Epileptic Seizures After Cerebrovascular Disease

Abstract

Epileptic seizure following cerebrovascular disease (CVD) is not rare. In this study, we retrospectively investigated the risk of seizure due to CVD and correlated the epileptic seizures with localisation and type of lesion, mortality rate. We also evaluated to detect the relation of nature of the seizure to the seizure onset. The incidance of epilepsy in CVD patients was 16%. CT scan or MRI shbwed ischaemic lesions in 169 (62%) and haemorrhagic lesions in 103 (38%) patients. These results revealed no signifırnntrelationship between the patients with seizure and ones without seizures. 52% of patients with seizure were identifıed as embolic, 38% were thrombotic. The lesion localisation which we most frequently saw in our study was cortical and cortico-subcortical (60%) . Early seizures and generalised tonic-clonic seizures (GTC) were most frequently observed. During hospitalisation, the mortality rate was 18% in nonepileptic cases and 20% in epileptic cases. In conclusion, cortical lesions and embolic infarctswere increasing the risk of epileptic fits. The generalised tonic-clonic seizures were most frequently seen in our patients and patients of the study revealed no significant relationship between the frequency of seizures and the rate of mortality.
