My mom with dementia tries to leave the

Tonight, take the key-only deadbolt off the door she uses and swap "locked" for "alarmed" — every exit she can reach must open from the inside in the dark, with one hand and no key, and the goal is to know she is at the door within seconds, not to keep her locked in it.

A key-only lock is the one arrangement that makes the worst night worse: if there is a fire, or she needs out for any other reason, she cannot get out — and a frightened person pulling at a locked door is exactly when a caregiver gets hurt. The levers that work are alerting, light, routine and identification.

1) What you tried vs. better alternatives

Key-only deadbolt → an alarmed door instead of a locked one. Keep the door mechanically openable from inside: one twist or one pull, no key, no combination, no chain, no sliding bolt she has to work out. Add the "she is at the door" signal — a contact sensor with a receiver that reaches where you sleep, or an alarmed door bar. She gets the same warning sound, you get a head start, and nothing is locked behind her.

Door chime (you have one) → make sure it reaches your bed. Test the volume from the pillow tonight. If it only sounds in the kitchen, add a receiver or a sensor-notification that pings a phone in the room where you sleep, and cover the other exits she might use: back door, garage, laundry, any window or balcony door. One alert point per exit is enough.

Dark hallway → motion night-light. A light that comes on by itself when she gets up removes the disorientation that often starts the attempt, and lets you see her without a bright lamp that wakes her fully.

Nothing yet for *why* she leaves → the bathroom, before bed. Most night attempts are a toilet trip or a feeling of "I need to go somewhere". Take her to the bathroom around 8–9pm, keep a night-light in the bathroom, and leave that door unlocked and visible. Then the same small ritual every night: a warm drink from the kettle (no stove at night), lights low, ten minutes of something familiar — a photo album, folding towels, a favourite show — then bed.

Nothing yet if she does get out → ID and neighbours. A card in her coat and wallet with her name and one family phone number, plus a note in the coat pocket: "My mother has memory problems. Please call [name] at [number]. She is safe — please help her home." Tell two neighbours on her usual route: call me, don't chase her, don't try to bring her back yourself.

The stove and the car are two quiet risks. If she turns the oven on at night, an automatic shut-off timer is the fix. If she still drives, the car keys are the single biggest lever in the house — and it is a conversation her doctor can support.

2) Tonight and tomorrow, about 25 minutes

If you can only do three things tonight: make every exit open from inside without a key; make sure the alarm wakes you; put the ID card in her coat.

Tonight (20 min)

1. Egress test (5 min). Walk each exterior door in the dark with your hands full and open it from inside. If it takes a key, more than one motion, or both hands, fix it tonight. Put the house key on the night person's body — pocket or lanyard — not in a drawer.
2. Signal (5 min). Fit or move the alarm so it reaches the bedroom; test it from the bed, not from the kitchen.
3. Light (3 min). Motion night-light in the hall, bedroom and bathroom. No candles, no space heater by the bed.
4. Fire check (4 min). A working smoke alarm on each level; nobody sleeps with the stove on.
5. Ritual and log (3 min). Bathroom trip before bed, then the warm drink and the familiar activity. On a sheet on the fridge write: date, time she went to the door, time she came back, what helped. Two lines a night is enough.

Tomorrow (15 min, no medicine changes at home)

1. One call or message to her memory clinic or family doctor with the three questions below.
2. Night cover: agree which nights the sibling or the one relative takes. If you are alone with her, she is agitated at 2am, and you are exhausted, call someone instead of handling it alone.

3) What to avoid

• Do not lock, bar, chain or padlock any exit she can reach from inside, and never padlock a door from the inside.
• Do not block the doorway with furniture or a heavy planter — it obstructs escape and she will try to climb it.
• Do not lock a room she needs (bathroom, her bedroom, a room with a window), and do not hide an exit she might need in a fire.
• Do not chase or grab her if she is outside. Follow at a distance, one calm voice, one other person nearby to intercept calmly. A chase escalates and ends in falls.
• Do not restrain her, and do not use sedating or "calming" medicine, supplements, or anything bought online to keep her in bed. Medicine decisions belong to her clinician; a review is something you request, not something you do.
• Do not argue with her facts, shame her, or tell her she is being locked up. Use one simple true sentence and redirect.
• Do not accept "she is more confused tonight" as "just the dementia" — see the red flags below.

