To establish efficacy of vagus nerve stimulation (VNS) therapy in the treatment of intractable epilepsy, we
compared outcome data from the baseline period to the maintenance period (7 to 24 months post-implant) by
calculating the mean seizure frequency at 6-month intervals (7 to 12 months - first study period, 13 to 18 months -
second study period, and 19 to 24 months - third study period), in 39 consecutive patients on unchanged antiepilepsy
drug (AED) regimen for 24 months following the VNS implant. Of the 39 patients24 (61.5%) at first study
period, 25 (64.1 %) at second study period and 25 (64.1 %) at third study period were responders (≥50% reduction
in seizures). Twenty one (53.9 %) patients were responders in all three study periods. Incremental seizure control
was seen in 15 of these 21 patients. Although 3 (7.7%), 4 (10.3 %).. View More»
