Low levels of vitamin D may increase Alzheimer’s disease risk
A new study confirms a correlation between vitamin D levels and risk of Alzheimer’s disease and dementia but does not say what causes which. For example, having dementia may cause vitamin D levels to go down, or there may be a third factor that affects both vitamin D levels and dementia risk. Clinical trials are necessary to investigate whether increasing vitamin D can delay or prevent Alzheimer’s. The Alzheimer’s Association is pleased to have provided some of the funding for this research.
