Antisocial personality disorder, alcohol, and aggression

Area of Science:

• Neuroscience
• Psychiatry
• Behavioral Science

Background:

• Alcohol consumption is consistently associated with increased aggression in epidemiological and laboratory studies.
• However, not all individuals display heightened aggression when under the influence of alcohol.
• Antisocial personality disorder (ASPD) is increasingly recognized as a potential moderator of alcohol's effects on aggression.

Purpose of the Study:

• To investigate the relationship between antisocial personality disorder (ASPD) and alcohol-related aggression.
• To explore potential biological and other contributing factors to this association.

Main Methods:

• Review of existing epidemiologic studies and laboratory research findings.
• Comparison of aggressive behavior and alcohol dependence rates between individuals with and without ASPD.
• Analysis of potential neurobiological underpinnings, including neurotransmitter function and executive brain region activity.

Main Results:

• Individuals with ASPD exhibit higher rates of alcohol dependence and alcohol-related problems compared to those without ASPD.
• Laboratory studies demonstrate greater increases in aggressive behavior following alcohol consumption in individuals with ASPD.
• The association may be linked to impairments in serotonin pathways or executive brain functions characteristic of ASPD.

Conclusions:

• ASPD is associated with a heightened propensity for alcohol-related aggression.
• Biological factors, such as neurochemical imbalances or executive dysfunction, may underlie this association.
• Further research is needed to fully elucidate the undetermined factors contributing to general aggression risk in ASPD.
