As far as I know there currently isn't a good way to tell if a living patient has Alzheimers as opposed to more general dementia. Given that my mom has been showing signs of this for the past few months I'd be curious if anyone here actually knows more. I've found "The 36-Hour Day" http://www.amazon.com/36-Hour-Day-Alzheimer-Dementing-Illnesses/dp/0446610410 http://www.amazon.com/36-Hour-Day-Alzheimer-Dementing-Illnes... to be somewhat helpful so far. Anyone have any other good recommendations?
