[Several developmental disorders in children with schizophrenia].

The authors discusses some unclear and insufficiently studied problems related to early infantile autism, regress of development and underdevelopment of schizophrenic children. The basis of early infantile autism is most likely a peculiar disturbance of development due to constitutional, organic and psychogenic factors. In most of the cases this syndrome is connected with the schizophrenic process. The majority of psychiatrists in the Soviet Union consider lowering to a more early level of development as a regress of development in child schizophrenia symptoms. The clinical picture of retarded development in childhood schizophrenia depends upon the age of the onset of the disease and the degree of progressiveness of the process. Depending upon these criteria it is possible to distinguish retarded development, resembling oligophrenia and phenomena of psychophysical infantilism.
