Objective To analyze the recurrence risk of patients single post-stroke epilepsy. Methods Fifty-eight cases of epilepsy after stroke in Pinggu District Hospital of Beijing were enrolled in this study and their history clinical information were retrospectively collected. All patients were divided into single attack group (A group)and two or more attack group(B group). Results There were 3. 67%(58/1580)stroke patients were developed epilepsy. Among them,0. 38%(6/58)of patients were developed seizures in early stage,and 3. 29%(52/58)in late stage. Thirty-one cases occurred epilepsy once within one years in A group and 27 cases occurred epilepsy more than twice with one year in B group. Initiate epilepsy onset of 2 cases(A1)was at early stage and 29 cases(A2)at late stage in A group. Initiate epilepsy onset of 3 case(B1)was at early stage and 24 cases(B2)at late stage in B group. There was no significant difference in term of types of epilepsy between two groups(χ2 =0. 001,P﹥0. 05). The lesions site of 13 cases was located cortex and 18 cases was located in below cortex in A group,in B group,the lesions site was located in cortex of 17 cases or below cortex of 10 cases,and the difference was not significant(χ2 =2. 555,P﹥0. 05). The hemorrhagic stroke and ischemic stroke were 12 and 19 cases in A group,10 and 17 cases in B group,and there was no significant difference between two groups (χ2 =0. 017,P﹥0. 05). Rhythm of slow wave and the epileptiform discharges were 11 and 2 cases in A group, 11 and 13 cases in B group. About 51. 8% of the patients with recurrence of epilepsy had history of infection in B group. Conclusion For stroke patients,especially hemorrhagic stroke,first seizure is late-onset epilepsy cases. If the electrical activity of the brain is abnormal slow rhythm or epileptiform discharges,close to the cortex is more likely to cause epilepsy recurrence. It is supposed to giving positive antiepileptic drug treatment in the first epilepsy after stroke.
