Dementia and Wandering Risk: How Families Can Protect a Loved One Safely

Why Wandering Happens and Why It Matters

Wandering is one of the most common and potentially dangerous behaviours associated with dementia. Research suggests that around six in ten people with dementia will wander at some point during the course of their illness. Despite how common it is, it remains one of the aspects of caring for a person with dementia that families feel least prepared for.

Understanding why wandering happens is the starting point for managing it effectively. People with dementia wander for reasons that make complete sense to them in the moment: they may be following an old routine from earlier in life, such as going to work or collecting children from school. They may be looking for someone they miss, often a parent or spouse who may have died. They may be responding to discomfort, boredom, or anxiety that they cannot express directly. They may simply be confused about where they are and trying to get somewhere that feels familiar.

This framing matters because it shifts the response from frustration or alarm to problem-solving. The person is not being difficult. They are trying to meet a need or fulfil a purpose that feels real and urgent to them. Effective management addresses those underlying needs while keeping the person safe.

Assessing the Risk

Not everyone with dementia is at equal risk of wandering. Factors that increase risk include: a history of an active lifestyle or work that involved a lot of movement; previous experience of getting lost even before dementia; significant restlessness, agitation, or pacing; expressions of wanting to go home even when already at home; and a tendency to follow other people out of doors.

Certain times of day carry higher risk for many people with dementia. Sundowning, the pattern of increased confusion and agitation in the late afternoon and early evening, is associated with increased wandering behaviour at those times. Understanding your family member's specific patterns allows you to be more vigilant during higher-risk periods and to build routines that address their needs before the urge to wander becomes urgent.

Prevention: Environmental Adaptations

The home environment can be modified in ways that significantly reduce wandering risk without creating an oppressive or institutional atmosphere. Door alarms that sound when external doors are opened give carers time to respond before a person reaches the street. These are inexpensive, do not require professional installation, and are one of the most effective single interventions available.

Disguising exits can be effective because people with dementia often respond to visual cues rather than logical reasoning. Painting doors the same colour as surrounding walls, covering door handles with cloth covers, or placing a curtain across an exit can make the door less visible and therefore less likely to be approached. This may seem unusual, but it works for many people with dementia and does not involve locking or physically restraining anyone.

Door coverings with a stop sign or a large visual barrier at eye level (a mirror, a poster, a visual pattern that draws the eye) can deter people from attempting to open a door by presenting a visual interruption. Again, this is effective because the person responds to the visual environment rather than applying logical reasoning about whether the door leads outside.

Securing the garden or outdoor space so that it is safely enclosed allows the person with dementia to go outside and move around freely without the risk of reaching the street. If the property allows it, this is one of the best solutions available, because it meets the underlying need for movement and fresh air rather than preventing it.

Prevention: Routine and Activity

Boredom, restlessness, and unmet need are significant drivers of wandering. A structured daily routine that includes meaningful activity, physical movement, and social engagement significantly reduces wandering behaviour in many people with dementia. Activities that draw on long-established skills and interests are particularly effective: someone who was a keen gardener may find great satisfaction in simple garden tasks; someone who spent years in a physical job may benefit from walks or activity that provides similar sensory feedback.

If the urge to wander is related to a specific purpose (going to work, collecting children), it can sometimes be redirected rather than prevented directly. Accompanying the person on a walk and gently redirecting the destination, or engaging them in an activity that feels purposeful, can address the underlying need without confrontation.

Late afternoon and evening activities that are calming and absorbing, such as listening to familiar music, simple craft activities, or looking through photograph albums, can reduce sundowning-related agitation during the higher-risk periods of the day.

Technology and Tracking

GPS tracking devices designed for people with dementia are widely available and have become significantly more sophisticated and discreet. Devices can be worn as watches, carried in a pocket, or sewn into clothing. They allow family members or carers to see the person's location in real time via a smartphone app, and to set alerts that notify them if the person leaves a designated safe area.

The Herbert Protocol is a scheme operating across most UK police forces that allows families to pre-register information about a person with dementia who is at risk of going missing. You fill in a form providing a recent photograph, physical description, details of where the person is likely to go if they wander, and any other relevant information. If the person goes missing, this information is immediately available to police, significantly speeding up the search. Contact your local police force to register, or ask your GP or dementia support worker to help you do so.

ID jewellery, engraved with the person's name and a contact phone number, provides a straightforward identification method if the person is found by a member of the public. This is a simple, inexpensive, and effective measure. The Alzheimer's Society also runs a Safe Walking scheme and can advise on the full range of tools available.

If Your Loved One Goes Missing

Contact the police immediately. There is no minimum waiting period before reporting a missing person with dementia; call 999 if you believe the person is in immediate danger, or 101 for non-emergency situations. Explain that the person has dementia and that you have Herbert Protocol information registered if you do. Police treat missing persons with dementia as a high-priority case.

Alert neighbours, local shopkeepers, and community members who know the person. People with dementia who wander often go to familiar places from their past, so thinking about where those places might be, former workplaces, old family homes, a particular shop or park, can guide where you search.

Contact the Alzheimer's Society helpline on 0333 150 3456, which can provide immediate support and advice during a wandering incident. If you use a GPS device, activate the tracker and share the location information with the police.

After the person is found safely, resist the temptation to express the full extent of your fear and distress to them. For the person with dementia, the experience is unlikely to feel like an emergency; expressing strong distress can increase their anxiety without giving them the cognitive tools to understand why. A calm, warm, matter-of-fact response, getting them comfortable, warm, and fed, is more helpful in the immediate aftermath than an emotional reaction, however understandable that reaction would be.
