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

• Status: Recruiting
• Trial end date: 2021-09-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University at Buffalo
• Treatments: Lithium Carbonate; N-Methylaspartate
