Right-sided vagus nerve stimulation: Worldwide collection and perspectives.

Objective: Vagus nerve stimulation (VNS) is an established therapy for drug-resistant epilepsy (DRE) and is indicated for implantation on the left vagus nerve-only. In rare cases right-sided VNS may be the only option. With only seven published cases in the literature, data on safety and effectiveness of right-sided VNS is very limited.

Stereoelectroencephalographic exploration and surgical outcome in Lennox-Gastaut syndrome.

Objective: Lennox-Gastaut syndrome (LGS) is typically characterized by drug-resistant epilepsy and subsequent cognitive deterioration. Surgery is a rare but viable option for the control of seizures in a subset of patients with LGS. This study aimed to describe the organization of the epileptogenic zone network (EZN) in patients with LGS using stereoelectroencephalography (SEEG) and to report the outcome of post-SEEG treatment.

Vagus nerve stimulation lead durability: Insights from an extensive monocentric single-operator adult series.

Background: Vagus nerve stimulation (VNS) is an established surgical option for neuromodulation. Lead failure is a significant complication mainly reported in children.

Methods: We conducted a retrospective review of all VNS-related surgeries for refractory epilepsy in adults performed by a single experienced surgeon at a French national referral center from November 2011 to March 2023.

Medial pulvinar stimulation for focal drug-resistant epilepsy: interim 12-month results of the PULSE study.

Objective: This study aims to evaluate the efficacy and safety of deep brain stimulation (DBS) of the medial pulvinar nucleus (PuM) in reducing seizure frequency and addressing comorbidities in patients with drug and vagal nerve-resistant focal epilepsy.

Methods: This is an open-label prospective treatment trial with a planned enrollment of 12 patients suffering from medically refractory epilepsy (Clinical trial gov NCT04692701), for which the interim 12-month post-implantation results for the first 6 patients are being reported. Inclusion criteria were focal epilepsy not suitable for or after failed surgical intervention and previous failure of neurostimulation therapies (vagus nerve stimulation or anterior thalamic nucleus DBS).

Non-invasive Temporal Interference Stimulation of the Hippocampus Suppresses Epileptic Biomarkers in Patients with Epilepsy: Biophysical Differences between Kilohertz and Amplitude Modulated Stimulation.

Medication refractory focal epilepsy creates a significant challenge, with approximately 30% of patients ineligible for surgery due to the involvement of eloquent cortex in the epileptogenic network. For such patients with limited surgical options, electrical neuromodulation represents a promising alternative therapy. In this study, we investigate the potential of non-invasive temporal interference (TI) electrical stimulation to reduce epileptic biomarkers in patients with epilepsy by comparing intracerebral recordings obtained before, during, and after TI stimulation, to recordings during low and high kHz frequency (HF) sham stimulation.
