Seek professional help when a person with dementia gets lost on a familiar route, changes suddenly, or can no longer be supervised safely at home. If the person is missing, search immediately and call 911 if they are not found within 15 minutes. Getting lost may be part of wandering—movement that could leave the person lost or unsafe. Even when the person returns unharmed, the episode deserves attention because it may reflect worsening dementia or another medical problem.

When does getting lost require a medical appointment?
Contact the person's clinician after any new trouble navigating a familiar place. Examples include becoming confused on the usual walk, failing to reach a regular destination, or returning unusually late from a routine outing. The National Institute on Aging says getting lost on familiar routes, especially alongside new problems with memory, thinking, personality, or judgment, calls for medical attention.
Getting lost does not identify the cause by itself. Tell the clinician when it happened, where the person intended to go, how long they were missing, and whether anything else changed. Include recent medication changes, illness, eating and drinking problems, and unusual behavior.
When is a sudden change more urgent?
Call the clinician immediately if the person suddenly seems more confused, restless, agitated, sleepy, or unlike their usual self. A rapid change should not be assumed to be ordinary dementia progression. The National Institute on Aging warns that fever, infection, medication side effects, and dehydration can cause delirium, a sudden worsening that requires prompt clinical attention.
A clinician can look for these potentially treatable contributors. Describe the difference from the person's normal behavior. "She became lost on her own street today and began pacing last night" gives the clinician more useful information than "her dementia is worse.".
What should you do when the person is missing?
Begin searching immediately. Check the person's usual destinations and nearby routes, but do not delay emergency help while trying to manage the search alone. If the person is not found within 15 minutes, call 911 and clearly state that the missing person has dementia.
The Alzheimer's Association gives this guidance because wandering can affect anyone with dementia, may happen at any stage, and cannot be completely prevented by alarms, identification, GPS, or structured activities alone. Give responders the person's name, description, last known location, direction of travel, and likely destinations. Keep your phone available for updates.
When is a professional safety plan needed?
Ask for professional safety planning after a person becomes lost, repeatedly tries to leave, struggles to reach familiar places, or returns late from routine outings. A clinician, social worker, or care manager can help determine how much supervision the person now needs.
A practical plan may combine: No single safeguard guarantees that wandering will stop. Repeated incidents should prompt reassessment rather than simply adding another lock, alarm, or tracker.
- Door alarms or alerts
- Identification carried or worn by the person
- GPS or another location-tracking tool
- Structured daily activities
- More direct supervision during high-risk times
When is home care no longer safe?
Seek help when family members cannot reliably provide the supervision needed to prevent repeated missing-person emergencies. Wandering, aggression, or a growing need for round-the-clock care may mean that the current arrangement is no longer safe.
Planning should begin before a crisis forces a rushed decision. The National Institute on Aging notes that geriatric care managers—often nurses or social workers—can help families develop a long-term plan when dementia may eventually require continuous care or make the home unsafe because of wandering or aggression. If safe supervision cannot be maintained today, contact the clinician and a care manager today to begin arranging a higher level of care.
