目的　探讨动态脑电图检查在儿童注意缺陷多动障碍临床诊治中的应用价值。方法　对179例注意缺陷多 动障碍患儿进行常规脑电图检查，其中117例同时行动态脑电图检查并作出评价。 结果　常规脑电图正常162例，异常17 例，其中11例为轻度异常， 6例有痫样活动；异常率9.5%。动态脑电图正常96例，异常21例，其中轻度异常9例，有痫样 活动12例；异常率17.9%。结论　早期运用动态脑电图可以提高注意缺陷多动障碍患儿共患癫痫的检出率，对注意缺陷 多动障碍患儿临床控制病情及改善预后有一定的参考意义。

Objective　To explore the value of active electroencephalography (AEEG) in the diagnosis of  attention-deficit hyperactivity disorder. Methods　Routine EEGs were performed in 179 patients with attention-deficit hyperactivity disorder. AEEGs were performed in 117 patients who have been performed routine EEGs. Results　Abnormal discharge was observed in 17 cases in routine EEGs and epileptiform activities were found in 6 patients. The abnormal rate is 9.5%. Abnormal discharge was observed in 21 cases in AEEGs and epileptiform activities were found in 12 patients. The abnormal rate is 17.9%. Conclusions 　AEEG is an important clinical examination which also serves as a reference for brain function and epilepsy. AEEG could help judge the prognosis of epilepsy comorbiding with attention-deficit hyperactivity disorder.
