Vagus nerve stimulation for intractable epilepsy: outcomes in children and adults.

Objectives. Vagus nerve stimulation (VNS) is an accepted treatment for medically intractable epilepsy. However, predictive factors associated with responsiveness to VNS remained unclear.

Effect of a ketogenic diet on EEG: analysis of sample entropy.

Although ketogenic diet (KD) is an effective alternative therapy for controlling intractable seizures, the anticonvulsant mechanism still remains unclear. Sample entropy (SampEn) provides a generalized measure of regularity in time-series data. To investigate the potential anticonvulsive mechanism of a KD, we analyzed the SampEn of electroencephalography (EEG) data in patients with intractable pediatric epilepsy before and after treatment with a KD.
