The results of a new animal study have revealed that vitamin D could play a role in reducing the level of plaques in the brain, thereby bettering cognition levels among patients with Alzheimer’s disease.
The studies were conducted on mice and found that activated vitamin D supplementation resulted in a decrease in the quantity of amyloid-beta plaques within the brain and that it enhanced cognition.
Research has already shown that vitamin D deficiency increases the risk of Alzheimer’s disease, and that supplementation of vitamin D can help to slow the progress of the condition. That said, this research helps to explain why the nutrient may have a positive impact on patients with the condition, while revealing that cognition can improve from treatments such as supplementation.
This recent study, which was conducted by Canadian researchers, determined that amyloid plaques did not accumulate as greatly in the brains of mice predisposed to the buildup of amyloid plaques when vitamin D was supplemented, when compared to a placebo group that did not receive the supplementation.
While this research is still too early to be considered proof that the same will occur among human Alzheimer’s disease patients, it does provide insight that could support further human clinical trials for potential treatment purposes.
