After two years now, finally diagnosed after a stroke 13 years ago. He can still have some normal conversations. No longer drives (used to be a salesman drove everywhere). Doesn't want to go anywhere, won't shower regularly, won't let anyone help him. Has poor eating habits, sleeps a lot (is that normal for dementia?). I know unless you look inside the brain it is hard to know what is going on in there and every case is different. I'm trying to navigate this. Never know what he will be like each day. Either he doesn't want to be bothered and sleeps all day or he is in a more social mood. I sometimes think he has given up, but then again if it's the disease and he can't really help it, I'm trying to adjust my reactions accordingly. Married 50 years.
