Hi Charlie, Hope you got my last note to you. Now the address on this post is supposed to go to the entire list, so I hope it does. It's very interesting to read about the ongoing research and this latest info from you is very helpful. Also, did you read the post from CARLTON (Linda Forrest's Mom) re deprenyl and the protective aspects found from a research study? My main concern has been with the taking of deprenyl along with sinemet but I guess that is being done on a regular basis. Next we'll seek more advice from neurologist to see if it would be in my husband's best interest to take it with his sinemet or not. Thanks again. Den
