Clinical trial

Effects of Lithium Therapy on Blood-based Therapeutic Targets in Parkinson's Disease.

Name
STUDY00003688
Description
This study aims to determine if one of three low doses of lithium therapy for 6 months can engage one or more blood-based therapeutic targets implicated in Parkinson's disease (PD) pathophysiology. Results of this study will help to determine if lithium therapy is worthwhile to further investigate as a potential disease-modifying therapy in PD, the optimal dose to study and the optimal PD subgroup most likely to benefit from lithium therapy.
