Dementia and wandering: how to keep someone safe

Walking about or trying to leave home can happen for many reasons when someone has dementia. They may be looking for a familiar place, following an old routine, feeling restless, or trying to meet a need they cannot easily explain. It can be worrying for family, but responding with curiosity and planning is usually more helpful than arguing or blaming.

There is no single approach that suits everyone. Work with the person, their care team and local dementia services to make a plan that respects their preferences and fits your home and community. Guidance and available services differ by country.

Start by looking for patterns

Notice when the person wants to leave, where they seem to be going, and what happened beforehand. A simple record can help you spot patterns without assuming you know the reason. Note the time, activity, who was present, what the person said or did, and what seemed to help. A Carer's daily log generator or behaviour and mood log can help the family share observations.

Consider possible everyday needs: a walk, company, the toilet, food or drink, a familiar activity, or reassurance. A change in routine or an unfamiliar environment may also be relevant. Ask the person calmly what they need, and listen even if their explanation is unclear. Avoid correcting or confronting them if that increases distress; a gentle change of subject or offer to walk together may work better.

If walking about or confusion starts suddenly, becomes markedly different, or comes with other new concerns, contact a GP or another appropriate health professional promptly. They can assess what may be contributing and advise on next steps. This guide cannot identify the cause.

Make a plan with the person

Talk about safety at a calm time, not only during a difficult moment. Include the person as much as they wish and are able. Ask what feels important to them: going outside independently, visiting a familiar place, or keeping a daily walk. Agree on practical ways to support those preferences, such as walking together at a predictable time or arranging a check-in.

Share the plan with relatives, trusted neighbours and anyone who provides care, with the person’s agreement where possible. Decide who will respond if the person leaves unexpectedly, how you will contact one another, and who will call local emergency services if needed. A Weekly care rota builder can help clarify who is available and when.

Keep key information easy to find. An emergency information sheet for an older person or emergency contact sheet can list current contacts, a recent photo, places the person often visits, communication preferences, and details that may help others identify them. Share sensitive information only with people who need it, and keep it up to date.

Reduce risks at home without creating new ones

Walk through the home and the route to the garden or front door. Look for trip hazards, poor lighting, confusing signs, and doors that open directly onto a busy road or other hazard. A home safety checklist for older people can help you review the space. Simple changes might include clearer signs, a night-light, or keeping frequently used items easy to find.

Think carefully before changing locks, disguising doors or using alarms. These may not suit the person, and a measure that delays them could also delay help in an emergency. Do not block emergency exits or use a measure that traps someone. If you are considering restrictions, ask a qualified local professional about safer alternatives and the rules where you live. Laws and standards on consent, capacity and restrictions differ by country.

Some families consider an identification card, bracelet or location device. Discuss options with the person and consider their comfort, privacy, ability to use the device, battery life and who will respond to an alert. These tools are not a guarantee of safety and may not be available or appropriate everywhere. A local dementia organisation or care professional may know what services exist in your area.

Make outdoor time more predictable

If the person enjoys walking, build it into the day where practical. Choose familiar, well-lit routes and agree whether someone will accompany them or check in. Keep weather-appropriate clothing and suitable footwear ready. For outings, agree on a meeting point and a simple way to ask for help. A family member or companion can carry emergency contact details and a recent photo, subject to the person’s wishes and privacy.

Tell trusted neighbours or nearby shopkeepers what would be helpful if they see the person alone or looking unsure. Explain whom they should contact. Avoid sharing more personal information than needed. If you use a device or identification item, check it regularly and make sure the contact details are current.

If the person cannot be found

If you cannot locate them, act promptly. Contact local emergency services or the police according to the procedures in your country; do not wait for an arbitrary amount of time if you believe there is immediate danger. Ask another person to help while you search nearby familiar places, if it is safe to do so.

Give responders a recent photo, the person’s name and description, what they were wearing, when and where they were last seen, places they may go, and any information that could help them communicate with the person. Tell responders about immediate hazards or support needs. Keep your phone available and record who has been contacted and what has been checked. Local missing-person procedures and specialist support programmes vary, so ask your local authorities or dementia organisation in advance how to report a concern.

When the person is found, focus first on their immediate wellbeing and reassurance. Once things are calm, review what happened with them and the care team. Consider what might make the next outing or day safer, rather than treating the incident as a failure.

Get support and review the plan

Ask a GP, dementia specialist, occupational therapist or local dementia service for advice tailored to the person and their home. They can help you think through daily routines, environmental changes and support options. Guidance on walking about and home safety is available from Alzheimer’s Society, the US National Institute on Aging, and the Alzheimer’s Association. These organisations serve different countries, so check local services and rules rather than assuming a programme is available where you live.

Review the plan after a change in the person’s routine, living situation, mobility or support team, and after any incident. Caring for someone who may walk away can be tiring. Share responsibility where possible and ask local services about respite or carer support. A workable plan should help the person keep as much freedom as possible while giving family members clear, realistic steps to follow.
