Effects of epilepsy surgery on quality of life: a controlled study in a Middle Eastern population

The purpose of this study was to investigate which areas of quality of life (QOL) change after epilepsy surgery and generate QOL data specific to the Lebanese population. The QOL of 20 consecutive patients 1 year after surgery was compared (using the ESI-55 scale) with that of 20 matched patients who underwent the same presurgical evaluation, but no surgery. Overall QOL improved in both groups, but was greater in the surgery group (85% seizure free as compared to 0% in nonsurgery group). Significant differences were noted within the "well-being" domain including health perception (5/9 items), energy-fatigue (2/4), and emotional well-being (2/5). Differences were less common in the "functioning" domain including physical (1/10 items), social (1/2), and cognitive (0/5) functioning scales, and in the role limitation domain (1/17 items). Our patients experienced, 1 year after epilepsy surgery, improvements similar to those reported in Western populations after a similar period: they had marked improvements in overall QOL, health perception, well-being, and cognitive functioning areas. They had less remarkable improvements in social functioning and role limitation areas.
