Enhancing Dentate Gyrus Function with Dietary Flavanols Improves Cognition in Older Adults

Earlier this month, CBS News aired a feature on a joint, ongoing study by the Taub Institute (Drs. Scott Small and Adam Brickman) and the Division of Behavioral Medicine (Drs. Richard Sloan and Paula McKinley) on how dietary cocoa flavanols — naturally occurring bioactives found in cocoa —reversed age-related memory decline in healthy older adults. Previous results from a first study, published in Nature Neuroscience, provided the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention. These investigators are currently recruiting for another, larger study on the effects of cocoa flavanols.
