DEFINITION
INTERMITTENT EXPLOSIVE DISORDER (IED) is a disorder characterized by recurrent, impulsive, and disproportionate episodes of verbal aggression, physical aggression, property destruction, or assaultive behavior that are grossly out of proportion to the triggering event or psychosocial stressor.
The aggressive episodes are typically rapid in onset, poorly planned, emotionally driven, and followed by varying degrees of remorse, embarrassment, regret, or distress. The aggression is impulsive rather than premeditated and frequently causes substantial impairment in interpersonal, occupational, educational, legal, and social functioning.
Within the SCF-RDOS framework, Intermittent Explosive Disorder is conceptualized as an emotional-threat processing and inhibitory-control disorder involving dysfunction across emotional-regulation systems, aggression-modulation pathways, executive-control networks, threat-appraisal architecture, impulse-inhibition mechanisms, and stress-reactivity circuits.
ETIOPATHOGENIC CORE
Primary Pathogenic Theme
Excessive emotional arousal combined with deficient inhibitory control results in episodic aggressive behavioral discharges that exceed contextual demands and overwhelm adaptive self-regulation mechanisms.
Core Pathogenic Drivers
Domain | Contribution |
Emotional Hyperreactivity | Aggression initiation |
Executive-Control Deficits | Reduced inhibition |
Threat-Appraisal Distortion | Overreaction to stimuli |
Impulse-Control Dysfunction | Behavioral discharge |
Stress-Reactivity Amplification | Escalation of aggression |
Frustration Intolerance | Trigger sensitivity |
Neurobiological Aggression Circuits | Aggressive expression |
Reinforcement Learning Dysregulation | Episode recurrence |

ASSOCIATED CONDITIONS
Intermittent Explosive Disorder commonly overlaps with:
- Impulse Dysregulation Syndrome
- Conduct Disorder
- Oppositional Defiant Disorder
- ADHD
- Substance Use Disorders
- Major Depressive Disorder
- Bipolar Disorder

DIAGNOSTIC CONSIDERATIONS
Core Diagnostic Features
Individuals commonly demonstrate:
- Recurrent impulsive aggressive outbursts
- Aggression disproportionate to provocation

Oppositional Defiant Disorder | Chronic oppositionality predominates |
Personality Disorders | Aggression occurs within broader personality pathology |
Substance-Induced Aggression | Episodes are directly related to intoxication or withdrawal |
