From the Guidelines
Intermittent Explosive Disorder (IED) is characterized by repeated brief episodes of verbal or physical aggression or destruction of property, representing a failure to control aggressive impulses.
Diagnosis
- The diagnosis of IED is based on the presence of repeated brief episodes of verbal or physical aggression or destruction of property, as described in the study 1.
- The episodes must represent a failure to control aggressive impulses, and must not be better explained by another mental disorder or a general medical condition.
Treatment
- While the study 1 does not provide specific treatment options for IED, treatment typically involves a combination of psychotherapy and medication, such as selective serotonin reuptake inhibitors (SSRIs) or mood stabilizers, to help manage symptoms and reduce aggressive impulses.
- Cognitive-behavioral therapy (CBT) is also a commonly used treatment approach for IED, as it helps individuals identify and change negative thought patterns and behaviors that contribute to their aggressive outbursts.
- It is essential to note that the study 1 provides a description of IED, but does not offer specific treatment guidelines, highlighting the need for further research and clinical guidance in this area.
From the Research
Diagnosis of Intermittent Explosive Disorder (IED)
- IED is characterized by recurrent, problematic impulsive aggressive behavior 2
- The disorder is associated with several cognitive and affective impairments, including emotion dysregulation, impulsive tendencies, and aggression severity 3
- Diagnostic criteria for IED have been developed and refined over time, with recent research criteria better identifying individuals with elevated levels of aggression, impulsivity, and abnormalities in neurobiological markers of aggression 4
Treatment of Intermittent Explosive Disorder (IED)
- Research suggests that interventions targeting serotonergic signaling may be effective in treating IED, given the role of the amygdala and orbitofrontal cortex in emotional regulation and impulse control 5
- A personalized therapeutic approach may be necessary, given the heterogeneity of IED and the distinct cognitive-affective symptom profiles among individuals with the disorder 3
- Further research is needed to develop more effective interventions for IED, including studies on the genetics underlying aggression and the development of consistently defined IED as a phenotype 5
Etiology and Neurobiology of Intermittent Explosive Disorder (IED)
- IED is thought to have a multifactorial etiology, with contributions from childhood trauma, adverse family environment, and genetic factors 5
- The amygdala and orbitofrontal cortex play a crucial role in emotional regulation and impulse control, and abnormalities in these regions may contribute to the development of IED 5
- Research on the genetics of IED is limited, and further studies are needed to understand the underlying mechanisms and develop more effective interventions 5
