A 2014 study concluded that Vitamin D deficiency is associated with smaller overall brain volumes.
Recent research used data from 427,690 participants, age 40-69, in the UK Biobank to examine Vitamin D’s association with dementia and stroke. Brain imaging data for 33,523 participants was included in this study.
Researchers found a causal association between Vitamin D deficiency and risk of dementia at the 10-year follow up with participants. Those participants with the lowest Vitamin D levels had the greatest dementia risk.
Takeaway: Identifying and treating Vitamin D deficiency is important to brain health and lowering the risk of dementia.
