Intermittent Explosive Disorder (IED) is a mental disorder characterized by recurrent violent behavior. Refining diagnostic criteria can improve recognition and management of IED and related impulsive behaviors in psychiatric patients.

Area of Science:

  • Psychiatry
  • Neuroscience
  • Behavioral Science

Context:

  • Intermittent Explosive Disorder (IED) is a recently defined mental disorder with evolving diagnostic criteria.
  • Ambiguities persist, particularly regarding its distinction from personality disorders like antisocial and borderline personalities.
  • Violent behavior and impulsivity are common in psychiatric patients, yet IED remains understudied.

Purpose:

  • To review the current understanding of Intermittent Explosive Disorder (IED), including its diagnostic challenges and clinical presentation.
  • To explore the comorbidity, potential etiopathogenesis, and treatment of IED.
  • To emphasize the need for refined diagnostic criteria for better recognition and management of IED.

Summary:

  • IED is characterized by recurrent, impulsive aggressive outbursts. Diagnostic criteria are evolving, with discussions on excluding or including comorbid personality disorders.

  • Key diagnostic features include preceding tension and subsequent release/pleasure, common in other impulse control disorders.
  • IED is more prevalent in adolescents and males, with low reported prevalence due to strict criteria. High comorbidity exists with mood, anxiety, and cluster B personality disorders.
  • Etiopathogenic factors may involve serotonergic system deregulation and mild brain injuries, influencing treatment with SSRIs, mood stabilizers, and beta-blockers.
  • Current treatment efficacy is largely based on case reports, necessitating controlled trials.

    • Impact:

    • Refined diagnostic criteria for IED can lead to better categorization of violent behaviors across various psychiatric conditions.
    • Improved recognition and management strategies for patients exhibiting violent and impulsive behaviors.
    • Further research into IED's etiopathogenesis and treatment efficacy is crucial for clinical practice.
