Aggressive children are often alienated from parents, separated from peers, placed in special education and segregated with other aggressive children. While predatory (i.e. planned, goal directed, reward driven) aggression is not responsive to pharmacologic treatment, non predatory (impulsive, paranoid, irritable) aggression (DSM-IV-TR "Intermittent Explosive Disorder") often is. Intermittent Explosive Disorder is characterized by discrete episodes of failure to resist aggressive impulses resulting in serious assaults or destruction of property. In children, due to their limited ability to damage or hurt others, the seriousness of the aggressive impulses are indicated by (a) the frequency and severity of tantrums (b) the fact that the severity is out of proportion to the provocation, and (c) the intent to damage and hurt is present and (d) this pattern of events causes impairment.
