B-12 May Help Parkinson's Patients

Low levels of B12 in early-stage Parkinson’s patients are linked to a more rapid decline in motor and cognitive abilities, according to new research. Researchers measured B12 levels in 680 newly diagnosed patients. Those with low levels were given the option to supplement with B12. Subjects were tracked for 2 years, during which time physical and cognitive evaluations and B12 assessments were done. The study found that symptoms developed more quickly in patients with lower B12 levels, unless they chose to supplement, in which case they progressed much more slowly. Results are encouraging, but experts say more research is needed.
