AIM: The analysis of the data from the psychiatric hospitals in Lubliniec (1894-1932, 1934-1936, 1970-1999) and Boleslawiec (1958-1999) proved a decrease in frequency of diagnosis of catatonic schizophrenia, what could testify to a decrease in morbidity with this form of schizophrenia. METHOD AND RESULTS: Basing on the facts from scientific literature there was ascertained that the decrease in frequency of diagnosis of catatonic schizophrenia is connected with following causes: firstly, with the changes in nozology, secondly, with the introduction of a new form of therapy and finally, with the fact that here psychological and sociological factors exist which eliminate catatonia as the most expressive form of schizophrenia.
