The Circle of Excellence on Psychosis (CEP) is a structure which aims at sharing knowledge relevant to the field of psychosis. It targets the whole European community, in order to increase interactions as much as possible. It is open to all participants, clinicians, psychologists, neuropsychologists, researchers, nurses, etc..., experts or not, who face this pathology. Its approach is medical: the CEP uses the WKL system of classification, yet favours a polydiagnostic strategy and has developed personalized TMS treatment, leading to the creation of CEMNIS. The CEP organizes trainings, seminars & symposia. Moreover, it provides e-teaching available from the CEP website and from the Neurex multimedia platform.
