[Terminal states of schizophrenia in old age].

On the basis of a study of 217 patients with terminal schizophrenic states in old age the author found it possible to distinguish 2 forms of such conditions: psychotic and deficient. The psychotic forms were expressed in syndromological polymorphic psychoses, which most frequently reflected the form of the process development and which is senescence often enough undergone pathoplastical changes. The deficiency forms were presented by apathic dementia, while the connection with the previous form of development was lost. In many cases in old age there was worsening of the states with a senile-like change of the clinical picture.
