Study Reveals Why People Get Aggressive when they Drink


Researchers have pinpointed why people get aggressive after they drink alcohol.

This study by researchers at the UNSW School  of Psychology found that the brain areas normally involved in tempering aggression, the prefrontal cortex shuts off when people drink, after just 2 drinks.This is contrary to previously held beliefs that alcohol related aggression is caused by changes in the pre-frontal cortex.

The findings were published in the journal Cognitive, Affective, & Behavioral Neuroscience.

While the cause of alcohol-related aggression is disputed, we can all agree that excessive alcohol consumption can lead to aggressive behaviour which we’ve seen lead to crimes such as one punch attacks.

Responsible service of alcohol is crucial in minimising incidents caused by alcohol related aggression.
