Disruptive Mood Dysregulation Disorder (DMDD): Causes, Risk Factors, and Treatments

Disruptive mood dysregulation disorder (DMDD) is a mental condition that can affect children and adolescents and is characterized by excessive displays of irritability or anger or by temper outbursts. Although most children experience occasional frustration and anger, those with DMDD display excessive and situationally disproportionate tantrums. They may yell, hit people, or lash out in other ways. This type of excessive temper display may negatively affect people’s lives at home, at school, and in other social circumstances.
