What intermittent explosive disorder actually is
Intermittent explosive disorder, often shortened to IED, is a DSM-5-TR diagnosis defined by repeated outbursts of aggression that a person can’t hold back. The reaction is grossly out of proportion to whatever triggered it, and it isn’t planned. The aggression is impulsive and anger-driven rather than aimed at getting something tangible.
The DSM-5-TR describes two patterns that can meet criteria. One is frequent, lower-intensity outbursts, such as verbal arguments or aggression that doesn’t damage property or hurt anyone, happening roughly twice a week for at least three months. The other is more serious outbursts that involve damage, injury, or physical assault, occurring three times within a year. Either pattern can support the diagnosis.
The outbursts have to cause real distress, problems at work or home, or legal and financial fallout. The diagnosis is generally made in people at least 6 years old, and the aggression can’t be better explained by another condition, a medication, or a substance.
What intermittent explosive disorder can feel like
People often describe the outbursts as coming on fast, with little warning. Tension or irritability builds, and then there’s a sudden release of anger that feels almost automatic. Some notice physical signs first, like a racing heart or a flush of heat.
Afterward, many feel remorse, embarrassment, or confusion about what just happened. The gap between how small the trigger was and how big the reaction was can be distressing on its own. Over time, the outbursts strain relationships, jobs, and a person’s sense of control.
What intermittent explosive disorder isn’t
IED isn’t ordinary anger or a short temper. Everyone gets angry, and occasional blowups don’t meet the diagnostic threshold. The disorder is about a recurring pattern of impulsive aggression that’s clearly disproportionate and causes real harm or distress.
It also isn’t the same as planned or goal-directed aggression. The outbursts in IED are impulsive, not calculated, which is one way it’s separated from conditions like antisocial personality disorder. And it’s different from a single, isolated incident, since the diagnosis depends on a repeated pattern.

Irritability and emotional dysregulation describe the inner state that often precedes outbursts. Distress tolerance is a skill used in treatment, and agitation is a related state of restlessness and tension.
When to seek professional care
If anger leads to repeated outbursts that feel out of control and are damaging relationships, work, or safety, a clinical evaluation is appropriate. IED can be treated, often with therapy that builds impulse control and sometimes with medication. If aggression has put anyone’s safety at risk, reaching out for help sooner rather than later is the safer path.
When this word matters
It matters when anger turns into repeated, impulsive outbursts that are clearly out of proportion to the trigger and cause real harm or distress, not just an occasional bad temper. The recurring, disproportionate pattern is what defines the disorder.
