Start looking immediately. Search nearby and check familiar destinations, then call 911 if the person is not found within 15 minutes—or sooner if conditions suggest immediate danger. Tell responders the person has dementia, provide a recent photo and identifying details, and explain likely destinations, previous wandering routes and local hazards. The steps below turn that urgent response into a coordinated search and a longer-term safety plan.
What to do in the first minutes
The Alzheimer’s Association says to “Begin search-and-rescue efforts immediately.” Do not wait to see whether the person returns on their own or assume that a short absence is harmless. Dementia can affect judgment, orientation and the ability to recognize a familiar route.
- Check the immediate area. Search the home, yard, driveway, nearby paths and places the person can reach quickly. Ask neighbors to look from their properties and to report sightings rather than confronting or pursuing the person unsafely.
- Check familiar destinations. Look at places the person has visited before, such as a former home or workplace, a regular shop, a place of worship, a transit stop or a usual walking route. Use the person’s previous wandering pattern to decide which locations to check first.
- Call 911 after 15 minutes if the person is still missing. The 15-minute interval is a starting rule from Alzheimer’s Association guidance, not a reason to delay when there is immediate danger. Call at once for severe weather, nearby water, heavy traffic, steep terrain, medical vulnerability or any other urgent risk.
- Say explicitly that the missing person has dementia. Give the dispatcher the person’s name, age, height, clothing, medical conditions, communication limitations, mobility, likely destinations and the time and place they were last seen.
- Send a current photo and a concise description. A close-up image is more useful than an old group photograph. Include hair, glasses, tattoos, scars, gait, a preferred name and anything distinctive about the person’s clothing or belongings.
Keep one person at the last-known location in case the individual returns or a witness arrives. Other helpers can search assigned areas, but everyone should report sightings to one coordinator or to 911 so efforts do not become duplicated or unsafe.

How to search methodically
Start close, then expand
Many people who wander are found within 1.5 miles of where they disappeared, according to an Alzheimer’s Association factsheet updated January 2023. Treat that distance as a place to begin, not a boundary: a person may travel farther, enter a vehicle or follow a route that crosses the initial area.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Divide the search into sectors and record which streets, buildings and paths have been checked. Mark the time each area was searched so another person can revisit it without assuming it is covered. Ask businesses, transit staff and nearby residents to preserve security-camera footage and to call 911 if they see the person.
Prioritize hazards
Search places where a disoriented person could be injured or become difficult to see:
- ponds, rivers, swimming pools, canals and drainage areas;
- busy roads, parking lots, rail lines and transit platforms;
- stairwells, tunnels, garages and construction areas;
- dense vegetation, ravines, sheds and abandoned structures; and
- outdoor areas exposed to heat, cold, rain or wind.
Search teams should use a buddy system, carry a phone or radio and avoid entering dangerous areas alone. The Alzheimer’s Association factsheet suggests considering the person’s dominant-hand direction when deciding how to extend a search. This is a search consideration, not a prediction: do not exclude routes in the opposite direction.

- full name, preferred name, age and a recent close-up photograph;
- height, approximate weight, hair and eye color, glasses, facial hair, scars, tattoos and other identifying features;
- the exact last-known location and time, clothing, shoes, coat, hat, bag and mobility aids;

- places the person used to live or work, regular destinations and routes taken during earlier incidents;
- nearby water, roads, wooded areas, public transport and other hazards; and
- your name, phone number and the names and numbers of anyone coordinating the search.
Tell volunteers not to frighten, restrain or argue with the person if they are located. They should keep a safe distance, use a calm voice, identify themselves and call 911 or the designated coordinator with the exact location. Follow police instructions about entering private property, searching waterways or approaching traffic.
What to do when the person is found
Approach slowly and use the person’s preferred name. Reassurance is generally more effective than asking repeated questions about where they have been. Offer water, shade or warmth as appropriate, and look for signs of injury, exposure, dehydration, breathing trouble or acute illness. Call 911 for a medical emergency or if the person cannot be safely moved.
Tell law enforcement and every search group that the person has been found so the response can be stood down. Write down where and when the person was located, what they were wearing and what may have triggered the departure. That record can reveal a recurring time, destination or unmet need that should be addressed in the care plan.
Recognizing wandering risk before an incident
Wandering can occur at any stage of dementia. The Alzheimer’s Association reports that Six in 10 people living with dementia will wander at least once; many do so repeatedly.
The organization also warns that wandering can be dangerous or life-threatening.

Possible warning signs include:
- returning late from a familiar walk or drive;
- difficulty finding familiar places;
- talking about a former job, appointment or other past obligation as if it is current;
- asking to go home while already at home;
- pacing, restlessness or repeatedly moving toward a door; and
- appearing lost or unusually agitated in a changed environment.
Keep a simple log of the time, setting, activity and apparent need surrounding these behaviors. Patterns can help a caregiver schedule support before the high-risk period rather than reacting after the person has left.
Reducing risk without restricting dignity
Use routine and meaningful activity
Plan structured, meaningful activities and regular movement during times when the person is usually restless. Meet basic needs such as hunger, thirst, toileting, comfort and sleep. Reassure the person and acknowledge what they are trying to do instead of correcting every mistaken belief. These steps may reduce risk, but the Alzheimer’s Association cautions that no prevention plan can guarantee wandering will not occur.
Plan for unfamiliar places
Assess a new home, clinic, hotel or event before arrival. Do not leave a person unsupervised in a new setting if confusion, disorientation or agitation is possible. Arrange a companion, identify quiet walking areas and carry the person’s identification and emergency contacts.

