Neuropsychological correlates of electroencephalograms in children with epilepsy

Children with slow-wave activity on EEG might be at increased risk for developing neuropsychological deficits. When these abnormalities are observed on a child's EEG, closer monitoring of cognitive and academic functioning seems warranted. Differences between these findings and past research suggest that conclusions drawn from adult surgical studies cannot be generalized to pediatric patients, especially recent-onset samples, without qualification. Differences between the recent-onset and chronic samples in this cross-sectional study raise the possibility that neurophysiological abnormalities have a cumulative effect on cognitive development.
