Low vitamin D level may increase dementia risk, New Study

Older adults with too little vitamin D in their blood may have twice the risk of developing Alzheimer’s disease as seniors with sufficient levels of the “sunshine vitamin,” a new study finds.

“We expected to find an association between low Vitamin D levels and the risk of dementia and Alzheimer’s disease, but the results were surprising – we actually found that the association was twice as strong as we anticipated,” said David Llewellyn from University of Exeter Medical School in Britain.

For the study, 1,658 people over the age of 65 who were dementia-free had their vitamin D blood levels tested.

After an average of six years, 171 participants developed dementia and 102 had Alzheimer’s disease.

The study found that people with low levels of vitamin D had a 53 percent increased risk of developing dementia and those who were severely deficient had a 125 percent increased risk compared to participants with normal levels of vitamin D.

People with lower levels of vitamin D were nearly 70 percent more likely to develop Alzheimer’s disease and those who had severe deficiency were over 120 percent more likely to develop the disease.
