My OH was diagnosed 6 years ago, but has only recently started to behave 'differently'. Some days he's his old self, completely aware, easily remembering things and some days he talks nonsense, can't make himself understood, can't see/find things etc.etc. I feel I need some guidance and always look for a book to refer to. Some of the Alz Soc booklets are OK, but some really aren't relevant. I have 'Contented Dementia' which largely seems to cover people who are iller than my OH, so I wonder if anyone has any sort of book which they find helpful as a reference. I try to be very patient but I never know how to behave when he's bad - sometimes we both make a joke of it, which seems fine, but I don't know if that's best for him. Any ideas most gratefully received !
