My mum has alzheimers and was prescribed Aricept 2 weeks ago and things have gone downhill fast since. She seems fine (well mostly) during the day but its when it comes to the evening - she says she doesn't live at her house and insists we take her home. To get round this we tell her that she must stop there that night as the home carers are coming in the morning - she usually accepts this. But not tonight - she got quiet aggressive and said why hadn't I told her she was stopping there and why did I lie to her. I then tried to convince her that it was her house but she wouldn't accept it at all - she then told me to go away and that I'd really upset her. I had to leave her cause she was getting really upset. I just don't know what to do to convince her that its her house - any advice welcome
