How to Arrange a Safe Home Environment for Seniors with Alzheimer's? (Furniture Edition)

II. Key points for senior home safety protection

We found that many patients feel uneasy about dark floor tiles or mirrored surfaces. After replacing them with matte, tone-on-tone furniture, the tense wandering behavior of the elderly significantly decreased.

Compared to other seniors of the same age, Alzheimer's patients hit furniture significantly more often. This is not only because AD patients have a weaker ability to distinguish colors, but also because of errors in distance perception, leading to misjudgments of furniture proximity.

Therefore, furniture must have rounded edge treatments. If furniture with sharp angles is purchased, it must be wrapped with corner protection tools to avoid injury.

In addition, the use of lightweight small furniture is not recommended. AD patients will grab any object in their field of vision when losing their balance. Therefore, all side tables and dining chairs must have sufficient self-weight or base reinforcement and anti-slip bases. Some elderly people have been reinjured precisely because of lightweight plastic chairs or rolling storage cabinets.

Furthermore, cabinet doors should use magnetic suction or hidden switches instead of complex handles. Avoid using handles shaped like fruits or small animals; AD patients may experience hallucinations and mistake them for real objects.

III. Home space layout logic

Alzheimer's patients often get "lost" in their own homes, so they need better visual guidance.

The path from the bedroom to the toilet must be free of any clutter, and furniture placement should leave a wide aisle of at least 100cm to avoid tripping the elderly. Color-contrasting baseboards can be used for this aisle to form a "visual corridor," guiding the senior to their destination. Then, avoid dark floor mats to prevent AD patients from perceiving them as a "deep pit," which might cause them to fear going to the bathroom.

Install handrails by the bed, sofa, and toilet to avoid the risk of falling caused by a sudden rise in blood pressure after standing up quickly. Moreover, handrails should not be the same color as the wall or stainless steel; orange or yellow is the easiest for AD patients to identify. Use anti-slip and warm wood-imitation or silicone materials for handrails to avoid coldness in winter; this sense of warmth can bring a sense of security to the elderly.

Bedside induction ambient lights can be installed, which trigger automatically when the senior gets up at night, providing direction and avoiding the fear brought by darkness. However, there is a detail here: AD patients easily mistake the shadows of furniture for intruders. Therefore, in addition to the bed light, the lighting of the entire space should be as shadow-free as possible.

IV. Emotional care and anxiety management

As a family member of a patient, you can place easily identifiable daily items, such as old photo frames and frequently used cups, on open storage shelves so the senior can see them more easily. You can also put labels on them (such as "for drinking" or "for reading") to reduce the patient's cognitive pressure.

However, note the "less is more" principle: each shelf should only display 3-5 high-frequency items to keep the space "blank." The Dementia Services Development Centre (DSDC) at the University of Stirling has proposed the application of "visual transparency" and "reducing visual noise" in furniture design.

Furthermore, choose chairs with slightly firmer cushions and good support for them. A sofa that is too soft will cause the senior to sink into it, making it impossible to support themselves to stand up. Over time, this easily leads to muscle atrophy, making the elderly feel even more helpless.

For example, choose chairs with high armrests for patients. When the senior tries to get up, they can first grab the armrests to obtain a stable pivot point before exerting force to support themselves. Additionally, many AD patients fear sofas that are too deep or too soft because they feel as if they "sit in and can't get out."
