DEAR LISTPEOPLE: Just a little note about Aricept. It is an acetylcholine enhancer and,theoretically at least, should make PD symptoms worse. However as we all know, everybody reacts differently to drugs. My Father-in-law has Alzheimer's (which Aricept is indicated for) and is holding his own with it, although it has caused him to lose his appetite. We counter this with Cyproheptadine (Periactin) to get his appetite back. Aricept can also cause nausia, which can be counteracted by taking it with meals or using natural Ginger (or Ginger Ale).
