title: [Psychotic parricide. Prevention].
abstract: RESULTS
  Parricide is a rare event. In France, statistics indicate that it accounts for 2 to 3% of all homicides. It also represents an appreciable part (up to 30%) of homicides committed by psychotic subjects. Many studies suggest a strong positive correlation between criminality and characterized mental illness. The correlation is better when there is a diagnosis of schizophrenia, an alcohol or drugs consumption and a past personal history of violence. Parricide is a crime mainly committed by males. The most frequent form of parricide is patricide committed by sons. However, considering only psychotic parricides, the number of mothers killed seems is equal or higher to the number of fathers killed.
  
  
  METHODS
  The typical profile of an adult committing parricide could be described as follows: a young single unemployed male, living with his victim, suffering from schizophrenia with comorbidity of alcohol or drug abuse and consumption, who stops his medication, and having a past history of medicolegal behaviours. The parricide act can be divided into three stages; first, the contention of the emergence of parricide ideas; second, the violence and brutality of the act; third, following a transient appeasement suicidal thoughts or attempts are frequently observed.
  
  
  CONCLUSIONS
  Preventing parricides and homicides committed by psychotic subjects is a great challenge. Only a few studies aim to a better understanding of the underlying motivations of such criminals. According to theses studies, we can point out several warning signals. Psychiatrist should particularly increase their vigilance to persecutive delusions, history of a long lasting illness with history of violence during acute stages, threats against family or friends, suicidal thoughts, failures of help requests and attempt to escape.
