Flavanol and dementia

Researchers have told the annual meeting of the American Association for the Advancement of Science that an antioxidant found in cocoa beans may help maintain brain function in older people. Ian MacDonald, of the University of Nottingham, says women given cocoa high in flavanols show a significant increase in blood flow to the brain, and that this raises the prospect of using flavanols in the treatment of dementia as well as in maintaining overall cardiovascular health.
