Background:
Post-stroke epilepsy (PSE) is one of the major sequelae of stroke. Inflammation has been implicated in the development of stroke. The study aimed to explore the relationship between neutrophil-to-lymphocyte ratio (NLR) levels and epilepsy in patients with primary intracerebral hemorrhage (ICH).
Methods:
A retrospective study was performed on 1132 patients with first-time ICH. Blood samples were obtained at admission after ICH. Patients included in the study were classified into three groups according to NLR tertiles. Logistic regression was used to analyze the relationship between NLR levels and the occurrence of PSE.
Results:
The occurrence of PSE was significantly correlated with NLR levels (r = 0.118, P < 0.001). Patients with PSE had higher NLR levels than those without PSE. After adjusting for potential confounders, high NLR was independently associated with an increased risk of PSE (OR = 1.861, 95% CI 1.032-3.355, P = 0.039). Neutrophil-to-lymphocyte ratio levels were independently associated with the occurrence of PSE in the poor functional outcome group, while this association was not significant in the favorable functional outcome group. The model (cortical involvement + hematoma volume + early seizures + NLR) showed good prognostic performance.
Conclusion:
High NLR at admission is associated with an increased risk of PSE, which suggests that NLR may play a role in risk stratification in patients with ICH.
