AIm: The aim of this study was to find out if vagal nerve stimulation (VNS) affect the generalized-partial seizure count and medical treatment in adult drug resistant epilepsy patients. Mater Ial and Methods: Twenty adult patients who were diagnosed with drug-resistant epilepsy were investigated retrospectively for vagal nerve stimulator implantation between 2001 and 2010 at the Neurosurgery Departments of Ufuk University and Gulhane Military Medical Academy. The effects of vagal nerve stimulation on generalized-partial seizures and medical treatment was scored and if a significant difference was found, a comparison was made by Wilcoxon Signed Ranks test and Pairwise. For all the group analyses, the statistical significant rank was accepted as a p value <0.05. Bonferroni correction was made when it was needed during pairwise comparisons. Results : VNS significantly decreased the scores of generalized-partial seizures. There was no decrease in the doses of antiepileptic drugs and the medical treatment was resumed as before the implantation. The results were correlated with the relevant literature. ConclusIon: VNS is an alternative treatment option for drug resistant epilepsy for patients who are not ideal candidates for surgery or are not healed after epilepsy surgery.
