Exit-seeking — deliberate, goal-directed attempts by a person with dementia to leave their home or a secured area — is one of the most dangerous behaviors families face, and it deserves a plan before it happens. The core risks to address are unsecured exits, the lack of a rapid-response plan for the first 24 hours, and the assumption that only people with severe dementia try to leave.
The scale is larger than most families expect. The Alzheimer's Association reports that 6 in 10 people living with dementia will wander or become lost at least once, and many do so repeatedly. That makes exit-seeking a mainstream caregiving issue, not a rare emergency.

How exit-seeking differs from ordinary wandering
Clinicians separate the two behaviors because they call for different responses. General wandering is often aimless movement — pacing a hallway, drifting between rooms. Exit-seeking, as described in caregiver guidance from the National Council of Certified Dementia Practitioners, is purposeful: the person is trying to get out, often with urgency or visible distress. The goal usually feels real and reasonable to the person.
Common drivers are beliefs such as needing to "go home" (even while at home), pick up a child, or get to work. Arguing with the belief rarely works; the underlying need — safety, purpose, routine — is what caregivers should address. This distinction matters for prevention. Aimless wandering inside a safe space can often be tolerated. Exit-seeking cannot, because it points directly at the door.
Why the first 24 hours decide the outcome
time missing is the single strongest predictor of survival. Search-and-rescue research by Robert Koester, summarized in Undark's reporting on the science of search and rescue, aligns with Alzheimer's Association figures: roughly half of people with dementia who are not found within 24 hours suffer serious injury or death, while cases resolved inside 24 hours have about a 95% chance of the person being found alive. International data confirm the danger.
A Japanese national study of dementia-related missing incidents, published by Taniguchi and colleagues, examined 673 cases from 2015 and found 67 ended in death — most often from hypothermia or drowning — with longer time missing the strongest mortality predictor. The practical lesson: never "wait and see." Call police immediately. No waiting period applies to a missing person with dementia.
What to tell searchers if your relative goes missing
Koester's database of tens of thousands of lost-person cases gives families concrete guidance to hand to police. According to his lost-person behavior research, people with dementia are typically found within about 1.5 miles of where they started, and roughly half of those not on a road or trail are within 15 meters of one. That means searchers should sweep road and trail edges close to home first, including brush and ditches just off the pavement — people with dementia often do not call out or respond to their name.
Share the person's former addresses, old workplaces, and favorite places, since exit-seeking is frequently aimed at a specific remembered destination. Forty-two states plus the District of Columbia operate Silver Alert or similar rapid-notification programs that broadcast details through media and highway signs. File the police report first; the alert follows from it.
Securing the home without turning it into a cell
The National Institute on Aging recommends layered defenses rather than one lock. Its guidance on wandering includes: Layering matters because any single measure fails: a lock left open, a tracker left uncharged. Pair physical barriers with engagement — exit attempts often spike when the person is bored, anxious, or following an old routine such as leaving for work at 5 p.m.
Redirecting to a task at that hour can prevent the attempt entirely. One safety caveat: never lock someone inside alone. Barriers are for supervised homes; an unattended locked house becomes a fire risk.
- Deadbolts or secondary locks placed high or low on exit doors, outside the person's habitual line of sight
- "STOP" or "DO NOT ENTER" signs on doors that lead outside
- ID jewelry or labeled clothing worn at all times
- A GPS tracker — a wearable or phone-based device that reports the person's location in real time
Don't wait for late-stage dementia
Many families secure exits only after a frightening incident, reasoning that their relative is "not that far along." The research says otherwise. A study of community-dwelling older adults by Rowe and colleagues found eloping behaviors in about 44% of people with even mild dementia. Early-stage exits can be more dangerous, not less.
A person with mild dementia may still drive, use transit, or walk miles — widening the search area far beyond the typical 1.5-mile radius — while lacking the judgment to get home. Enrollment in a 24/7 response program is the step to take now, before the first incident. The NIA points families to MedicAlert's "Safe and Found" program run with the Alzheimer's Association (800-432-5378), which pairs ID jewelry with a national emergency response network so responders anywhere can identify the person and reach family.
Frequently Asked Questions
Is it too early to install door alarms if my parent has only mild dementia?
No. Research summarized by Rowe and colleagues found eloping behaviors in about 44% of people with mild dementia, so secure exits at diagnosis, not after an incident.
How long must I wait before reporting a person with dementia missing?
There is no waiting period. Call police immediately; delay is the strongest predictor of a fatal outcome, and Silver Alert systems in 42 states plus D.C. can broadcast details quickly.
Where are missing people with dementia usually found?
Search-and-rescue data show most are found within about 1.5 miles of their starting point, and about half of those off a road or trail are within 15 meters of one.
