I am 60 years old and a Stage I PD diagosed last fall. I'm taking nothing at present. Living close to NIH, I volunteered for a study and appeared to have but accepted (paperwork in the mill.) The study is 22 months and involves a Smith Kline drug which is supposed to be a free radical scavenger -- free radicals being brain cell destroyers, I am told. The study involves weekly blood tests and 2-3 spinal taps. It will be the usual double blind test so half the participants will be on placebos. Question: is it sensible for me to be participating in such a test? How much is known about PD and free radicals? ------------------------------------------------------------- [log in to unmask] Victor K Heyman Heyman Mailing Service 5609 Fishers Lane #3B Rockville, MD 20852 -------------------------------------------------------------
