There are several risk factors for the development of Alzheimer's disease and vascular dementia. An increasing number of studies link these risk factors with vitamin D deficiency. Dr. William B. Grant of the Sunlight, Nutrition, and Health Research Center (SUNARC) suggests that further investigation of possible direct or indirect linkages between vitamin D and these dementias are needed.
Low serum levels of 25-hydroxyvitamin D have been associated with increased risk for cardiovascular diseases, diabetes mellitus, depression, dental caries, osteoporosis, and periodontal disease, all of which are either considered risk factors for dementia or have preceded incidence of dementia.
