Binge drinking in adolescence has been shown to have lasting effects on the wiring of the brain and is associated with increased risk for psychological problems and alcohol use disorder later in life. Now, researchers at the University of Illinois at Chicago Center for Alcohol Research in Epigenetics have shown that some of these lasting changes are the result of epigenetic changes that alter the expression of a protein crucial for the formation and maintenance of neural connections in the amygdala — the part of the brain involved in emotion, fear and anxiety. Their results, which are based on the analysis of postmortem human brain tissue, are published in the journal Translational Psychiatry.
