Intermittent explosive disorder (IED) is a condition that involves sudden outbursts of rage, aggression, or violence. These reactions tend to be irrational or out of proportion to the situation.
While most people lose their temper once in a while, IED involves frequent, recurring outbursts. Individuals with IED might throw tantrums, destroy property, or attack others verbally or physically.
Read on to learn some common signs of IED.
The impulsive, aggressive episodes that characterize IED can take many forms. Some behaviors that might be signs of IED include:
- yelling and shouting
- intense arguments
- temper tantrums and rampages
- road rage
- punching walls or breaking plates
- damaging property
- physical violence, such as slapping or shoving
- fights or brawls
- domestic violence
These spells or attacks often occur with little to no warning. They are short-lived, rarely lasting longer than half an hour. They may appear alongside physical symptoms, such as:
- increased energy (adrenaline rush)
- headache or head pressure
- heart palpitations
- chest tightness
- muscle tension
Feelings of irritation, rage, and loss of control are commonly reported before or during the episode. People with IED might experience racing thoughts or a sense of emotional detachment. Immediately after, they might feel tired or relieved. People with IED often report feelings of remorse or guilt following an episode.
For some individuals with IED, these episodes occur on a regular basis. For others, they occur after weeks- or months-long stretches of nonaggressive behavior. Verbal outbursts may occur between acts of physical violence.
The new edition of the Diagnostic and Statistical Manual (DSM-5) includes updated diagnostic criteria for IED. The new criteria distinguish between:
- more frequent episodes of verbal aggression without physically harming people or property
- less frequent acts of destructive or assaultive behavior that causes serious harm to people or property
A disorder characterized by impulsive and aggressive behavior has appeared in all editions of the DSM. However, it was first called IED in the third edition. Prior to the third edition, it was believed to be rare. With updated diagnostic criteria and advances in IED research, it’s now believed to be much more common.
In 2005, a
Little is known about what causes IED. The cause is likely a combination of genetic and environmental factors. Genetic factors include genes passed from parent to child. Environmental factors include behaviors that a person is exposed to as a child.
You might be at an increased risk of developing IED if you:
- are male
- are under the age of 40
- grew up in a verbally or physically abusive household
- experienced multiple traumatic events as a child
- have another mental illness that causes impulsive or problematic behavior, such as:
There are a number of treatments for IED. Most of the time, more than one treatment is used.
Seeing a counsellor, psychologist, or therapist alone or in a group setting may help a person manage symptoms of IED.
Cognitive behavioral therapy (CBT) is a type of therapy that involves identifying harmful patterns and using coping skills, relaxation techniques, and relapse education to deal with aggressive impulses.
A 2008 study found that 12 weeks of individual or group CBT reduced IED symptoms including aggression, anger control, and hostility. This was true both during treatment and after three months.
There are no specific medications for IED, but certain medications may help to reduce impulsive behavior or aggression. These include:
- antidepressants, in particular selective serotonin reuptake inhibitors (SSRIs)
- mood stabilizers, including lithium, valproic acid, and carbamazepine
- antipsychotic drugs
- antianxiety drugs
It can take up to three months of treatment to experience the full effects of SSRIs, and symptoms tend to reappear once medication is stopped. In addition, not everyone responds to medication.
Few studies have explored the effectiveness of alternative treatments and lifestyle changes for IED. Still, there are a number of interventions that aren’t likely to have a negative impact. Some of these include:
- adopting a balanced diet
- getting enough sleep
- staying physically active
- avoiding alcohol, drugs, and cigarettes
- reducing and managing sources of stress
- making time for relaxing activities, such as listening to music
- practicing meditation or other mindfulness techniques
- trying alternative therapies, such as acupressure, acupuncture, or massage
IED can impact your close relationships and everyday activities. Frequent arguments and more aggressive behavior can make it difficult to maintain stable and supportive relationships. Episodes of IED can cause significant harm within families.
You might also experience consequences after behaving aggressively at work, school, or on the road. Loss of a job, expulsion from school, car accidents, and financial and legal repercussions are all possible complications.
People who have IED are at an increased risk of having other mental and physical health issues. Some of these include:
- alcohol or substance misuse
- other risky or impulsive behaviors, such as problem gambling or unsafe sex
- eating disorders
- chronic headaches
- high blood pressure
- heart disease
- chronic pain
- self-harm and suicide
- If you think someone is at immediate risk of self-harm or hurting another person:
- • Call 911 or your local emergency number.
- • Stay with the person until help arrives.
- • Remove any guns, knives, medications, or other things that may cause harm.
- • Listen, but don’t judge, argue, threaten, or yell.
- If you or someone you know is considering suicide, get help from a crisis or suicide prevention hotline. Try the National Suicide Prevention Lifeline at 800-273-8255.
Many people who have IED don’t seek treatment. But it’s nearly impossible to prevent episodes of IED without professional help.
If you suspect that you have IED, make an appointment with a doctor or other mental health professional. If you feel you might harm yourself or someone else, call 911 immediately.
If you’re in a relationship with someone whom you suspect has IED, you can ask your loved one to seek help. However, there are no guarantees that they will. IED shouldn’t be used as an excuse for aggressive or violent behavior toward you.
