UC-Davis Study Finds Link Between Low Vitamin D, Increased Dementia Risk

A UC-Davis study published in JAMA Neurology finds that low vitamin D levels among seniors could increase risk of dementia. The study, which examined 400 seniors over five years, found cognitive brain function and memory loss among seniors with insufficient vitamin D levels deteriorated more than two times as fast as those with normal vitamin D levels.
