Brief Summary: Based on Parkinsons disease PDvitamin B12 deficiency symptom overlap and PD patients propensity to avoid protein the dietary source of vitamin B12 this study proposes to prospectively investigate the vitamin B12 status of PD patients over time In addition this study will provide critical pilot data evaluating the efficacy of treating those patients considered to have below-normal vitamin B12 levels in serum Further it will also explore the concept that supplementing PD patients having low-normal vitamin B12 levels with vitamin B12 improves either the non-motor PD symptoms or homocysteine levels in PD patients receiving levodopa

Study Hypotheses

1 Serum cobalamin B12 concentrations in patients with Parkinsons disease PD are significantly lower than B12 concentrations in a cohabiting spousal caregiver controls and b population-based age-matched controls
2 Supplementation with B12 in levodopa-treated PD patients with low 200 pgml or low-normal 200-300 pgml serum B12 levels is associated with significant improvement in their non-motor symptoms and reduces total plasma homocysteine concentration Hcy a known biomarker for risk of dementia and cerebrovascular disease
