It is termed antisocial personality disorder in the diagnostic and statistical manual and dissocial personality disorder in the International Classification of Diseases. However, some authors query the ability of the existing manuals to identify a special category termed 'psychopathy', which in their opinion deserves special attention. On treatment-related issues, many psychological and behavioural therapies have shown success rates ranging from 25% to 62% in different cohorts. Multisystemic therapy and cognitive behaviour therapy have been proven efficacious in many trials. There is no substantial evidence for the efficacy of pharmacological therapy. Currently, the emphasis is on early identification and prevention of antisocial behaviour despite the ethical implications of defining at-risk children.Further research is needed in the areas of neuroendocrinological associations of violent behaviour, taxonomic existence of psychopathy and efficacy of treatment modalities.The concept of a personality disorder with callousness and unemotionality plus disregard for social norms is well established in psychiatry [1]. Such people share a combination of traits that may include violence, aggression, callousness, lack of empathy and repeated acts of criminality against social norms. However, the classifications and definitions from this point onward are not clear.Though such traits would have existed in human societies from time immemorial, identifying and classifying such behavi
