Wandering and getting lost

Wandering means a person with dementia walks or drives away and cannot find the way back. It may happen once, or again and again. It can happen at any stage, even when the person still seems to be doing well.¹

Getting lost is one of the most dangerous things that can happen in dementia. A person may not know their address, may not ask for help, and may not notice cold, heat, traffic or water. This page explains why it happens, how to lower the risk, which ID programs help, and what to do in the first minutes if someone is missing.

Why does a person with dementia wander?

Wandering is not random, even when it looks that way. Dementia damages the parts of the brain that handle memory, direction and judgment. The person may set out with a clear goal, then forget the goal or the way back.

Common reasons include:

• Searching for the past. The person may try to go to an old job, an old home, or to pick up children who are now grown. Wanting to "go home" while already at home is very common.¹
• A basic need. Looking for a bathroom, food or water, or trying to get out of a room that is too hot or noisy.¹
• Feeling lost or scared. New places, crowds and busy stores can cause panic and a wish to leave.¹
• Restlessness and boredom. Too little to do, or energy that needs an outlet. Pacing often comes before leaving.¹
• Time of day. Many people get more confused and restless in the late afternoon and evening. This is called sundowning.¹
• Pain or discomfort the person cannot put into words, such as constipation, a full bladder, or an infection.

Looking for the reason is the first step. See the dementia symptoms hub for how to think about behavior as a message about an unmet need.

Warning signs to watch for

These signs suggest a person may be at risk of wandering:¹

• Coming back later than usual from a walk or a drive
• Forgetting how to get to places they know well
• Talking about old duties, like going to work
• Saying "I want to go home" when they are home
• Pacing, restlessness or doing the same motion over and over
• Trouble finding the bathroom, bedroom or kitchen at home
• Asking where old friends or family members are
• Seeming lost in a new or changed place
• Getting anxious in crowded places

If you see these signs, start the steps below now. Do not wait for the first time the person gets lost. Writing down when restlessness happens, and what came before it, can show a pattern. A behavior diary can help.

How to lower the risk day to day

In the early stage

When the person still goes out alone, agree on a daily check-in time. Go over the day's plans together. Arrange a companion for times when you are not available.¹

Driving

A person who gets lost on foot may also get lost in a car, sometimes far from home. If the person still drives safely, a GPS device can help. If they no longer drive, keep car keys out of sight and reach.¹ Read driving and dementia for how to have this talk.

Making the home safer

These changes slow the person down at the door and alert you when they leave:¹

• Put deadbolts or slide locks high or low on outside doors, out of the person's line of sight.
• Use door alarms, bells on the door, or pressure mats that chime when someone steps on them.
• Disguise doors. A curtain, a painted door that matches the wall, or a cloth banner can make a door less noticeable. A black mat or strip in front of a door may look like a hole, and some people will not cross it.
• Night lights in halls, bathrooms and bedrooms help with night trips to the toilet.
• Fence and gate the yard, and secure stairs.
• Keep coats, shoes, purses and keys out of sight, since these can be cues to leave.

ID and search programs

Even with good planning, some people will still slip away. ID and search programs help strangers and police know who the person is and how to reach you. Ask about cost when you sign up, since prices and plans change.

MedicAlert

MedicAlert runs a wandering support service with the Alzheimer's Association. A member wears an ID that says "Call MedicAlert," along with the person's name and that they have dementia. When a person is reported missing, the service can share the member's medical and ID details with police, EMS and hospitals. It can also send out missing-person flyers and contact family once the person is found.²

ID options include bracelets, necklaces, shoe tags, wallet cards and tags with a QR code (a square barcode a phone can scan). For someone who tends to take things off, MedicAlert suggests an ID with a clasp that is hard to remove.² The service needs an active membership plan to work.²

Project Lifesaver

Project Lifesaver is run by local law enforcement, fire and rescue, or search teams, with training and equipment from Project Lifesaver International. Each person wears a transmitter that sends out a signal unique to them. If the person goes missing, you call the local agency, and trained responders follow that signal.⁴

The program says most searches take less than 30 minutes.⁴ It reports more than 4,600 people rescued, as of October 2026.³ Use the "Find an Agency" tool on its website, or call your local sheriff's office or police department, to see if your area takes part.³ Transmitter batteries need to be changed on a schedule, so ask the agency who does this.

Simple steps that cost little

• Sew or iron name labels into clothes, with a phone number but not the home address.
• Put a card in the person's wallet or pocket that says they have memory loss and lists your phone number.
• Tell neighbors, local shop owners and building staff about the condition. Ask them to call you if they see the person out alone.¹

Make a plan before anyone goes missing

Do this now, while things are calm. Keep the plan by the phone and share it with family and helpers.¹

1. Keep a recent, close-up color photo of the person ready to give to police. Update it every few months.
2. Write down key facts: height, weight, hair and eye color, scars, glasses, hearing aids, medical conditions, and medicines.
3. List the places the person might go, such as old homes, past workplaces, a place of worship, or a favorite restaurant or store.
4. Mark dangers near home: ponds, pools, creeks, busy roads, woods, tunnels and open stairwells.
5. Note whether the person is right- or left-handed. People who wander often head in the direction of their dominant hand.
6. Sign up for an ID or search program and keep the member number with your plan.

The emergency and disaster planning page has more on keeping medical information ready. A care circle can help you decide who will search where.

What to do if the person is missing

1. Search the home and nearby area first. Check closets, the car, the garage, the yard, sheds, and under porches.¹
2. Check nearby hazards and hiding places: ponds, tree lines, fence lines and thick brush.¹
3. Check places the person has gone before.¹
4. Call 911. Say the person has dementia. Give the photo, a description, what they were wearing, and any medical needs.¹ There is no rule that you must wait 24 hours.
5. Report to your ID program. If the person is a MedicAlert member, call to report them missing so the service can alert responders.² If they are enrolled in Project Lifesaver, tell the 911 dispatcher and the local agency so they can start tracking.⁴
6. Stay by the phone, or leave someone at home, in case the person returns or someone calls.

Virginia's Senior Alert

Virginia has a Senior Alert program, run with the Virginia State Police. It can send a public alert through TV, radio, the internet and other media when an adult over 60 with dementia or another cognitive impairment is missing. Police must find that the disappearance poses a real threat to the person's health and safety.⁵

Families do not turn on the alert themselves. You report the person missing to your local police. Local police then work with the State Police, which decides on a regional or statewide alert.⁵ Other states have similar programs, often called Silver Alerts. Ask your local police how it works where you live.

When the person is found

The person may be scared, tired, cold or dehydrated. Stay calm and kind. Do not scold. Offer water and a warm place to sit, and check for cuts, bruises or signs of a fall. If they seem hurt, very confused, or very weak, call 911 or get them seen by a doctor that day.

Afterward, look for what led to the event. Was it a time of day, a need, or a change in routine? Tell the person's doctor, since a new or sudden increase in wandering can be a sign of pain, an infection or a medicine side effect.

When to get help

Call 911 right away if the person is missing and not found within 15 minutes, or sooner if they are in danger.¹

Talk with the person's doctor if:

• Wandering is new, or suddenly happens much more often
• The person seems to be in pain, has trouble using the toilet, or has a fever
• Restlessness is worse at night and you are not sleeping
• You wonder whether a medicine is adding to confusion. Talk with the doctor or pharmacist before changing anything.

Wandering is also a common reason families look at more supervision, such as in-home care, respite care or memory care. Constant watching is exhausting. If you feel worn out, see caregiver stress and burnout.
