La « folie à deux » dans l'œuvre de Clérambault

In this text, the author presents G. Gatian de Clérambault's interventions concerning « folie à deux ». These are viewed from a historical perspective from a draft of a nosography of mental diseases. The evolution of his different contributions shows de Clérambault's concern with the concept of mental automatism in his nosography, which, as it is based on the clinical identification of a supposed psychoses-generating mechanism, is similar to a structural approach. To that extent, de Clérambault's work brought a new vision to psychotic disorders in small groups and deserves recognition.
