Disruptive Mood Dysregulation Disorder (DMDD) occurs in children or adolescents who experience ongoing irritability, anger, and frequent, intense temper outbursts.

 

The symptoms of DMDD go beyond a "bad mood." DMDD symptoms are severe. Youth with DMDD experience significant problems at home, at school, and often with peers.

 

They also tend to have high rates of health care service use, hospitalization, and school suspension, and they are more likely to develop other mood disorders.
