Disruptive Mood Dysregulation Disorder (DMDD)
A childhood disorder characterized by severe, recurrent temper outbursts that are grossly out of proportion in intensity or duration to the situation, along with persistent irritable or angry mood between outbursts. Distinguishes chronic irritability from bipolar disorder in children.
