Sakpichaisakul K, Byars AW, Horn PS, et al. - The present study was conducted to evaluate the correlation between electrical stimulation mapping (ESM) with a visual naming task and post-operative neuropsychological outcomes after pediatric epilepsy surgery. Researchers enrolled children who had undergone epilepsy surgery, having pre- and 1-year post-surgery neuropsychological evaluation (NPE) available. The principal components (PC) analysis was applied to transform NPE scores. They examined the relationship between post-surgical PC scores, adjusted for pre-surgery PC scores, and ESM. This study recruited a total of 104 children (89 patients > 5 years-old, and 15 patients 3−5 years-old) were included. The results of this study demonstrated that speech/language ESM should be conducted more widely in patients > 5 years-of-age undergoing epilepsy surgery. For younger children, more efficient brain mapping techniques and language paradigms are required.
