Brain growth inhibited by heavy alcohol use

New research in nonhuman primates shows that heavy use of alcohol can actually slow the rate of growth in developing brains. The study, to be published April 1, in the journal eNeuro, shows that heavy alcohol use reduced the rate of brain growth by 0.25 milliliters per year for every gram of alcohol consumed per kilogram of body weight. In human terms, that's the equivalent of four beers per day.
