I have been awake since 3.30a.m. worrying about my husband's increasingly difficult behaviour. His parents had Alzhheimers and it has occurred to me previously that he may be showing signs. However he has become very difficult lately - mood swings and unreasonable behaviour. Becomes angry and screams and shouts at the slightest remark. He has forgotten some surprising (was looking at a picture on our wall of a place we know very well and had no idea where it was) and seems to be slowing down in his thinking. Used to read a lot but doesn't now. Chooses to watch really unchallenging TV . He used to be interested in politics but is now more likely to talk about pop culture. He has become really thoughtless but I don't think he can help it. Feel he needs help but extremely difficult to approach him on any subject. My mother is in a nursing home with vascular dementia. I am trying very hard to keep myself positive. Not sure how to get support or what next ???
