Researchers from Nantong First People's Hospital, Jiangsu, China, explored the effectiveness of electroencephalographic (EEG) biofeedback therapy for ADHD in children, by assessing the changes of the ratio of brain theta to beta waves (when the children fulfill cognition tasks, brain theta wave activity increases and beta wave activity weakens), and by using the IVA-CPT (integrated visual and auditory continuous performance test) as an assessment measure.
EEG biofeedback therapy was performed in 30 children with ADHD. After
two courses of treatment, the mean ratio of brain theta to beta waves
in the 30 children with ADHD was significantly reduced from
12.32+/-4.35 before treatment to 6.54+/-1.27 (p<0.01) after. The
IVA-CPT revealed that six measures were significantly improved after
biofeedback therapy (p<0.01), including reaction control, attention
control, auditory & visual reaction control, and auditory &
visual attention control.
The study concludes that EEG biofeedback can reduce the ratio of brain
theta to beta waves, and lead to significant decreases in inattention
and hyperactivity. It is an effective treatment for ADHD in children.
