I don't have formal training, but as I understand it, the formal Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnosis is "antisocial personality disorder" (https://en.wikipedia.org/wiki/Antisocial_personality_disorde...).

See also https://en.wikipedia.org/wiki/Psychopathy_or_sociopathy and in general also note the WHO's International Statistical Classification of Diseases and Related Health Problems (ICD), which could be a less intensely political artifact than the US DSM.
