Electroencephalographic abnormalities of children with hyperkinetic behavior

Abstract
Thirty percent of waking electroencephalograms in childrens exhibiting hyperkinetic behavior disorders without other evidence of central nervous system disease are clearly abnormal. Another 60% of tracings show mild disorder which might be considered abnormal by some electro-encephalographers. Fifty percent of waking electroencephalograms in children exhibiting hyperkinetic behavior and evidence of other central nervous system disease are clearly abnormal. A further 40% of tracing show mild dysrhythmias. The incidences of paroxysmal, slow, and focal abnormalities in both groups are contrasted.
