It is a disorder that helps impair dramatic, emotional, or erratic disorders, also known as cluster B disorders. Cluster B disorders also include borderline personality disorder, narcissistic personality disorder, and histrionic personality disorder.

They describe the symptoms of antisocial personality disorder as: possessing charm, readily able to manipulate the emotions of others, pattern of criminal behavior, disregard for the safety of oneself or others, problems with lying, stealing and fighting, and lack of sense of guilt (National Institute of Health, 2012). The DSM-5 (American Psychiatric Association, 2013) also states that individuals with antisocial personality disorder may be irresponsible, which hinders their ability to obtain or keep a job. They also cite lack of empathy, self-confidence, aggression, and sexual and high-risk substance use as additional symptoms.
