The authors of a recent study published in Neurology aimed to “test the hypothesis that low levels of Vitamin D is associated with a higher risk of cognitive decline over a 4.4-year follow-up in a large sample of older adults.” The authors conducted an Italian population-based cohort study of 1,927 older adults, and assessed their vitamin D levels and global cognitive function at baseline. The study found that participants with Vitamin D deficiency or insufficiency were more likely to have declining cognitive function during the follow up than those who had sufficient Vitamin D. The authors conclude that the study “supports an independent association between low Vitamin D levels and cognitive decline in elderly individuals.”
