Overview: the heuristic need for subgroups of the schizophrenic syndrome
Abstract:
This article is an editor's introduction to the theme of an issue of the Schizophrenia Bulletin devoted to subgroups of the schizophrenic syndrome. The issue includes articles on subtyping from various points of view: neurological, genetic, biochemical, and descriptive. It is hoped that the wide range of findings being applied in ongoing classificatory efforts will produce subgroups with etiologic, prognostic, and treatment validity.
