Dear Jason, As to your question concerning why so many "young" people have Parkinson's, there is probably a more obvious,less shared answer. What no one ever talks about in this group is the past use of recreational drugs. We know that Cocaine may be a major contributor to early onset Parkinsons. Other recreational drug use, such as LSD,marijuana, and speed may also be at fault. The group of people entering middle age now were the 60's generation. While it is more acceptable to talk about insecticides, herbicides, fungicides, and vitamins as insidious causes of this disease, substance abuse should be explored as well. ----- Mary Ann Ryan
