Annotation: Neurofeedback – train your brain to train behaviour / Hartmut HEINRICH in Journal of Child Psychology and Psychiatry, 48-1 (January 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-1 (January 2007) . - p.3–16 Titre : Annotation: Neurofeedback – train your brain to train behaviour Type de document : Texte imprimé et/ou numérique Auteurs : Hartmut HEINRICH, Auteur ; Holger GEVENSLEBEN, Auteur ; Ute STREHL, Auteur Année de publication : 2007 Article en page(s) : p.3–16 Langues : Anglais (eng) Mots-clés : Neurofeedback electroencephalogram-(EEG) frequency-bands slow-cortical-potentials-(SCPs) attention-deficit-hyperactivity-disorder-(ADHD) epilepsy self-regulation Index. décimale : PER Périodiques Résumé : Neurofeedback (NF) is a form of behavioural training aimed at developing skills for self-regulation of brain activity. Within the past decade, several NF studies have been published that tend to overcome the methodological shortcomings of earlier studies. This annotation describes the methodical basis of NF and reviews the evidence base for its clinical efficacy and effectiveness in neuropsychiatric disorders. Methods: In NF training, self-regulation of specific aspects of electrical brain activity is acquired by means of immediate feedback and positive reinforcement. In frequency training, activity in different EEG frequency bands has to be decreased or increased. Training of slow cortical potentials (SCPs) addresses the regulation of cortical excitability. Results: NF studies revealed paradigm-specific effects on, e.g., attention and memory processes and performance improvements in real-life conditions, in healthy subjects as well as in patients. In several studies it was shown that children with attention-deficit hyperactivity disorder (ADHD) improved behavioural and cognitive variables after frequency (e.g., theta/beta) training or SCP training. Neurophysiological effects could also be measured. However, specific and unspecific training effects could not be disentangled in these studies. For drug-resistant patients with epilepsy, significant and long-lasting decreases of seizure frequency and intensity through SCP training were documented in a series of studies. For other child psychiatric disorders (e.g., tic disorders, anxiety, and autism) only preliminary investigations are available. Conclusions: There is growing evidence for NF as a valuable treatment module in neuropsychiatric disorders. Further, controlled studies are necessary to establish clinical efficacy and effectiveness and to learn more about the mechanisms underlying successful training.

Is neurofeedback an efficacious treatment for ADHD? A randomised controlled clinical trial / Holger GEVENSLEBEN in Journal of Child Psychology and Psychiatry, 50-7 (July 2009)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 50-7 (July 2009) . - p.780-789 Titre : Is neurofeedback an efficacious treatment for ADHD? A randomised controlled clinical trial Type de document : Texte imprimé et/ou numérique Auteurs : Holger GEVENSLEBEN, Auteur ; Aribert ROTHENBERGER, Auteur ; Petra STUDER, Auteur ; Oliver KRATZ, Auteur ; Dieter SCHLAMP, Auteur ; Claudia VOGEL, Auteur ; Birgit HOLL, Auteur ; Hartmut HEINRICH, Auteur ; Björn ALBRECHT, Auteur ; Gunther H. MOLL, Auteur Année de publication : 2009 Article en page(s) : p.780-789 Langues : Anglais (eng) Mots-clés : Neurofeedback attention-deficit/hyperactivity-disorder-(ADHD) slow-corticalpotentials-(SCPs) theta/beta-training randomised-controlled-trial-(RCT) EEG Index. décimale : PER Périodiques Résumé : Background: For children with attention deficit/hyperactivity disorder (ADHD), a reduction of inattention, impulsivity and hyperactivity by neurofeedback (NF) has been reported in several studies. But so far, unspecific training effects have not been adequately controlled for and/or studies do not provide sufficient statistical power. To overcome these methodological shortcomings we evaluated 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. Methods: 102 children with ADHD, aged 8 to 12 years, participated in the study. Children performed either 36 sessions of NF training or a computerised attention skills training within two blocks of about four weeks each (randomised group assignment). The combined NF treatment consisted of one block of theta/beta training and one block of slow cortical potential (SCP) training. Pre-training, intermediate and post-training assessment encompassed several behaviour rating scales (e.g., the German ADHD rating scale, FBB-HKS) completed by parents and teachers. Evaluation ('placebo') scales were applied to control for parental expectations and satisfaction with the treatment. Results: For parent and teacher ratings, improvements in the NF group were superior to those of the control group. For the parent-rated FBB-HKS total score (primary outcome measure), the effect size was .60. Comparable effects were obtained for the two NF protocols (theta/beta training, SCP training). Parental attitude towards the treatment did not differ between NF and control group. Conclusions: 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.
