对 32 0例以癫痫发作为首发症状病人的病因进行回顾性分析。病因与发病时间的相关分析显示 :急性癫痫组和慢性癫痫组的主要病因不同。不同分组方式的病因构成比分析显示 :不同的年龄、发作类型组的主要病因分布均有非常显著性差异 (P =0 .0 0 )。提示 :癫痫发作在许多疾病中均可出现 ,病因复杂 ,但有其内在规律。不同的发病年龄、发作形式、病因与发病时间的相关性等因素与病因学之间的内在联系 ,对癫痫的病因诊断有一定指导意义。 A retrospective analysis of the causes of 32 patients with seizures as the first symptom was performed. The etiology and onset time of the correlation analysis showed that: the main causes of acute epilepsy group and chronic epilepsy group. Etiology analysis of different groups showed that there were significant differences in the distribution of the major etiologies between the different age groups (P = .0 0). Tip: Epileptic seizures can occur in many diseases, the etiology is complex, but has its inherent laws. Different age of onset, the form of attack, the relationship between etiology and time of onset and other factors and the etiology of the intrinsic link between the etiological diagnosis of epilepsy has a guiding significance.
