Intermittent Explosive Disorder Signs & Symptoms

Intermittent explosive disorder (IED) can be hard to spot. Learn about the warning signs & symptoms to watch for.

Understanding IED

Learn about IED

Intermittent explosive disorder, also known as IED, is a type of impulse control disorder that is predominantly characterized by chronic, unwarranted, and unprovoked acts of physical and/or verbal aggression. In order for an individual to receive a clinical diagnosis of IED, he or she must display such aggression at a minimum of twice weekly for a period of at least three months. Additionally, these aggressive acts must not have been premeditated, must result in physical and/or emotional damage, and must impair the person’s ability to function appropriately on a daily basis.

When people are suffering from IED, they act out in aggressive impulses as the result of intense feelings of tension that build up within them, of which they are incapable of handling in a healthy way. These individuals report that the only way to rid themselves of that tension is to act out in an aggressive manner, yet those acts are typically followed by feelings of remorse and embarrassment. Fortunately, there are treatment options available for those struggling with IED.

Statistics

IED Statistics

The American Psychiatric Association has reported that, in the United States, there exists a one-year prevalence of approximately 2.7% in regards to individuals who are suffering from intermittent explosive disorder. Studies have also shown that, for adolescents specifically, nearly one in 12 are said to struggle with the symptoms of IED. That being said, research has concluded that IED is much more prominent in younger individuals than it is in older individuals. Furthermore, an astounding 82% of people who suffer from intermittent explosive disorder also struggle with symptoms that are synonymous with other mental health conditions as well.

Causes and Risk Factors

Causes and risk factors for IED

The development of intermittent explosive disorder lies in a combination of genetic and environmental factors. Such factors are described briefly in the following:

Genetic: Like other mental health conditions, the onset of intermittent explosive disorder has a strong genetic link. While there has yet to be any specific gene identified as directly correlating to the presence of this mental illness, studies have shown that people who have families who suffer from impulse control disorders, such as IED, are more susceptible to developing the condition themselves. This is said to be especially true for individuals who have first-degree, biological relatives who have struggled with symptoms of IED.

Environmental: Many experts in the field have concluded that the onset of IED can lie in the exposure to certain environmental factors. For example, individuals who have grown up in tumultuous environments where they were exposed to things such as violence, abuse, crime, and/or substance abuse are at a higher risk of displaying the symptoms of IED than are individuals who did not grow up in similar environments.

Risk Factors:

  • Being male
  • Having been exposed to violence at an early age
  • Presence of a preexisting mental health condition
  • Family history of impulse control disorders or other mental health conditions
  • Personal or family history of substance abuse
  • Suffering from certain medical conditions
