Lack of vitamin D linked to Parkinson's disease


EurekAlert - A majority of Parkinson's disease patients had insufficient levels of vitamin D in a new study from Emory University School of Medicine.

The fraction of Parkinson's patients with vitamin D insufficiency, 55 percent, was significantly more than patients with Alzheimer's disease (41 percent) or healthy elderly people (36 percent).

The results are published in the October issue of Archives of Neurology.

The finding adds to evidence that low vitamin D is associated with Parkinson's, says first author Marian Evatt, MD, assistant professor of neurology at Emory
