Article Title：Brainstem auditory-evoked potentials of 8-year-old preterm children in relation to their psycholinguistic abilities and MRI findings
Abstract：
Background: Brainstem auditory potential (BAEP) has been used to demonstrate brainstem damage and to provide prognosis for the outcome for newborn children. There are contradictory results of its power to predict problems in language development or problems at school. It is well known that preterm children experience an excess of these problems. Aim: To study if BAEP findings of 8-year-old preterm children differ from those of the full-term born control children and whether there is correlation to their linguistic problems or to the findings in magnetic resonance imaging (MRI). Study design: Population-based cohort study. Subjects: Forty-two preterm children aged 8 years born with birth weight < 1750 g and their matched full-term control children with birth weight >2500 g, 24 of whom had BAEP recordings and MRI. Outcome measures: Differences in BAEPs between the preterm and the control children. Correlation of BAEPs with linguistic problems and with MRI findings. Results: No differences were found in the absolute latencies nor in the interpeak intervals and in the I/V amplitude ratio. Nor did the results differ even when cerebral palsy disabled preterm children, preterm children with mild neuro-developmental dysfunction or healthy preterm children were compared to each other or to the control children. No correlation to the linguistic problems or to the findings of periventricular leukomalacia (PVL) in MRI or to the different measurements of the brainstem were found. Conclusion: If hearing impairment does not exist, BAEP does not give further information on neurodevelopmental nor linguistic problems, of the preterm children. (C) 2002 Elsevier Science Ireland Ltd.
