Intermittent explosive disorder often co-occurs with other psychiatric disorders. For example, of 46 impulsive violent offenders ( n = 24) and fire-setters (n = 22) in one study,(8) 33 (72 per cent) of whom met the DSM-III criteria for intermittent explosive disorder, 44 (96 per cent) had a lifetime diagnosis of alcohol abuse, 41 (89 per cent) had borderline personality disorder, 24 (52 per cent) had a mood disorder, and nine (20 per cent) had antisocial personality disorder. Of 27 subjects with DSM-IV intermittent explosive disorder evaluated with the Structured Clinical Interview for DSM-IV, (6) 25 (93 per cent) met lifetime criteria for a mood disorder (with 15 (55 per cent) meeting criteria for a bipolar disorder), 13 (48 per cent) for a substance use disorder, 13 (48 per cent) for an anxiety disorder (with six (22 per cent) meeting criteria for obsessive-compulsive disorder), six (22 per cent) for an eating disorder, and 12 (44 per cent) for an impulse control disorder other than intermittent explosive disorder.(6)
