Can You Have IED and ODD? Understanding the Relationship Between Intermittent Explosive Disorder and Oppositional Defiant Disorder

The co-occurrence of Intermittent Explosive Disorder (IED) and Oppositional Defiant Disorder (ODD) has been a topic of research interest within the field of child and adolescent psychiatry. Surprisingly, the odds ratios for these comparisons didn’t differ from each other or from the community sample, suggesting that individuals with IED may also have a high likelihood of exhibiting ODD symptoms. This raises important questions about the relationship between these two disorders and the potential underlying mechanisms that contribute to their co-occurrence. Understanding the interplay between IED and ODD could have significant implications for diagnostic clarity, treatment planning, and ultimately, better outcomes for individuals with these challenging conditions.

What Is the Difference Between ODD and IED Disorder?

Oppositional Defiant Disorder (ODD) and Intermittent Explosive Disorder (IED) are both psychiatric disorders that involve difficulties with impulse control and aggressive behavior. While there’s some overlap between the two conditions, there are also distinct differences that set them apart.

In ODD, aggression is typically characterized by temper tantrums and verbal arguments with authority figures such as parents, teachers, or other adults. Children and adolescents with ODD may often defy rules, intentionally annoy others, and blame others for their own misbehavior. However, their outbursts are often fueled by a desire for control and independence rather than a response to specific provocations.

On the other hand, individuals with IED experience sudden episodes of explosive and uncontrollable rage that are often out of proportion to the situation at hand. These outbursts can be triggered by a broader range of stimuli, including minor frustrations, perceived threats to their territory or personal space, or even perceived insults or slights. In contrast to ODD, the aggressive behavior in IED is more likely to escalate to physical assault directed at others, sometimes resulting in property damage or injury.

The severity of symptoms also differs. ODD is typically diagnosed in childhood or adolescence and tends to improve as individuals age. In contrast, IED often emerges in late adolescence or early adulthood and can persist throughout adulthood if left untreated. Additionally, individuals with IED may experience a greater sense of remorse or guilt after their aggressive outbursts, which isn’t typically observed in ODD.

It’s important to note that ODD and IED can co-occur in some individuals, and there may be shared risk factors or underlying mechanisms that contribute to the development of both disorders. For example, both conditions have been linked to genetic factors, family history of mental health disorders, and disruptions in brain functioning related to impulse control and emotional regulation.

Strategies for Managing Aggression and Impulse Control in Individuals With ODD and IED

  • Implement a structured daily routine
  • Set clear and consistent rules and expectations
  • Provide positive reinforcement for appropriate behavior
  • Teach emotional regulation and coping skills
  • Encourage physical exercise and healthy outlets for anger
  • Use cognitive behavioral therapy techniques
  • Explore medication options with a healthcare professional
  • Provide a safe and calm environment
  • Model and teach problem-solving and conflict resolution skills
  • Support and involve the individual’s family in treatment

Attention-deficit/hyperactivity disorder (ADHD) is often accompanied by disruptive behavior disorders (DBDs) such as oppositional defiant disorder (ODD), conduct disorder (CD), and intermittent explosive disorder (IED). In this resource, primary care clinicians will find a concise overview of these common comorbidities and their relevance to ADHD.

Is IED Comorbid With ADHD?

IED, or intermittent explosive disorder, is a psychiatric disorder characterized by recurrent episodes of explosive outbursts of anger or violence. On the other hand, ODD, or oppositional defiant disorder, is a behavioral disorder marked by a persistent pattern of defiance, disobedience, and hostility towards authority figures.

While there isn’t much research specifically examining the comorbidity between IED and ADHD, it isn’t uncommon for individuals with ADHD to also exhibit symptoms of other disruptive behavior disorders, including ODD and CD. In fact, studies have shown that many children with ADHD have comorbid ODD or CD. This suggests that there may be an overlap between these disorders.

The relationship between ADHD and the comorbid DBDs can be complex. Some research suggests that ADHD may be a risk factor for the development of ODD and CD.

Additionally, the presence of comorbid DBDs has been associated with increased risk for future mental health problems and involvement in criminal behavior.

Early identification and intervention for these comorbidities may help improve outcomes and overall functioning for individuals with ADHD. Collaborating with mental health professionals can be crucial in providing comprehensive care for individuals with ADHD and comorbid DBDs.


However, the odds ratios for these comparisons didn’t differ significantly from each other or from the community sample. This suggests that while there may be a higher prevalence of comorbid diagnoses in individuals with IED and ODD, the specific relationship between these disorders remains unclear.
