中央区纵裂癫痫症状学和脑电图研究

目的 探讨中央区纵裂癫痫患者症状学表现及视频脑电图、加密电极脑电图、颅内电极脑电图的特征.方法 对2007年6月至2009年8月确诊为中央区纵裂癫痫并经手术治疗的9例患者资料进行回顾性分析.通过病历采集、视频录像及各种脑电图检查记录,汇总分析各例患者的癫痫发作症状和脑电图特点.结果 中央区纵裂癫痫患者病史长,癫痫发作持续时间短,发作频繁而智力受损不明显,多伴有下肢过度运动发作.头皮脑电图显示中线区域放电,波幅低平.纵裂内皮质脑电显示超高波幅节律规整的慢尖波.全部患者术后均达Engel Ⅰ级.结论 中央区纵裂癫痫患者癫痫发作症状特异,各种脑电图在不同时相、波幅、节律、导联配置等多方面具有独特表现.

The study of symptomatology and electroencephalogram in central region diastematia epilepsy

Objective To explore the clinic symptom and the characteristics of video,tightly close,intracranial electroencephalogram (EEG) of patients with central region diastematia epilepsy. Methods Retrospective analysis of 9 patients with central region diastematia epilepsy admitted from June,2007 to August,2009.The characteristics of all patients' seizure symptom and EEG manifestation were analyzed using patients' medical history,video and EEG records.Results Patients with central region diastematia epilepsy had relatively long sezure history.The duration of seizure was commonly short,with frequent episode and no obvious intelligence impairment.The seizure was often accompanied with the hyperkinesia in the lower limbs.Scalp EEG showed discharges with low amplitude waves in the mean line area.The superhigh amplitude and regular rhythm slow sharp wave could be found in the diastematia cortex EEG.All patients had an Engel Class Ⅰ outcome after surgery.Conclusion The seizure symptoms are characteristic in the patients with central region diastematia epilepsy,and some special manifestations can be found in different phase,wave amplitude,rhythm,lead array.
