Which disorder is characterized by severe and frequent temper tantrums in children aged 6-10 and symptoms lasting for at least one year?

Disruptive Mood Dysregulation Disorder (DMDD) is specifically characterized by severe and recurrent temper outbursts that are excessively disproportionate to the situation and can manifest as verbal rages or physical aggression. The key criteria for DMDD include the presence of these temper tantrums occurring frequently—often three or more times per week—and lasting for at least one year. This disorder is typically diagnosed in children aged 6 to 18 years and was developed to address concerns about the over-diagnosis of pediatric bipolar disorder.

Understanding that DMDD differs from other disorders is crucial. For example, Major Depressive Disorder primarily involves persistent sadness or loss of interest, and while temper-related symptoms can occur, they are not the hallmark feature. Attention-Deficit/Hyperactivity Disorder emphasizes inattention and hyperactivity/impulsivity, rather than the severe mood dysregulation seen in DMDD. Oppositional Defiant Disorder may involve defiance and argumentative behavior, but it does not specifically require the severe and frequent temper outbursts characteristic of DMDD.

This specificity in symptoms and diagnostic criteria assists clinicians in accurately identifying and treating DMDD, thereby facilitating appropriate interventions for affected children.
