Low vitamin D levels may be linked to dementia

Experts say someone in the U.S. develops Alzheimer's disease every 67 seconds. And now, a recent study suggests the disease and other forms of dementia might be linked to a vitamin D deficiency.

The study, published in the journal Neurology, followed more than 1,600 seniors over six years, after which more than 170 developed dementia and more than 100 developed Alzheimer's.

And the researchers say the risk of developing dementia increased by more than 50 percent in those with low levels of vitamin D. The risk in those with a severe vitamin D deficiency increased by 125 percent.

Now, that might lead you to assume vitamin D deficiency causes dementia. But the authors warn that might not be the case, and the answer might not be as simple as taking vitamin D supplements.
