My mum is 72 and was diagnosed with alzheimers a couple of years ago. Unfortunately over the last couple of weeks she has started not to recognise my dad and is getting quite agitated with him and doesn't know why he is in her house. She is also telling him not to touch anything as it is all her dad's things and he wouldn't be happy. I don't know what on earth to do. My mum is still very mobile and sociable but cannot be left alone. My mum is constantly asking for my dad and saying how fantastic he is but doesn't accept that he is with her. I feel so sorry for dad but I don't know how they are going to get on in the same home with her feeling so agitated with him. Any advice at all please? I have said to dad that maybe we need to set-up their spare bedroom for him to sleep in. Thank you so much.
