76例抽动障碍患儿脑电图及临床特征分析

摘要

Objective To observe the electroencephalogram(EEG) manifestations and clinical features of children with tic disorders. Methods Compare the differences of EEG manifestations between children with tic disorders and control group. Also, the EEG manifestations of different clinical types were analysised. Results Among the 76 cases, EEG manifestations of 39 were normal (51. 3%), and 37 cases abnormal (48. 7%). The abnormal percentage of EEG in TTD was statistically lower than that of CTD and TS(P＜0. 05). In addition, sharp wave and sharp-slow wave complex were found mainly in EEG of children with CTD. Conclusion The abnormalities of EEG in children with TD is related to clinical types, which can provide referenced evidence for clinical duration and types of TD children.%目的 分析抽动障碍(Tic Disorders,TD)患儿脑电图(Electroencephalogram,EEG)表现及其临床特征.方法 对76例TD患儿及90例健康儿童脑电图进行比较分析,并比较不同临床类型抽动障碍患儿脑电图的差异.结果 76例TD患儿中EEG正常39例,占51.3％,异常35例,占48.7％；短暂抽动症(Transient Tic Disorders,TTD)患儿脑电图异常率明显低于慢性抽动症患儿(Chronic Tic Disorders,CTD)及多发性抽动症患儿(Tourette Syndrome,TS)(P＜0.05),此外,尖波,尖慢综合波多见于慢性抽动症患儿.结论 TD患儿有较高EEG异常率,脑电图异常率与临床类型有一定关系,可作为TD诊断及提示病程及临床类型的参考依据.
