Antisocial personality disorder is a psychiatric condition characterized by chronic behavior that manipulates, exploits, or violates the rights of others. This behavior is often criminal.

Personality disorders are chronic behavioral and relationship patterns that interfere with a person's life over many years. To receive a diagnosis of antisocial personality disorder, a person must have exhibited behavior that qualifies for a diagnosis of conduct disorder during childhood.

The cause of antisocial personality disorder is unknown, but genetic factors and child abuse are believed to contribute to the development of this condition. People with an antisocial or alcoholic parent are at increased risk. Far more men than women are affected, and unsurprisingly, the condition is common in prison populations.

Fire-setting and cruelty to animals during childhood are linked to the development of antisocial personality.

A person with antisocial personality disorder:

• Breaks the law repeatedly
• Lies, steals, and fights often
• Disregards the safety of self and others
• Demonstrates a lack of guilt
• Had a childhood diagnosis (or symptoms consistent with) conduct disorder

Individuals with antisocial personality disorder are often angry and arrogant, but may be capable of superficial wit and charm. They may be adept at flattery and manipulating the emotions of others. People with antisocial personality disorder often have extensive substance abuse and legal problems.