4) Decision tree for the night

The alarm goes off / she is at the door
→ Go within a minute. Light on. Open the door a hand's width, warm and calm; don't stand blocking the frame.
→ Offer the two things that work most often: the bathroom, or a warm drink.
→ If she insists on going out, offer to go out with her — porch, yard, around the block for a few minutes, then back in for the snack. Do not argue at the door.

She gets outside
→ Do not chase. One person goes with her; one person calls a neighbour and another family member.
→ If she is in a car, near traffic or water, in the cold or the heat, has fallen, or is not answering you: call your local emergency number now.
→ Have the coat note and ID card ready; if she is lost, the neighbours and the note do the work for you.

You were asleep and the door was open when you woke
→ Treat it as an alert gap, not a discipline problem: the notification has to reach the bed, and put a second adult on nights after that.

She seems more confused than usual tonight, or newly agitated
→ Stop the DIY work and use the red flags below.

She falls, hits her head, or cannot get up
→ Call your local emergency number now. Do not lift her by the arms, do not let her walk it off, and note how long she was on the floor.

5) Red flags: when to stop DIY and get help

Call your local emergency number now if: confusion comes on suddenly or over hours and she is hard to rouse or cannot be woken; one side of her face or body is weak or droopy, or her speech is slurred; she has a fit; she has chest pain or new breathlessness; she has fallen and hit her head, or has spent any time on the floor; she cannot pass urine; or she is found outside in traffic, in the cold, or in the heat.

Same-day clinician, do not wait for the next appointment if: she is more confused than usual or "not herself" over hours or days, even without a fever; the night restlessness is new or suddenly worse; she has burning urination, cloudy urine, a fever or new incontinence; she is eating or drinking much less or passing very little urine; she has constipation with a swollen belly; she falls without a head knock; or any medicine was started, stopped or changed in the past month. New confusion can come from infection, dehydration, constipation, pain or a medicine change — it is a symptom to be looked at, not a stage to accept.

Raise with her memory clinic (book it, don't panic): the pattern of the walking-out, how far she gets, how often it happens, her night sleep, whether she has been found outside, safety at home (stove, driving), and a request for a review of her whole medicine list.

I cannot diagnose anything and I will not change or suggest a medicine. The medication review is a request for her clinician, and every medicine decision stays with them.

6) What success looks like in 24 hours

Not a cure — a safer night:

• Every exit opens from inside without a key, verified by your own test.
• You hear the door attempt within about a minute, from your bed.
• One bathroom trip before bed and the warm-drink ritual happened on schedule; the fridge log has the time of each attempt.
• ID card in her coat; two neighbours briefed.
• One question sent to her clinic asking for a medication review and about night safety.
• Zero nights where an exit was locked.

Scripts you can screenshot

To her: "It's the middle of the night, and it's dark and cold outside. I'm right here. Do you need the toilet? Would you like a warm drink? I'll sit with you."

To a neighbour: "Hi, this is [your name] at [address]. My mother has memory problems and sometimes walks out at night. If you see her, please call me at [number] and don't try to bring her back yourself — she may be frightened."

To her doctor or memory clinic: "She tries to leave the house at night, usually around [time]. We've added a door alarm and a night-light and kept every exit openable from inside. What would you add? Could you review her medicines as a whole? Is there a local service for families dealing with walking out at night?"

To a family member: "Can you take [day] night? I'll take [day]. If you can't, tell me by 6pm so I can plan."

One question so I can sharpen this: has she actually gotten out and been found somewhere unsafe — a street, a car, out in the cold — or so far she only reaches the door?

Tell me your country and city and I'll look up the local dementia and wandering support and the official service doors for your area. I've also made a one-page version of this (checklist plus decision tree) you can print or screenshot: night-exits-onepager-2026-10-25-19e80775.pdf
