Objective: To describe the risk factors of post stroke epilepsy through analysis of clinical and electroencephalogram (EEG) characteristics at the Neurology Center of Bach Mai Hospital. Subjects: 131 patients diagnosed with epilepsy after stroke at Bach Mai Hospital from June 2020 to July 2023. Method: Cross-sectional study Results: The male/female ratio was 3.6, the average age was 58.8±15.8. The unprovoked seizures occurred mainly within 1 year after stroke onset, accounting for 74.0%; the focal onset seizures were mainly 77.9%; the generalized seizure were 5.3%; the unclassified seizures were 16.8%. Normal EEG accounted for 46.6%. NIHSS score (p = 0.027; OR = 5.09) was significantly correlated with the risk of post-stroke epilepsy. Intracerebral hemorrhage was significantly correlated with the onset of symptomatic seizures. Conclusion: Stroke is the leading cause of epilepsy in the elderly who are over 60 years old. The post-stroke seizures occurred mainly during one year from stroke onset, in which focal seizures are the most common type. Most patients with epilepsy after stroke had lesions extending to the cerebral cortex. Severe stroke is a risk factor for post-stroke epilepsy. Cerebral hemorrhage has a significantly higher risk of symptomatic seizures.
