Pervasive disregard for and violation of the rights of others since age 15, with conduct disorder before age 15.
Also known as: ASPD, antisocial personality disorder, sociopathy
Overview
A Cluster B personality disorder marked by a pervasive pattern of disregard for and violation of the rights of others since age 15, diagnosed in individuals >=18 with evidence of conduct disorder onset before age 15.
Epidemiology
Lifetime prevalence ~1-4%; substantially higher in incarcerated populations (~40-70%). Male predominance ~3:1. Onset childhood/adolescence with often attenuating antisocial acts by mid-life, though core traits persist.

Lower socioeconomic status, exposure to community violence
Comorbid ADHD in childhood
Substance use disorders
Pathophysiology
Heritable callous-unemotional traits with reduced amygdala reactivity to distress cues, impaired fear conditioning, and prefrontal dysfunction. Low resting heart rate and reduced autonomic reactivity in childhood are early markers.
Clinical presentation
Symptoms
>=3 of 7 criteria since age 15: failure to conform to social/legal norms (arrests); deceitfulness (lying, conning); impulsivity; irritability and aggressiveness (fights, assaults); reckless disregard for safety of self/others; consistent irresponsibility (work, finances); lack of remorse
Conduct disorder onset before age 15 (aggression to people/animals, destruction of property, deceitfulness/theft, serious rule violations)
Signs / physical exam
Charm without empathy; superficial affect
Forensic history, tattoos in some cultural contexts (not diagnostic)
Substance use comorbidity is the rule, not exception
Differential diagnosis
Substance use disorder alone — Antisocial behavior limited to acquiring/using substances; pattern remits with abstinence
Narcissistic personality disorder — Grandiosity and need for admiration without aggression or law-breaking
Borderline personality disorder — Self-directed harm and identity disturbance predominate; less predatory
Intermittent explosive disorder — Discrete aggressive outbursts disproportionate to provocation; otherwise normal interpersonal functioning
Conduct disorder — Same behavioral profile in <18 years old; ASPD requires >=18
Adult ADHD — Impulsivity without callousness or deceit
Diagnostic workup
Diagnostic criteria
DSM-5-TR: (A) >=3 of 7 antisocial criteria since age 15; (B) >=18 years old; (C) Conduct disorder with onset before age 15; (D) Antisocial behavior not exclusively during schizophrenia or bipolar episodes. Psychopathy Checklist-Revised (PCL-R) measures related but narrower construct of psychopathy.

Treatment
First-line
Treat comorbid substance use disorder — often the most modifiable contributor to behavior
Treat comorbid depression, anxiety, and ADHD; avoid stimulants and benzodiazepines when possible
Cognitive behavioral interventions in structured settings (e.g., correctional programs) show modest effect on recidivism
Contingency management; supervised community programs
Safety planning for clinicians; clear limits
Second-line / adjunct
No FDA-approved pharmacotherapy for ASPD itself
Mood stabilizers or atypical antipsychotics may reduce aggression
Family/partner support and child protective involvement when relevant
Recognize limits of intervention with patients who do not perceive a problem
Complications
Premature mortality from violence, accidents, suicide, substance use
Incarceration, unemployment, family disruption
Substance use disorders, comorbid ADHD
Victimization of family members and intimate partners
Iatrogenic harm from manipulation of healthcare systems for opioids/benzodiazepines
PANCE pearls
Childhood conduct disorder is required — without evidence of pre-15 antisocial behavior, the diagnosis cannot be made.
Antisocial behavior limited to substance acquisition does NOT establish ASPD; reassess after sustained abstinence.
Psychopathy (PCL-R) is a narrower construct emphasizing callous-unemotional traits and predicts violence risk better than ASPD diagnosis alone.
Maintain clear boundaries and avoid prescribing controlled substances; document carefully.
