No results posted yet for this study

Summary

Retrospective review of records in the Emory Movement Disorders clinic suggests vitamin D deficiency occurs in over 80% of patients with Parkinson's Disease (PD), much more frequently than in internal medicine clinics. Laboratory studies have suggested vitamin D could play a role in the development of PD. In addition, low vitamin D levels have been associated with slower walking speeds, worse memory and thinking, and depression.
