癫痫的自发缓解

Spontaneous remission of epilepsy

904例癫痫患者中,448例未经治疗,其中自发缓解2年以上占40.4％;自发缓解5年以上占27.1％。容易发生自发缓解的因素有:20岁以前起病,发作频率少于每月一次、原发性癫痫、病程短、无外因和神经精神缺陷、发作类型为失神发作、未分类型或复杂部份型。

A multi-institutional door-to-door neuroepidemiological survey of rural and minority areas in twentyone provinces of China was conducted and a total sample of 246 812 population were included. The definition of epilepsy referred to two or more than two times afebrile seizures, and these seizures have no relation to acute metabolic disorders, alcohol and anesthetics. Spontaneous remission referred to that epileptics had received no treatment but seizures had disappeared for more than two yeas. In this study. the frequency of epilepsy is expressed in term of a lifetime point prevalence ratio (prevalence day January 1 1985). There were 904 individuals identified as suf(?)ering from epilepsy, yielding a lifetime point prevalence of 366 per 100,000 population, or 3.7 per 1 000, and an age-adjusted to the 1960 U.S. population prevalence ratio of 3.6 per 1 000, In 904 epileptics, there were 448 cases who had received no treatment, of whom 40.4%, had remitted more than two years, and 27.1% remited more than five years. According to this series, the available factors to spontaneous remission are: onset before twenty years, frequency of seizure less than once a month, primary epilepsy, sort duration of epilepsy, no exogenous etiology and neurological- psychiatric. defects, absence, unclassificate(?) type or complex partial seizure.
