Symptoms.

Intermittent Explosive Disorder is marked by several discrete episodes of failure to resist aggressive impulses that result in serious assaultive acts or destruction of property.
The degree of aggressiveness expressed during the episodes is grossly out of proportion to any precipitating psychosocial stressors.
The aggressive episodes are not better accounted for by another mental disorder (such as Antisocial Personality Disorder, Borderline Personality Disorder, a Psychotic Disorder, a Manic Episode, Conduct Disorder, or Attention-Deficit/Hyperactivity Disorder) and are not due to the direct physiological effects of a substance (such as a medication or a drug of abuse) or a general medical condition (such as head trauma, Alzheimer's disease)
Individuals with Intermittent Explosive Disorder sometimes describe intense impulses to be aggressive prior to their aggressive acts. Explosive episodes may be associated with affective symptoms such as irritability or rage, increased energy, and racing thoughts during the aggressive impulses and acts, and rapid onset of depressed mood and fatigue after the acts. Some individuals may also report that their aggressive episodes are often preceded or accompanied by symptoms such as tingling, tremors, palpitations, chest tightness, head pressure, or hearing an echo. This disorder may result in job loss, school suspension, divorce, difficulties with interpersonal relationships or other impairment in social or occupational areas, accidents (such as in vehicles), hospitalization because of injuries from fights or accidents, financial problems, incarcerations or other legal problems.
