Objective: To describe clinical features and magnetic resonance imaging findings of post-stroke epileptic patients at Neurology Center of Bachmai Hospital.
Subjects: 131 patients diagnosed with poststroke epilepsy at Bachmai Hospital from June 2020 to July 2023.
Methods: Cross-sectional descriptive study.
Results: Male/female ratio is 3.6, mean age is 58,8±15,8. Ischemic stroke accounted for 72.3% while had hemorrhages. Hemiplegia is the most common feature, accounting for 63.1%. The first epileptic seizure occurred almost within one year after the onset of stroke, accounting for 73.9%. Focal seizure is the most common seizure type, accounting for 78.2%; Unknown seizure is 16.5%; and 5.3% had generalized seizures. In brain magnetic resonance imaging (MRI), 60% of patients had lesions in the left hemisphere, 36.9% in the right hemisphere, and 3.1% in both hemispheres. In these patients, ischemic stroke and hemorrhage stroke are 71.8% and 28.2%, respectively—Approximately 83.2% of the lesions involved cortical areas. A hemorrhage stroke has a higher risk of having an early seizure.
Conclusion: Stroke is the leading cause of epilepsy with the elderly who was over 60 years old. The most common seizures type occuring after stroke were within one year of onset, of which focal seizures were the main ones. Magnetic resonance imaging shows most PSE patients had the involvement of cerebral cortex. Haemorrhage stroke has a higher risk of occuring early seizure with statistically significance.
