To the contrary, the more a person drank, the more their brain volume diminished. This relationship was somewhat more pronounced in women, although women tended to be lighter drinkers.
The gender difference could be explained by biological factors, namely that alcohol is absorbed faster in women and they tend to feel the effects of alcohol more than men, the researchers said.
