Objective To investigate the change of quantitative electroencephalography(QEEG) in children with attention-deficit hyperactivity disorder(ADHD). Methods A total of 37 children with ADHD and 30 age-matched controls were included.EEG was recorded during eyes-closed resting condition and Fourier transformed to provide estimates for absolute and relative power in alpha-1,alpha-2,alpha-3,beta,theta frequency bands and alpha-L/alpha-R,theta/alpha,theta/beta. Results Compared with controls,ADHD group was found to have more theta and delta activity,alpha and beta activity were different in different brain region,ADHD groups had higher beta/alpha and higher theta/alpha,control group was found to have higher alpha-L/alpha-R in frontal area. Conclusion There are differences on electroencephalography between ADHD children and controls.
