"

" What kind of alcoholic beverage is best? The study, which appears in today's Neurology, doesn't answer that question. But wine, and particularly red wine, contains natural chemicals called polyphenols that might protect the aging brain from Alzheimer's, Solfrizzi says. "

" The Italian team studied 1,445 healthy adults 65 and older and 121 who already had been diagnosed with MCI. People with the condition experience more than the usual age-related memory glitches, but they don't show other signs of dementia, such as impaired reasoning, says Solfrizzi, a geriatrician at the University of Bari in Italy.
