[Preventing dangerous psychotic acting out].

Delusions of having been wronged, of persecution, of having a mission or order to execute, are frequently the causes of dangerous psychotic acting out. The regular clinical assessment of these patients and their treatment is essential for preventing this acting out, which can have dramatic consequences on the potential victims. If there is a treatment indication but refusal on the part of the patient to cooperate, it is necessary to resort to treatment without the patient's consent.
