Although we did not screen subjects for axis II symptomatology, all 14 members of the alcoholic cohort endorsed having been arrested in the past, compared to only four controls. The significant difference in this measure between groups, suggests that the alcoholic group was more likely to engage in excessive risk taking behavior, which is common among individuals with conduct and antisocial personality disorder. Thus, we cannot rule out the possibility that the enhanced ERN/CRN amplitudes observed in the alcoholics may have been due to a pre-morbid condition that improved with alcohol rehabilitation treatment.
