Breaking the age barrier: Epilepsy surgery in septuagenarians.

Resective epilepsy surgery (RES) has traditionally been offered to young patients (<50years). The reservation about offering RES to the elderly is multifactorial with their advanced age and comorbidities being the primary reason. The elderly age group (≥65years of age) is one of the fastest growing populations. The arbitrary age limits for RES need reconsideration in the face of an ever increasing elderly population. Considering such changes in demographics, we report the first case series in the literature of seven septuagenarians who underwent RES in the form of anterior temporal lobectomy (ATL). The 10-year median survival probability based on their comorbidities and age was more than 50%. Six patients had good surgical outcome (Engle I/II) with four of them being completely free of disabling seizures after a median follow-up of almost 2years. No significant medical or surgical morbidity was observed. However, three out of the four patients undergoing pre- and post-RES neuropsychological testing showed decline in memory function. Seizure-related injuries were noted in four out of seven patients and may have been a motivation to proceed with RES in our cohort. Our experience suggests that RES can be a safe and effective therapy in well-selected, septuagenarian patients with drug-resistant epilepsy. Neuropsychological outcomes after RES in this population need further evaluation.
