Begin searching immediately when a person with dementia is missing. Search nearby and at familiar destinations, then call 911 if the person is not found within 15 minutes—or sooner if danger is likely—and clearly say the missing person has dementia. Give responders a recent photo, identifying details, likely destinations, previous wandering patterns and nearby hazards.
What to do in the first few minutes
A missing person with dementia is an emergency even if they have wandered before and returned safely. The Alzheimer’s Association’s core instruction is to “Begin search-and-rescue efforts immediately.” Use a calm, organized response rather than waiting to see whether the person comes home on their own.

1. Search the immediate area and familiar places
- Note when and where the person was last seen, what they were wearing, whether they had a phone or identification, and which direction they may have taken.
- Check the home, yard, driveway, garage, nearby streets and other places the person could reach quickly.
- Search familiar destinations and routes, including places the person has visited or wandered to before. Many people who wander are found within 1.5 miles of where they disappeared, according to an Alzheimer’s Association factsheet updated in January 2023. Treat that distance as a starting point, not a search boundary; the person may be farther away.
- Ask neighbors, relatives and friends to look or report sightings. Give each helper a defined area so that streets and hazards are not overlooked.
Keep one person available by phone and at the home or last-known location in case the person returns or responders need information. Record which areas have been checked and when, so searchers do not duplicate work.

2. Call 911 at 15 minutes—or sooner when circumstances are dangerous
If the person has not been found after 15 minutes, call 911 in the United States to file a missing-person report. Do not wait 15 minutes when weather, traffic, water, steep terrain, darkness, medical needs or another immediate threat makes the situation urgent. Tell the dispatcher plainly that the missing person has dementia. That detail affects how responders assess the risk and organize the search.
If you are outside the United States, use your local emergency number and provide the same information. Continue safe searching while emergency services are being contacted; do not send untrained helpers into dangerous areas.
3. Give responders a useful information packet
Have these details ready, either verbally or in a message:
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- A recent, close-up photograph that shows the person’s current appearance.
- Full name, age, height, approximate weight, hair color, glasses, mobility aids, medical conditions and other identifying features.
- Clothing and shoes worn, items carried and whether the person has a phone, identification bracelet or tracking device.
- Last-known location and time, likely destinations, normal walking or driving routes and any previous wandering pattern.
- Nearby hazards such as ponds, rivers, busy roads, rail lines, stairwells, tunnels, wooded areas or dense vegetation.
- Whether the person may respond to a familiar name, nickname, language or calm approach.
Share the photo and details with responding officers and with neighbors or family members who are helping. Keep updates centralized so that a reported sighting can be checked quickly rather than passed through several people.
4. Search methodically and safely
Work outward from the last-known point, checking likely routes and destinations before expanding. Search places where a person could become hidden, stuck or unable to call for help, including behind buildings, in open sheds, near water, under bridges and in vegetation. The Alzheimer’s Association factsheet suggests considering the person’s dominant-hand direction when choosing where to look first. This is a search consideration, not a prediction or guarantee.

Use daylight, reflective clothing and phone contact where appropriate. Never create a second emergency by entering moving water, unstable structures, traffic lanes or other hazardous areas. Tell the incident coordinator about every sighting, even if it seems uncertain.
What to do when the person is found
Tell 911 or the coordinating authority immediately that the person has been located. Check for obvious injury, exposure, dehydration or distress and request medical help when needed. Approach calmly, identify yourself and avoid arguing about where the person was going. Reassurance and meeting basic needs can help the person settle.
Recommended Free Tools
After the immediate event, write down the time, location, route, trigger and conditions. That record can reveal a pattern—such as a particular hour, task or destination—and improve the household plan. If the person is agitated, confused or unsafe in the current setting, arrange supervision and professional advice rather than leaving them alone.
Why wandering happens and warning signs to watch for
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.” Wandering can become dangerous or life-threatening, especially when a person encounters traffic, water, extreme temperatures or unfamiliar surroundings.
Possible warning signs include:
- Returning late from a familiar walk or drive.
- Difficulty finding familiar places or becoming lost on a routine route.
- Talking about former jobs, appointments or obligations as if they are happening now.
- Asking to go home while already at home.
- Pacing, restlessness or repeated attempts to leave.
- Looking lost after entering a changed or unfamiliar environment.
A warning sign does not prove that wandering will occur, but it identifies times when closer supervision and a prepared response are especially important.

