目的 探讨伴中央 -颞区棘波放电的儿童良性癫痫 (BECCT)的临床特点及脑电图特征。方法 对 2 0例 BECCT患者的临床及脑电图改变进行分析。结果 BECCT主要表现为发作性肢体阵挛或强直、面肌抽搐、口唇运动、流涎、咽喉发声、部分语言障碍但神志清楚 ,发作与睡眠关系密切。脑电图背景活动正常 ,局限性棘波或尖波灶位于中央区或中颞区 ,可扩散至其它部位 ,清醒时较为局限 ,入睡后放电频度明显增加。神经系统检查未发现异常。预后良好。结论 BECCT是一种特征性癫痫综合征 ,临床常见 ,及时而正确的诊断有助于治疗及判断预后。
Objective To investigate the clinical features and EEG features of benign epilepsy (BECCT) in children with central-temporal spike discharge. Methods The clinical and EEG changes of 20 BECCT patients were analyzed. Results BECCT mainly manifested as episodic limbs clonic or ankylosis, facial muscle twitching, lip movements, salivation, throat sound, but some conscious language disorders, seizures and sleep closely. EEG background activity is normal, limited spikes or sharp wave focus in the central area or in the temporal region, can spread to other parts, more limited when awake, discharge frequency increased significantly after falling asleep. Nervous system examination found no abnormalities. The prognosis is good. Conclusion BECCT is a characteristic epilepsy syndrome, clinical common, timely and correct diagnosis is helpful to the treatment and prognosis.
