Commonly proven abnormalities in the structure and functioning of the prefrontal cortex (PFC) are related to cognitive deficits in children with ADHD. The purpose of the randomized controlled study was to assess the efficacy of intervention using hemoencephalographic biofeedback (HEG BFB) in PFC in ADHD and neurotypical children. The final cohort consisted of 120 children aged 9–15 years, including 60 children with ADHD. The individuals were randomized in 10 HEG BFB or physical activity (PA) training sessions. Children with ADHD exhibited lower cognitive capacity in terms of vigilance, visual search, multitasking, inhibitory control and working memory compared to neurotypical children. The performance of children with ADHD and neurotypical children in cognitive functions improved under the influence of HEG BFB (the PA training did not have a statistically significant impact on the results). The important gain predictors in HEG BFB involved: intrinsic motivation, internal locus of control and positive mood.
