Impact of EEG biofeedback on event-related potentials (ERPs) in attention-deficit hyperactivity (ADHD) children. Introduction: ADHD is one of the most widely spread condition of school aged children affecting 5% of children of this age.The core clinical signs of ADHD are inattention, restlessness and impulsivity. According to various authors direct measures of attention are of two types: 1. Recording the alpha rhythm on the EEG and event-related potentials (ERP); 2. Tests of reaction time, continuous performance tests, paired associated learning, and tests of memorization; The second one is evidence-based. As for the first one it is known that ERPs especially of those with later response reflect the process of mental effortfullness to select the appropriate behavior and accomplish decision making during the action of target stimulus. Thus selection of action as well as decision making is the most important points affected in ADHD children. Besides in recent years EEG biofeedback (Neurofeedback) have become the evidence-based in the treatment of ADHD. Unfortunately the effectiveness of this approach on ERPs parameters is still unknown. Thus we aimed to study the changes of ERPs after neurofeedback therapy. Methods: We have examined 16 children with ADHD before- and after 3- sessions of neurofeedback therapy and 23 without treatment. Results: We have observed statistically significant improvement of parameters of later response like P300 in treated children compared with untreated ones whereas the treatment was non effective for earlier components of ERPs. Conclusions: Neurofeedback can affect on the process of selection of action and decision making by means of changing of P300 parameters in ADHDchildren.
