Facts and figures

Neurofeedback is an evidence-based technology. This means that it is validated by research that has been conducted, peer-reviewed and published by reputable scientists and scientific organizations. Neurofeedback has a more than 50-year history of research both in North America and around the world.

We have sorted through hundreds of studies to compile the following list for those who are interested in delving more deeply into the numerous applications of neurofeedback.

ADHD

ADHD

THE EFFECTS OF STIMULANT THERAPY, EEG BIOFEEDBACK, AND PARENTING STYLE ON THE PRIMARY SYMPTOMS OF ATTENTION-DEFICIT/HYPERACTIVITY DISORDER. See Study>>
Appl Psychophysiol Biofeedback. 2002 Dec;27(4):231-49.

One hundred children, ages 6-19, who were diagnosed with attention-deficit/hyperactivity disorder (ADHD), either inattentive or combined types, participated in a study examining the effects of Ritalin, EEG biofeedback, and parenting style on the primary symptoms of ADHD.

Conclusion:  The results of a Quantitative Electroencephalographic Scanning Process (QEEG-Scan; V. J. Monastra et al., 1999) revealed significant reduction in cortical slowing only in patients who had received EEG biofeedback. Behavioral measures indicated that parenting style exerted a significant moderating effect on the expression of behavioral symptoms at home but not at school.



IN-SCHOOL NEUROFEEDBACK TRAINING FOR ADHD: SUSTAINED IMPROVEMENTS FROM A RANDOMIZED CONTROL TRIAL. See Study>> 
Pediatrics. 2014 Mar;133(3):483-92.

One hundred four children were randomly assigned to receive neurofeedback, CT, or a control condition and were evaluated 6 months post-intervention.

Conclusion:  Neurofeedback participants made more prompt and greater improvements in ADHD symptoms, which were sustained at the 6-month follow-up, than did CT participants or those in the control group. This finding suggests that neurofeedback is a promising attention training treatment for children with ADHD.



SELF-REPORTED EFFICACY OF NEUROFEEDBACK TREATEMENT IN A CLINICAL RANDOMIZED CONTROLLED STUDY OF ADHD CHILDREN AND ADOLESCENTS. See Study>> 
Neuropsychiatr Dis Treat. 2014 Sep 2;10:1645-54.

Self-evaluations of neurofeedback treatment by children and adolescents with ADHD.

Conclusion:  The self-reported improvements in ADHD core symptoms and school performance shortly after treatment indicate NF treatment being promising in comparison with medication, suggesting NF as an alternative treatment for children and adolescents who do not respond to MPH, or who suffer side effects.



EFFICACY OF NEUROFEEDBACK TREATEMENT IN ADHD: THE EFFECTS ON INATTENTION, IMPULSIVITY AND HYPERACTIVITY: A META-ANALYSIS. See Study>> 
Arns, Clin EEG Neurosci. 2009 Jul;40(3):180-9.

In this study selected research on neurofeedback treatment for ADHD was collected and a meta-analysis was performed.

Conclusion:  Neurofeedback treatment for ADHD can be considered “Efficacious and Specific” (Level 5) with a large ES for inattention and impulsivity and a medium ES for hyperactivity.



DIFFERENTIAL EFFECTS OF THETA/BETA AND SMR NEUROFEEDBACK IN ADHD ON SLEEP ONSET LATENCY. See Study>> 
Front Hum Neurosci. 2014 Dec 23;8:1019.

In this study we compared adult ADHD patients (N = 19) to a control group (N = 28) and investigated if differences existed in sleep parameters such as Sleep Onset Latency (SOL), Sleep Duration (DUR) and overall reported sleep problems (PSQI) and if there is an association between sleep-parameters and ADHD symptoms.

Conclusion:  These results suggest differential effects and different working mechanisms for TBR and SMR neurofeedback in the treatment of ADHD.



IS NEUROFEEDBACK AN EFFICACIOUS TREATMENT FOR ADHD? A RANDOMISED CONTROLLED CLINICAL TRIAL. See Study>> 
J Child Psychol Psychiatry. 2009 Jul;50(7):780-9.

Evaluation of the clinical efficacy of neurofeedback in children with ADHD in a multisite randomised controlled study using a computerised attention skills training as a control condition.

