As some of you know, they have identified a GENETIC link to Parkinson's
Only a small percentage have it. Michael J Fox foundation & 23 & Me have a program to identify those with it.
What is remarkable to me is that ADD/ADHD, Tourettes, OCD, Restless leg, & PD are connected to this gene.
Here are some recent research they are doing.
