N2 - Since its conception, schizophrenia has been described in terms of distinct clinical subtypes. However, the adequacy of this categorical approach has been questioned, with a rise of the view that schizophrenic psychopathology may be best conceptualized by psychopathological dimensions. Recently, instead of viewing diagnostic categories and dimensional models as competing diagnostic systems, there has been a trend toward regarding them both as necessary to capture the phenomenological complexity of the disorder. However, the main text of Diagnostic and Statistical Manual of Mental Disorders, 5th edition, does not include this paradigm shift. Instead, the categorical subtypes of schizophrenia were removed, and the use of psychopathological dimensions is encouraged, in its appendix. The main issue with dimensional model is the lack of a single precise and agreed dimensional model. More research is required to derive this model and confirm its greater validity, which would then secure its more prominent place in diagnostic manuals and facilitate elucidating etio-pathophysiological mechanisms of schizophrenia.
