 Objective: The impact of intrauterine growth restriction IUGR on perinatal morbidity and long-term neurodevelopmental outcome has been published in numerous studies. Throughout this analysis, the influence of IUGR on the postnatal amplitude-integrated EEG aEEG in preterm infants below 30 weeks of gestation was assessed. The second concern was the correlation between the pattern of the aEEG in the first two weeks with neurodevelopmental outcome, comparing infants with and without IUGR.
