I know my father has dementia which has included false memories/delusions and I think it's progressing.
Unfortunately, like most of them I guess, he doesn't think that it could possibly be his mind faltering.
It would be so much easier to care for him if he realized it's possbile his mind is playing tricks otherwise I fear it won't be too much longer before it's nursing home time and I'm sure I'll get negative comments for this but I'm not able to work in the workforce because of spinal problems that have me disabled. We've been helping each other out since he needs help (legally blind and almost deaf) while I've been trying to get my disability and/or find some source of income I could do from home.
If he ends up having to go to a nursing home before I can, I'll probably end up homeless since I'm sure that even nursing home costs even through the VA would take most of his money.
