Parkinson’s Disease & Movement Disorders Clinical Trials

EvergreenHealth Research is part of a large PD consortium through the National Institutes of Health.

Parkinson Study Group:  The largest not-for-profit scientific network of credentialed Parkinson Centers comprised of experienced investigators and coordinators from academic/research institutions in North America. Research is conducted to find new treatment for PD, as well as new ways to diagnose PD and related neurological disorders. PSG trial sites are selected on the basis of their experience and performance in conducting clinical research studies in Parkinson's disease.
