Dear Bill, Many thanks, on behalf of all of us who are both dealing with and trying to educate non-PD communities re Parkinson's, for sharing your wonderful reply to your Taiwanese communicant. You did a great job in reducing a lot of critical mateial to an explainable mode, succinctly and helpfully. It'll be very helpful for me, I know, to keep a copy of your explanations for future use in reply to similar inquiries. Best wishes, John Bachman Santa Fe, NM age 57 PD diagnosis 4 1/2 yrs ago first symptoms 8 yrs ago
