The cause of this disorder is unknown. A person's genes and other factors, such as child abuse, may contribute to developing this condition. People with an antisocial or alcoholic parent are at increased risk. Far more men than women are affected. The condition is common among people who are in prison.

Setting fires and animal cruelty during childhood are often seen in the development of antisocial personality.

Some health care providers believe that psychopathic personality (psychopathy) is the same disorder. Others believe that psychopathic personality is a similar, but a more severe disorder.

A person with antisocial personality disorder may:

• Be able to act witty and charming
• Be good at flattery and manipulating other people's emotions
• Break the law repeatedly
• Disregard the safety of self and others
• Have problems with substance abuse
• Lie, steal, and fight often
• Not show guilt or remorse
• Often be angry or arrogant

Antisocial personality disorder is diagnosed based on a psychological evaluation. The provider will consider how long-lived and how severe the person's symptoms are. To be diagnosed with antisocial personality disorder, a person must have had emotional and behavioral problems (conduct disorder) during childhood.

Antisocial personality disorder is one of the hardest personality disorders to treat. People with this condition usually don't seek treatment on their own. They may only start therapy when required to by a court.

Behavioral treatments, such as those that reward appropriate behavior and have negative consequences for illegal behavior, may work in some people. Talk therapy may also help.

People with an antisocial personality who have other disorders, such as a mood or substance use disorder, are often treated for those problems as well.

Symptoms tend to peak during the late teenage years and early 20s. They sometimes improve on their own by the time a person is in their 40s.

Complications may include imprisonment, misuse of prescription or over-the-counter medicines, illegal drugs, alcohol, violence, and suicide.
