Independent of the administration of MPH ADHD children of the inattentive type showed a hemispheric asymmetry with higher global power amplitudes in the left hemisphere compared to the right hemisphere (p = 0.04). They also had higher global power amplitudes left hemispheric than ADHD children of the combined type (p = 0.07).Back to article page
