Antisocial personality disorder (ASPD) is defined by the American Psychiatric Associations Axis II (personality disorders) of the Diagnostic and Statistical Manual (DSM-IV-TR) as a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood. Antisocial personality disorder is sometimes wrongly referred to as psychopathy or sociopathy. Currently, neither psychopathy nor sociopathy are valid diagnoses described in the Diagnostic and Statistical Manual of Mental Disorders, and the ICD-10 of the World Health Organization also lacks psychopathy as a diagnostic disorder. Psychopathy is normally seen as a subset of the antisocial personality disorder, but Blair believes that the antisocial personality disorder and psychopathy may be separate conditions altogether.
