The Clinical Features of the Postinfarction Seizure

ABSTRACT

OBJECTIVE: We reviewed the clinical features of the patients with postinfarction seizure to evaluate the high risk factors of postinfarction seizure. METHOD: We retrospectively studied 81 patients with post infarction seizures to determine the clinical features (onset, type of seizure, etc.) with their clinical recordings, electroencephalographic (EEG), and computed tomographic (CT) or magnetic resonance imaging (MRI) findings. RESULTS: Patients comprised 49 men and 32 women with their ages ranged from 31 to 87 (mean 64.7) years. After cerebral infarction, 31 patients experienced seizures within 2 weeks and 50 patients more than 2 weeks. Generalized tonic-clonic and simple partial seizures were the most common type of seizure. 40 patients showed focal slowing on EEG. The most common location of the cerebral infarction was cortical area and frequently involved lobes were frontal and temporal lobes. The recurrent seizure was not associated with seizure onset duration, seizure type, EEG finding, or location of infarction. The size of cerebral infarction was significantly associated with recurrent seizure but not associated with first-attack seizure. CONCLUSION: This results would be helpful for prevention and treatment of postinfarction seizures.
