Update of diagnostic criteria and classification changes of schizophrenia

Abstract:

Schizophrenia is a group of severe mental disorders with unknown etiology. Since there are no biological markers to diagnose so far, the diagnosis of schizophrenia is mainly based on symptomatology. This article describes the diagnostic criteria and classification changes of schizophrenia in International Statistical Classification of Disease and Health Problem (ICD) and Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnostic systems, in order to increase the understanding of the content of each diagnostic system by clinicians.
