Interesting boann. I remember the first time I heard this new "definition" of PD was 2 years ago. While I'm glad they are discovering new things about the illness, if it delays a treatment or leads researchers astray - well I think I'll lose faith in man. Dare I say, what little faith I have? What good is it to correct my depression if I can't move? Interesting thoughts. That's why I like to hang around places....so they can look at a real clump of dopamine deficient cells...lol
