Would AIDS research on the AIDS virus help uncover the answers to the "cause" of Parkinson's? Ivan >> Ivan, Amantadine was developed as an influenza antibiotic. It is certainly not a satisfactory anti PD antibiotic (if a virus causes PD). To my way of thinking, the therapeutic relationship tends to prove PD not to be an ongoing viral process. However, doesn't rule out a viral event initiating it. Regards, WHH 54/18
