Simple schizophrenia: past, present, and future
DW Black and TJ Boffeli
Department of Psychiatry, University of Iowa College of Medicine, Iowa City.
The diagnostic category called simple schizophrenia has disappeared from
official American nosology but has been retained in ICD-9. The diagnosis
has a long history, was one of the traditional schizophrenic subtypes
identified by Bleuler, and was later accepted by Kraepelin. The authors
provide a historical overview of the concept, review its modern successors,
and provide recommendations for its inclusion in DSM- IV as a proposed
diagnostic category needing further study.
