Literature Review

Treatment of Atonic Seizures: Corpus Callosotomy or Vagus Nerve Stimulation?

A systematic review of the literature



A literature review showed that patients with atonic seizures and/or drop attacks who underwent corpus callosotomy (CC) were significantly more likely to achieve a greater than 50% reduction in seizure frequency compared with those who underwent vagus nerve stimulation (VNS). Adverse events were more common with VNS but they were typically mild. The most common complication of CC was disconnection syndrome. A direct study comparing both techniques is needed.
