Antisocial personality disorder is characterized by a disregard for social norms and the rights of others since age 15, as demonstrated by behaviors such as failure to conform to social norms, deceitfulness, impulsivity, irritability and aggression, recklessness, irresponsibility, and lack of remorse. The disorder typically follows a chronic unremitting course, with symptoms peaking in late adolescence. Common comorbid conditions include substance abuse disorders and depressive disorders. Treatment may involve psychotherapy, though patients often respond better in peer settings rather than isolation. Pharmacotherapy can also be used to treat comorbid conditions like anxiety, rage, and depression.
