Dementia Risk and Vitamin D

This podcast episode from the Psychopharmacology Institute discusses a UK Biobank study investigating the link between vitamin D levels and dementia risk. Dr. Richard Seeber interviews Dr. Scott Beach, who explains the study's findings: vitamin D deficiency was associated with a 25% increased dementia risk, and insufficiency with an 11% increase. The study also showed a correlation between vitamin D supplementation and a lower Alzheimer's risk, particularly in younger individuals. While acknowledging the observational nature of the study and the lack of causal conclusions, Dr. Beach highlights the prevalence of vitamin D deficiency and suggests that checking vitamin D levels, especially in middle-aged and older patients, and recommending supplementation where necessary, could be a valuable preventative measure. The discussion emphasizes the importance of this simple, affordable intervention as part of a broader approach to brain health.
