Risk Factors of Epilepsy After Stroke in Children / 대한소아신경학회지

ABSTRACT

PURPOSE: Post-stroke seizures and epilepsy were mainly studied in adults. Selected groups of children with stroke were studied to evaluate the incidence of seizures and epilepsy and the risk factors of epilepsy after stroke. METHODS: Seventy consecutive stroke children younger than 15 years of age were retrospectively reviewed to evaluate the incidence, times, causes of epilepsy and the risk factors epilepsy after stroke. The number and location of the lesion as imaged on the CT scan, and MRI scan were determined. RESULTS: Epilepsy after stroke was diagnosed in 38(54.3%) of 70 stroke patients16 (45.7%) of 35 with hemorrhagic stroke and 22(62.9%) of 35 with ischemic stroke. Arteriovenous malformation(18), vitamin K deficiency(7), hemophilia(5) were frequent causes in hemorrhagic stroke, and idiopathic(15), moyamoya disease(11), hemiconvulsion-hemiplegia-epilepsy syndrome(6) were frequent in ischemic stroke. No statistically significant differences were noted with relation to sex, type of stroke, number of the lobar lesions, between cortical and subcortical lesions and onset time of initial seizure. Epilepsy developed more often in patients who had lesions located in the left cerebral hemisphere (76.7%) than on the right(42.3%)(P<0.01). CONCLUSION: Epilepsy developed more often in children who had lesion located in left cerebral hemisphere. No statistically significant differences noted in relation to sex, type of stroke, number of the lobar lesions and between cortical and subcortical lesions.
