PURPOSE: We compared clinical characteristics and outcomes of the early-onset seizure post-stroke patients who had seizures occurring at stroke presentation (SSP) with other patients without SSP at a single institution in Eastern China.
METHODS: We reviewed 20,947 ischemic stroke patients in our hospital electronic medical records system from January 2007 to December 2016. Among them, there were 91 (0.43%) patients with early-onset seizure post-stroke. Among these 91 patients, there were 35 (0.16%) SSP patients and another 56 (0.27%) were designated as non SSP patients because they also had early-onset seizure post-stroke, but without SSP. We compared the clinical presentations of the SSP patients with those of the non SSP patients including baseline stroke risk factors, and 10-year Kaplan-Meier death risk after their first stroke.
RESULTS: In the SSP patients, 25.7% of them presented with posterior circulation infarction, whereas only 12.5% of the non SSP patients had this condition (P<0.05). In contrast, 17.1% of the SSP patients were being treated with antiepileptic drugs at discharge whereas 37.5% of the non SSP patients received such treatment (P<0.05). The percentage of SSP patients with temporal lobe lesions was less than in non SSP patients (P<0.05). However, brain stem and thalamus lesions were more frequently seen in SSP patients than non in SSP patients (P<0.05). The risk factors for ischemic stroke including a history of hypertension, diabetes mellitus, hyperlipidemia and atrial fibrillation were the same in these two groups (P>0.05). In the SSP patients group, the 10-year risk of death was 36.9% after the initial seizure incident, and in the non SSP patients group, the 10-year death risk was 40.1%, but this difference between the two groups was not significant (P>0.05).
CONCLUSIONS: Ischemic stroke patients with SSP had some unique signs that included a higher incidence of posterior circulation infarction than non SSP patients.
