Vitamin D Deficiency Linked to Dementia Risk

iStockphoto/Thinkstock(NEW YORK) -- Researchers have found a possible link between Vitamin D deficiency and increased risk of dementia.

In a study published in the journal Neurology, researchers said they looked at over 5,000 patients and found that those with vitamin D levels that qualified as "severely deficient" were 122 percent more likely to develop dementia than those who received sufficient levels of the nutrient. Those patients who were merely "deficient" were 51 percent more likely to develop dementia.

Researchers tested the results excluding certain factors -- including alcohol use, education level, age, sex and smoking status -- and found that their findings remained accurate.
