Personality disorders are long-term (chronic) patterns of behaviors and relationships that interfere with a person's life over many years.

The cause of antisocial personality disorder is unknown. 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. The condition is common in prison populations.

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