Lack of Vitamin D Linked to Alzheimer's and Vascular Dementia

"(NaturalNews) Researchers have found that low serum levels of vitamin D are associated with an increased risk for host of health problems ranging from diabetes and osteoporosis to depression, dental cavities and periodontal disease. What's more, in 2008, numerous studies concluded that people with higher serum levels of vitamin D had a greatly reduced risk of cardiovascular disease as well as a lowered chance of death due to cardiac causes. Curiously, all of these seemingly separate conditions are either known risk factors for dementia or tend to strike before dementia is diagnosed. Now scientist William B. Grant, PhD, of the Sunlight, Nutrition, and Health Research Center (SUNARC) has put these facts together and has come up with a startling new hypothesis about the cause of mind-robbing Alzheimer's disease and other vascular dementias: vitamin D deficiency."
