局部皮质发育不良(Focal cortical dysplasia,FCD)是儿童难治性癫痫的重要病因之一,在年长儿多表现为部位相关的局灶性发作,低龄儿则可表现为痉挛发作及癫痫性脑病的电-临床特征。本文报道1例FCD所致晚发型痉挛患儿的脑电图(EEG)演变及治疗反应,探讨EEG对FCD病因学诊断的作用,以及对抗癫痫药物(AEDs)治疗有效的致痫性FCD的治疗策略。 Focal cortical dysplasia (FCD) is one of the most important causes of intractable epilepsy in children. In older children, it is characterized by site-related focal seizures. In younger children, spastic seizures and epileptic encephalopathy The electrical - clinical features. This article reports the EEG evolution and therapeutic response of a child with late-onset spasticity due to FCD, and the role of EEG in the etiological diagnosis of FCD and the treatment of epileptic FCD that is effective in the treatment of epilepsy drugs (AEDs) Strategy.
