A clinical analysis of epilepsy secondary to stroke

Abstract

Objective To explore the clinical manifestations, features, pathogenesis, and treatment of epilepsy secondary to stroke. Methods The seizure location and features, types, and treatment of epileptic seizures were retrospectively analyzed in 46 storoke patients with epilepsy. Results The incidence of epilepsy secondary to stroke was 6.1% (46/754). 39 of 754 patients (5.2%) developed early-onset epilepsy and the remaining 7 (0.9%) occurred late-onset epilepsy. 78.2% (36/46) was cortex epilepsy and 21.8% (10/46) was posterior cortex epilepsy. In early-onset epilepsy, generalized tonic-clonic seizure occurred in 30 patients and partial seizure in 9; while in late-onset epilepsy, 2 patients presented with generalized seizure and 5 with partial seizure. Cortex epilepsy was more common than posterior cortex epilepsy (P＜0.05). The prognosis was worse in stroke patients with epilepsy than those without epilepsy.Conclusions Cortex epilepsy secondary to epilepsy is common. Early-oneset epilepsy mainly presents with generalized tonic-clonic seizure and late-onset epilepsy presents with partial seizure. Early control of seizures is beneficial for patient recovery.
