Abstract

The present study was undertaken to assess the diagnostic value of CT in patients with poststroke epilepsy, related to EEG in revealing the factors contributing to the development of epileptic fits. The EEG and CT results were evaluated in 50 patients with poststroke epilepsy and compared with those of 50 patients without epilepsy after stroke. Cortical and extensive lesions involving the cortex were more frequent among patients with poststroke epilepsy. Sparing of certain parts of cerebral cortex was observed within vasogenic lesion. This type of change was only found in the poststroke epilepsy group and may be responsible for development of epileptic fits. It seems that CT has a higher diagnostic value than EEG in evaluating the risk of development of poststroke epilepsy.

摘要

本研究旨在评估CT对中风后癫痫患者的诊断价值，并与脑电图（EEG）进行比较，以揭示导致癫痫发作的因素。对50例中风后癫痫患者的EEG和CT结果进行了评估，并与50例中风后无癫痫患者的结果进行了比较。中风后癫痫患者中，皮质及累及皮质的广泛性病变更为常见。在血管源性病变内观察到大脑皮质某些部位未受累。这种类型的改变仅在中风后癫痫组中发现，可能是癫痫发作的原因。在评估中风后癫痫发作风险方面，CT似乎比EEG具有更高的诊断价值。
