Disruptive Mood Dysregulation Disorder (DMDD) is a childhood mental health condition marked by frequent, severe temper outbursts and a persistently irritable or angry mood between outbursts. It usually affects children and adolescents and can cause problems at home, at school, and with peers.

Common signs

Children with DMDD often have temper outbursts at least three times a week, and the angry or irritable mood is present most days for a year or more. The reactions are usually bigger than expected for the situation and can happen in more than one setting, such as home and school.

How it differs

DMDD is not the same as ordinary moodiness. Unlike bipolar disorder, it does not involve clear episodes of mania or hypomania; instead, the main feature is chronic irritability with repeated outbursts.

Treatment options

Treatment often starts with psychotherapy, such as cognitive behavioral therapy or parent-focused approaches, and may also include school support and family guidance. Medication may be considered in some cases, especially when there is co-occurring ADHD or severe irritability, but it is usually monitored carefully in children.

When to seek help

A child should be evaluated if angry outbursts are frequent, intense, last for months, or interfere with daily life. It is especially important to seek help if the behavior is causing major family conflict, school problems, or concern about safety.
