To the Editor: The efficacy of epilepsy surgery (73% seizure-free) in the best-possible surgical candidates was corroborated by Dr Engel and colleagues.1 Their trial also showed that surgery can cause irreversible deficits because a statistically reliable decline in performance on memory tests was more frequent in the surgical group (36% in delayed recall and 55% in naming) than in the medical group (0% and 7%, respectively).1 Other aspects of the trial might deserve some clarification.
