This article is about specificity of schizophrenia care with the evolution of these last years and the help of Cognitive Remediation to improve the quality of life and the insertion of these patients. First, we describe the criteria of international classifications (DSM V and ICD 10) and the fact that they are not completely the same. To illustrate this limit, we define the frequent case of brief psychosis, it can be an isolate episode in a life or not. Sometimes, the evolution is the chronic illness. Then, the cognitive approach is a new definition of psychotic disorders. The question is how to help these patients to adapt their cognition with the society and how to help them to compensate their deficits. Here, are described more precisely IPT, CRT, RECOS, REHACOM® and RC2S programs with the necessity of a personal accompaniment. Explain them the trouble is essential and depend of the singularity of each subject in his own culture and family history. Randomized studies show that Cognitive Remediation, new medications and psychotherapies are supplementary to cure schizophrenia and psychosis as an illness like any other.
