A neighbor who i am getting to know better is a concern to me. This person is not married with no living relatives and no children. Recently learned that dementia is very common in the family. What kind of legal documents need to be written for the protection of his health and home and estate?
How old is he? It might not be a bad idea for him to check out assisted living places, to get an idea of what is available, and to discuss his wishes with close friends.
Even if dementia is "very common" in his family that does not mean he is likely to develop Alzheimer's. Hereditary risk depends on type of dementia, age of onset, and other factors. But in a sense, we are all likely to develop dementia if we live long enough. I understand that approximately 50% of people who reach age 80 develop dementia! And, of course, there are lots of other debilitating diseases that can strike as we age. So your friend is wise to plan ahead for the "what if" cases, but I hope he is not unduly pessimistic about his future just because many relatives had dementia.
You are kind to be concerned.
It is sad to be alone in the world.
Most of his surviving family are some distance
Just now developing trust in our frienship
There are persons who are skeptical when asked about their future
especially where estates, wealth and businesses are concerned
