Epilepsy Surgery Special Interest Group (SIG)

The PERC Epilepsy Surgery Interest Group is a network of U.S. pediatric epilepsy centers formed in 2018 to characterize the use of pediatric epilepsy surgery and to investigate evaluation strategies and surgical techniques. The group’s mission is to facilitate collegial, collaborative, practice-changing research that delivers answers needed to improve and define best practices for candidate selection for epilepsy surgery treatment.
