Objective To evaluate the anti-aggressive effect of Buspirone in aggressive individuals with DSM-Ⅳ antisocial personality disorder.Methods The Point-Subtraction Aggression Paradigm(PSAP) and the Modified Overt Aggression Scale (MOAS) were used to assess the anti-aggression effects of Buspirone in a case control study,in which 20 subjects with antisocial personality disorder were included in the study group with Buspirone treatment,and another 20 personality disorder subjects in cotrol group without drug.Results The efficacy rate of study group assessed with MOAS was 100%,which was significantly higher than that of control group (25%) after four weeks of treatment.The efficacy rate assessed with PSAP-B response and PSAP-B response per point subtraction was 70% and 68.4% in study group,and 50% and 50% in control group.Conclusion Buspirone treatment has an antiaggressive effect on DSM-Ⅳ antisocial personality disorder subjects.
