Abstract
BACKGROUND: Seizures are one of the most common complications of stroke. We aimed to establish the incidence and clinical profile of post-stroke early seizure (ES) in patients with intracerebral hemorrhage (ICH). METHODS: Patients with ICH within 10 days of onset who were admitted to Landseed International Hospital were recruited consecutively between January 1, 2006, and December 31, 2009. The National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale were used to access patients initial stroke severity and functional outcome at discharge, respectively. The occurrence of epileptic seizures within 30 days after onset of the index ICH was recorded. Early post-ICH seizure was defined by the occurrence of clinically identifid seizure episodes or non-epileptic seizure within 7 days after the stroke onset. RESULTS: A total of 297 ICH patients were included. The mean age of the participants was 62 ± 16 years, and 72% of them were male. A total of 9 (3%) participants had seizures during acute hospitalization. Patients with seizures had higher median NIHSS scores at baseline (34 vs. 16, p = 0.004). No difference was noted in the cortical involvement of ICH (22% for patients with seizures and 14% for those without, p = 0.156). Patients with seizures had higher in-hospital mortality ( 56% vs. 23%, p = 0.024). The multivariate Cox regression model showed the factors significantly associated with ES were higher initial NIHSS scores on admission (adjusted odds ratio [aOR] = 1.1 per 1 point increased, 95% confidence interval [CI] = 1.0-1.2) and coronary artery disease (aOR = 7.0, 95% CI = 1.3-36.4). CONCLUSIONS: The NIHSS scores and coronary heart disease were associated with ES in ICH, whereas cortical involvement was not. These findings may reflect difference in post-stroke seizure and primary ICH between Asian and Western populations.
