Vitamin D and dementia

An article in this month's Journal of Alzheimer's Disease looks into the links between vitamin D deficiency and dementia. The article, by William B. Grant, points out that low levels of vitamin D are associated with an increased risk of cardiovascular disease, diabetes, depression, dental caries, osteoporosis and periodontal disease all of which are known to either precede dementia or to be a risk factor for it. There is also evidence that vitamin D helps with neuroprotection and reducing inflammation and strong evidence that it has an important role in brain function. As many older people are deficient in vitamin D and it has many other health benefits Dr. Grant recommends that people over 60 should consider having their vitamin D levels tested.
