I was wondering if anyone knows if there could be a link between parkinsons and the use of any over-the-counter or prescription drugs. My husband has had a hevy reliance on both throughout his life and he developed his parkinsons after he used many anti-depressant drugs? If you don't know is there anywhere else I could get a good answer? I've tried MGH, but for some reason I've had trouble posting there. Thanks, Eileen Reilly
