What Is Antisocial Personality Disorder? Symptoms, Causes, Diagnosis, Treatment

In popular culture, people with antisocial personality disorder (ASPD) are often referred to as sociopaths,a term that conjures up images of mass murderers or creepy thrillers about highly manipulative individuals who thrive on hurting other people.

While there are people with antisocial personality disorder who fit those stereotypes, and while a very high percentage of violent offenders in prison have antisocial personality disorder, the American Psychiatric Association (APA) does not refer to people with antisocial personality disorder as sociopaths, nor does it equate the two terms.

Personality disorders are conditions involving long-term patterns in which a persons feelings, self-perception, and behavior stray substantially from the norms of their society and culture.

An estimated 9 percent of U.S. adults have a personality disorder diagnosis, according to the National Institute of Mental Health. (1) And an estimated 3.6 to 4.3 percent of people in the United States have the mental health condition known as antisocial personality disorder, according to research. (2,3)

A defining trait of antisocial personality disorder is a lack of empathy and a disregard for others, generally. A person with antisocial personality disorder has little concern for other people and is willing to violate their rights. They usually have no respect for social norms and laws and may believe they are above the law.They will frequently lie, manipulate other people, and may risk the health or lives of other people. And they do not feel any guilt or remorse for these actions. (4)

Nonetheless, millions of people with the condition live mostly normal-looking lives. But while they may not commit violent crimes or even break the law, they most likely use others for their gain or have no problem hurting others.

Signs and Symptoms of Antisocial Personality Disorder

Early symptoms of antisocial personality disorder may show up in childhood or adolescence. Behaviors before age 18 that are associated with a later diagnosis of antisocial personality disorder include:

  • Showing cruelty to animals
  • Intentionally setting fires
  • Frequently breaking rules for no obvious reason
  • Bullying
  • Stealing
  • Engaging in vandalism
  • Having difficulty making friends

In adulthood, people with antisocial personality disorder may intentionally harm others and show no evidence of guilt or remorse for the harm they cause. Other behaviors associated with the disorder include:

  • Frequently lying
  • Acting impulsively
  • Flattering others to gain something
  • Frequently getting in fights
  • Committing physical or sexual assault
  • Expressing pleasure in otherssuffering

Causes and Risk Factors of Antisocial Personality Disorder

The cause of ASPD is unknown, but certain genetic and environmental factors are thought to increase the likelihood of a person having it. (5) Risk factors include:

  • History of child abuse
  • Parent with a drug or alcohol dependence disorder
  • Parent with antisocial personality disorder (4)
  • Family conflict
  • Mutations in one’s genes
  • Poverty (6)

How Is Antisocial Personality Disorder Diagnosed?

There is no blood test, brain scan, or other objective test that can be used to diagnose antisocial personality disorder. Like nearly all mental health conditions, antisocial personality disorder is diagnosed by meeting criteria laid out in the Diagnostic and Statistical Manual of Mental Disorders. The most recent edition is the fifth (DSM-5), published in 2013.

The clinician will evaluate a person by asking a series of questions about their symptoms, including how long those symptoms have existed and how severe they are. (5)

The DSM-IV criteria required a person to be at least 18 years old and have shown evidence of conduct disorder before age 15. They would show disregard for and violation of the rights of othersby demonstrating at least three of seven behaviors, including harming others, lying, breaking rules, and lacking remorse. They would also show this behavior outside of any possible schizophrenia or bipolar disorder diagnosis.

The current criteria in the DSM-5 are more complex and nuanced. They require evidence of serious deficits in a persons personality and in their relationships with other people. The DSM-5 also requires them to show manipulativeness, intentional dishonesty, no regard for others, and aggression or hostility toward others.

People with antisocial personality disorder show these characteristics across time and different situations, and these behaviors do not result from their social circumstances, the physical effects of substance use, or another mental disorder or medical condition.

The Antisocial Personality Disorder Test?

