| 8. | Language related brain region～From an epileptologist’s point of view Study of the localization of brain language areas started with findings obtained from patients with brain injury, however functional localization studies in epileptology began with findings on brain functional mapping using cortical electrical stimulation during brain surgery. Knowledge of language area identification and knowledge of language sequelae due to brain resection is essential for those engaged in epilepsy surgery. In recent years, many non-invasive examination and analysis methods have been developed, and it has become possible to carry out measurements on not only pathological brains such as epilepsy and cerebrovascular disease but also normal brains. In this educational lecture, I will introduce the language areas related to epilepsy treatment and actual brain functional mapping. In addition, recent findings on the language areas that are becoming clear by use of various examinations and analysis methods will be discussed, that is, the language areas related to vision, the language areas related to hearing, and the white matter tracts that connect cortical language areas. These language areas will be discussed together with some cases.. |

Methods: We retrospectively investigated surgical outcomes in patients with neocortical or medial temporal lobe epilepsy who underwent temporal lobe resection between May 2014 and June 2017, and were observed for a minimum of one and half year after the surgery. To identify independent predictors for seizure relapse, we first used the univariate analysis (gender, seizure-onset age, using preoperative AEDs treatment, surgical side, pathology, etc.) to find significance differences and then used Cox’s proportional hazards analyses for multivariate analysis using results of univariate analyses. Results: A total of 41 consecutive patients were included in this study. Estimated epileptogenic zone in neocortex, existence of inter-ictal epileptiform discharges after operation, and duration of disease before surgery were significantly associated with seizure relapse, whereas preoperative treatment of new AEDs did not change the outcome: (1) Neocortical temporal lobe epilepsy compared to medial temporal lobe epilepsy (hazard ratio [HR] 0.363, 95% confidence interval [CI] 0.162-0.809; p=0.013), (2) Postoperative inter-ictal epileptiform discharges on EEG (HR 0.475, 95% CI 0.240-0.939, p=0.032), (3) Shorter duration of disease (HR 0.965, 95% CI 0.942-0.990, p=0.005). Conclusions: Our study disclosed that the patients with estimated epileptogenic zone in neocortex, postoperative inter-ictal epileptiform discharges, and shorter duration of disease before surgery are more likely to experience seizure recurrence postoperatively. Our results may be useful for selecting candidates for resective surgery in patients with temporal lobe epilepsy.. |
