摘要
目的分析以眩晕为先兆或主要表现的癫痫患者的临床特征、脑电图、神经影像学、治疗效果及预后。方法回顾性研究70例以眩晕为先兆或主要表现的癫痫患者,详细询问病史及神经系统查体,分析发作期及发作间期脑电图、影像学检查资料,评价治疗效果及预后。结果以眩晕为先兆或主要症状的癫痫患者占所有癫痫患者的3%。眩晕发作具有突发突止,常伴意识改变、肢体抽搐、头眼偏转等提示癫痫发作的症状,发作时很少有眼震,发作与体位变化无关,脑电图及颅脑影像学检查阳性率较高等特点。病变主要位于额、颞、顶区。结论以眩晕为先兆或主要表现的癫痫可以通过临床表现及脑电图与其它原因引起的眩晕相鉴别。眩晕的大脑皮层定位主要位于额、颞、顶区。
Objective To make a comprehensive understanding of epilepsy with vertigo as their aura or main presentation, the clinical, electroencephalogram （EEG）, neuroimaging, therapeutic efficacy and prognosis of 70 cases were analyzed. Methods A retrospective study was made in 70 cases of epilepsy, with detailed case history queried and neurological examination performed. Their ictal and interictal EEG and neuroimaging were carefully analyzed and the therapeutic efficacy and prognosis were evaluated. Results Three percent of all the epilepsy cases had vertigo as their aura or main representation. The episode of vertigo had symptoms suggesting the attack of epilepsy, such as breaking out and breaking off suddenly, changing of consciousness, limbs spasm, deflexion of head and eyes, without nystagmus during the episode and no relationship with the change of body position. A high ratio of positive results can be found in the EEG and neuroimaging examination. The lesions are mainly located in frontal, temporal and parietal lobes. Conclusions Based on the clinical manifestation and EEG, epilepsy cases with vertigo as their aura or main representation can be discriminated from other kinds of vertigo. The vestibular cortical location of vertigo are in the area of frontal, temporal and parietal lobes.
