在厄瓜多尔北方72121人口的农村地区逐户进行调查癫痫的发病情况。用系统检查确诊这些人口中癫痫发作的人数。共检出1029例患者,其中881例为确诊病例,148例是可疑病例。1029例患者中56％有活动性发作,终生发作率为12.2‰～19.5‰,且活动性发作人数约6.7‰～8.0‰。估计每年发病率是122～190/100000。不用脑电图资料对发作类型分类,几乎有一半病例有不完全性发作。27％的病例可在临床检查出病因。这项调查是研究大量未行抗癫痫药物治疗患者的少数报告之一,对研究未行治疗的自然病史提供了资料。调查提示治疗新发生的癫痫可防止其转变成慢性病。1029例中有27％曾进
In rural areas of 72,121 people in northern Ecuador, the incidence of epilepsy was investigated on a household-by-household basis. The number of people diagnosed with seizures in these populations was systematically examined. A total of 1029 patients were detected, of which 881 were diagnosed and 148 were suspicious cases. 56% of 1029 patients had active seizures with a lifetime lifesaving rate of 12.2 ‰ to 19.5 ‰, and the number of active seizures was 6.7 ‰ ~ 8.0 ‰. The estimated annual incidence is 122 to 190/100000. EEG data are not used to classify the type of seizures, with almost half of all cases having incomplete seizures. 27% of cases can be clinically detected etiology. The survey, one of the few studies that studied a large number of patients not treated with antiepileptic drugs, provided information on the study of untreated natural history. Investigations suggest that treating newly-occurring epilepsy prevents it from becoming chronic. 27% of 1029 patients had progressed
