I'm reading the post and there's some myths to clear up. I've been on the board for over 2 years and seldom post anymore, but working with AD and having family with AD takes a lot for me to want to post. Some subjects provoke me to do so.
I want to address if the RX's work, they do most recent NIH (national institutes of health) published this week states Aricept works, works well. But also in these studies it warns and in others that taking someone off Aricept causes a decline and they never return to normal functionality. This is very true, so one should stay on it from diagnosis to death. According to Howard Feldman, MD the foremost expert on AD (more publications on AD and research / practice for 30 years than any other) in the world recommends this to all patients.
Combination therapy is advisable as well Aricept w/ Namenda is great as it works on two parts of the brain and maintains functionality. No drug claims the person gets better they maintain there abilities with slower decline. Understanding the drugs effects in simple terms is the meds boost the good chemicals that send signals through the brain and nervous system and block the bad chemicals.
in my opinion, some meds is better than none as moments slip just one moment for a little longer, folding the close, remembering my name, remembering my childs name or that of their great grand child is worth that little pill.
If you also want a good read it discusses the meds and AD care, it's short at 140 pages, Alzheimer's Essentials (Gordeau / Hillier)
Good luck and
