Abstract:
Patients afflicted with low-grade glioma frequently suffer from seizures. The mechanisms for seizure initiation in these patients remain poorly understood. Tumor location is correlated with seizure initiation. However, these correlative studies rely on dichotomized data analysis which is based on arbitrary lobe assignments. As a result, the lesion-symptom correlation may be incorrectly interpreted. Categorizing patients according to tumor involvement in a single brain lobe might cause the neglect of important information, such as lesion location and lesion volume. Tumors that invaded more than one brain lobe may could be counted repeatedly. The anatomic correlation of the tumor-induced seizures is therefore difficult to be identified. Investigations based on voxel-wise quantitative lesion analysis could avoid the above statistical bias. According to the voxel-wise analysis, the increased seizure risks were identified for patients with low-grade gliomas that involved the left premotor area.
