Antisocial personality disorder
Antisocial personality disorder (APD or ASPD) is a psychiatric diagnosis that interprets antisocial and impulsive behaviours as symptoms of a personality disorder. Psychiatry defines only pathological antisocial behavior; it does not address potential benefits of positive antisocial behavior or define the meaning of 'social' in contrast to 'antisocial'.
