EEG sleep of normal healthy children. Part I: Findings using standard measurement methods.

Despite the increasing application of all-night electroencephalographic (EEG) sleep studies to children for clinical as well as for research purposes, readily available normal EEG sleep standards for the period of childhood have remained sparse and, at present, reflect data on only approximately 100 children 6 to 16 years of age. As part of a large scale study examining various aspects of EEG sleep among children, findings derived using standard recording and scoring methods are reported for a new sample of nearly 100 normal, healthy children and are compared with existing standards. Data obtained add substantially to the existing database and generally confirm findings of previous normative reports on children in this age range.
