What disorder is diagnosed in children up to age 12 with chronic severe irritability?

The disorder characterized by chronic severe irritability in children up to age 12 is Disruptive Mood Dysregulation Disorder (DMDD). This condition reflects a pattern of severe temper outbursts that are out of proportion to the situation and are inconsistent with developmental levels. These outbursts can manifest as verbal rages or physical aggression towards people or property, occurring three or more times a week over a period of time.

DMDD was introduced as a diagnosis to address the overdiagnosis of bipolar disorder in children and to provide a clearer understanding of persistent irritability. It emphasizes the ongoing nature of mood dysregulation rather than episodic mood swings, distinguishing it from disorders like bipolar disorder, which involves distinct episodes of mania and depression.

Given this classification, DMDD is particularly relevant for children who exhibit chronic irritability and temper outbursts. The recognition of this disorder helps clinicians provide appropriate interventions tailored to managing severe mood dysregulation in the pediatric population.
