Dementia Wandering: Why It Happens and How to Keep Them Safe

Wandering is common — the Alzheimer’s Association estimates that about 6 in 10 people with dementia will wander at least once. Wandering can look aimless, but from the inside it almost always has a purpose — understanding that purpose is the key to reducing it. A person with dementia may be acting on a memory, a need, or a feeling they can no longer express in words.

• Searching or "going home" — even when they are home, dementia can make a familiar place feel unfamiliar, prompting a search for a home, person, or time that feels real to them.
• Following an old routine — heading "to work" or "to pick up the children," reliving a long-ingrained habit.
• Restlessness or excess energy — a need to move, especially with too little daytime activity.
• Boredom or under-stimulation — with nothing to do, moving becomes the activity.
• Discomfort or an unmet need — pain, hunger, thirst, needing the toilet, or wanting to escape noise or overstimulation.
• Confusion and disorientation, particularly in the late day with sundowning or at night.

Because wandering is need-driven, the most humane and effective first step is to meet those needs — reducing the urge rather than only blocking the door. This preserves dignity and freedom of movement:

• Provide regular activity and exercise — safe daily walks and meaningful activities channel restless energy and reduce the drive to wander.
• Keep a consistent routine so the day feels predictable and less anxiety-provoking — see dementia daily routine.
• Meet needs proactively — regular toileting, meals and drinks, and comfort checks head off wandering driven by discomfort.
• Reassure and redirect when the person wants to leave — validate the feeling ("You want to get home — let’s have a cup of tea first") and gently redirect, as in how to calm a dementia patient.
• Address the timing — if wandering peaks in the late day, work on sundowning; if at night, on sleep.

Alongside meeting needs, make the home safe so that if the urge strikes, the person cannot slip out unnoticed into danger:

• Alert you to exits — fit door alarms or exit sensors so you know immediately if an outside door opens, day or night.
• Make exits less obvious — locks placed high or low out of the usual sight line, or visually camouflaging doors, can reduce the impulse to leave (use judgment and never compromise fire safety or trap the person).
• Use monitoring where helpful — monitoring systems or a bed alarm can alert you to night-time movement.
• Reduce triggers near doors — keep coats, shoes, keys, and bags out of sight if they cue "time to go."
• Secure the wider environment — gates on stairs and, where relevant, in the garden, plus general home safety and fall prevention.

If the person does get out, being able to find them quickly is vital. Prepare these in advance:

• GPS location devices — a GPS tracker worn as a pendant, watch, or in a shoe lets you locate the person quickly if they wander. This is one of the most valuable safeguards for someone at risk.
• Identification on the person — an ID bracelet or card with their name, "memory impairment," and an emergency contact number, so anyone who encounters them can help.
• Consider a wandering-response or "safe return" program if one is available in your area, which helps reunite people quickly.
• Tell neighbors and nearby shops that the person has dementia and may wander, and share your contact number — a watchful community is a real safety net.

The time to prepare is before a wandering incident, so that if it happens you can act fast:

• Keep a recent, clear photo of the person readily available.
• Have a written note of key details — description, medical conditions, medications, places they might head (a former home, workplace, or a favourite spot).
• Know your immediate response plan — where to check first, who to call, and how to give responders the photo and details fast.
• Identify the most likely destinations — people with dementia often head toward a meaningful place from their past.

If a person with dementia is missing, treat it as an emergency — they can be at serious risk from traffic, weather, or getting lost, and time matters:

1. 1

   Search the immediate area right away

   Quickly check the home, garden, and nearby surroundings, and the direction of any likely destination — many people are found close by soon after.

2. 2

   Call emergency services without delay

   If not found within a few minutes, call emergency services. Do not wait — tell them the person has dementia and is a vulnerable adult, and provide the photo and details you prepared.

3. 3

   Use your GPS device

   If the person wears a GPS tracker, use it to locate them and guide responders.

4. 4

   Enlist help

   Alert neighbors, nearby shops, and any wandering-response program, and mobilize family to search likely spots.

5. 5

   After they are safe, review

   Once the person is safe, reflect on what triggered it and tighten prevention — more activity, better exit alerts, or addressing the timing.
