Disruptive Mood Dysregulation Disorder (DMDD) is a relatively new mental health diagnosis primarily affecting children and adolescents. It is characterized by severe and recurrent temper outbursts that are disproportionate to the situation and inconsistent with the individual’s developmental level. These outbursts can include verbal and physical aggression and can occur three or more times per week.

Children with DMDD often experience persistent irritability and anger between temper outbursts. They may have trouble regulating their emotions, exhibit a negative mood, and have difficulty getting along with peers and authority figures. The disorder typically emerges before the age of 10 and can persist into adolescence and adulthood, although symptoms may change over time.
