The Evolution of Approaches to Schizophrenia Diagnostics: from Kraepelin to ICD-11

Abstract

This article presents the evolution of views on schizophrenia diagnostics over the course of 150 years, beginning from the pre-Kraepelin period and ending with concepts developed in recent decades. Consideration is given to the merits and demerits of contemporary official classifications (DSM-5 and ICD-11) as well as to alternative approaches, particularly in relation to scientific research, and their prospects for development. Special attention is paid to the Research Domain Criteria Project (RDoC) of the National Institute of Mental Health (NIMH). Another promising area discussed in this paper relates to network analysis as a method for the investigation of psychotic disorders, particularly schizophrenia.
