老年性癫癎的临床特征和脑电图分析

The clinical and electroencephalographic characteristics of epilepsy in the elderly

目的分析和总结老年性癫癎的临床特征、脑电图特点及临床意义。方法对92例60岁后发病的老年性癫癎患者的临床、脑电图及神经影像学资料等进行分析。结果 92例患者中,复杂部分性发作是最常见的发作类型。82例为症状性癫癎,10例为隐源性癫癎。脑血管病、脑肿瘤、代谢中毒性疾病、颅内感染、脑外伤等是常见病因。脑电图异常以局灶性慢波最常见。56例随访患者中,47例发作控制良好。结论老年人群是癫癎的高发人群,正确认识临床特征和脑电图特点是诊断治疗的关键。

Objective To explore the clincal and electroencephalographic characteristics of. epilepsy in the elderly. Methods Ninety-two patients with epilepsy whose first seizure occurred at over 60 years old were included in this study. Their clinical,electroencephalographic and neuroimaging data were analyzed. Results Complex partial seizure was the most common type. Eighty-two pa- tients were symptomatic epilepsy and ten patients were cryptogenic epilepsy. Accoding to the etiology, cerebrovascular disease, brain tumor, metabolic-toxic disease, intracranial infection and brain trauma were the most common causes. The most frequent finding of EEG was focal slow wave. Fifty-six patients were followed and forty-seven of them had a good response to antiepileptic drugs. Conclusion Old age is the most common time in life to develop epilepsy. Comprehensive diagnosis and therapy are crucial in clinical practice.
