DMDD: What Is It?
Disruptive mood dysregulation disorder (DMDD) is a condition in which a child is chronically irritable and experiences frequent, severe temper outbursts that seem grossly out of proportion to the situation at hand. DMDD is a new disorder created to more accurately categorize some children who had previously been diagnosed with pediatric bipolar disorder. These children do not experience the episodic mania or hypomania characteristic of bipolar disorder, and they do not typically develop adult bipolar disorder, although they are at elevated risk for depression and anxiety as adults. Unlike pediatric bipolar disorder, DMDD is thought to occur more often in boys than girls.
