Antisocial personality disorder (ASPD or APD) is a personality disorder characterized by a long term pattern of disregard for, or violation of, the rights of others. A low moral sense or conscience is often apparent, as well as a history of crime, legal problems, or impulsive and aggressive behavior.[3][4]

Antisocial personality disorder (ASPD or APD) is a personality disorder characterized by a long term pattern of disregard for, or violation of, the rights of others. A low moral sense or conscience is often apparent, as well as a history of crime, legal problems, or impulsive and aggressive behavior.^[3][4]
Antisocial personality disorder is defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Dissocial personality disorder (DPD), a similar or equivalent concept, is defined in the International Statistical Classification of Diseases and Related Health Problems (ICD), which includes antisocial personality disorder in the diagnosis. Both manuals provide similar criteria for diagnosing the disorder.^[5] Both have also stated that their diagnoses have been referred to, or include what is referred to, as psychopathy or sociopathy, but distinctions have been made between the conceptualizations of antisocial personality disorder and psychopathy, with many researchers arguing that psychopathy is a disorder that overlaps with, but is distinguishable from, ASPD.^{[6][7][8][9][10]}
