The Garage Is Becoming an Exit. Catch the Change Before Dusk.
A few small changes around the garage can tell you that Mom has found another way out, before that route becomes an emergency.
You have been watching the front door. Mom has been watching the door into the garage.
That shift can be easy to miss. She may open the garage door to look for something, move her purse closer to the car, or ask whether it is time to leave. None of this means she is being difficult. She may be following an old routine, looking for home, or trying to complete a responsibility that still feels unfinished. Those are recognized signs that someone may be at risk of leaving and becoming lost, according to the guidance collected on the Mom Wanders source list.
Notice the route before you change it
For several evenings, watch what happens between the room where Mom spends late afternoon and the garage. Do not wait beside the door or quiz her. Keep doing what you normally do and note the first three things she touches.
She may pick up her handbag, look for keys, check a coat, open the interior garage door, press the overhead-door control, or walk toward the car. The important clue is the order. That order shows you the route she is building in her mind.
Also notice what begins the trip. Does she hear a neighbor's garage door? Does someone mention work, an appointment, church, school, or going home? Does the kitchen become busy while everyone assumes she is in the next room? Guidance from the Alzheimer's Association says that former obligations, restlessness, confusion about familiar places, and wanting to go home while already home can signal a risk of wandering. It also advises families to identify the time of day when leaving is most likely. The supporting pages are listed in Sources.
Check every way the garage can open
Stand where Mom stands and test the route yourself. Check the door from the house, the overhead-door button, each remote control, any wall keypad, and the release that lets the overhead door move without power. Then check whether a side door leads from the garage to the yard, driveway, or alley.
Do not assume that moving one remote solves the problem. There may be another clipped to a visor, resting in a drawer, built into the car, or carried by someone who visits. Write down every control and who has it.
If Mom no longer drives, decide where the car keys will stay and who needs access to them. The Alzheimer's Association specifically advises removing access to car keys when a person no longer drives because leaving may happen by car as well as on foot. Its home safety checklist also recommends considering a motion sensor on the garage door. Both recommendations appear in the nonprofit guidance collected on the source page.
Look for the early failure, not just an open door
Your plan is beginning to fail if Mom can complete one more step than she could before. Last week she only asked for the keys. Now she finds the key drawer. Yesterday she opened the interior door. Tonight she reaches the overhead-door button. You do not need to wait for her to reach the driveway before changing the plan.
Other warning signs are ordinary household workarounds. Someone leaves the interior door unlatched while carrying groceries. A remote returns to the visor after a repair visit. The side door is propped open for the dog. A family member assumes the garage is safe because the car is gone. These are the moments to correct, because each one quietly restores the route.
Build a plan that works when hands are full
Choose one person to close the garage route before Mom's usual leaving window. Give that person a short check: keys put away, remotes accounted for, side door closed, overhead door down, and alert working. Put the check where that person will actually see it.
Then test the plan during the busiest part of the evening. Carry in groceries. Let the dog out. Take a trash bag to the garage. Have another adult arrive through the usual entrance. If the plan depends on everyone remembering a special step while distracted, simplify it.
Any alert must reach a person who can respond. Test it from the rooms where you cook, shower, sleep, and watch television. Test it with the normal household noise running. If it sends a notice to a phone, check whose phone, whether that person is present, and what happens when the phone is muted or charging elsewhere.
Keep an emergency exit possible
Do not create a setup that leaves Mom locked inside without help. Alzheimer's Association guidance warns against locking a person with dementia in the home. Any change should still allow the household to get out quickly during smoke, fire, or another emergency. Ask your local fire department to help you identify a safe exit arrangement if you are unsure how a proposed lock or garage change would affect escape.
Keep an accessible way for a responsible adult to open each exit. Make sure every person covering the evening knows where it is and can use it without searching through messages or calling you.
Know when the garage clue changes the evening
If Mom begins opening the garage route, finding hidden controls, trying several exits, or reaching the driveway, treat that as a change in what she can do, not a one-time surprise. The house plan and the supervision plan now need another look.
For tonight, stay close enough to notice movement toward the garage and give her somewhere else to go with you. Offer one clear next step, such as folding towels at the table or walking with you to another room. Do not argue about whether she owns the car, has work tomorrow, or is already home. A calm answer and a simple shared task can help you move away from the door without turning the doorway into a contest.
If you cannot find her, do not spend extra time proving which exit she used. Begin the missing-person steps in Start Here: Dusk to Morning, in Order.
