Abstract

Impulsive aggression is characterized by an inability to regulate affect as well as aggressive impulses, and is highly comorbid with other mental disorders including depression, suicidal behavior, and substance abuse. In an effort to elucidate the neurobiological underpinnings of impulsive aggression and to help account for its connections with these other disorders, this paper reviews relevant biochemical, brain imaging, and genetic studies. The review suggests that dysfunctional interactions between serotonin and dopamine systems in the prefrontal cortex may be an important mechanism underlying the link between impulsive aggression and its comorbid disorders. Specifically, serotonin hypofunction may represent a biochemical trait that predisposes individuals to impulsive aggression, with dopamine hyperfunction contributing in an additive fashion to the serotonergic deficit. The current paper proposes a modified diathesis-stress model of impulsive aggression in which the underlying biological diathesis may be deficient serotonergic function in the ventral prefrontal cortex. This underlying disposition can be manifested behaviorally as impulsive aggression towards oneself and others, and as depression under precipitating life stressors. Substance abuse associated with impulsive aggression is understood in the context of dopamine dysregulation resulting from serotonergic deficiency. Also discussed are future research directions in the neurobiology of impulsive aggression and its comorbid disorders.

  • Alcohol can further suppress prefrontal inhibitory processes while potentiating limbic activation, creating a vicious cycle wherein aggression and heavy drinking reinforce one another.

    “Alcohol can further suppress prefrontal inhibitory processes while potentiating limbic activation, creating a vicious cycle wherein aggression and heavy drinking reinforce one another (Seo et al. 2008; Heinz et al. 2011).”

    From Decoding the bidirectional links between alcohol misuse and aggression: toward a unified translational framework (2026) · cites this paper as Seo et al. 2008

    In “Substance Abuse and Impulsive Aggression” (page unavailable), the paper links prefrontal dysfunction, elevated limbic dopamine activity, and poor inhibition with substance abuse and impulsive aggression, particularly in type II alcoholism. It does not establish that alcohol itself further suppresses prefrontal inhibition or potentiates limbic activation, or that aggression and heavy drinking form a reciprocal reinforcing cycle. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • These circuits are modulated by serotonergic and dopaminergic dysfunction: serotonin deficits are associated with impulsive aggression, while dopamine dysregulation drives increased reward sensitivity and dysregulated motivational drive toward substance use.

    “These circuits are further modulated by serotonergic and dopaminergic dysfunction: serotonin deficits are associated with impulsive aggression, while dopamine dysregulation drives increased reward sensitivity and dysregulated motivational drive toward substance use (Seo et al. 2008; Gan et al. 2015b).”

  • Dopamine neuronal cell bodies and axon terminals are modulated by 5-HT and receive extensive projections from these neurons.

    “As evident in past studies, DA neuronal cell bodies and axon terminals are modulated by 5-HT and receive extensive projections from these neurons (54).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
