“There is growing evidence for how your body relies on vitamin D to ward off inflammation, cancer, and heart disease. Having enough of it in your blood is linked to a lower risk of dying prematurely. But what about vitamin D and the brain? What is its role in cognition, or dementia, if any? As one researcher told Medical News Today this week, “we did not know if vitamin D was even present in the human brain.”

The researcher, Kyla Shea, PhD, is lead author of a study offering the first evidence that vitamin D is not only present in the brain, a healthy level of it is associated with better cognitive function and a lower risk of dementia in older adults.

The evidence comes from the postmortem study of the brains of 290 individuals who had agreed to donate their organs after death. Researchers found that higher concentrations of vitamin D across the brain were associated with up to a 33% lower chance of developing dementia.

It is early days, so precisely how vitamin D supports healthy cognitive function is not yet understood. Dr. Shea sees signs that it is involved in cell-signaling pathways that may be part of neurodegeneration, but more research is needed to build on this groundbreaking study.” Stay tuned???
