Underage binge drinking can create lasting brain changes
Date:4/4/2011

CHAPEL HILL, N.C. - Adolescents represent the majority of people who binge drink. This may come as a surprise to some, but recent surveys indicate that episodes of heavy alcohol drinking within the previous two weeks are reported by 12 percent of 8th graders, 22 percent of 10th graders, 28 percent of 12th grade seniors and 44 percent of college students.

Human adolescence, roughly between 12 to 20 years of age, marks a critical period for brain development. This is when the growth of the cortex, our gray matter, reaches a peak and is coupled with major rearrangements of neurons. Some guess that such brain remodeling during development help us adapt to life's demands as we mature toward adulthood.

"It's also a time when the brain's developing neural circuits are more sensitive to disruption," said Fulton Crews, PhD, professor of pharmacology and director of the Bowles Center for Alcohol Studies at the University of North Carolina at Chapel Hill School of Medicine. "And we and others have shown that the growing adolescent frontal cortex is much more sensitive to damage than the adult frontal cortex, given the same amount of alcohol.

"The question is, what impact does alcohol binge-drinking in the teen years have on the brain and how might that affect our lives as adults?"

For more than a decade, Crews' research has explored the mechanisms, characteristics and functional consequences of binge drinking on the brain. His latest findings in laboratory mice, reported in the April issue of the journal Alcoholism: Clinical and Experimental Research, point to the kind of subtle but persistent alterations in the brain's frontal cortex that could affect decision-making and related behaviors in human adults.

Among the changes associated with adolescent alcohol binge drinking, magnetic resonance imaging (MRI) revealed smaller forebrain volume and size in adult animals. In separate reversal learning experiments, the anima
