Antisocial personality disorder is characterised by a pattern of disregard for and violation of the rights of others.
The diagnosis of antisocial personality disorder is not given to individuals under the age of 18 but is given only if there is a history of some symptoms of conduct disorder before age 15.
The symptoms of antisocial personality disorder can vary in severity. The more egregious, harmful, or dangerous behaviour patterns are referred to as sociopathic or psychopathic.
