title: Paranoid schizophrenia: an unorthodox view.
abstract: Most paranoid patients have traditionally been diagnosed as schizophrenic, although considerable evidence points to the dissimilarities between paranoid and nonparanoid schizophrenic patients and to commonalities between paranoid and affective disorder groups. Based on a review of research, it is suggested that paranoid schizophrenia, at least in some of its varieties, may more fruitfully be conceptualized as a phenotypic expression of an underlying depressive mode than as a schizophrenic form. This formulation is presented within the framework of a broad examination of diagnostic issues.
