异常睡眠纺锤波与婴幼儿智能障碍的相关性研究

THE RESEARCH OF THE RELATIONSHIP BETWEEN ABNORMAL SLEEP SPINDLES WAVE AND INFANTS' MENTAL RETARDATION

目的:探讨异常睡眠纺锤波与婴幼儿智能障碍的关系。方法:利用动态脑电图仪对100例智力测验低于70的婴幼儿(试验组)进行24小时脑电图监测,同时与100例智力测验大于70的婴幼儿(对照组)进行对照分析。结果:试验组中睡眠纺锤波形成不良且量少59例(59%);睡眠纺锤波缺失9例(9%),其中,单侧缺失6例(67%),双侧缺失3例(33%);极度纺锤波28例(28%);睡眠纺锤波正常4例,异常率96%。对照组中极度纺锤波2例,异常率2%,明显低于试验组。结论:异常睡眠纺锤波与婴幼儿智能障碍密切相关。

Objective： To explore the relationship between abnormal sleep spindles wave and infants＇mental retardation.Methods：We use the ambulatory EEG machine to do the 24-hours monitoring of 100 infants（test group）who is smaller than 70 in the intelligence tests and contrasted with another 100 infants（control group） who is larger than 70. Results：In the test group, there are 59 cases（59%） of sleep spindles wave absence , with 6 cases（67%）unilateral missing and 3 cases（33%） bilateral missing;28 cases （28%） of extreme spindles wave; 4 cases of normal sleep spindles wave.The abnormal rate is 96%. In the control group , there are 2 cases of extreme spindles wave, the abnormal rate was 2% ,which is apparently lower than the test group. Conclusion：Abnormal sleep spindles wave is closely related to the infants mental retardation.
