a caregiving safety concern, not a separate dementia diagnosis, according to MedlinePlus. A practical response combines medical assessment, predictable routines, safer surroundings, and a plan for a missing person.

Recognize the pattern—and a change that needs attention
Sundowning may appear as restlessness, pacing, lost sleep, or aggressive behavior that starts or worsens in late afternoon or early evening. track when the behavior begins, what happens beforehand, and whether it represents a new pattern. Do not assume every late-day change is an inevitable part of dementia.
The National Institute on Aging advises seeking a clinician's assessment for new or worsening agitation. Pain, depression, stress, constipation, medication effects or interactions, and sudden changes in routine or surroundings may contribute. The distinction matters because securing doors will not resolve pain or a medication problem. Share the timing, symptoms, recent changes, and medication information with the clinician.
Reduce predictable late-day triggers
Build the day around a consistent schedule. Daytime sunlight and activity may reduce late-day restlessness, while long naps late in the day can interfere with nighttime sleep.
Review the hours before symptoms usually begin: These steps may lower risk, but they cannot guarantee that sundowning or wandering will stop. Keep safety measures in place even when a routine appears to help.
- Schedule needed activities and supervision around the person's usual restless or wandering period.
- Make sure basic needs are met.
- Limit late-day caffeine and alcohol.
- Avoid long late-day naps.
- Reduce abrupt changes in routine or surroundings.
Prepare for wandering before it happens
Everyone with dementia is at risk of wandering, and six in 10 will wander at least once, according to the Alzheimer's Association. Some people wander repeatedly, making preparation important even without a previous incident. Door alarms and pressure mats can alert a caregiver when someone approaches an exit or gets out of bed.
Night-lights can make routes easier to see, while gates can limit access to stairs and exits. Never lock a person inside the home. Remove access to car keys when driving is no longer safe. Do not leave a confused person unsupervised in an unfamiliar setting, and plan closer supervision during the hours when wandering usually occurs.
Make nighttime hazards harder to reach
Dementia can impair judgment, balance, and perception, turning ordinary nighttime obstacles into serious hazards. Improve lighting along routes to the bathroom, bedroom, stairs, and exits, and remove items that could cause a fall. The Alzheimer's Association home-safety guidance also recommends securing medicines and weapons.
Prevent unsafe stove use with shutoffs or knob controls. Look at the home from the perspective of someone who is confused and awake after dark. A poorly lit step, accessible medicine bottle, available car key, or working stove knob may require a specific safeguard.
Have a missing-person response ready
If the person disappears, begin searching immediately. Check the nearby area and places the person visited in the past rather than waiting to see whether they return.
If the person is not found within 15 minutes, call 911. Many missing people with dementia are found within 1.5 miles, so the nearby search should begin at once while the emergency response is activated.
