Abstrakt		Background. Hyperbilirubinemia can be related to neurological irregularities. However, the total concentration of bilirubin where irregularities typically occur more frequently has not yet been determined. Damage to the auditory nervous system includes auditory neuropathy, which results in problems related to synchronicity and processing of sound perceptions. These problems can be identified using the gap detection test (GDT). AIM. The aim of this study was to determine the degree of functional impairment of the auditory nerve in children having recovered from neonatal hyperbilirubinemia, and compare it to the degree of damage to the auditory nerve. We also compared irregularities in temporal processing of sound to irregularities in pure tone perception, and the level of functional impairment of the auditory nerve to the level of functional impairment of other nervous systems. Hypotheses. Our hypotheses were that neonatal hyperbilirubinemia affects temporal processing of sound data and translation of potentials on the nerve level; that processing of auditory information and trannslation of sound stimuli along the auditory nerve is relatively more affected than pure-tone perception following the patient's recovery from neonatal hyperbilirubinemia; and that acute neonatal hyperbilirubinemia affects the motor nervous system and cognitive functions. Methods. In the prospective study with individual retrospectively collected data, we divided the test subjects with average age of 13,5 years into two groups (n=17 in each group). An otorhinolaryngologic, paediatric and neurological clinical examinations were performed on all tests subjects, as well as Movement ABC test to assess motor functions. Data on school performance in the final school year were gathered. (Abstract truncated at 2000 characters)
