Purpose: The population of elderly patients with epilepsy has been growing rapidly and the chances of referring older patients with refractory epilepsy for surgical options could be increasing. In general, epilepsy surgery at higher ages has been less likely to be performed, because little is known regarding the risks and benefits in elderly patients. We, therefore, investigated surgical outcomes and comorbidities in a population ≥ 50 years old who underwent epilepsy surgery.
Methods: Patients ≥ 50 years old who underwent epilepsy surgery were identified from the database of our epilepsy center for the period from 2009 to 2017. Surgical complications and seizure outcome were reviewed, and seizure outcomes were evaluated using the International League Against Epilepsy (ILAE) surgery outcome scale.
Results: The mean age of 32 patients at the time of surgery was 56.1± 5.1 years. The mean duration of epilepsy was 23.4± 18.5 years and mean follow-up was 2.7± 2.0 years. As of the most recent visit, 56.3% of patients remained completely seizure-free (ILAE Class I). The surgery-related complication rate was 11.5%, comprising permanent deficits in 3.8% and transient deficits in 7.7%.
Conclusion: These results suggest that epilepsy surgery may represent a valuable approach in selected adult patients.
