[Homicide and major mental disorder: what are the social, clinical, and forensic differences between murderers with a major mental disorder and murderers without any mental disorder?].

Objectives: To establish the social, clinical, and forensic differences between murderers suffering from a major mental disorder and murderers without any psychiatric disorder and, in particular, to compare their respective records of psychiatric symptoms and their respective relationship with their victims.

Method: We studied 210 forensic examinations of murderers, the offences related to the murders, and the social and clinical information collected from psychiatric court reports on persons convicted of homicide. Firstly, we identified the socio-demographic, clinical and criminological profiles of 210 murderers from which were distinguished murderers with major mental disorder.
