Background:
Post-stroke seizure (PSS) is a common considerable complication of acute ischemic stroke (AIS). Early risk assessment can clinical practitioners to plan effective prevention and management. We aimed to determine whether assessing Diffusion-Weighted Imaging-Alberta Stroke Program Early CT Score (DWI-ASPECTS), and neutrophil indices allows for identifying patients at risk of PSS.
Methods:
This prospective study included AIS patients with cortical involvement admitted to a single academic center between January 2020 to October 2023. For all included subjects, DWI-Brain MRI, blood neutrophils, and platelet counts were obtained and the DWI-ASPECTS score was calculated. Then, the patients were followed up for 6 months in terms of PSS occurrence. Based on the occurrence of PSS, patients were divided into two groups of PSS and non-PSS. For analysis, imaging and laboratory data were compared between two groups. Logistic regression was applied to determine the relationship between DWI-ASPECTS and neutrophil indices, with early PSS. Finally, the sensitivity and specificity of these variables for PSS were estimated.
Results:
A total of 309 were included in the final statistical analysis. DWI-ASPECT and neutrophil-to-lymphocyte ratio (NLR) were significantly associated with early PSS with OR of 0.74 and OR of 1.13, respectively (P < 0.05). Further analysis showed that, a combination of DWI-ASPECTS, NLR had an area under the curve (AUC) of 0.72 for predicting the occurrence of early PSS.
Conclusion:
DWI-ASPECTS and NLR are associated with the occurrence of early PSS after cortical ischemic stroke. A combination of these predictors had higher sensitivity and specificity for PSS rather than each factor alone. These findings may be helpful for determining the risk of PSS if validated in future studies.
