Abstract

Impulsive aggression (IA) in adults is associated with brain serotonin (5-HT) system abnormalities and is more common following childhood adversity. Within aggressive behavior, IA and callous unemotional (CU) traits are core components of differentiable factors with opposing 5-HT abnormalities. We aimed to investigate 5-HT abnormalities in IA and potential correlations with severity of childhood adversity while controlling for confounding 5-HT effects of high CU traits and mental disorders.
