Convincing someone with dementia to use something is a tough one. The walker is really important, so the OT will have to work with her on that, and see if there’s some “carryover,” which means if the OT can get her to understand how to use it. The alert necklace, though? In all honesty, people with dementia don’t do well with those, because they just don’t know to press them when they need help. I wouldn’t worry about the alert necklace.
