【摘要】 检查了１０３名６～１２岁学习困难儿童以及与之配对的１０３名学业良好的儿童的脑电图，结果显示，异常脑电图在两组儿童中分布无显著差异，但学习困难儿童高α波人数及频率小于１０Ｈｚ的人数显著多于对照组，提示常规脑电图检查技术对儿童学习困难无诊断价值，本文结果还提示脑功能成熟相对迟缓可能是儿童学习困难原因之一。更多还原

【Abstract】 The electroencephalographic findins were investigated in 103 children with learning difficulties (LD) and-sex-matched controls(had a good aaemic achievement) aged 6～12 years old. The results vealed that children with LD had significantly lower frequency and higher amplitude alpha wave. There were fewer ones with alpha wave above 10Hz in learning disabled children than those in controls Borderline and abnormal EEG were not significantly more frequent in LD than in control children. The significance of the results were discussed.更多还原
