3. We need biomarkers for Parkinson's. Loss of sense of smell is one that most scientists agree on.

4. We need research on the many "types" or subgroups of Parkinson's. It's time for an open acknowledgement that PD is actually many diseases. And let's have current researchers / movement disorder specialists begin a database of the subgroups they have encountered. Share the data.

5. (Re: Peg's #2) We need to get FDA approval for DAT (dopamine transporters) imaging with SPECT (single photon emission computed tomography). This has been tested and found to identify parkinson's disease in people with early PD. I was one hundreds tested in the PRECEPT and PostCEPT trials (2003-2005). And there are other trials going on right now. So why isn't there a big push to complete the trials and to use it as an FDA approved diagnostic tool?
