Intermittent Explosive Disorder

February 7, 2025

Intermittent Explosive Disorder (IED) is a mental health condition characterized by recurrent episodes of impulsive, aggressive, or violent behavior and angry verbal outbursts that are disproportionate to the situation. These episodes are typically brief, lasting less than 30 minutes, and can include physical aggression towards people, animals, or property, as well as verbal aggression such as shouting or heated arguments. Individuals with IED often experience a sense of relief following an outburst, but this is usually followed by feelings of remorse or embarrassment. The disorder can lead to significant impairment in social, occupational, or academic functioning and can cause distress for both the individual and those around them. The individual’s mood in between episodes is generally positive; the individual does not show pervasive anger or irritability or low mood apart from the episodic outbursts.

The diagnosis of IED is based on the criteria outlined in the DSM-5, which requires a pattern of aggressive outbursts that are not premeditated and are not committed to achieve a tangible objective. The exact causes of IED are not fully understood, but it is believed to result from a combination of genetic, environmental, and developmental factors. A family history of mental health disorders, stress exposure, and certain brain chemistry imbalances may increase the risk of developing IED. Diagnosis typically involves a comprehensive evaluation by a mental health professional, who will assess the individual's history of aggressive behavior and rule out other potential causes.

Treatment for IED often involves a combination of psychotherapy and/or medication. Cognitive-behavioral therapy (CBT) is commonly used to help individuals recognize triggers and develop coping strategies to manage their anger. Dialectical Behavioral Therapy (DBT) can be helpful because it teaches skills in emotional regulation, distress tolerance, and interpersonal effectiveness, which are essential for managing impulsive and aggressive behaviors. Medications such as antidepressants, mood stabilizers, or anti-anxiety drugs may also be prescribed to help control symptoms. For parents seeking additional resources, the book The Explosive Child by Dr. Ross Greene is a valuable guide. This book offers a compassionate and practical approach to understanding and parenting children with explosive behaviors, emphasizing the importance of collaborative problem-solving and addressing deficits in flexibility, frustration tolerance, and problem-solving skills. By utilizing these strategies, parents can better support their children in managing their emotions and reducing the frequency and intensity of outbursts.
