Don: I wrote about our experiences with aricept in response to several notes that had been posted asking for people's experience using this new drug for Parkinson's patients who also have dementia. The drug was developed for early Alzeimers patients and increases acetylcholine which is often in too much supply in Parkinsons patients. But--- sometimes PWP do not follow all the same patterns, and I guess my husband is one of those. Anyway, I wanted to tell you how much Aricept seems to be helping us. I hope clears up your questions. Barbara Smith cgKen69/16
