Intermittent explosive transtorno is characterised by repeated brief episodes of verbal or physical aggression or destruction of property that represent a failure to control aggressive impulses, com the intensity of the outburst or degree of aggressiveness being grossly out of proportion to the provocation or precipitating psychosocial stressors. The symptoms are not better explained by another mental, behavioural, or neurodevelopmental transtorno and are not part of a padrão of chronic anger and irritability (e.g., in oppositional defiant transtorno). The behaviour padrão is of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning.
