Overview
Intermittent explosive disorder (IED) is a mental health condition marked by frequent impulsive anger outbursts or aggression. The episodes are out of proportion to the situation that triggered them and cause significant distress.
People with intermittent explosive disorder have a low tolerance for frustration and adversity. Outside of the anger outbursts, they have normal, appropriate behavior. The episodes could be temper tantrums, verbal arguments or physical fights or aggression.
Intermittent explosive disorder is one of several impulse control disorders.
Approximately 80% of people with IED have another mental health condition, with anxiety disorders, externalizing disorder, intellectual disabilities, autism and bipolar disorder being the most common.
