| Abstract: | Creatinphosphokinase (CPK) was determined in 141 patients with manic-depressive and schizophrenic psychoses. In general endogenic psychoses of the manic and depressive type as well as chronic schizophrenias show normal CPK values. In acute cases of paranoid-halluzinatory schizophrenias normal values are predominant. In catatonic schizophrenias, as a rule, clearly increased enzyme activities are found. Thise increased values suggest a postulated somatic disease as a cause of the psychosis. Thus, the determination of CPK provides a useful aid in the diagnosis and control of the course of catatonic schizophrenic. |
