Adolescent Binge Drinking Causes Long-Lasting Brain Changes, Study Finds.

Heavy drinking during adolescence can lead to thinner cortical gray matter and altered neurotransmission in adulthood, according to a recent study. The research, which utilized MRI and TMS-EEG technology, found that young adults with a history of heavy drinking exhibited lower gray matter thickness and increased N45 potential, indicative of inhibitory GABA and excitatory glutamate neurotransmitter activity. The study highlights the long-term, detrimental impact of adolescent heavy drinking on adult brain structure and function, particularly in the frontal and parietal lobes.
