I need some advice about my father in law who has recently been diagnosed with alzheimer's. The main concern at the moment is he thinks his wife has left him and isn't sure who the woman living with him is? Can anyone advise on the best way to handle this? It is very distressing for the family and mainly for his wife. The other concern at the moment is that he and his wife have recently written a will however as he thinks his wife has left him he is refusing to sign it. He is very confused about money in general; can power of atorney be given to his wife without causing him massives of distress? He doesn't want to lose control over his finances.
