Brain Function in Problem Children and Controls: Psychometric, Neurological, and Electroencephalographic Comparisons

Psychometric, neurological, and EEG studies were made of 24 children with scholastic-behavioral problems but no classical evidence of neurological disease and of 24 matched controls. Differences between the two groups were significant in all three measures, giving evidence of brain dysfunction in the groups with scholastic-behavioral problems. Two subgroups—hyperactive and nonhyperactive—each with characteristics suggesting a different syndrome, are described.
