Antisocial Personality Disorder

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A personality disorder marked by a pervasive pattern of disregard for and violation of the rights of others.

Overview

Antisocial personality disorder involves a long-standing pattern of disregard for the rights of others, beginning by adolescence and continuing into adulthood, and is diagnosed only in adults.

Signs and Symptoms

Signs can include repeated unlawful behavior, deceitfulness, impulsivity, irritability, disregard for the safety of others, consistent irresponsibility, and lack of remorse. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

The exact cause is not fully understood. Genetic factors, early conduct problems, and adverse childhood experiences are each associated with increased risk.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Specialized psychotherapy approaches may be considered, though engagement in treatment can be a challenge and evidence for specific approaches is more limited than for some other conditions.

Living With Antisocial Personality Disorder

Treatment often focuses on reducing harmful behaviors and addressing co-occurring conditions such as substance use.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Emergency Situations

If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.

Outlook

The course varies; some features may lessen with age, though the disorder can be associated with significant interpersonal and legal difficulties over time.
