Aggressive-sadistic personality disorder (SPD) involves derivation of pleasure from another's physical or emotional suffering, or from control and domination of others. Findings from a head-injured sample indicate that SPD traits are associated with neuropsychological deficits in executive function and language, suggesting difficulties in frontal-lobe-mediated self-regulation of aggressive and emotional impulses. Implications for rehabilitation of aggressive offenders are discussed.
