This systematic review and meta-analysis evaluates the effectiveness and safety of responsive neurostimulation (RNS) in children with drug-resistant epilepsy. By analyzing 39 studies involving over 400 patients, the researchers found that approximately two-thirds of pediatric patients experienced a reduction in seizure frequency of at least 50%. While total seizure freedom remains rare at roughly 3%, this outcome improved significantly with longer follow-up durations, suggesting that the brain benefits from cumulative stimulation over time. The study also highlights that non-seizure outcomes…
