Abstract

Objectives: This study investigated age-related changes and sex differences in the EEGs of two groups of children with attention-deficit/hyperactivity disorder (ADHD) combined type and ADHD predominantly inattentive type, incomparison with a control group of normal children. Methods: Forty boys and forty girls were included in each group. The EEG was recorded during an eyes-closed resting condition and Fourier transformedto provide estimates for total power, absolute and relative power in the delta, theta, alpha and beta bands, and for theta/alpha and theta/beta ratios. Results: Total power, relative alpha, and the theta/alpha and theta/beta ratios were differentiated between all 3 groups. Sex differences between theADHD subjects and the control group were greater in males than females andmatured faster in males. With increasing age, the EEG of the ADHD inattentive group was found to change at a similar rate to the changes found in thenormal group, with the differences in power levels remaining constant. In the ADHD combined group, the power was found to change at a greater rate than in the ADHD inattentive group, with power levels of the two ADHD groups becoming similar with age. Conclusions: These results are supportive of a two-component model of ADHD, with the hyperactive/impulsive component maturing with age and the inattentive component remaining more stable.
