77例婴儿痉挛症的脑电图与临床

THE EEG AND CLINICAL FEATURES OF 77 CASES INFANTILE SPASM

本文报道77例婴儿痉挛症EEG,首次异常率为94.8％。其中,典型高峰节律紊乱波型60例(82.2％),变异型13例(17.8％)。观察表明典型波型患儿临床疗效稍好、智能迟缓程度相对较轻。EEG随访发现,恢复正常者疗效及智能发育较好,反之较差。文中还讨论了同步性增强型及不对称变异型出现的可能原因。

In this paper, the changes in EEG were reported in 77 cases of infantile spasm, at initial record, it was observed that the EEG abnormality was 94. 8% (73 cases). In which,the typical hypsoarrhythmia pattern manifestation was demonstrated to be 82. 2%(60 cases) and the variable pattern 17. 8% (13 cases). Clinical observation showed that curative effect was better and the appearance of their mental retardation was milder in affected children with typical hypsoarrhythmia pattern. In EEG follow-up observation, children with EEG restoration to normality had a better curative effect and a relatively good mental development. Otherwise, it was worse. Finally, the authors also discussed the possible causes for the appearance of synchronous enhancement and asymmetry pattern in EEG manifestations.
