Meth messes up brains of youths far more than those of adults

Adolescents who chronically use methamphetamine suffer greater and more widespread alterations in their brain than adults who chronically abuse the drug-and damage is particularly evident in a part of the brain believed to control the "executive function," researchers from the University of Utah and South Korea report.

"It's particularly unfortunate that meth appears to damage that part of the brain, which is still developing in young people and is critical for cognitive ability," says In Kyoon Lyoo, M.D., Ph.D., of Ewha W. University in Seoul, South Korea. "Damage to that part of the brain is especially problematic because adolescents' ability to control risky behavior is less mature than that of adults. The findings may help explain the severe behavioral issues and relapses that are common in adolescent drug addiction."
