Preventing Wandering Without Locking Someone In
Wandering is usually purposeful, not random. Working out the purpose is what actually stops it.
Few things frighten families more than the possibility of a parent with dementia leaving the house and not being able to get back. The instinct is to lock the doors, and that instinct is both understandable and mostly wrong.
Confinement tends to increase agitation, which increases the drive to leave, which produces more determined attempts at worse moments. It also creates a genuine hazard in a fire. There are better approaches, and they start with understanding what is actually happening.
It is almost never aimless
The word wandering suggests drifting about without purpose. In practice, somebody leaving the house usually has a reason that is entirely coherent from the inside.
The common ones: going to work at a job they retired from twenty years ago; going to collect children who are now in their fifties; going home, while standing in the house they have lived in for decades, because home means a childhood address; looking for a spouse who has died; or simply needing the toilet and going out of the wrong door.
Boredom and physical restlessness account for a lot of the rest. Somebody who used to walk several miles a day and is now sitting indoors is not confused when they want to go out. They are under-exercised.
Keep a note of when it happens and what was going on immediately before. The pattern is usually obvious within two weeks: a time of day, a trigger, an unmet need. Fix the pattern and you fix most of the incidents.
Address the reason first
This does more than any lock.
If it is time-of-day related, particularly late afternoon, that overlaps heavily with sundowning, and the same measures help. Our piece on why late afternoon is harder covers it.
If it is restlessness, build genuine physical activity into the day, ideally outdoors and ideally in the afternoon. A proper walk with somebody is both the treatment and the thing being sought.
If it is a job or a duty, arguing about the facts rarely works and often escalates. Redirecting toward the underlying feeling works better: acknowledging that they are needed, then offering something purposeful to do here.
If it is looking for a person, reassurance and distraction generally beat correction. Repeatedly telling somebody their spouse died means they hear that news as though for the first time, over and over.
Make the exits less obvious
Environmental changes work better than locks because they reduce the impulse rather than blocking it.
Practical measures: move door locks well above or below eye level, where they are outside the usual visual field; use a curtain or a screen over an external door so it does not read as an exit; avoid dark mats near doorways, which some people with dementia perceive as holes; and remove coats, keys, shoes and bags from beside the front door, since those are cues that it is time to leave.
Making other places more attractive helps too. If the garden is safe and accessible, the urge to go outside can often be satisfied there.
Alerting, rather than confining
The aim is to know immediately, not to prevent movement inside the house.
Simple door chimes or alarms tell you when a door has opened. Motion sensors and pressure mats can alert to somebody getting up at night. Some families use video doorbells, which give both notification and a record of the direction taken.
Keep it proportionate and remember that anything monitoring an adult raises questions about dignity and consent, particularly early in dementia when someone may have clear views about it. Involve them while they can be involved.
Prepare for the time it happens anyway
Assume at some point it will, and do the preparation while nothing is wrong. The first fifteen minutes matter enormously and are not the moment to be improvising.
- A current photograph on your phone, and a note of what they usually wear.
- Identification on the person. A bracelet, a card in a wallet, or a label sewn into a coat, with a phone number rather than a home address.
- Tell the neighbors. The single most effective measure available, and the one families skip out of embarrassment. Neighbors who know are the reason most of these end quickly and quietly.
- A written list of the places they are likely to head for: a former address, a workplace, a church, a store they used.
- Consider a locating device, and check it is something they will actually keep on. A tracker in a coat pocket is no use in July.
- Look into local registry programs. Many police departments run schemes for residents at risk of going missing; check what exists locally.
Call for help early. Families routinely spend an hour searching alone out of embarrassment before calling anyone, and that hour is the one that mattered.
The locking question, honestly
There are situations where a lock is the least bad option, usually at night and usually temporarily. If you get there, do it with clear eyes.
Anything that prevents somebody leaving also prevents them leaving in a fire, so there must be a plan for that, and somebody in the house who can open it immediately. A key-operated deadbolt with the key removed is not acceptable if the person is ever alone.
Treat it as a stopgap while you work on the underlying cause, not as the solution. And be honest with yourself about whether you have reached the point where somebody cannot safely be left alone at all, because that is a different conversation about the level of care rather than about door hardware.