- place door chimes or opening alerts where a caregiver can hear them;
- use suitable locks positioned out of sight if they do not create a fire or emergency egress hazard;
- add night lights along routes to the bathroom and other frequently used areas;
- provide a safe area for walking indoors or outdoors; and
- reduce visual cues that suggest an exit, while keeping essential rooms easy to find.
Never lock a person in the home. Safeguards should support safe movement, preserve dignity and comply with local fire and building requirements.
Identification and community preparation
Keep a recent photo in an accessible place and update it as the person’s appearance changes. Tell trusted neighbors what to do if they see the person: call you or 911, give the exact location and avoid attempting a risky physical intervention.
The National Institute on Aging recommends an identification item or medical bracelet carrying the person’s name, address and caregiver phone number. If the person removes a bracelet, labels inside clothing may provide another way to identify them. Keep the information current and avoid displaying more personal information than is necessary for a safe return.
Before an emergency, identify likely destinations, dangerous areas, alternate contacts and who can search. Ask a clinician, social worker or local aging organization about a wandering-response or safe-return service. The NIA identifies MedicAlert + Alzheimer’s Association Safe and Found as an example; it advises calling for local information and notes that the program is not affiliated with NIA and may charge a fee. Availability, geographic coverage, enrollment terms and fees can change, so verify those details directly before relying on the service.

GPS trackers, phones and door alerts: what each can and cannot do
Location-sharing apps and wearable GPS devices—including watches and shoe inserts—can give caregivers another way to find a person. They are safety layers, not substitutes for supervision or emergency response. The Alzheimer’s Association states, Location tracking is not the same as having a 24-hour companion.
| Safety tool | Useful role | Limits and planning questions |
|---|---|---|
| Medical ID bracelet or clothing label | Provides the person’s name, address and caregiver phone number when someone finds them. | The person may remove a bracelet; add a clothing label and keep details updated. |
| Wearable GPS tracker | Can share a location with caregivers outdoors when the person wears or carries it. | No system is 100% accurate. Some devices work poorly indoors, some show only a general vicinity, and weather can interfere. Decide who receives alerts and what happens if the device is lost, uncharged or unavailable. |
| Location-sharing phone or app | Can help a caregiver check a connected device’s reported position. | It depends on the person carrying, charging and operating the phone; a reported position may not be exact or current. Maintain a search and 911 plan. |
| Door chime or opening alert | Notifies a caregiver when a monitored door opens. | It covers a particular opening, not every route out, and does not prevent a person from leaving. Test that the alert can be heard or received when the caregiver is asleep or in another room. |
Choose a tool by asking five practical questions: Will the person wear or carry it? Does it work where the person is most likely to go, indoors or outdoors? Does it provide a precise location or only a general area? Who receives and acts on alerts? What is the backup if the device fails? Test the complete process, including charging, alert delivery and contacting help.
A repeatable household response plan
Write the plan in plain language and place copies near the phone, with trusted neighbors and in the person’s emergency file.
- Confirm the last-known time and place. Check the home, yard, usual routes and familiar destinations.
- Assign roles. One person stays available for calls; others search safe sectors and report sightings.
- Prepare the information packet. Include the current photo, description, medical needs, likely destinations and hazards.
- Escalate to 911. If the person is not found within 15 minutes—or danger is already apparent—call and state that the person has dementia.
- Track the response. Record areas searched, times, sightings and instructions from responders.
- Update prevention measures afterward. Review what happened, adjust routines or safeguards and replace outdated photos or contact details.
Where caregivers can get support
The Alzheimer’s Association 24/7 Helpline is 800-272-3900. It offers free information, local resources, crisis assistance and emotional support around the clock. Use 911 for an active missing-person emergency; the helpline is not a substitute for emergency dispatch.
For general guidance, see the Alzheimer’s Association’s Wandering page, the National Institute on Aging’s Coping With Alzheimer’s Behaviors: Wandering and Getting Lost, and the Alzheimer’s Association factsheet Wandering and Getting Lost: Who’s at Risk and How to Be Prepared.

Quick Recap
Key actions to remember
- Begin searching immediately when a person with dementia is missing.
- Call 911 after 15 minutes if they have not been found, or immediately when danger is evident, and identify the dementia.
- Give responders a recent photo, identifying details, likely destinations, prior patterns and hazards.
- Prepare identification, contacts, neighbors and a household plan before an incident.
- Use GPS and door alerts as imperfect layers of support, never as a replacement for a companion or emergency response.
- Reduce risk while preserving dignity; never lock a person in at home.
