眼睑肌阵挛失神综合征的临床与脑电图特征

Clinical manifestations and electroencephalographic features of eyelid myoclonia with absences

目的：探讨眼睑肌阵挛失神综合征（EMA）的临床、脑电图（EEG）特点及治疗。方法：回顾我院诊治的2例EMA患者的临床资料，并结合文献分析。结果：2例均为儿童期起病，表现为反复的眼睑肌阵挛，伴或不伴短暂失神，EEG特征为泛化性的、双侧基本对称的2．5～4Hz棘慢波或多棘慢波发放。结论：EMA由于症状复杂，常被漏诊。EEG对EMA的诊断是必需的。

Objective： To explore the clinical manifestations, electroeneephalography （EEG） findings and treatment of eyelid myoclonia with absences （EMA）. Methods： The clinical data of two patients with EMA were analyzed retrospectively, Results： Both patients onsetted in childhood, and presented EMA eyelid myoclonia without transient absences. EEG features of two patients were generalized discharges of paroxysmal 2.5-4 Hz spike and waves or polyspikes and slow waves. Conclusion： EMA is likely to be misdiagnosed due to complicated symptoms. EEG is necessary for diagnosis of EMA.
