Electroencephalography—sleep Findings in Cerebral Palsy

EEG sleep records were obtained on 144 children with cerebral palsy (128 spastics and 16 athetoids). The results agree with those of earlier studies. Electroencephalographic tracings taken while the patient is asleep are of definite diagnostic value but are of limited prognostic value. A larger population of athetoids is needed to determine the significance of the continuous high amplitude spindling which was observed. Serial studies should be done on those patients with seizure discharges but without clinical seizures to determine the prognostic significance of such activity in the EEG.
