癫痫性脑病(EES)是一组与严重的癫痫源性的脑部疾患,伴随进行性加剧的认知和行为障碍。EES发生认知障碍的机制目前尚不甚明了。本文对癫痫性脑病脑功能的神经影像学研究进行综述。尽管癫痫活动可能单独起源于不同脑区,但癫痫活动似乎以综合征的特定的方式进行传播。在部分癫痫性脑病中发现,癫痫的异常放电与脑默认网络的中断密切相关。对于其他类型的癫痫,尚有其他机制认为癫痫异常活动与认知障碍相关,如异常的连接模式及丘脑皮层网络连接的活动受抑。对于功能影像学对于癫痫异常活动的传播机制及对认知功能影像尚需要进一步深入研究。
癲癇性腦病(EES)是一組與嚴重的癲癇源性的腦部疾患,伴隨進行性加劇的認知和行為障礙。EES髮生認知障礙的機製目前尚不甚明瞭。本文對癲癇性腦病腦功能的神經影像學研究進行綜述。儘管癲癇活動可能單獨起源于不同腦區,但癲癇活動似乎以綜閤徵的特定的方式進行傳播。在部分癲癇性腦病中髮現,癲癇的異常放電與腦默認網絡的中斷密切相關。對于其他類型的癲癇,尚有其他機製認為癲癇異常活動與認知障礙相關,如異常的連接模式及丘腦皮層網絡連接的活動受抑。對于功能影像學對于癲癇異常活動的傳播機製及對認知功能影像尚需要進一步深入研究。

Epileptic encephalopathies (EEs) represent a group of severe epileptic disorders associated with cognitive and behavioral disturbances. The mechanisms of cognitive disability in EEs remain unclear. This review summarized neuroimaging studies that have tried to describe specific fingerprints of brain activation in EE. Although the epileptic activity can be generated individual y in different brain regions, it seems likely that the activity propagates in a syndrome-specific way. In some EEs, the epileptiform discharges were associated with an interruption of activity in the default mode network. In another EE, other mechanisms seem to underlie cognitive disability associated with epileptic activity, for example, abnormal connectivity pattern or interfering activity in the thalamocortical network. Further neuroimaging studies are needed to investigate the short-term and long-term impact of epileptic activity on cognition and development.
