Psychoses délirantes aiguës

According to the French school of psychiatrics, the term “acute delusional psychosis” refers to a clinical syndrome characterized by an acute onset, the intensity and the polymorphism of the delirium, and a favorable course. Classically, this entity is not restricted to schizophrenia and manic-depressive psychosis. The authors examine the current relevance of this question, especially with regard to current theories on schizophrenia. The acute psychotic episode reflects both fragility and plasticity. Its evolution depends on management and treatment, in an open dialectic among the subject and his specific history, his environment and the interaction modalities proposed in the therapeutic context and that makes the prediction relative. Acute delusional psychosis must retain its identity, at least from a heuristic point of view.
