Learn About Disruptive Mood Dysregulation Disorder (DMDD)

Disruptive mood dysregulation disorder (DMDD) is a childhood condition of extreme irritability, anger, and frequent, intense temper outbursts. A child with DMDD experiences irritable or angry mood most of the day, nearly every day, severe temper outbursts (verbal or behavioral) out of proportion with the child’s developmental level and situation. Most children will have trouble functioning due to irritability in more than one place (e.g., home, school, with peers). DMDD can impair a child’s quality of life and school performance and disrupt relationships with his or her family and peers. Children with DMDD may find it hard to participate in activities or make friends. Having DMDD also increases the risk of developing depression or anxiety disorders in adulthood.
