Coffee may slow memory declines in women: study

By Ishani Ganguli

WASHINGTON (Reuters) - Drinking more than three cups of coffee a day helped protect older women against some age-related memory decline, French researchers said on Monday, giving women more reason to love the world's most popular stimulant.

Men did not enjoy the same benefit, they said.

"The more coffee one drank, the better the effects seemed to be on (women's) memory functioning in particular," said Karen Ritchie at the French National Institute of Medical Research, whose work appears in the journal Neurology.

The researchers followed more than 7,000 men and women in three French cities, checking their health and mental function and asking them about their current and past eating and drinking habits, their friends, and their daily activities.

They used this information to sort out the specific role caffeine played in these women's lives.

They found that women who drank more than three cups of coffee per day, or its caffeine equivalent in tea, retained more of their verbal and -- to a lesser extent -- visual memories over four years.

These women had a 33 percent lower odds of having verbal memory declines and 18 percent lower odds of having visual and spatial memory declines, compared to women who drank one cup or fewer per day.

The effect also depended on age, with women over 80 reaping more benefits from these beverages than those who were 10 to 15 years younger, Ritchie's team wrote. It was unclear whether current or former coffee consumption made the difference.
