Brain imaging study suggests both cutting down and quitting drinking linked to healthier brains

The brains of people who reduce their drinking, as well as of people who quit drinking entirely, have greater volume in certain regions than people who drink more heavily, according to a new study of adults treated for alcohol use disorder. The regional brain volumes of people who resume drinking at low-risk levels (no more than approximately three drinks per day for males, 1.5 drinks per day for females) of alcohol are more similar to the brains of those who remain abstinent than they are to those who drink at higher risk levels (average of five or more drinks per day).
