BINGE drinking can have a long-lasting negative effect on the brains of teenaged girls, hitting them harder than it does young boys, a study shows.

The study by researchers from the University of California, San Diego and Stanford University found that girls who binge drink – defined as having four or more drinks for women and five or more for men – showed less activity in several brain regions than teetotal teenagers, both girl and boy.

”These differences in brain activity were linked to worse performance on other measures of attention and working memory ability,” a Stanford University psychiatry professor and co-author of the study, Susan Tapert, said.

”This suggests that female teens may be particularly vulnerable to the negative effects of heavy alcohol use,” Professor Tapert said.

Alcohol could affect teen girls’ brains more than it does their male counterparts for several reasons, including that girls’ brains develop one to two years earlier than males’, she said.
