Temporal lobe epilepsy surgery provides potential seizure relief but carries a risk of cognitive decline, particularly in naming functions for left-sided resections. A study of 153 patients revealed that 42% of those with left temporal lobe epilepsy experienced significant naming decline post-surgery, though some recovered after two years. Factors influencing recovery included age at seizure onset and verbal memory performance. The degree of early decline was a robust predictor of long-term outcomes, emphasizing the need for preoperative counseling regarding cognitive risks.
