Daytime wandering is a genuine dementia safety risk; daylight and familiar surroundings do not make an unsupervised outing reliably safe. Wandering means movement that can take someone away from a safe, expected setting when they cannot orient themselves or return. The risk is not limited to late-stage dementia or a particular time of day. The Alzheimer's Association wandering guidance says wandering can occur at any stage and estimates that six in 10 people with dementia will wander at least once, often repeatedly.

Why daylight does not remove the danger
dementia can affect memory, attention, judgment, visual processing, and recognition. The CDC identifies getting lost in a familiar neighborhood as a warning sign, so a well-known daytime route may no longer be reliably familiar. A routine walk can become dangerous after a wrong turn, a change in the surroundings, or confusion about place and time.
"Critical wandering" describes leaving a home or facility alone while unaware of place or time. It can result in serious injury or death, especially when the person remains missing for 24 hours. A 2024 Alzheimer's & Dementia study found recent critical wandering in 3% of more than 1.5 million Canadian long-stay home-care clients. That figure applies to this specific population and recent, critical events—not to everyone with dementia or every form of wandering.
Which warning signs call for a safety plan?
Families should focus on changes in the person's behavior and navigation, rather than assuming an outing is safe because it happens during the day. Warning signs include: These signs cannot predict exactly when someone will leave or become lost.
They do show that the family should review supervision, transportation, door security, identification, and emergency plans before an incident occurs. Consider whether the person can recognize the route, manage an unexpected detour, return at the expected time, and seek help. A previously successful walk does not guarantee that the next one will be safe.
- Returning unusually late from a regular walk or drive
- Forgetting a familiar route
- Repeatedly saying they need to "go home"
- Pacing or moving restlessly
- Becoming lost when surroundings change
How can families reduce the risk?
No single precaution eliminates wandering. Families can combine daily routines, supervision, identification, and home safeguards: These layers serve different purposes.
Activity may reduce an unmet need, an alarm can signal a departure, and identification or GPS may help locate someone who has already left. The National Institute on Aging's wandering guidance says people with a history of wandering should not be left unattended. Walking can still be part of the day, but the level of accompaniment should match the person's current ability to stay oriented.
- Schedule meaningful activity during periods when wandering is more likely.
- Meet toileting, food, and hydration needs promptly.
- Avoid busy or confusing settings when they increase disorientation.
- Remove access to car keys when driving is no longer safe.
- Use identification, labeled clothing, or optional GPS.
What should you do if the person is missing?
Treat an unexplained absence as urgent, even in daylight or after an apparently routine departure. Do not wait to see whether the person returns on their own.
Begin searching immediately and check nearby hazards, particularly water and heavy-traffic roads. Have the person's recent photograph ready. If the person is not found within 15 minutes, call 911, according to the Alzheimer's Association response guidance.
