B vitamins could delay dementia

 "Despite spending billions of dollars on research and development, drug companies have been unable to come up with effective treatments for dementia and Alzheimer's Disease (AD). Now, A. David Smith at the University of Oxford and his colleagues have discovered that, in some patients experiencing mild cognitive impairment (MCI), a cocktail of high-dose B vitamins could prevent gray matter loss associated with progression to AD. The study appears in the Proceedings of the National Academy of Sciences."
