Children with learning disorders (LD) perform below average in tests of academic abilities and intelligence. These children also have a significantly abnormal resting-state electroencephalogram (EEG) compared to typical development (TD), i.e., an excess slow brain oscillations such as delta theta that may be markers inefficient cognitive processing. We aimed explore the relationship between performance intelligence test EEG power spectrum LD. Ninety-one LD 45 control TD were evaluated Wechsler Intelligence Scale for 4th Edition (WISC-IV) 19-channel during eyes-closed condition. The dimensionality was reduced principal component analysis yielded several components representing bands functional meaning. first seven values analyzed multiple linear regression between-group discriminant analysis. related children's intelligence, predicting 13.1% IQ variance. Generalized inversely IQ, whereas frontoparietal gamma activity directly related. resting state had combined 82.4% success rate discriminate those LDs.
