Do you or a loved one have Parkinson's disease or progressive supranuclear palsy?

The purpose of the study is to improve the diagnosis and treatment of parkinsonism, and to help discover the differences in proteins in your body fluids that are unique to Parkinson's and PSP.

Adults over the age of 40 may be eligible to participate if they have been diagnosed with progressive supranuclear palsy or have been diagnosed with Parkinson's disease. Participation requires three visits over two years with modest compensation for your time, including free parking and lunch provided.
