We have recently found out that my OH has AZ, so I have been reading everything I can find on the subject. There is a book called "Contented Dementia" by Oliver James, which I found very sensible, helpful and comforting. It describes a a system called Specialised Early Care for Alzheimers (SPECAL) which is being rolled out from the SPECAL Centre, Sheep street, Burford, OX18 4LS. If anyone has time to read it, or even part of it, I'm sure you will find it a revelation. All carers should read it, even (or especially) the ones who only pop in occasionally.
