Caffeine may help older women protect their thinking skills, according to a study in Tuesday's issue of Neurology.
The study found that women age 65 and older who drank more than three cups of coffee or tea per day had less decline over time on memory tests than women who drank a cup or less of coffee or tea daily.
Karen Ritchie, a scientist with the French National Institute for Health and Medical Research, said that a better understanding of how caffeine affects the brain is needed "before we can start promoting caffeine intake as a way to reduce cognitive decline."

Karen Ritchie, a scientist with the French National Institute for Health and Medical Research, said that a better understanding of how caffeine affects the brain is needed "before we can start promoting caffeine intake as a way to reduce cognitive decline."
The four-year study involved 7,000 people. Compared with women who drank one cup or less of coffee a day, those who drank more than three cups were less likely to show as much decline in memory.
Ritchie said that researchers don't know why caffeine didn't show the same result in men.
DVDs to educate babies
may delay infant chatter Despite marketing claims, parents who want to give their infants a boost in learning language probably should limit the amount of time they expose their children to DVDs and videos such as "Baby Einstein" and "Brainy Baby."
Rather than helping babies, the overuse of such productions may slow down infants 8 months to 16 months of age when it comes to acquiring vocabulary, say researchers at the University of Washington and Seattle Children's Hospital Research Institute.
The scientists found that for every hour a day spent watching baby DVDs and videos, infants understood an average of six to eight fewer words than infants who did not watch them. Baby DVDs and videos had no positive or negative effect on the vocabularies of toddlers 17 to 24 months of age.
The study is in today's issue of the Journal of Pediatrics. The four-year study involved 7,000 people. Compared with women who drank one cup or less of coffee a day, those who drank more than three cups were less likely to show as much decline in memory.
