About this trial
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.
