Do the dusk safety walk-through yourself, or bring in a second set of eyes?

You do not need to remake the whole house tonight. You need to find the places where Mom slows down, turns the wrong way, reaches for something unsteady or sees an invitation to leave.

Begin shortly before the time she usually becomes restless. Turn on the lights as they would normally be used. Put on your usual shoes. Start where Mom tends to be, then walk her likely route to the bathroom, kitchen, bedroom and outside door. Government home-safety checklists recommend looking room by room because lighting, clutter, rugs, cords, stairs and loose rails can create different trouble in different places. (National Institute on Aging and Centers for Disease Control and Prevention home-safety checklists, listed in Sources.)

Do the first walk-through yourself

Carry paper and write down what you see. Do not rely on remembering it after a long evening. At each turn, ask four questions: Can she see where the path continues? Is anything underfoot? Is there something solid to hold? Does the route lead her toward what she is looking for?

Check the path from her chair to the bathroom. Move shoes, baskets, cords and small tables out of the walking line. Notice rugs that slide or lift at an edge. Check whether a light can be reached before she enters a dark hall. The CDC advises clear walking paths, secure or removed rugs, accessible lighting and sound handrails. (CDC fall-prevention guidance, listed in Sources.)

Now look from Mom's height and direction of travel. A bright window may make a darker hallway harder to read. A mirror may look like another person or another room. A dark mat may look like a step or a hole. The National Institute on Aging advises reviewing lighting, clutter, floor coverings and mirrors when making a home safer for someone with dementia. (National Institute on Aging dementia home-safety guidance, listed in Sources.)

Next, check the things she may handle when she is trying to complete a familiar task. Look at stove controls, cleaning supplies, medicines, tools and car keys. The Alzheimer's Association recommends paying particular attention to kitchens, garages, work areas, basements and outdoor spaces, where hazardous items may be within reach. (Alzheimer's Association home-safety guidance, listed in Sources.)

Make only the simple changes you can test immediately. Clear the route. Replace a failed bulb. Put a needed lamp within reach. Move a loose rug. Store a hazardous item where Mom will not encounter it. Then watch one ordinary evening. A change is useful only if she can still find the bathroom, reach her chair and move through the room without becoming more confused.

Know when your own checklist is enough

You can usually keep the walk-through in the family when the trouble is easy to see, the fix does not alter the structure of the house and Mom moves through the route much the same way each evening. One person should keep the written list, mark what was changed and note what happened afterward.

Recheck the route whenever her habits change. The National Institute on Aging notes that home safety should be reviewed again as a person's behavior and needs change. (National Institute on Aging home-safety checklist, listed in Sources.)

Bring in a second set of eyes when the problem is not the object

Hire or request a trained home-safety visit when you keep moving things but cannot explain why Mom hesitates, loses her way or nearly falls. Also get help when stairs, bathing, transfers between a chair and standing, or several rooms are involved. A trained visitor can watch how she actually approaches a turn, reaches for support and responds to signs or lighting. The CDC notes that an in-home review can reveal hazards that may be missed away from the house. (CDC home-modification and safety-assessment guidance, listed in Sources.)

This is not handing over the whole evening plan. You are buying another pair of eyes for a defined question. Ask Mom's regular care office, a local aging organization or the Alzheimer's Association what kind of home-safety visitor serves your area. The Alzheimer's Association notes that a therapist with dementia experience can offer strategies fitted to the person and family. (Alzheimer's Association safety-assessment guidance, listed in Sources.)

Ask these questions before you schedule

Say exactly what you need observed: "Mom becomes unsure between the living room and bathroom after dark," or, "She crosses the kitchen when she heads for the outside door." Ask whether the visitor will come during the late-day window, watch Mom use the route and leave written priorities.

Ask what happens after the visit. Who explains the recommendations? Which changes can you make yourself? Which require a qualified installer? Will the visitor return or review photographs after changes are made? Will the written plan separate urgent hazards from ideas that can wait?

Ask how the visitor works with Mom. You want someone who observes before rearranging, explains changes in ordinary language and avoids turning her familiar house into a puzzle overnight. Ask whether the person has worked in homes where someone with dementia becomes restless or tries to leave.

Compare recommendations by the problem they solve

Do not accept a list of products without a reason for each item. Beside every recommendation, write the moment it is meant to improve: seeing the bathroom entrance, crossing a rug edge, finding support on a stair, avoiding the basement or moving safely from bed to hall.

Then ask what new problem the change might create. A moved table can clear a path but remove a familiar landmark. A brighter light can reveal the hallway but create glare. A sign can help on one evening and be ignored on another. Test one change at a time when possible, and watch the route again under the same evening conditions.

Leave yourself one usable page

Your final page should name the route, the trouble spot, the change, who will handle it and what you will watch afterward. Put unfinished repairs on a separate list so they do not disappear into conversation. Keep emergency numbers and the home address where anyone covering the evening can find them, as recommended by national home-safety guidance. (National Institute on Aging and Alzheimer's Association checklists, listed in Sources.)

If the walk-through shows that the larger problem is supervision rather than the room itself, move to Start Here: Dusk to Morning, in Order. If you need a local organization that can help you find the right kind of visit, use Lifelines: Dementia Help in St. Louis.

You are not choosing between being capable and asking for help. You are deciding whether the house is showing you the answer. If it is, make the small fix and watch. If it is not, bring someone into the actual room, at the actual hour, and ask them to follow Mom's path.
