The electroencephalograms (EEGs) of infants and children are normally characterized by a greater mixture of waveforms and frequencies than is found in adults.The relative predominance of these wave types varies with age. There may be considerable intersubject variability, | The electroencephalograms (EEGs) of infants and children are normally characterized by a greater mixture of waveforms and frequencies than is found in adults.The relative predominance of these wave types varies with age.

Several waveforms, such as the initial response to hyperventilation and posterior slow rhythms of youth, may be normally asymmetrical. | Several waveforms, such as the initial response to hyperventilation and posterior slow rhythms of youth, may be normally asymmetrical. | ||

Moreover, infants and young children tend to become drowsy during the recording, and the electrographic alterations with drowsiness are greater than those with adults. These factors create wider limits of normality than might be expected in adults. In addition, the superimposition of two or more waveforms often creates sharply contoured waves that can be mistaken for spikes.
