London, July 15: Women have been often criticised for their inability to read maps by exasperated male drivers.

Now, scientists say binge drinking in adolescence could be the cause of the supposed phenomenon.

A group of American researchers have found that heavy drinking during teenage years, when the brain is still growing, can affect the development of spatial memory – the ability to orientate oneself on a map and remember how to get from place to place – in both sexes.

Studies among almost 100 students at schools in San Diego, California, found that the heavy drinkers performed less well on measures of spatial memory performance, with women feeling the effects more than men.

“Our study found that female teenage heavy drinkers had less brain activation in several brain regions than female non-drinking teens when doing the same spatial task,” the Independent quoted lead researcher, Susan Tapert, as saying.

“These differences in brain activity were linked to worse performance on other measures of attention and working memory ability.

“Male binge drinkers showed some but less abnormality as compared to male non-drinkers.

“This suggests that female teens may be particularly vulnerable to the negative effects of heavy alcohol use,” explained Tapert, acting chief of psychology at the Veterans Administration San Diego Health System.

The students were normal healthy teenagers who drank socially and might have four or five drinks at a weekend party and then not drink again for some weeks.

The study was published in the journal Alcoholism. (ANI)
