Don I am sorry to learn of your friend's diagnosis of ALS. My uncle died of this within a year once he was dx. His brother had MS as well as his own daughter has MS. I can understand why you feel fortunate to have PD and not ALS. Many of my online friends do have PD, and I know their suffering. What ever the differences are between these neurological diseases, when the cure or prevention for one is isolated, it may unlock the cure for the others, including Parkinson's.
