Abstract

Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures, affecting millions worldwide. While anti-seizure medications serve as first-line treatment, approximately one-third of patients develop drug-resistant epilepsy (DRE), necessitating alternative interventions. Deep brain stimulation (DBS) has emerged as a promising therapy for DRE, particularly for patients who are ineligible for resective surgery. DBS involves stereotactic implantation of electrodes into target brain regions, such as the anterior nucleus of the thalamus (ANT), centromedian nucleus (CMT), and hippocampus (HC), to modulate aberrant neural activity and to reduce seizure frequency. Anesthesia plays a critical role in DBS implantation, influencing both patient safety and procedural success. The choice of anesthetic technique must balance patient comfort with the preservation of neurophysiological signals used for intraoperative electrode localization. A well-chosen anesthetic strategy can enhance the efficacy of electrode placement by minimizing patient movement and preserving critical neurophysiological signals for real-time monitoring. This precise targeting enhances safety via a reduction in perioperative risks and an improvement in long-term seizure control. Anesthetic considerations in epilepsy patients differ from those in movement disorders due to variations in their nuclei targets during DBS. Despite the increasing use of DBS for epilepsy following its FDA approval in 2018, research on anesthetic effects specific to this population remains limited. This narrative review, therefore, examines anesthetic approaches, pharmacological implications, potential complications, and evolving methods for DBS implantation in epilepsy patients, highlighting new insights and unique considerations in this population. Understanding these factors is essential for optimizing surgical outcomes and improving the safety and efficacy of DBS in epilepsy treatment.
