D for Dementia - Key vitamin deficiency linked to memory decline
Beta amyloid, tau proteins, and now...Vitamin D.
A new study published in the journal Neurology uncovers a link between Alzheimer's, other forms of dementia, and Vitamin D deficiency. What remains unclear is a clear cause-and-effect. CBS Sunday Morning covers the research further (highlights below the video - VIDEO NO LONGER AVAILABLE 2021):
*Vitamin D has long been considered essential to bone health, moderating cell growth, and regulating immune function and inflammation.
*Still not clear whether increasing Vitamin D intake (through dietary changes, sun exposure, etc) would help once disease onset begins
*Researchers for this study evaluated over 1,000 subjects age 65+. All subjects were considered mentally healthy at the time of recruitment and then re-evaluated 6-7 years later at the end of the study. Blood samples were drawn at the beginning of the study as well.
