[Psychoneurologic status of preschool children who have sustained hyperbilirubinemia during the newborn period].

A study of the neurological and mental state (as well as of the functional state of some system) with the aid of EMG, REG and EEG in 110 children permitted the authors to conclude that the residual period of hyperbilirubinemia is characterized by a morphofunctional brain immaturity. Clinically it may be expressed in frequent vegetovascular disorders and different psychopathological syndromes, decreasing the adaptational possibilities of the functional systems and disturbing the social adjustment of children. The residual period of hyperbilirubinemia of the newborn is being considered as a period of a relatively favourable and unstable compensation. The authors recommend a certain system of organizational, pedagogical and medical measures ensuring mental and physical health of these children.
