For Which Children with ADHD is TBR Neurofeedback Effective? Comorbidity as a Moderator

Area of Science:

• Neuroscience
• Child Psychology
• Clinical Psychology

Background:

• Attention deficit hyperactivity disorder (ADHD) often presents with psychiatric comorbidities.
• Neurofeedback (NF) is a potential treatment for ADHD, but its efficacy may be influenced by co-occurring conditions.
• Theta/beta-ratio (TBR) neurofeedback specifically targets brainwave activity associated with ADHD.

Purpose of the Study:

• To investigate how psychiatric comorbidities moderate the effectiveness of TBR neurofeedback in children with ADHD.
• To compare the acute and long-term effects of TBR NF versus a control condition in ADHD patients with varying comorbidities.

Main Methods:

• A 2-site, double-blind, randomized clinical trial involving 7-to-10-year-olds diagnosed with ADHD.
• Participants received either 38 sessions of TBR neurofeedback (n=84) or a control treatment (n=58).
• Outcomes measured were changes in parent/teacher-rated inattention from baseline to end-of-treatment and at 13-month follow-up.

Main Results:

• Seventy percent of participants had at least one comorbidity, most commonly oppositional defiant disorder (ODD) and anxiety disorders.
• Comorbidities significantly moderated the acute treatment effect: children with anxiety alone responded better to the control condition than TBR NF.
• At 13-month follow-up, children with ODD alone showed significantly better response to TBR NF compared to the control group.

Conclusions:

• TBR neurofeedback is not recommended for ADHD patients with comorbid anxiety.
• TBR neurofeedback may be beneficial for children with ADHD and comorbid ODD.
• The presence of psychiatric comorbidities is a critical factor in determining the efficacy of TBR neurofeedback for ADHD.
