Antisocial personality disorder (ASPD) is a complex mental health condition that affects how a person thinks, feels, and behaves in relation to others. A common misunderstanding is that people with ASPD are always violent or choose crime as a lifestyle. In reality, ASPD exists on a spectrum, and individuals may function in daily life in varying ways. Some may have stable jobs and relationships, while others face substantial legal, social, or occupational challenges. Most importantly, ASPD is a genuine medical condition influenced by a mix of biology, experiences, and environment. With accurate information, compassionate care, and appropriate support, people with ASPD can make meaningful changes in their lives and reduce the impact of symptoms on themselves and others.

What is antisocial personality disorder?

Antisocial personality disorder is a diagnosed pattern of long-standing behavior and inner experience that differs markedly from cultural expectations and causes distress or problems in many areas of life. The core features involve a pervasive pattern of disregard for the rights of others, beginning in adolescence or early adulthood and continuing into adulthood. This pattern is not simply a series of isolated actions; it reflects enduring ways of thinking, feeling, and acting that affect multiple settings such as work, family, and community.

Diagnostic criteria and symptoms

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) outlines criteria used by clinicians to determine a diagnosis of antisocial personality disorder. A diagnosis requires both a pervasive pattern of disregard for the rights of others and at least three of the following symptoms, occurring since age 15 and continuing into adulthood, with evidence of conduct disorder with onset before age 15:

  • Failure to conform to social norms with respect to lawful behaviors, as indicated by repeatedly performing acts that are grounds for arrest.
  • Deceitfulness, indicated by repeated lying, use of aliases, or conning others for personal gain or pleasure.
  • Impulsivity or failure to plan ahead.
  • Irritability and aggressiveness, as shown by repeated physical fights or assaults.
  • Reckless disregard for the safety of self or others.
  • Consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations.
  • Lack of remourse, as evidenced by indifference to or rationalization of hurting, exploiting, or lying to others.
  • The individual is at least 18 years old, and the conduct disorder symptoms before age 15 have been present.

It is important to recognize that the presence of several of these symptoms does not automatically mean ASPD. A qualified mental health professional conducts a careful assessment that considers the person’s history, functioning across settings, and any co-occurring conditions. The aim of diagnosis is to guide treatment and support, not to label or stigmatize.

Prevalence and demographics

ASPD is relatively uncommon in the general population, but it is more frequently identified among certain groups and settings. Estimates vary, but in many community samples, prevalence is modest—roughly around 1% or less of the adult population, with higher estimates for men and for individuals who have histories of conduct problems in childhood. Among incarcerated populations, rates of ASPD are substantially higher, reflecting overlapping risk factors and pathways such as early behavioral issues, substance use, and social adversity.

Gender patterns are observed in many studies, with ASPD diagnosed more often in men than in women. However, researchers emphasize that manifestations can differ by gender, and women with ASPD may be underdiagnosed or diagnosed later due to differing presentations and sociocultural expectations. It is also common for ASPD to co-occur with other mental health conditions, including substance use disorders, anxiety, and mood disorders, which can influence both prevalence estimates and how symptoms present.

Causes and risk factors

ASPD arises from a mix of biological, psychological, and environmental factors. It is not caused by a single factor, and many people with risk factors do not develop ASPD. Key areas of influence include:

  • Genetics and biology: Family history and genetic factors can contribute to temperament, impulse control, and susceptibility to certain behaviors. Some neurobiological differences, such as patterns of brain activity related to emotion regulation and reward processing, have been explored in research related to ASPD.
  • Early experiences and environment: Adverse childhood experiences—such as abuse, neglect, household dysfunction, or chronic stress—can shape behavioral patterns and coping strategies. Growing up in environments with limited access to positive guidance, stable role models, or consistent discipline may increase risk.
  • Temperament and social learning: Early patterns of difficulty with frustration tolerance, impulse control, and forming secure attachments can interact with social learning—how a person learns to respond to others and to rewards or consequences.
  • Substance use and comorbidity: Substance use disorders often co-occur with ASPD and can exacerbate symptoms such as impulsivity and aggression. Treating co-occurring conditions is an important part of care.

While these factors can raise risk, they do not determine fate. Many people with risk factors can develop healthy coping strategies, supportive relationships, and meaningful work with appropriate interventions and supports.

The diagnosis process

Diagnosing ASPD involves careful clinical evaluation by a qualified mental health professional. The process typically includes multiple steps to gather a complete picture of the person’s life, behavior, and functioning:

  • Clinical interview: A clinician asks about behavior patterns, thoughts, feelings, relationships, and daily functioning across different settings and over time.
  • Developmental history: Information about childhood conduct, family environment, and significant life events helps determine whether conduct disorder symptoms began before age 15.
  • Collateral information: When possible, information from family members, schools, or previous clinicians can provide important context and corroboration.
  • Medical evaluation: A check for medical or neurological conditions that could mimic or contribute to behavioral changes is important to rule out other causes.
  • Use of standardized instruments: Clinicians may employ structured interviews or checklists designed for personality disorders to increase reliability and consistency in diagnosis, such as DSM-5-TR criteria or other validated tools.

