Résumé

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). Evaluations included seizure diaries, neuropsychological assessments, and scales for depression, anxiety, quality of life, and seizure severity. PuM DBS was performed using ROSA robotic assistance, with follow-ups every 3 months for 1 year. Results Out of six patients, five completed 1-year follow-up (one patient died prematurely). A non-significant trend toward seizure reduction was observed at 6 months, becoming more pronounced at 1 year (mean reduction:
