Neurofeedback (NF) is a form of cerebral biofeedback in which the patient receives real-time feedback (visual or auditory) on brain signals, typically via electroencephalography (EEG). The goal is to learn self-regulation of specific cortical activity patterns, such as the theta/beta ratio, sensorimotor rhythm (SMR), or slow cortical potentials (SCP). It has been proposed as a treatment for Attention-Deficit/Hyperactivity Disorder (ADHD), but the key clinical question is not simply 'does it work?', but rather 'does it work when assessed with methodological rigor?'.
Key Findings from the 2025 Evidence Base
A meta-analysis published in JAMA Psychiatry by the EAGG consortium concludes that randomized controlled trials with 'probably blinded' outcomes — i.e., where the rater is unaware of treatment allocation — do not support EEG neurofeedback as an independent treatment for core ADHD symptoms (inattention and hyperactivity-impulsivity). When parents or therapists aware of treatment allocation report outcomes, effect sizes appear larger, indicating significant expectancy bias.
Does This Mean Neurofeedback Is Entirely Ineffective?
Not necessarily. It means that, on average and using robust outcome measures, there is no clear signal of clinically meaningful benefit as monotherapy. However, there may be heterogeneity: patient subgroups, specific protocols (theta/beta, SCP, fNIRS-based neurofeedback), or partial improvements in cognitive variables that have not yet translated consistently into large clinical changes. Recent studies on 'portable' formats and novel approaches exist, but the core evidence base remains under active debate.
Comparative Positioning: Where Neurofeedback Fits Among Alternatives
- Pharmacotherapy (stimulants) — Evidencia: High. Ventajas: Rapid onset, larger effect size. Limitaciones: Adverse effects, adherence challenges, stigma
- Parent behavioural training — Evidencia: Moderate-high. Ventajas: Scalable, improves family context. Limitaciones: Requires sustained family engagement
- EEG Neurofeedback — Evidencia: Mixed; limited in blinded outcomes. Ventajas: Good acceptability, skill-based approach. Limitaciones: High cost/time, uncertain effect, expectancy bias
- Physical exercise — Evidencia: Growing as adjunctive. Ventajas: Global health benefits, self-regulation. Limitaciones: Variable dosing and adherence
For Whom Might Neurofeedback Be Reasonable?
Patients or families who decline or cannot tolerate pharmacotherapy, yet accept a structured programme with realistic goals. Also as an adjunctive intervention within a multimodal treatment plan (behavioural + lifestyle + school-based + exercise). Profiles targeting specific skills such as sustained attention or emotional self-regulation, always with objective outcome metrics.
Not appropriate when seeking global improvement without predefined metrics, when framed as the sole 'anti-medication' alternative with strong claims, or when adherence to 20–40 sessions and acceptance of reassessment/discontinuation are unlikely.
The GNeuro Differentiator
A 'clinic-first' model: rigorous candidate selection, predefined objective metrics, early reassessment (at 10–12 sessions) and data-driven decision-making. We integrate assessment with quantitative EEG, objective algometry, and our 4D Biofeedback systems to deliver a personalised and evidence-based clinical pathway.
