Double-Blind Placebo-Controlled Randomized Clinical Trial of Neurofeedback for Attention-Deficit/Hyperactivity Disorder With 13 Month Follow-up.

Abstract Objective To determine whether theta/beta-ratio (TBR) electroencephalographic biofeedback (neurofeedback, NF) has a specific effect on attention-deficit/hyperactivity disorder (ADHD) beyond nonspecific benefit. Method In a 2-site double-blind randomized clinical trial, 144 children age 7-10 with rigorously diagnosed moderate/severe ADHD and theta/beta-ratio (TBR) > 4.5 were randomized 3:2 to deliberate TBR downtraining vs. a control of equal duration, intensity, and appearance. Two early dropouts left 142 for modified intent-to-treat analysis. The control utilized pre-recorded EEGs with participant’s artifacts superimposed. Treatment was programmed via internet by an off-site statistician-guided co-investigator. Fidelity was 98.7% by trainers/therapists, 93.2% by NF expert monitor. Primary outcome was parent- and teacher-rated inattention; analysis was mixed-effects regression. Because expense and effort of NF can be justified only by enduring benefit, follow-ups were integrated. Results Blinding was excellent. While both groups showed significant improvement (p Conclusion This study does not support a specific effect of deliberate TBR NF at either treatment end or 13-month follow-up. Participants will be reassessed at 25-month follow-up.
