【摘要】 目的：探讨老年人迟发性癫 发作的临床及脑电图特点。方法：回顾性分析８０例老年人迟发性癫 的临床及脑电图资料。结果：癫 发作的可能原因为脑血管病４１例（脑梗死３０例、脑出血１１例），脑肿瘤１９例，脑外伤 ４例，脑萎缩 ８例。癫　发作的类型为全身强直阵挛发作 ４８例；强直阵挛发作持续状态２例，失神发作６例，单纯运动性发作１７例，单纯体感性发作７例。脑电图正常７例，异常７３例。异常脑电图主要表现为弥漫性慢波活动２２例，局限于一侧半球的慢波活动３４例，散在或阵发性棘波、尖波或棘慢、尖慢综合波４９例。结论：脑血管病（脑梗死、脑出血）、脑肿瘤是老年迟发性癫　发作的主要原因。癫　发作以全身强直阵挛发作为主。脑电图异常率高，主要表现为在弥漫性慢波活动基础上出现癫　样放电。更多还原

【Abstract】 Objective: To explore the characteristics of clinical manifestations and EEGs in old patients with late onset epileptic seizures. Methods: Clinical and EEC data of 80 old patients with epilepsy were analyzed retrospec- tively. Results: The probable causes of epileptic seizures included 41 cases of cerebral vascular disease( cerebral in- farction and cerebral haemmohrage) ,19 brain tumors, 4 brain trauma and 8 brain atrophy. The types of epileptic sei- zures included 48 generalized tonic-clonic seizures, 2 tonic-clonic epilepticus, 6 absence seizures, 17 simple partial motor seizures and 7 simple somatosensory seizures. Normal EEGs were found in 7 patients and abnormal ones in 73 patients. The abnormal EEGs mainly showed diffuse slow waves in 22 patients, slow waves localized in one hemi- sphere in 34, epileptiform discharges in 49 patients. Conclusions: Cerebral vascular disease and brain tumor might be the main causes of old patients with late onset epileptic seizrues. The seizure types mainly showed generalized tonic- clonic seizures. EEG changes mainly showed epileptiform discharges on the background of diffuse slow waves.更多还原
