vit-dA new study published in the Journal of Neurology concludes that low levels of Vitamin D are associated with Alzheimer’s disease and also that many older adults have severely low levels of the vitamin, putting them at a much greater risk for dementia.

The vitamin D levels in their  blood were tested, and they were followed up for an average of 5.6 years. During this follow-up period, 171 of the participants developed dementia and 102 participants developed Alzheimer’s disease.


The researchers found the participants with low levels of vitamin D were 53 percent more likely to develop dementia, and those who were severely deficient were 125 percent more likely, when compared with participants with regular levels of vitamin D.
