[Apropos of 1 attempted suicide with a fire arm in an adolescent]

This is the presentation of an adolescent's clinical case who tried to commit suicide with a fire arm during a depressive crisis. An emphasis is placed on the family interaction model and on a more global approach of the patient's personality. The authors underlined some of the problems raised by the diagnostic approach linked to the delirious syndrome, full of psychotic elements: themes of persecution, mystico-religious themes associated with impulsive escapade, all of them going with a depressive state. They gave also an important place to a pluridisciplanary treatment in those particular stages of crisis.
