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 out of proportion to the situation at hand. Children diagnosed with DMDD struggle to regulate their emotions in an age-appropriate way. In between outbursts they are irritable most of the time.
DMDD is a new disorder created to more accurately diagnose children who were previously diagnosed with pediatric bipolar disorder, even though they did not experience the episodic mania or hypomania characteristic of bipolar disorder.
