One such thing is the Dopascan from Guilford Pharmaceuticals. I don't know if it has yet won FDA approval or not. For info, visit their website. It's well worth it. Their web address is: http://www.guilfordpharm.com/products/dopascan.h >> Thanks Barb for this interesting website. I am happy to see that there may soon be a test to diagnose PD at its earliest stages. Kathy
