Analysis of Power Spectrum and Phase Lag Index Changes following Deep Brain Stimulation of the Anterior Nucleus of the Thalamus in Patients with Drug-Resistant Epilepsy: A Retrospective Study

Objectives: The mechanisms underlying the anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS) for the treatment of drug-resistant epilepsy (DRE) have not been fully explored. The present study aimed to measure the changes in whole-brain activity generated by ANT DBS using interictal electroencephalography (EEG).Materials and Methods: Interictal EEG signals were retrospectively collected in 20 DRE patients who underwent ANT DBS surgery. Patients were classified as responders or non-responders depending on their response to ANT DBS treatment.
