Peggy,

Your latest post on this thread made me think of something. You wrote:

"figure out a formula that can predict how they would be say 2-3 years from now"

Next month I'm going back to Yale at the Instutute for Neurodegenerative Disorders for my 3rd SPECT scan using the B-cit isotope. (I'll have had brain scans in 2003 & 2005 & 2007) Scientists there hope to (eventually) get FDA approval for this scan procedure and hope to show that this scanning method can document the progression of PD.

Maybe some day scientists WILL come up with some kind of formula to predict the progression of PD. And MAYBE it will be due in part to the scans that I and fellow cep1347 participants had taken as part of clinical trials for the SPECT procedure. That's a very nice thought indeed.
