Paranoid Schizophrenia Coined by Eugen Bleuler in 1950, the term "schizophrenia" refers to a group of mental disorders with heterogeneous outcomes. The most common subtype of schizophrenia is the paranoid subtype. Typically, this disorder is characterized by psychosis, in which the patient suffers from altered perceptions of reality. According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM – V), the typical subtypes – paranoid, catatonic and disorganized, among others, have been eliminated, although the general definition of the disorder remains unchanged. These changes have been made due to the clinically different prognosis, pathophysiology, and etiology of the disorder, which add to its heterogeneity1, 2. Furthermore, the patient's sex and age of onset of the disorder also contribute to the different effects of schizophrenia.
