Intermittent explosive disorder (IED)

Intermittent explosive disorder (IED) is a mental health condition characterized by sudden episodes of intense anger and aggressive behavior that are disproportionate to the situation. It primarily affects the brain's emotional regulation system, leading to difficulty controlling impulses and reactions. People with IED may experience repeated outbursts of verbal or physical aggression, which can harm relationships and cause legal or social problems. These episodes are not planned and often occur with little warning. The disorder impacts overall well-being by increasing stress and impairing social and occupational functioning. Understanding and recognizing these explosive episodes is important for managing the condition.

Intermittent explosive disorder (IED) is a psychiatric diagnosis characterized by recurrent, discrete episodes of failure to resist aggressive impulses resulting in serious assaultive acts or destruction of property. The core pathology involves dysregulation of impulse control and emotional regulation, often linked to abnormalities in serotonergic and dopaminergic neurotransmission within the brain. The disorder typically manifests in late adolescence or early adulthood and is associated with significant distress or impairment in social, occupational, or legal domains. IED is distinct from other psychiatric disorders by the impulsive, unpremeditated nature of the aggressive outbursts. It is important to differentiate IED from aggression due to other medical or substance-related causes. The disorder's major clinical significance lies in its potential for causing harm to self or others and its association with comorbid conditions such as mood and anxiety disorders.
