Vella, S. Cynthia. & Pai, N. B. (2015). Negative symptoms of schizophrenia: a historical, contemporary, and futuristic view. Archives of Medicine and Health Sciences, 3 (2), 329-334.


This paper explores the evolution of the conceptualization of schizophrenia. Specifically, the paper focuses upon negative symptomology and the emphasis that such symptoms have garnered over time. Negative symptoms are associated with higher levels of impairment and poorer outcomes in schizophrenia. Historically, negative symptoms were the core feature of schizophrenia in the early conceptualizations of Kraepelin and Bleuler, holding precedence until the emergence of Schneiderian theory in the 1970's. The focus on negative symptoms then changed to positive symptoms; which is still the key focus today. This shift in emphasis has resulted in a dearth of knowledge and treatment for such symptoms and as such an area requiring further research. The paper also addresses the conceptual changes in the nosology of Schizophrenia and other psychosis with respect to the Diagnostic and Statistical Manual of Mental Disorders-5. Further the potential for the clinical assessment interview for negative symptoms to facilitate understanding and treatments for negative symptomology in schizophrenia is also discussed.
