[Terminology problems in schizophrenia]

The author submits a new classification of schizophrenias, schizotype, hallucinatory and other disorders as found in the 10th revision of the International Classification of Diseases (ICD 10) in the chapter bearing the code F20-F29. Some new units will be found (post-schizophrenic depressions, schizotype disorders); paraphrenia and paranoia are no longer separate units. The new revision will be valid from Jan. 1, 1993; by a five-digit classification it will make as regards symptoms and course of mental disorders a more accurate diagnosis possible.
