The semiology of epileptic seizures reflects activation, or dysfunction, of areas of brain (often termed the symptomatogenic zone) as a seizure begins and evolves. Specific semiologies in focal epilepsies provide an insight into the location of the seizure onset zone, which is particularly important for presurgical epilepsy assessment. The correct diagnosis of paroxysmal events also depends on the clinician being familiar with the spectrum of semiologies. Here, we summarise the current literature on localisation in focal epilepsies using illustrative cases and discussing possible pitfalls in localisation.

局灶性癫痫的定位：实用指南

癫痫发作的符号学反映了癫痫发作开始和发展时大脑区域（通常称为症状区）的激活或功能障碍。局灶性癫痫的特定符号学提供了对癫痫发作区位置的洞察，这对于术前癫痫评估尤为重要。对阵发性事件的正确诊断还取决于临床医生是否熟悉符号学的范围。在这里，我们使用说明性案例总结了当前关于局灶性癫痫定位的文献，并讨论了定位中可能存在的缺陷。
