Jeremy, I "don't" know ....but I would like to add that there are several members from the Dystonia group that "wonder" if their Dystonia is a precurser to PD.... I've noted just from their conversations that one of the "reasons" they are concerned about this is because they have family members <moms,dads, grandparents, ect> that have a dx of Parkinson's Diesease.... From what I've "read" in medical journals, heard from "list"... PD isn't thought to be heritary <sp?> but my "gut" feeling is that there is a relationship somehow (other than the markers on chromosome #9). Just my 2cents....Elf in Tn...Romona <mom to Tori, Cory and Zach , the boys have several labels "no" definative Dx...
