It happens more often than most families expect. A daughter steps into the kitchen to make lunch. A husband falls asleep on the sofa. And when they look up, their loved one is gone.
Wandering — leaving the home or a care setting without supervision or awareness of the danger — affects an estimated 6 in 10 people with dementia at some point during the course of the disease. It is one of the most frightening things a family can experience, and in Florida, where summer temperatures can reach dangerous levels within minutes and many neighbourhoods sit alongside busy roads or bodies of water, the stakes are especially high.
This guide explains why wandering happens, how to recognise the warning signs before an incident occurs, what you can do to prevent it, and what to do if your loved one does go missing.
Why Do People with Dementia Wander?
Understanding why wandering happens is the first step to preventing it. It is almost never random. People with dementia wander for reasons that make complete sense to them in the moment — it is only from the outside that the behaviour looks dangerous or purposeless.
Common triggers include:
- Searching for something familiar. A person may be trying to “go home” — even when they are already at home — because they are mentally living in an earlier time period. They may be looking for a parent who died decades ago, or trying to get to a job they held years before.
- Restlessness and anxiety. Dementia can cause a constant underlying sense of agitation. Walking feels soothing. When the person cannot explain their distress, they may simply start moving.
- Responding to a hallucination or delusion. Some people with dementia see or hear things that seem completely real to them and act accordingly — following a person who is not there, or fleeing from a perceived threat.
- Boredom or unmet needs. Hunger, thirst, a need to use the bathroom, or simply a need for stimulation can all trigger wandering behaviour when the person can no longer communicate those needs clearly.
- Old routines. A former farmer who used to check fields at dawn, a teacher who used to leave at 7:30am, a parent who used to pick children up from school — muscle memory from a lifetime of routine can set a person in motion even when the context no longer exists.
The Difference Between Wandering and Elopement
These two terms are sometimes used interchangeably, but they describe slightly different situations. Wandering typically refers to restless, repetitive movement within a space — pacing the hallway, walking in circles, moving from room to room. It is concerning from a safety perspective but does not necessarily mean the person has left.
Elopement refers specifically to leaving a supervised space — the home, a care facility, a yard — without the knowledge of a caregiver. Elopement is the more dangerous of the two, and it is elopement that most families are referring to when they talk about “wandering.”
Both behaviours tend to increase as dementia progresses, though elopement can sometimes occur even in the relatively early stages — particularly if the person retains enough physical ability to act quickly and quietly.
Warning Signs That Wandering May Be Coming
Wandering rarely appears without warning. If you notice any of the following, it is worth taking preventive steps before an incident occurs:
- Repeatedly asking to “go home” or to go somewhere specific
- Increased pacing, restlessness, or agitation — especially in the late afternoon (a pattern sometimes called sundowning)
- Trying doors and windows, or repeatedly checking what is outside
- Becoming disoriented in familiar places, such as getting lost on the way to the bathroom at night
- Talking about old responsibilities or routines — “I need to get to work,” “The children will be home soon”
- Previous incidents of leaving the home, even brief ones that were easily resolved
How to Prevent Wandering: Practical Steps
Secure your exits
Door alarms are the single most important prevention tool. A simple chime that sounds when an exterior door opens gives you time to respond before your loved one gets far. You can find these at any home improvement store for under $20 per door.
Adding a second lock high on the door — well above eye level — is surprisingly effective. Many people with dementia will look at the standard handle height and not think to look up. Door handle covers that require a pinch-and-twist motion add another layer.
A black mat placed in front of exterior doors can act as a visual “stop” cue — the dark rectangle reads as a hole or a step to many people with dementia, and they will not step onto it. This sounds counterintuitive but is supported by care home research and is widely used in memory care facilities.
Address the trigger, not just the behaviour
If your loved one wanders at a consistent time of day, ask what is happening at that moment. Are they hungry? Bored? Anxious because they associate that time with a former routine? Solving the underlying trigger — a snack, a walk together, a structured activity — is often more effective than additional locks.