Build a prevention plan before an incident
Create a personal wandering profile
Keep a current photo and a one-page profile where family members can reach it quickly. Include likely destinations, old addresses, former workplaces, places of worship, favorite shops, walking routes, transportation habits, communication preferences and hazards nearby. Share relevant concerns with trusted neighbors so they know whom to call if they see the person alone or confused.
Notice when restlessness occurs and what precedes it. A predictable activity, toileting need, hunger, thirst, fatigue or a wish to complete a familiar task may be part of the pattern. Meeting basic needs, offering reassurance and redirecting toward a meaningful activity can reduce attempts to leave.
Use routine, meaningful activity and supervision
Plan structured activities that match the person’s abilities and interests. Offer movement and companionship at times when pacing usually starts. When visiting a new location, assess exits, noise, lighting and crowding first. Do not leave a person unsupervised in a new environment if confusion, disorientation or agitation is possible; arrange a companion instead.
These measures lower risk but cannot guarantee that wandering will not happen. A person may still leave despite a careful routine, so prevention must be paired with identification and an emergency plan.

Prepare identification and a safe-return plan
The National Institute on Aging recommends an identification item or medical bracelet carrying the person’s name, address and caregiver phone number. If a bracelet is likely to be removed, put identifying information in clothing labels as well. Keep the information current after a move or phone-number change.
NIA identifies MedicAlert + Alzheimer’s Association Safe and Found as an example of a safe-return program and advises calling for local information. NIA notes that the program is not affiliated with NIA and may charge a fee; availability, geographic coverage and enrollment terms can change, so confirm those details directly before relying on it.

Make the home safer without restricting dignity
Choose safeguards for the specific hazard and the person’s response to them. A measure that alarms constantly, causes distress or blocks necessary movement needs adjustment. Never lock a person in at home.
| Risk or situation | Possible safeguard | Check before keeping it |
|---|---|---|
| Door opened unexpectedly | Door chime, opening alert or other caregiver notification | Can the caregiver hear or receive the alert, including at night? |
| Night-time disorientation | Night lights and a clear, safe walking area | Does lighting reduce falls and confusion without creating glare? |
| Visible door cues | Reduce visual cues that suggest leaving, while keeping exits usable for emergencies | Does the change preserve dignity and avoid trapping the person? |
| Unsafe access to a particular door | Suitable locks or latches positioned out of sight, selected with professional guidance | Can everyone evacuate quickly, and is the person monitored rather than confined? |
The Alzheimer’s Association and NIA both emphasize individualizing safeguards. A household plan should include who responds to an alert, where the photo is stored and which neighbor can help.

Location-sharing apps and wearable GPS trackers—including watches and shoe inserts—can help a caregiver stay connected. They should be treated as one layer of safety, not as proof that a person is safe or as a replacement for supervision and emergency response. The Alzheimer’s Association states: “Location tracking is not the same as having a 24-hour companion.”
No tracking system is 100% accurate. Some devices work poorly indoors, some report only a general vicinity, and weather can interfere with location data. A device may also be left behind, lose power, lack a signal or be removed. Test the full setup before an emergency and decide who receives alerts and what that person will do.

| Location-sharing app on a phone | Will the person carry and keep the phone powered on? Can the caregiver view the location? | The phone can be forgotten, turned off or left behind; a displayed location may be outdated or approximate. |
| Shoe-insert tracker | Will the person continue wearing the same shoes, and can the caregiver maintain the device? | It may not be present if shoes are changed; indoor and weather-related limitations still apply. |

Who can help after the emergency
For an active disappearance, call 911 first as described above. For planning, emotional support and local resources, the Alzheimer’s Association 24/7 Helpline is 800-272-3900. The service describes free information, local-resource connections, crisis assistance and emotional support, available around the clock.
Use the helpline to discuss recurring wandering, caregiver strain, community programs and ways to adapt supervision. It does not replace emergency dispatch during a missing-person incident.

A household checklist to keep ready
- Recent close-up photo, refreshed as appearance changes.
- Written description, clothing details, medical needs and communication preferences.
- Likely destinations, prior routes and nearby hazards.
- Names and phone numbers for family, neighbors and the primary caregiver.
- Identification bracelet or labeled clothing, checked for current contact details.
- Agreed search zones and a person responsible for coordinating helpers.
- 911 instructions that explicitly state the person has dementia.
- Tested alerts or tracking equipment, plus a charging and replacement routine.
- Door alerts, night lights and safe walking areas selected for the individual.
Review the checklist after every incident, move, medication change or change in mobility. A prepared response cannot eliminate wandering, but it can reduce delay, improve the information responders receive and help preserve the person’s safety and dignity.
