Deep brain stimulation of the anterior nucleus of the thalamus (ANT) for treatment of localization-related epilepsy showed sustained efficacy and safety in this long-term follow-up of the SANTE trial. This study shows that ANT stimulation was associated with seizure frequency reduction rate of 69% at 5 years. The study also reported that 16% of subjects were seizure-free for ≥6 months during the 5 years of follow-up. ANT stimulation was associated with a 34% serious device-related adverse event rate at 5 years.
