- Abstract
Self-reported effectiveness of electroencephalogram-based neurofeedback (EEG-NF) against the core symptoms of attention-deficit hyperactivity disorder (ADHD) in adolescents/adults remains unclear.
We searched PubMed, Embase, ClinicalKey, Cochrane CENTRAL, ScienceDirect, Web of Science, and ClinicalTrials.gov from inception to August 2021 for randomized clinical trials (RCTs) of EEG-NF with self-reported ADHD symptom ratings. Comparators included participants on waitlist/treatment as usual (TAU) or receiving other interventions.
Of the 279 participants (mean age = 23.48; range: 6-60) in five eligible RCTs, 183 received EEG-NF treatment. Forest plot demonstrated no difference in inattention (SMD = -0.11, 95% CI -0.39-0.18, p = 0.46), total score (SMD = -0.08, 95% CI -0.36-0.2, p = 0.56), and hyperactivity/impulsivity (SMD = 0.01, 95% CI -0.23-0.25, p = 0.91) between EEG-NF and comparison groups. Nevertheless, compared with waitlist/TAU, EEG-NF showed better improvement in inattention (SMD = -0.48, 95% CI -0.9--0.06, p = 0.03) but not hyperactivity/impulsivity (SMD = -0.03, 95% CI -0.45-0.38, p = 0.87). Follow-up 6-12 months demonstrated no difference in inattention (SMD = -0.01, 95% CI -0.41-0.38, p = 0.94), total score (SMD = 0.22, 95% CI -0.08-0.52, p = 0.15), and hyperactivity/impulsivity (SMD = -0.01, 95% CI -0.27-0.26, p = 0.96) between the two groups. Dropout rate also showed no difference (RR = 1.05, 95% CI 0.82-1.33, p = 0.72).
Our results support EEG-NF for improving inattention in adolescents/young adults, although its effectiveness against hyperactivity/impulsivity remains inconclusive.