Because ASPD is a personality disorder reflecting long-standing patterns, diagnosis generally requires observations over time and across different situations. If you are seeking an assessment for yourself or someone you care about, starting with a primary care physician who can refer you to a qualified mental health professional is a good first step.

Treatment approaches

There is no cure for antisocial personality disorder, but effective treatment focuses on reducing harmful behaviors, increasing safety, improving functioning, and supporting healthier relationships. Treatment plans are highly individualized and may require a combination of therapy, support services, and, when appropriate, medications for co-occurring conditions.

Therapy and behavioral interventions

Evidence-based therapies for ASPD emphasize structure, accountability, and developing skills that support safer and more adaptive behavior. Key approaches include:

  • Cognitive-behavioral therapy (CBT): CBT helps individuals recognize problematic thought patterns, test new ways of reacting to situations, and practice alternative responses. It often includes skill-building in impulse control, problem solving, and social interactions.
  • Contingency management and behavioral programs: In some settings (especially for those with substance use issues or in community programs), structured reinforcement for prosocial behavior and adherence to treatment can support change.
  • Social skills training and anger management: Teaching effective communication, empathy, and strategies to manage anger can reduce aggression and improve relationships.
  • Dialectical behavior therapy (DBT) adaptations: While DBT was developed for other conditions, its emphasis on emotion regulation, distress tolerance, and interpersonal effectiveness can be helpful for some individuals with ASPD, especially when there is co-occurring mood or anxiety symptoms.
  • Family-involved and group therapies: When appropriate, involving trusted family members or peers in therapy can provide support, feedback, and accountability within a safe framework.

Therapy for ASPD can be challenging, and progress may be gradual. A strong therapeutic alliance, realistic goals, and consistency are important contributors to positive outcomes. Treatment success is often linked to the presence of a stable supportive environment and engagement in ongoing care.

Medication and managing co-occurring conditions

There is no medication that treats ASPD itself. Instead, medications are typically used to address co-occurring or related symptoms and conditions, such as mood disorders, anxiety, attention problems, or aggressive behavior. Common considerations include:

  • Antidepressants (e.g., SSRIs) for co-occurring depression or anxiety.
  • Mood stabilizers or antipsychotic medications in cases of significant impulsivity or aggression, when clinically indicated and carefully monitored by a clinician.
  • Medications for attention problems (if present) such as stimulant or non-stimulant therapies for ADHD symptoms.
  • Substance use treatments, including medications that support sobriety and reduce cravings, when there is a concurrent substance use disorder.

Medication decisions depend on the individual’s full clinical picture, possible interactions with other drugs, and careful monitoring for side effects. A psychiatrist or other prescriber can discuss benefits, risks, and goals in collaboration with the person and their care team.

Living well with antisocial personality disorder

Living well with ASPD is a realistic goal for many people, especially when care is ongoing, supports are in place, and strengths are leveraged. Practical strategies that can help include:

  • Developing a stable routine: Regular sleep, meals, work or school activities, and structured daily patterns create predictable environments that can reduce impulsivity and stress.
  • Engaging in meaningful activity: Employment, volunteering, or education can provide purpose, accountability, and opportunities for positive social interactions in safe settings.
  • Healthy relationships and boundaries: Clear communication, boundaries, and seeking support from trusted individuals or groups can help maintain safety and reduce conflict.
  • Substance use treatment and relapse prevention: If alcohol or drugs are involved, participating in evidence-based treatments and aftercare reduces risks and supports recovery.
  • Mindfulness and stress management: Techniques for managing anger, frustration, and strong emotions can improve decision-making and self-control.
  • Education and self-awareness: Learning about ASPD, recognizing personal triggers, and collaborating with clinicians fosters proactive participation in care.
  • Accessible support networks: Support groups, peer support, and community mental health services can provide encouragement and reduce isolation.

Support for families and caregivers is also important. Understanding ASPD, setting consistent boundaries, and seeking guidance from clinicians can help reduce strain and improve communication within households.

Where to seek help and additional resources

If you or someone you know may have antisocial personality disorder, consider speaking with a qualified mental health professional for an assessment and personalized care plan. Helpful, evidence-based information can be found at reputable organizations and medical sites:

These resources offer explanations of symptoms, diagnostic criteria, and guidance on treatment options. A clinician can tailor information to an individual’s needs, including considerations for culture, age, and co-occurring conditions.

If you are a family member or caregiver, you may also benefit from seeking support for yourself. Caring for someone with ASPD can be challenging, and professional guidance can help you set boundaries, manage stress, and maintain safety for everyone involved.
