I have got an 86-year-old father who is an amputee and has dementia. He does not eat a lot, is extremely hard of hearing, and he often fights other people who try to help him in any way (like feeding him). He pushes and shoves hands and things away from him and has recently taken to swiping at people and slapping their hands, etc. When I was trying to help feed him a few days ago he literally grabbed my arm in such and angry and aggressive way. He would not let go until I called for my husband (I guess he's afraid of my husband but not me). This is such a dramatic change in his personality. I sometimes can't bear being around him and I am actually afraid to touch him now. What is wrong with him? He is on medication to calm him when he is agitated, and he gets agitated OFTEN. I have already discussed this with various homes that he has been in numerous times, and they do give him meds to calm him down. It was never my first choice, but I relented because the homes have told me that he can be a danger to himself and others, so I let them medicate him as needed. Is he near the end of life because of this increasingly bizarre behavior? Has he lost his mind? I asked the day he grabbed my arm if he knew me and he said yes and said my name, so apparently he does recognize me and my husband.
