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.

Despite expectations that circadian and sleep disruption related to daylight savings time transitions would increase the incidence of seizures, this study found little substantive evidence for such an association in this large, longitudinal cohort.
