This sounds like very good news but I have always been skeptical of 
these animal studies. Inducing Parkinson's symptoms by damaging rat 
brains creates PD symptoms but not the actual disease process. PD is 
a progressive, degenerative disease. Do the rats in the "control" 
group" show the same sort of declines we humans do? It seems to me 
that  doctors and researchers are  resolutely plowing  the field of 
symptom relief while prevention and cure get short shrift.