Just as there’s no diagnostic blood work or imaging for ASPD, there’s no test one can take to determine whether they have ASPD. Search the internet, though, and you’ll find ASPD “tests” or questionnaires about your personality, based on the criteria that mental health professionals use to help diagnose ASPD. These tests generally caution that they’re only for ”educational” purposes and cannot take the place of a psychological evaluation by a mental health professional.

Can Children Have Antisocial Personality Disorder?

Children can exhibit antisocial behaviors, and signs of the disorder typically begin in childhood or the early teen years, but a person cannot be diagnosed with antisocial personality disorder until they are at least 18 years old. (4) People who show symptoms of antisocial personality disorder before age 18 are usually diagnosed with conduct disorder.

Duration of Antisocial Personality Disorder

Because ASPD is challenging to treat, it’s hard to gauge how the condition may improve over time. Personality disorders are lifelong patterns of behavior and there’s no cure for ASPD. Still, ASPD symptoms tend to peak during late adolescence and one’s late twenties. By one’s forties, symptoms may improve or lessen on their own. Aggressive and criminal behaviors, in particular, may decrease with age. (5,7)

Treatment Options for Antisocial Personality Disorder

Antisocial personality disorder is extremely difficult to treat, largely because people who have it often do not seek out or want treatment. Sometimes a court will order a person to receive treatment.

Behavioral treatments that reward socially acceptable behavior and provide negative consequences for illegal or inappropriate behavior can be partly effective. Talk therapy is another option for people with antisocial personality disorder. (5)

Often, a person with antisocial personality disorder will have other conditions that require treatment, such as a substance use disorder or another mental health condition. (5)

For people who have committed violent crimes, imprisonment can reduce the harm they can cause to others. But research has shown that violent offenders with antisocial personality disorder have a hard time learning from their mistakes and do not respond to punishment. They can have poorer working memory and are often unable to change their behavior even after being shown what the consequences will be. (8)

It is unclear whether or not people with antisocial personality disorder have the potential for empathy. Some research suggests that they can feel empathy but may need to switch it on, in a sense, suggesting a possible avenue of future research for treatment. (9)

Is Antisocial Personality Disorder Preventable?

No, there’s currently no way to prevent ASPD, although societal changes to reduce risk factors, such as poverty and child abuse, could help in reducing the number of people with this disorder. Early detection and intervention may also help reduce the severity of this disorder and the harm this condition can cause family and friends. (7)

Complications of Antisocial Personality Disorder

Antisocial personality disorder is directly linked to breaking rules and criminal behavior, so people with this personality disorder are at high risk for committing crimes and serving prison time. They have a higher risk for committing violence against others, but ASPD is also linked to self-harm, as those with the disorder have higher risk for dying by suicide, and for dying from accidents or violence related to their actions. (5,7)

They also have a higher risk for using illegal drugs or developing dependence on drugs, alcohol, or other substances. (10)

Research has shown a higher risk of physical health problems among people with antisocial personality disorder, including heart disease, gastrointestinal disease, liver disease, arthritis, overall disability, emergency department visits, and hospitalizations. (1,11)

People with antisocial personality disorder are more likely to experience divorce or other separation from their spouse, homelessness, unemployment, and financial dependence on others or on government programs. (12)

Research and Statistics: Who Has Antisocial Personality Disorder?

There appears to be a large gender difference in terms of who is likely to be diagnosed with ASPD, with men at a significantly higher rate. (5) Two studies suggested that about 4.5 or 6.8 percent of men have antisocial personality disorder, while both estimated that 0.8 percent of women have it. Lower estimates have been found in European studies, with ASPD in approximately 3 percent in men and up to 1 percent in women. (13)

When compared with society as a whole, people in prison are much more likely to have ASPD. One study which looked at the prison population worldwide estimated that 47 percent of incarcerated men and 21 percent of women have antisocial personality disorder. (13)

Related Conditions of Antisocial Personality Disorder

People with antisocial personality disorder are more likely to have depression or an anxiety disorder than the general population, particularly among women with antisocial personality disorder. (14) Other mental health conditions more common in people with antisocial personality disorder include post-traumatic stress syndrome, borderline personality disorder, bipolar disorder, and schizophrenia-related disorders.
