[Post-traumatic schizophrenia. A case]

We present a case of post-traumatic schizophrenia the interest of which lies in the plurality of aetiological factors and in the signs announcing the disease observed: many mental patients among collaterals and obsessive disorders during childhood. After a brief review of the literature, this case incites us to question the existence of such a thing as post-traumatic schizophrenia and to wonder about the role played by multifactoriality in the determinism of schizophrenia.
