Nevertheless, this review also supports that before spasm termination correlates with improved epilepsy results afterwards.[26] A retrospective Evaluation also resulted in very similar benefits; having said that, the combination procedure was in comparison to vigabatrin by vigabatrin syrup yourself.[27]
