Abstract

Distinctions and dichotomies within the groups of schizophrenic disorders are as old as the concept of schizophrenia itself. Some of the distinctions were made according to the phenomenology, like the classical distinction of paranoid- hallucinatory, hebephrenic, catatonic, and simplex forms. Other distinctions are based on the prognosis (benign/non-benign, process/non-process, deficit/non-deficit, good prognosis/poor prognosis, etc.). Others are based on an assumed etiology, such as reactive (psychogenic)/process schizophrenia, or organic/endogenous schizophrenia (Marneros and Tsuang, 1991).
