Flavanols improve memory in study of older individuals

Flavanols improve memory in study of older individualsOctober 27 2014. A study described on October 26, 2014 in Nature Neuroscience revealed improvement in an area of the brain that undergoes changes associated with age-related memory loss, among subjects given a high amount of cocoa flavanols.  Flavanols are compounds that naturally occur in cocoa beans, tea and other plants, which have been associated with several health benefits, including a lower risk of diabetes.

For the current study, 37 participants aged 50 to 69 were given a cocoa beverage that provided 900 mg or 10 mg flavonols per day for three months. Neuropsychological tests of memory function specifically localized to the brain’s dentate gyrus and dentate gyrus blood volume imaging were conducted before and after treatment.

"When we imaged our research subjects' brains, we found noticeable improvements in the function of the dentate gyrus in those who consumed the high-cocoa-flavanol drink," reported lead author Adam M. Brickman, PhD, of the Taub Institute for Research on Alzheimer's Disease and the Aging Brain at Columbia University.
