Study Summary

Inflammation plays a central role in Parkinson's disease. The use of anti-inflammatory drugs was found to reduce the risk of PD . Niacin may play an important role in reducing inflammation in PD. The investigators also found that individuals with PD have a chronic niacin deficiency . The purposes of this study are to (1) examine the blood, urine and spinal fluid of persons with Parkinson's to look for evidence of inflammation and; (2) whether 6 months of vitamin B3 supplements may reduce the inflammation and/or improve symptoms.

Primary Outcome

This is the Unified Parkinson's disease rating scale assessment. The investigators assess I, II, III and V components of the UPDRS. UPDRS 3 is motor skills. Higher scores mean worse outcome. A 0 is minimum and 120 is the maximum.
