title: [Clinical systematics of retarded mental development].
abstract: The clinical classification of mental retardation is reported. Three main clinical groups were screened: 1) mental retardation, due to the immaturity of the emotional-volitional sphere (different forms of mental infantilism); 2) mental retardation due to disturbances in the cognitive sphere (in stable neurodynamical and encephalopathic disturbances, deficiency in the higher cortical and subcortical functions; in disturbed regulation of cognitive activity); 3) general mental retardation, due to a combination of a disturbed cognitive sphere with organic infantilism. The paper concerns differential criteria for oligophrenia. It is recommended that children with stable retardation of the cognitive sphere be taught in special schools.
