Official title
Early Identification of Patients Presenting a First Psychotic Episode, Non Answering to First Line Support Strategies: A Multicentric Study
Overview
Researchers propose in this project to evaluate predictive factors of non response. It is defined by the lack of symptomatic remission at month 3, for patients presenting a first episode of psychosis. It will be performed on objective markers taken from imagery techniques. The link between evolution of these markers and clinical measures will be studied.
Detailed description
Recently, radiological markers demonstrated a good capacity to discriminate first episode of psychosis patients, that will show a bad response to treatment. Furthermore, automatic learning methods were recently successfully applied to neurological data, but never for the first episode psychosis patients. These powerful methods are based on multivariate analyses allowing the prediction at an individual stage. The possibility to identify more precisely the population of non-answering patients would allow the adaptation of the support in first attention for these patients, and consequently to perform appropriate cares.

Interventions
- Procedure MRI
Magnetic Resonance Imagery will be performed on patients attempted by schizophrenia. The aim of this intervention is an early detection of the non-answering patients to the primary cares.
Primary outcome measures
- Score of the predictive value of the imagery markers. [Time frame: Month 3]
