Intermittent explosive disorder (IED) is an often overlooked mental disorder identified by episodes of anger, sudden outbursts in which the person loses control entirely.

This mental disorder usually begins in childhood or adolescence. Most people continue to experience it later in their life, though. 

The treatment for intermittent explosive disorder may vary from person to person, but the general treatment methods are psychotherapy and medication.

Intermittent explosive disorder makes you aggressive and violent without any specific reason. It involves a series of verbal outbursts, physical fights, and sudden anger.

Some signs can help you identify your condition. People with this disorder usually throw or break things, abuse others, and display road rage.

This behavior stresses you out and affects your everyday activities and relationships. In most cases, it can also lead you to financial and legal loss.

Intermittent explosive disorder affects around 11.5 to 16 million Americans in their lifetimes, including 7.3% of adults. 

It is a chronic disorder that usually decreases with age.

Several environmental and genetic factors can contribute to this disorder's development. Some known intermittent explosive disorder causes include:

  • Family history (heredity)
  • Experiencing any sort of abuse, verbal or physical, in childhood
  • Brain function and chemistry, especially varying levels of serotonin
  • Long-lasting trauma
  • Mental health disorders, such as ADHD, antisocial personality disorder, and borderline personality disorder
  • Depression, anxiety-related symptoms, or substance-abuse disorder

An intermittent explosive disorder episode can happen at any time. Some people have episodes daily, while others stay nonaggressive for weeks and months. A typical incident lasts for less than 30 minutes. 

People with IED experience varying intensity of symptoms. Some may feel less of an urge to be verbally abusive but may show severe physical aggression. 

Common intermittent explosive disorder symptoms are:

  • Sudden rage
  • Frustration 
  • Irritability with human contact
  • Scattered thoughts
  • High energy levels
  • Tightness in the chest
  • Tingling: an unusual sensation in your hands, legs, and arms
  • Tremors: a rhythmic shaking movement in your hands, arms, legs, or trunk
  • Palpitations: racing heartbeat

Some other intermittent explosive disorder symptoms can be:

  • Anger tantrums
  • Unnecessary tirades or invectives, use of abusive words to convey a message
  • Starting heated arguments
  • Aggressive shouting
  • Use of hands on another person, such as slapping or pushing
  • Damage to personal or private property
  • Threatening people or animals to let out the anger

People with intermittent explosive disorder do such things out of impulsiveness. Most of them regret their behavior later.

Doctors usually consult the standard Psychiatric Diagnostic Manual to diagnose the disorder better. It says that an individual must experience three episodes of IED at any stage of their life to be diagnosed. 

These episodes should not be caused by any sort of external or internal factor. The person must also show physical symptoms, like hurting someone or damaging property.

If you have experienced such episodes, visit your doctor for a professional diagnosis.

The best intermittent explosive disorder treatment is psychotherapy. Some doctors may also suggest medications along with the therapy.


Cognitive behavioral therapy helps people with IED to control and change their behaviors. It can help you:

  • Identify the triggers of your aggressive reactions
  • Manage and control your violent behavior with relaxation techniques and thinking practices. 
  • Work on your communicative and problem-solving skills.

Medical Treatment

Antidepressants like serotonin reuptake inhibitors (SSRIs) and anticonvulsants may help you stabilize your mood. Your doctor may also prescribe other drugs.

People with IED usually don't have control over themselves. You can control your anger, though, with professional treatment and by following some tips:

  • Think differently. You can't make a difference without reconstructing your thoughts, so try to find logical reasons in an aggressive situation and react to it rationally.
  • Follow your treatment plan. Never miss your therapy sessions and any medication prescribed by the doctor. If you think you don't need it, still talk to your doctor before deciding anything on your own.
  • Work on your communication skills. Try to listen to the other person's reason before reacting to it impulsively. 
  • Practice relaxation techniques. Include breathing exercises in your routine and meditate regularly.
  • Make a change in your routine. Following a specific pattern often increases frustration in a person, so make a schedule of your day and add different activities to it. 
  • Avoid mood-altering substances. Alcohol and recreational drugs have a significant impact on your mood. Try to avoid them as a whole.