Conclusion:  Superiority of the combined NF training indicates clinical efficacy of NF in children with ADHD. Future studies should further address the specificity of effects and how to optimise the benefit of NF as treatment module for ADHD.



FUNCTIONAL MAGNETIC RESONANCE IMAGING INVESTIGATION OF THE EFFECTS OF NEUROFEEDBACK TRAINING ON THE NEURAL BASES OF SELECTIVE ATTENTION AND RESPONSE INHIBITION IN CHILDREN WITH ATTENTION-DEFICIT/HYPERACTIVITY DISORDER. See Study>> 
Appl Psychophysiol Biofeedback. 2006 Mar;31(1):3-20.

Two functional magnetic resonance imaging (fMRI) experiments were undertaken to measure the effect of neurofeedback training (NFT), in AD/HD children, on the neural substrates of selective attention and response inhibition.

Conclusion:  Suggests that NFT has the capacity to functionally normalize the brain systems mediating selective attention and response inhibition in AD/HD children.



NEUROFEEDBACK IN CHILDREN WITH ADHD: SPECIFIC EVENT-RELATED POTENTIAL FINDINGS OF A RANDOMIZED CONTROLLED TRIAL. See Study>> 
Clin Neurophysiol. 2011 May;122(5):942-50

Children with ADHD either completed a NF training or a computerized attention skills training (ratio 3:2)

Conclusion:  CNV effects reflect neuronal circuits underlying resource allocation during cognitive preparation. These distinct ERP effects are closely related to a successful NF training in children with ADHD. In future studies, neurophysiological recordings could help to optimize and individualize NF training.



NEUROFEEDBACK IN ADHD: A SINGLE-BLIND RANDOMIZED CONTROLLED TRIAL. See Study>> 
Eur Child Adolesc Psychiatry. 2011 Sep;20(9):481-91.

This study addresses those methodological shortcomings by comparing the effects of the following two matched biofeedback training variants on the primary symptoms of ADHD: EEG neurofeedback (NF) aiming at theta/beta ratio reduction and EMG biofeedback (BF) aiming at forehead muscle relaxation.

Conclusion:  The results indicate that NF effectively reduced inattention symptoms on parent rating scales and reaction time in neuropsychological tests. However, regarding hyperactivity and impulsivity symptoms, the results imply that non-specific factors, such as behavioural contingencies, self-efficacy, structured learning environment and feed-forward processes, may also contribute to the positive behavioural effects induced by neurofeedback training.



NEUROFEEDBACK IN ADHD AND INSOMNIA: VIIGLANCE STABILIZATION THROUGH SLEEP SPINDLES AND CIRCADIAN NETWORKS. See Study>> 
Neurosci Biobehav Rev. 2014 Jul;44:183-94.

An overview of the history and current status of neurofeedback for the treatment of ADHD and insomnia.

Conclusion:  Clinical trials investigating new treatments in ADHD should include assessments at follow-up as their primary endpoint rather than assessments at outtake. Furthermore, an implication requiring further study is that neurofeedback could be stopped when SOI is normalized, which might result in fewer sessions.



NEUROFEEDBACK FOR THE TREATMENT OF CHILDREN AND ADOLESCENTS WITH ADHD: A RANDOMIZED AND CONTROLLED CLINICAL TRIAL USING PARENTAL REPORTS. See Study>> 
BMC Psychiatry. 2012 Aug 10;12:

A randomized and controlled clinical study to evaluate the use of neurofeedback (NF) to treat attention-deficit/hyperactivity disorder (ADHD) in children and adolescents.

Conclusion:  Neurofeedback produced a significant improvement in the core symptoms of ADHD, which was equivalent to the effects produced by MPH, based on parental reports. This supports the use of NF as an alternative therapy for children and adolescents with ADHD.



NEUROFEEDBACK AND STANDARD PHHARMACOLOGICAL INTERVENTION IN ADHD. A RANDOMIZED CONTROLLED TRIAL WITH SIX-MONTH FOLLOW-UP. See Study>> 
Biol Psychol. 2013 Sep;94(1):12-21.

A randomized controlled trial that aims to evaluate the efficacy of Neurofeedback compared to standard pharmacological intervention in the treatment of attention deficit/hyperactivity disorder (ADHD).

