Midlife vitamin D deficiency linked to Alzheimer's risk, study finds
A study analyzing Framingham Heart Study data links midlife vitamin D deficiency to increased Alzheimer's risk, especially in memory-related brain regions.
Key Takeaways
AIA study has found that vitamin D deficiency in midlife is associated with the development of Alzheimer's disease, based on an analysis of data from 793 participants in the Framingham Heart Study.
Researchers measured the accumulation of both tau and beta-amyloid proteins—two substances linked to Alzheimer's progression—in the volunteers. The results, reported by Russia Today, showed that higher vitamin D levels in midlife were linked to lower amounts of tau protein in the brain.
According to the study, this association was most pronounced in brain regions typically affected in the early stages of Alzheimer's, such as the temporal lobe and areas responsible for memory. However, the study found no link between vitamin D levels and beta-amyloid accumulation.
