Vertigo and dizziness are common neurological complaints that have long been associated with epilepsy. However, studies of patients with epileptic vertigo or dizziness with concurrent EEG monitoring are scarce. We performed the present study to investigate the incidence and localizing value of vertigo and dizziness in patients with epilepsy who had confirmation of EEG changes via video-EEG monitoring. Data of aura and clinical seizure episodes of 831 consecutive patients who underwent video-EEG monitoring were analyzed retrospectively. Out of 831 patients, 40 patients (4.8%) experienced vertigo or dizziness as aura (mean age, 32.8±11.8years), all of whom had partial seizures. Eight had mesial temporal, 20 had lateral temporal, four had frontal, one had parietal, and seven had occipital lobe onset seizures. An intracranial EEG with cortical stimulation study was performed in seven patients, and the area of stimulation-induced vertigo or dizziness coincided with the ictal onset area in only one patient. Our study showed that vertigo or dizziness is a common aura in patients with epilepsy, and that the temporal lobe is the most frequent ictal onset area in these patients. However, it can be suggested that the symptomatogenic area in patients with epileptic vertigo and dizziness may not coincide with the ictal onset area.
眩晕和头晕是常见的神经科症状，长期以来一直与癫痫相关。然而，对癫痫性眩晕或头晕患者同时进行脑电图监测的研究很少。我们开展本研究，以调查经视频脑电图监测证实有脑电图变化的癫痫患者中眩晕和头晕的发生率及定位价值。回顾性分析了831例连续接受视频脑电图监测患者的先兆和临床发作事件数据。在831例患者中，40例（4.8%）经历过眩晕或头晕为先兆（平均年龄32.8±11.8岁），所有这些患者均为部分性发作。8例为颞叶内侧发作，20例为颞叶外侧发作，4例为额叶发作，1例为顶叶发作，7例为枕叶发作。对7例患者进行了皮质刺激的颅内脑电图研究，仅1例患者刺激诱发眩晕或头晕的区域与发作起始区域一致。我们的研究表明，眩晕或头晕是癫痫患者常见的先兆，且颞叶是这些患者最常见的发作起始区域。然而，可以认为癫痫性眩晕和头晕患者的症状产生区域可能与发作起始区域不一致。
