Early Identification of Patients Presenting a First Psychotic Episode, Non Answering to First Line Support Strategies

Recruiting now

Conditions studied: Schizophrenia

In brief

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.