AUTISM

Autism

NEUROREHABILITATION OF SOCIAL DYSFUNCTIONS: A MODEL-BASED NEUROFEEDBACK APPROACH FOR LOW AND HIGH-FUNCTIONING AUTISM. See Study>>
Pineda, Front Neuroeng. 2014 Aug 7;7:29

A preliminary yet promising observations to support the hypothesis that neurofeedback training (NFT) in combination with a new behavioral intervention, TAGteach, is a viable treatment option not only for high-functioning but also for low-functioning children with ASD.

Conclusion:  There are few research studies including children on the lower end of the autism spectrum, which creates poor treatment options for this population. In this review we present TAGteach in combination with NFT as a promising alternative that may be suitable for low functioning children on the spectrum.



NEUROFEEDBACK TRAINING PRODUCES NORMALIZATION IN BEHAVIOURAL AND ELECTROPPHYSIOLOGICAL MEASURES OF HIGH-FUNCTIONING AUTISM. See Study>>

Neurofeedback training (NFT), based on operant conditioning of the electroencephalogram (EEG), has shown promise in addressing abnormalities in functional and structural connectivity.

Conclusion:  The results showed improvements in ASD subjects but not in TDs. This suggests that induction of neuroplastic changes via NFT can normalize dysfunctional mirroring networks in children with autism, but the benefits are different for TD brains.



ASSESSMENT-GUIDED NEUROFEEDBACK FOR AUTISTIC SPECTRUM DISORDER. See Study>>
Journal of Neurotherapy 11(1):5-23 · June 2007

Research reviewing the epidemiology of Autism (Medical Research Council, 2001) indicated that approximately 60 per 10,000 children (1/166) are diagnosed with Autistic Spectrum Disorder (ASD).

Conclusion:  Evidence from multiple measures has demonstrated that neurofeedback can be an effective treatment for ASD. In this population, a crucial factor in explaining improved clinical outcomes in the experimental group may be the use of assessment-guided neurofeedback to reduce cerebral hyperconnectivity.

Conclusion:  The reduction of theta power is assumed to reflect modulation of activity in the anterior cingulate cortex (ACC), which is known to be involved in social and executive dysfunctions in autism.



NEUROFEEDBACK IMPROVES EXECUTIVE FUNCTIONING IN CHILDREN WITH AUTISM SPECTRUM DISORDERS. See Study>>
Research in Autism Spectrum Disorders 3 (2009) 145-162

Neurofeedback successfully reduced children’s heightened theta/beta ratio by inhibiting theta activation and enhancing beta activation over sessions.

Conclusion:  These findings suggest a basic executive function impairment in ASD that can be alleviated through specific neurofeedback treatment. Possible neural mechanisms that may underlie neurofeedback mediated improvement in executive functioning in autistic children are discussed.



DEPRESSION AND ANXIETY

Depression/Anxiety

EFFECTS OF SALIENCE-NETWORK-NODE NEUROFEEDBACK TRAINING ON AFFECTIVE BIASES IN MAJOR DEPRESSIVE DISORDER. See Study>>
Psychiatry Res. 2016 Jan 19. pii: S0925-4927(16)30026-9.

Neural models of major depressive disorder (MDD) posit that over-response of components of the brain’s salience network (SN) to negative stimuli plays a crucial role in the pathophysiology of MDD.

Conclusion:  Our findings provide support for a neural formulation in which the SN plays a primary role in contributing to negative cognitive biases in MDD.



A CONTROLLED STUDY ON THE COGNITIVE EFFECT OF ALPHA NEUROFEEDBACK TRAINING IN PATIENTS WITH MAJOR DEPRESSIVE DISORDER. See Study>>

This study aims to investigate whether neurofeedback (NF) training can improve working memory (WM) performance in patients with major depressive disorder (MDD).

Conclusion:  A positive correlation was found for the NF group between the improvement in processing speed and the increase of beta power at both the sensor and brain source level. These results show the effectiveness of this NF protocol in improving WM performance in patients with MDD.



EFFECT OF A PSYCHONEUROTHERAPY ON BRAIN ELECTROMAGNETIC TOMOGRAPHY IN INDIVIDUALS WITH MAJOR DEPRESSIVE DISORDER. See Study>>
Psychiatry Res. 2009 Dec 30;174(3):231-9

Study to measuring the effect of a psychoneurotherapy on brain source generators of abnormal EEG activity in individuals with major depressive disorder (MDD).

