Abstract
Sixteen-channel topographic brain mapping of electroencephalograms of 25 right-handed
males, 9–12 years of age, with attention-deficit-hyperactivity disorder revealed increased
theta (4–7.75 Hz) and decreased beta 1 (12.75–21 Hz) when compared with 27 controls
matched for age and grade level. The differences were greater when patients were tested
for reading and drawing skills, but were decreased when they were at rest during visual
fixation. Although the differences in patients with attention-deficit-hyperactivity
disorder were generalized, increased theta was more prominent in frontal regions,
while beta 1 was significantly decreased in temporal regions. Principal component
analysis was used to combine the variables into 2 components which accounted for 82%
of the total variance. A discriminant function analysis using these components was
able to predict group membership for attention-deficit-hyperactivity disorder patients
80% of the time and 74% for controls. These findings support the use of topographic
electroencephalography for further elucidation of the neurophysiology of attention-deficit-hyperactivity
disorder.
