I have always wondered that myself. According to my someone I asked that question of before, supposedly no one's ever been cured of PD. I hear of miracle healings from MS, and other neurological types disease, why not PD? Well, since this PD list has so many subscribers, if there's someone out there, hopefully we'll hear about them! I have heard of people living with it 20-30 years or more with little progression, that may not be a miracle cure, but I'd take it any way. wendy tebay
