NIDA Research: Reduced Activity in One Brain Region Links Childhood Adversity to Aggression/Delinquency and Substance Use in Adolescents
Reduced Activity in One Brain Region Links Childhood Adversity to Aggression/Delinquency and Substance Use in Adolescents
This study found that:
People who experienced more childhood adversity had higher rates of substance use in late adolescence.
Children who experienced adversity were more likely to show externalizing behavior (e.g., aggression, delinquency) in early adolescence, which in turn predicted substance use in late adolescence.
Reduced activation of the brain’s anterior cingulate cortex mediates the relationship between childhood adversity and increased externalizing behavior.
