It’s 2 a.m. and you hear the front door. Your mom, who has Alzheimer’s, is fully dressed and says she needs to get to work, a job she retired from twenty years ago. Or you wake to find Dad pacing the hallway, trying every door, convinced he has to “go home” even though he’s lived in this house for decades.
If this sounds familiar, you’re not alone, and it’s not something you did wrong. Dementia nighttime wandering is common, and it’s one of the main reasons families start looking for Alzheimer’s and dementia care at home. The good news is that there’s a lot you can do to lower the risk and keep your loved one safe.
This guide explains why people with dementia get restless at night, when wandering tends to start, which door alarms and home changes actually help, and what to do if your loved one does get out.
How common is wandering in dementia?
Very common. According to the Alzheimer’s Association, six in 10 people living with dementia will wander at least once, and many do so repeatedly (Alzheimer’s Association). Wandering can happen during the day, but night-time wandering is especially dangerous: it’s dark, the house is quiet, family members are asleep, and a person who leaves home may not be noticed for hours.
Wandering isn’t aimless, even when it looks that way. Usually the person is trying to meet a need, like finding a bathroom, getting to a job or a place from their past, looking for someone, or escaping a feeling of being uncomfortable or unsafe. Understanding the need behind it is the first step to preventing it.
What stage of dementia is wandering?
Wandering can happen at any stage of dementia, but it most often shows up in the middle stage. The Alzheimer’s Association lists wandering and getting lost, along with sleeping during the day and being restless at night, among the common changes of the middle (moderate) stage, which is typically the longest stage of the disease and can last for many years (Alzheimer’s Association).
That’s why it’s worth preparing early. If your loved one has been diagnosed but hasn’t wandered yet, now is a good time to put safety measures in place, before the first scary night.
Warning signs that wandering may be coming include:
- Saying they want to “go home” while they’re already at home
- Talking about going to work or fulfilling former obligations
- Pacing, restless movement or repetitive motions
- Trouble finding familiar places, like the bathroom or bedroom
- Getting lost in a familiar store or neighborhood
- Seeming anxious or agitated in busy or noisy places
Why are people with dementia restless at night?
Night-time restlessness has several overlapping causes. Many people with dementia experience sundowning, a pattern of increased restlessness, agitation, irritability and confusion that begins or worsens as daylight fades (National Institute on Aging). If your loved one’s evenings are a struggle, our guide to sundowning causes and tips for families goes deeper into what helps.
Other common contributors include:
- A mixed-up body clock. Dementia can disrupt the brain’s sense of day and night, so the person may sleep during the day and be wide awake at night.
- Too much daytime napping or too little activity during the day.
- Unmet physical needs: needing the bathroom, hunger, thirst, pain, constipation, or being too hot or cold.
- Low light and shadows that are confusing or frightening in the dark.
- Dreams that are hard to separate from reality on waking.
- Changes in routine or surroundings, such as a hospital stay, new caregiver or visit to a relative’s home.
- Medications or a new illness. A sudden change in behavior is worth a call to the doctor, since infections and medication side effects can cause confusion.
Nights getting unsafe? Let’s talk about care that keeps your loved one safe at home.
How to stop wandering at night
There’s no single fix, but a combination of daytime habits, evening routines and home safety changes makes a big difference for most families.
During the day
- Keep a steady routine. Meals, activities and bedtime at roughly the same time each day.
- Get outside and get moving. Daylight and physical activity help reset the body clock and make it easier to sleep at night.
- Limit long or late naps. A short rest is fine; a three-hour nap at 4 p.m. often means a long night.
- Plan meaningful activity. Folding laundry, looking at photos, gardening or a walk can ease the restlessness that leads to wandering.
In the evening
- Cut back on caffeine and alcohol later in the day.
- Reduce fluids before bed. The Alzheimer’s Association suggests limiting (not eliminating) liquids up to two hours before bedtime, and making sure the person uses the bathroom before going to sleep (Alzheimer’s Association).
- Wind down calmly. Soft music, a familiar TV show, a warm drink without caffeine, or a hand massage.
- Keep the bedroom comfortable and familiar, with a favorite blanket and photos.
If they wake up
- Stay calm and speak softly. Arguing or correcting usually increases agitation.
- Check for a simple need first: the bathroom, a drink, pain, or feeling cold.
- Reassure rather than reason. “You’re safe. It’s still night. Let’s get you back to bed” works better than explaining what year it is.
- If they need to walk, walk with them for a few minutes, then guide them back to bed.
Dementia door alarms and home safety changes
Home changes are your safety net for the nights when prevention doesn’t work. The Alzheimer’s Association recommends a number of practical options (Alzheimer’s Association):
- Door chimes and alarms. Simple chimes or monitors alert you when an outside door opens. Many families start here.
- Pressure-sensitive mats. Placed by the bed or front door, they sound an alert when stepped on.
- Deadbolts placed high or low on exterior doors, out of the usual line of sight.
- Door knob covers that make doors harder to open.
- Camouflaged doors. A curtain or a door painted the same color as the wall can make an exit less noticeable. Some people with dementia won’t step over a black mat placed in front of a door.
- Night lights in hallways and bathrooms so the person can find their way and isn’t frightened by dark rooms.
One important caution: never lock a person with dementia in the home alone or in a room. It’s dangerous in a fire or emergency. The goal is to slow down an exit and alert you, not to trap anyone.
It also helps to secure car keys, put away items that might trigger leaving (like a coat and purse by the door), and make sure your loved one wears an ID bracelet or carries identification with your phone number.
What to do if your loved one goes missing
Even with the best precautions, it can happen. Have a plan ready. The Alzheimer’s Association notes that many people who wander are found within 1.5 miles of where they started, often heading in the direction of their dominant hand, and advises calling 911 if the person isn’t found within 15 minutes (Alzheimer’s Association).
- Search the house and yard first, including closets, garages, sheds and cars.
- Check nearby places they’re drawn to: a former home, workplace, church or favorite store.
- If you don’t find them within 15 minutes, call 911 and tell them the person has dementia.
- Keep a recent photo and a list of medical conditions and medications ready to share.
- Let neighbors know ahead of time that your loved one has dementia, so they’ll call you if they see them out alone.
When night-time wandering means it’s time for more help
Many families manage early wandering with alarms and routine changes. But if your loved one is getting up every night, has already left the house, or you’re sleeping with one ear open every night, the situation isn’t sustainable for anyone.
An overnight caregiver can stay awake while your loved one sleeps, gently redirect them back to bed, help with toileting, and alert you if anything changes. Our caregivers are Teepa Snow-trained in supporting people living with dementia, so they know how to calm and redirect without confrontation. We also focus on consistent caregivers, because a familiar face is far less alarming at 2 a.m. Our caregiver retention is 65%, five times higher than the industry average.
Many families start with a few nights a week and adjust as needs change, and you can follow along through our family portal.
Wandering often becomes less common as dementia progresses and mobility declines, but new needs take its place. If you’re also thinking further ahead, our guide to the last stage of Alzheimer’s before death explains what families can expect and how to keep a loved one comfortable.