If the wandering is connected to a desire to “go home,” do not argue or try to convince them they are already home. Instead, redirect: “Let’s have a cup of tea first.” Validation and gentle redirection almost always work better than confrontation.
Build in regular supervised movement
People who are physically active during the day wander less at night. A daily walk, even a short one, can reduce restlessness significantly. If your loved one is a pacer, create a safe indoor loop they can walk — a clear circular path through the living room and hallway, for example, that allows them to move freely without approaching exits.
Register with the MedicAlert Safe Return programme
The Alzheimer’s Association’s MedicAlert + Alzheimer’s Association Safe Return programme provides an ID bracelet or necklace engraved with a hotline number. If your loved one is found by a stranger or emergency services, that number connects to a 24-hour response centre that can identify your loved one and contact you immediately. In Florida, the Silver Alert system performs a similar function — you can register your loved one’s information in advance with local law enforcement so they are already in the system if you ever need to call.
Consider a GPS tracker
Wearable GPS devices designed for people with dementia can be worn as a watch, clipped to clothing, or placed in a shoe. If your loved one does leave, you can locate them quickly. Some devices also have geofencing — they alert you when the person moves outside a defined area, before they have gone far.
Tell your neighbours
This is one of the simplest and most underused prevention tools. Let two or three nearby neighbours know that your loved one has dementia and may sometimes become confused outdoors. Give them your phone number. Most neighbours are willing to help — they just need to know what to look for and who to call.
Florida-Specific Risks
Heat and sun exposure
Florida summers are brutal. An older adult with dementia who has been outside for 20 to 30 minutes in direct sun can be in serious danger of heat stroke — especially if they are taking medications that affect temperature regulation (which many dementia medications do). If your loved one goes missing in summer, treat it as a medical emergency and call 911 immediately, not after searching yourself for an hour.
Pools and water
Florida has more residential pools per capita than almost anywhere in the United States. Drowning is a real risk for wandering adults with dementia, who may be drawn to the water without understanding the danger. Ensure your pool has a self-latching gate with the latch above shoulder height, and consider a pool surface alarm in addition to the gate alarm. The screened enclosure is not a barrier — a person with dementia can open a screened door.
Traffic and road proximity
Many Florida communities are laid out around arterial roads with fast-moving traffic and no footpaths. A person with dementia who leaves a home in one of these communities and walks toward the road is in immediate danger. Know the exits from your property and the hazards within walking distance. This knowledge is essential if you ever have to search.
If Your Loved One Goes Missing: What to Do
Stay as calm as you can — panic makes it harder to think clearly and harder to communicate with emergency services.
- Search the immediate area first. Check every room, including closets, bathrooms, and outdoor spaces including the garage. Call their name calmly. Check the backyard, the front of the house, and anywhere they have gone before.
- Call 911 immediately if you cannot find them within a few minutes. Do not wait. In Florida’s heat especially, a few minutes matter. Tell the operator that your loved one has dementia — this activates a Silver Alert if appropriate. Provide a recent photo and a description of what they were wearing.
- Contact your neighbours. While you are on the phone with 911, have someone else alert the nearest neighbours to look and listen.
- Think about where they might go. Former home addresses, workplaces, the home of a deceased parent or spouse, a church or community centre they attended for years — people with dementia often head somewhere that was significant earlier in their life. Give these locations to law enforcement.
- Activate GPS tracking if they are wearing a device.
When Prevention Becomes Too Much to Manage Alone
If wandering is a consistent concern — if you find yourself unable to sleep properly, afraid to step away for even a few minutes, or exhausted from vigilance — that is a sign that the current level of care has exceeded what one person can safely provide alone. This is not a failure. It is a recognition that dementia care, at a certain point, requires more than one set of eyes.
A trained in-home dementia companion provides consistent, professional supervision during the hours they are present. They are experienced in de-escalating wandering behaviour, redirecting restlessness, and spotting the early warning signs that an attempt is likely. Their presence also gives you the ability to rest, work, or simply step outside without fear.
