The cause of this disorder is unknown, but biological or genetic factors may play a role. The incidence of antisocial personality is higher in people who have an antisocial biological parent. Although the diagnosis is limited to those over 18 years of age, there is usually a history of similar behaviors before age 15, such as repetitive lying, truancy, delinquency, and substance abuse. This disorder tends to occur more often in men and in people whose predominant role model had antisocial features.
