Conclusions : This meta- analysis of EEG-NF in children with ADHD highlights improvement in the inattention dimension of ADHD symptoms .
Objective : We undertook a meta- analysis of published R and omized Controlled Trials ( RCT ) with semi-active control and sham-NF groups to determine whether Electroencephalogram-neurofeedback ( EEG-NF ) significantly improves the overall symptoms , inattention and hyperactivity/impulsivity dimensions for probably unblinded assessment ( parent assessment ) and probably blinded assessment ( teacher assessment ) in children with Attention Deficit Hyperactivity Disorder ( ADHD ) .
Neurofeedback in ADHD: a single-blind randomized controlled trial
Neurofeedback treatment has been demonstrated to reduce inattention , impulsivity and hyperactivity in children with attention deficit/hyperactivity disorder ( ADHD ) . However , previous studies did not adequately control confounding variables or did not employ a r and omized reinforcer-controlled design . This study addresses those method ological shortcomings by comparing the effects of the following two matched biofeedback training variants on the primary symptoms of ADHD : EEG neurofeedback ( NF ) aim ing at theta/beta ratio reduction and EMG biofeedback ( BF ) aim ing at forehead muscle relaxation . Thirty-five children with ADHD ( 26 boys , 9 girls ; 6–14 years old ) were r and omly assigned to either the therapy group ( NF ; n = 18 ) or the control group ( BF ; n = 17 ) . Treatment for both groups consisted of 30 sessions . Pre- and post-treatment assessment consisted of psychophysiological measures , behavioural rating scales completed by parents and teachers , as well as psychometric measures . Training effectively reduced theta/beta ratios and EMG levels in the NF and BF groups , respectively . Parents reported significant reductions in primary ADHD symptoms , and inattention improvements in the NF group were higher compared to the control intervention ( BF , dcorr = −.94 ) . NF training also improved attention and reaction times on the psychometric measures . 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
