On the basis of a study of 51 patients with schizophrenia older than 60 years of age with catatonic outcome states the author accomplished differentiation of these conditiones with consideration of the character of the catatonic symptoms, as well as of the whole structure of the state. It was demonstrated that in the elderly the most diverse of the described in literature catatonic outcome states may be encountered. A significant percentage of the studied cases was with outcome states, prevalence of speech disorders and certain restoration of adaptation.
