Epileptic seizure after stroke in Chinese patients.
This was a hospital-based cohort study aiming at determining the occurrence rate of post-stroke seizures and the associated risk factors. From 27 July 1996 to 16 June 1998, the first 1000 consecutive patients in the acute stroke registry were retrospectively reviewed for one year after acute stroke to identify seizure occurrence. The demographic data, seizure onset time, seizure type, drug treatment, response to medication, electroencephalogram findings and cranial computed tomogram findings were collected. Thirty-four patients (3.4%) developed seizure within one year after acute stroke. Univariate analysis revealed that male, age greater than 65 years, total anterior circulation infarction, partial anterior circulation infarction, cortical location and large lesion were significantly associated with post-stroke seizure while multivariate analysis showed that only male (adjusted OR 3.21, p<0.01) and cortical location (adjusted OR 3.83, p<0.05) were significant independent risk factors. Fifty-six percent of early seizures were partial type whereas 72% of late seizures were generalized tonic-clonic type of undetermined onset. Seizures occurred in 3.4% of patients within one year after the onset of stroke. This percentage of seizure occurrence and associated risk factors were similar to other studies. However, intracerebral and subarachnoid haemorrhage were not shown to be risk factors in our study.
