Abstract
BACKGROUND: The aim of surgery for medically intractable epilepsy was to achieve seizure freedom and improve overall quality of life (QOL) in patients. This investigation looked at changes in QOL one year after epilepsy surgery and the relationship of changes to mood, language, and seizure outcomes. METHOD: Depressive symptoms, QOL, and naming were measured in 25 patients with temporal lobe epilepsy before and one year after dominant temporal lobe resection. The Quality of Life in Epilepsy-89 (QOLIE-89), Beck Depression Inventory II (BDI-II), and Boston Naming Test (BNT) were used, respectively, and seizure outcome was reported according to the Engel classifications. Minimum clinically important differences (MCID) and reliable change indices (RCI) were used to assess the proportion of patients who achieved meaningful improvement or worsening in the respective areas of functioning, and the relationship between outcomes was evaluated. Changes on the 17 individual items of the QOLIE-89 were also assessed. RESULTS: Overall, there was a significant improvement in QOL, reduction in depressive symptoms, and decline in naming one year after surgery. Positive clinically important improvement in QOL was achieved in 76% of patients, meaningful reduction of depressive symptoms was achieved in 20%, and clinically important naming declines were observed in 48% of the cohort. Sixteen patients were seizure-free one year after surgery, but there was no significant correlation between changes in QOL and seizure outcome, depressive symptoms, or naming. CONCLUSION: The results in the reported cohort of patients showed that surgical treatment of temporal lobe epilepsy in the dominant hemisphere resulted in clinically meaningful improvement in overall QOL and declines in naming but no significant reduction of mood disturbance.
