brain ultrasonography findings in neonatal seizure; a cross-sectional study

introduction: screening of newborns with seizure, who have curable pathologic brain findings, might be able to improve their final outcome by accelerating treatment intervention. the present study aimed to evaluate the brain ultrasonography findings of newborns hospitalized with complaint of seizure. methods: the present cross-sectional study designed to evaluate brain ultrasonography findings of hospitalized newborns complaining seizure.  neonatal seizure was defined as presence of tonic, clonic, myoclonic, and subtle attacks in 1 - 28 day old newborns. results: 100 newborns with the mean age of 5.82 ± 6.29 days were evaluated (58% male). most newborns were in the < 10 days age range (76%), term (83%) and with normal birth weight (81%). 22 (22%) of the ultrasonography examinations showed a pathologic finding. a correlation was only found between birth age and probability of the presence of a pathologic problem in the brain as the frequency of these problems was significantly higher in pre-term newborns (p = 0.023). conclusion: based on the findings of the present study, frequency of pathologic findings in neonatal brain ultrasonography was 22%. hemorrhage (12%) and hydrocephaly (7%) were the most common findings. the only factor correlating with increased probability of positive findings was the newborns being pre-term.
