All of the following are symptoms of disruptive mood disorder except.

A. Severe temper outbursts. Disruptive Mood Dysregulation Disorder (DMDD) is characterized by frequent, severe temper outbursts that are out of proportion to the situation. These outbursts can be verbal or physical and occur at least three times per week, persisting for one year or more. B. Struggle to regulate emotions. Individuals with DMDD have difficulty managing emotions, particularly anger and frustration. This emotional dysregulation leads to persistent mood instability, which interferes with daily functioning at home, school, and in social settings. C. Hyperactivity. Hyperactivity is not a core symptom of DMDD but is more commonly associated with Attention-Deficit/Hyperactivity Disorder (ADHD). While some children with DMDD may also have ADHD, DMDD primarily involves severe mood disturbances rather than impulsivity or excessive movement. D. Chronic irritability. Persistent irritability is a hallmark of DMDD, with children and adolescents experiencing near-constant irritability between temper outbursts. Unlike episodic mood disorders like bipolar disorder, DMDD symptoms are chronic and ongoing without distinct mood episodes.
