Vitamins and Dementia

No hard evidence supports supplements', vitamins' promise in slowing cognitive decline.
CNN (4/26, Landau) reported, "A seemingly steady stream of new research purports to show supplements' and vitamins' promise in preventing or slowing cognitive decline, but in reality no hard evidence supports taking any of them." But, "at the same time, such supplements have been proved safe, barring drug interactions and other complications, so some doctors recommend trying them anyway." The article discussed claims regarding omega 3 fatty acid fish oils, gingko biloba, and vitamin E for preserving cognition, pointing out that studies have found inconclusive or mixed benefits for each of these supplements.
