Abstract: | We analysed the association of presurgical language fMRI activations and postsurgical verbal memory changes in 16 left-sided mesial temporal lobe epilepsy patients with initially intact memory. Patients with severe verbal memory decline after surgery (n = 9) had stronger presurgical fMRI activations within the left posterior temporal lobe, compared to those with no decline (n = 7). Language fMRI activation may predict verbal memory outcome, even in patients with a high risk of postsurgical memory deterioration. |
