Caffeine may help older women ward off mental decline, research suggests.
French researchers compared women aged 65 and older who drank more than three cups of coffee per day with those who drank one cup or less per day.
Those who drank more caffeine showed less decline in memory tests over a four year period.
The study, published in the journal Neurology, raises the possibility that caffeine may even protect against the development of dementia.
The results held up even after factors such as education, high blood pressure and disease were taken into account.
