GREATER levels of vitamin D have been linked to a lower risk of Parkinson's disease in a study in Finland where low sunlight leads to a chronic lack of the nutrient, researchers said Monday.
Scientists from the National Institute for Health and Welfare, Helsinki, Finland, first hypothesised that Parkinson's "may be caused by a continuously inadequate vitamin D status leading to a chronic loss of dopaminergic neurons in the brain."
