Wandering and Dementia: Why It Happens and How to Prevent It

The word makes it sound aimless. It rarely is. Someone leaves because they are going to work, or collecting a child from a school that closed thirty years ago, or going home while standing in the home they have lived in for decades.

That last one confuses families most. Home, to someone with dementia, is often a house from earlier in life, and the wish to go there is a wish to be somewhere safe and familiar rather than a comment on their current address.

Others are looking for a bathroom and cannot find it, or are restless and understimulated, or are following a lifelong routine at the time of day they always did. Working out which of these it is tells you what will prevent it, which is why a door alarm alone is rarely the answer.

Wandering usually announces itself before it happens. Pacing, or repeatedly trying doors and windows. Talking about needing to go somewhere or do something. Restlessness at a consistent time of day, most often late afternoon and early evening.

Confusion about where they are in a familiar place, or asking to go home while at home. Any of these is worth acting on before the first incident rather than after it.

Address the reason first. If it happens at the same time each day, a walk or an activity at that hour often removes the need entirely. If they are looking for the bathroom, a sign on the door and a light left on at night does more than any lock. If the trigger is boredom, that is a care plan problem rather than a security one.

Then make leaving harder without making the home feel like a lock-up. Locks placed high or low on the door, outside the usual line of sight. Door and window alarms, or simple contact sensors that chime. A dark mat in front of an exit, which can read as a hole and stop someone crossing. Curtains over glass doors that show an appealing outside.

And remove the prompts. Car keys, coats and handbags left by the door are instructions to leave for someone who is following a familiar routine.

Almost every family that experiences wandering had prevention in place. Prepare for the event as well as against it.

A current photograph, taken this year, kept somewhere you can find it in a panic. A written note of height, build, and what they usually wear. A medical identification bracelet with the condition and a phone number. Tell the immediate neighbours, which is uncomfortable and is the single most useful thing on this list, because they are the people who will notice first.

Many local police departments run a registration scheme for vulnerable adults, and some areas have location services through the Alzheimer's Association or local agencies. Ask what exists in your county before you need it.

Search the house and immediate garden first, including cupboards and behind furniture, because people are found inside more often than families expect.

Then call the police. Do not wait, and do not worry about whether it is too soon. There is no waiting period for a vulnerable missing adult and the first hours matter most. Tell them it is a person with dementia, because that changes how the search is run.

Most people are found within a mile or so of home, often along a route they walked for years, and frequently heading in the direction of a former address or workplace. Say that on the call.

One episode of wandering is a signal that the current arrangement has been outgrown, particularly if it happened at night or the person was not able to find their way back.

It is the point at which many families move from checking in to overnight cover, because the risk concentrates after dark and a person who leaves at three in the morning is not found quickly.
