Two recent articles in Epilepsia have raised concerns about adverse cognitive effects associated with intracranial electrode implantation. However, both studies have important limitations, and their results contrast with studies that report no adverse cognitive effects of intracranial electrodes for diagnosis or neurostimulation in epilepsy. Furthermore, no data are provided on the relative safety of depth electrodes implanted along the longitudinal axis of the hippocampus vs other electrode locations or types of electrodes. Instituting changes in the use of depth electrodes based solely on these 2 studies is not clinically indicated. Further research is needed.

Noninvasive Tests Help ID Seizure Site in Children with Focal Epilepsy
Naming tasks, which have helped to localize and lateralize a seizure onset region for surgery of focal epilepsy in adults, could now be as useful in children, with the recently reported success of a novel, age-specific assessment.
