[Clinical features of the defect in children with malignant schizophrenia].

On the basis of a study of the remote period in 38 patients with early child schizophrenia who were observed during 10 years, the author describes the clinical traits of the defect. The intellectual deterioration is connected with the age of the onset and degree of development of the process. The study displayed the correlation between the clinical picture with a schizophrenic defect proper and a mental underdevelopment resembling oligophrenia ("pseudooligophrenic" defect). In 26 cases the clinical picture was characterized by symptoms of a crude schizophrenic defect, in 12 -- symptoms of mental underdevelopment. Patients of the second group displayed a better adaptation to the environment.