Conclusion:  After treatment, only participants who successfully normalized EEG activity in cortico-limbic/paralimbic regions could be considered in clinical remission. In these regions, significant correlations were found between the percentage of change of depressive symptoms and the percentage of reduction in high-beta activity. These results suggest that the normalization of high-beta activity in cortico-limbic/paralimbic regions can be associated with a significant reduction of depressive symptoms.

PERFORMANCE AND MEMORY

Performance and Memory

NEUROFEEDBACK TRAINING WITH A MOTOR IMAGERY-BASED BCI: NEUROCOGNITIVE IMPROVEMENTS AND EEG CHANGES IN THE ELDERLY. See Study>>
Med Biol Eng Comput. 2016 Feb 23.

Neurofeedback training (NFT) has shown to be promising and useful to rehabilitate cognitive functions. Recently, brain-computer interfaces (BCIs) were used to restore brain plasticity by inducing brain activity with an NFT.

Conclusion:  Results from cognitive tests showed significant improvements (p < 0.01) in four cognitive functions after performing five NFT sessions: visuospatial, oral language, memory, and intellectual. This established evidence in the association between NFT performed by a MI-BCI and enhanced cognitive performance. Therefore, it could be a novel approach to help elderly people.



WORKING MEMORY TRAINING USING EEG NEUROFEEDBACK IN NORMAL YOUNG ADULTS. See Study>>
Biomed Mater Eng. 2014 Jan 1;24(6):3637-44.

Recent studies have shown that working memory (WM) performance can be improved by intensive and adaptive computerized training. Here, we explored the WM training effect using Electroencephalography (EEG) neurofeedback (NF) in normal young adults.

Conclusion:  Our results demonstrated that these normal young adults succeeded in improving their WM performance with EEG NF, and the pre- and post-test evaluations also indicated that WM performance increase in experimental group was significantly greater than control groups. In summary, our findings provided preliminarily evidence that WM performance can be improved through learned regulation of the EEG power ratio using EEG NF.



SENSORIMOTOR RHYTHM NEUROFEEDBACK ENHANCES GOLF PUTTING PERFORMANCE. See Study>>
J Sport Exerc Psychol. 2015 Dec;37(6):626-36.

This study investigated the effect of SMR neurofeedback training (SMR NFT) on golf putting performance.

Conclusion:  Our results showed that the SMR group performed more accurately when putting and exhibited greater SMR power than the control group after 8 intervention sessions. This study concludes that SMR NFT is effective for increasing SMR during action preparation and for enhancing golf putting performance. Moreover, greater SMR activity might be an EEG signature of improved attention processing, which induces superior putting performance.



THE EFFECT OF TRAINING DISTINCT NEUROFEEDBACK PROTOCOLS ON ASPECTS OF COGNITIVE PERFORMANCE. See Study>>
International Journal of Psychophysiology 47 (2003) 75–85

The use of neurofeedback as an operant conditioning paradigm has disclosed that participants are able to gain some control over particular aspects of their electroencephalogram (EEG).

Conclusion:  Suggests that normal healthy individuals can learn to increase a specific component of their EEG activity, and that such enhanced activity may facilitate semantic processing in a working memory task and to a lesser extent focused attention. We discuss possible mechanisms that could mediate such effects and indicate a number of directions for future research.



ECOLOGICAL VALIDITY OF NEUROFEEDBACK: MODULATION OF SLOW WAVE EEG ENHANCES MUSICAL PERFORMANCE. See Study>>
Neuroreport. 2003 Jul 1;14(9):1221-4.

Biofeedback-assisted modulation of electrocortical activity has been established to have intrinsic clinical benefits and has been shown to improve cognitive performance in healthy humans.

Conclusion:  In a pilot study, single-blind expert ratings documented improvements in musical performance in a student group that received training on attention and relaxation related neurofeedback protocols, and improvements were highly correlated with learning to progressively raise theta (5-8 Hz) over alpha (8-11 Hz) band amplitudes. These findings were replicated in a second experiment where an alpha/theta training group displayed significant performance enhancement not found with other neurofeedback training protocols or in alternative interventions, including the widely applied Alexander technique.
