[A case of Bleuler's disease? 100 years of dementia praecox or group of schizophrenias].
Approximately 100 years ago Eugen Bleuler published the most significant contribution to psychiatry by conceptualizing the term schizophrenia as a diagnostic entity. In modern diagnostic manuals Bleuler's concept is only reflected in subordinated criteria, i.e. the negative symptoms. On the occasion of the anniversary of Bleuler's essential publication, the present work aims to exemplify the differences in diagnostic concepts and it will be illustrated that Bleuler's intention to establish his so-called basic symptom as a guideline for diagnostics has to be considered as failed from a present day viewpoint.
