Dimensional and Developmental Profiles of Psychosis in Children and Adolescents

France200 participantsStarted 2021-06-02

Plain-language summary

Five collaborating sites in France will study the broad spectrum of schizophrenia in children and adolescents. Patients will be studied with diagnostic interviews, developmental histories, dimensional clinical ratings, comprehensive cognitive assessments, neuroimaging and DNA (copy number variant) analyses (in families and patients who agree), and follow-up of course of illness, cognitive status and treatment response to specific antipsychotic drugs. The goal of the study is to test a prior hypothesis about clinical subgroups in this population and to test whether these subgroups predict antipsychotic medication response.
