I only post on here when I have a problem, I don't mean to be ungrateful and do read all the replies which in the past have helped a lot. Mum has just come out of hospital after 4 weeks, she was taken in with severe dehydration, which I'm ashamed to say neither my Dad nor I noticed. We put it all down to AD. Anyway, she's home now and a lot better. When she was in hospital they increased her dose of Aricept from 1 a day to 2 a day. This seems to have made an improvement. Anybody else heard of this or are are my Dad and I imagining things? Thanks again.
