One area studying stats such as this is where a surveillance registry would be very useful. The Parkinson's Action Network (PAN) needs every constituent, regardless of which party you support, to contact your legislators about Data collection through this action:

Also, August recess is an excellent time to pay a personal visit to your local representatives home offices about any or all of these PAN initiatives:

What are you waiting for? Having you personally visit with legislators is of paramount importance - SEEING IS BELIEVING!
