目的探讨颞叶癫患者发作期临床特征、脑电图特点及其临床意义。方法对14例患者的46次发作的临床特点及脑电图进行分析。结果46次发作中,16次为单纯部分性发作,30次为复杂部分性发作,2次继发全面性发作,单纯部分发作频率高而持续时间短,复杂部分发作持续时间长但发作频率低并常见发作后朦胧状态。发作时脑电图表现以中高波幅慢波起始最多见,10例患者可以得到定侧。4例患者通过分析临床表现及脑电图改变定侧后进行手术,术后癫完全控制。结论颞叶癫是一组部分性症状性癫综合症,多表现为复杂部分发作,临床医生通过监测到临床发作可以更好明确诊断。同时,临床发作及同步脑电图改变可以为术前评估提供很大帮助。
Objective To investigate the clinical features, EEG features and clinical significance of patients with temporal lobe epilepsy. Methods The clinical features and electroencephalogram of 46 seizures in 14 patients were analyzed. Results Of the 46 episodes, 16 were simple partial seizures, 30 were complicated partial seizures and 2 were secondary seizures. The simple partial seizure frequency was high and the duration was short. In the complex seizure, the seizure duration was long but seizure frequency was low And common after the hazy state of attack. The onset of EEG showed high to moderate amplitude slow wave onset of the most common, 10 patients can get set side. Four patients underwent surgery after analysis of clinical manifestations and electroencephalographic changes, and postoperative epilepsy was completely controlled. Conclusion Temporal lobe epilepsy is a group of partial symptomatic epilepsy syndrome, which is characterized by complicated partial seizures. Clinicians can better confirm the diagnosis by detecting the clinical seizures. At the same time, clinical seizures and changes in synchronized EEG can provide great help in preoperative assessment.
