Changes in EEG Spectrograms, Event-Related Potentials and Event-Related Desynchronization Induced by Relative Beta Training in ADHD Children

Abstract

Background. During the last three decades EEG-based biofeedback (neurofeedback) was used as an alternative treatment for reducing symptoms of ADHD. The goal of this study was to objectively assess the efficacy of biofeedback training by comparing spectrograms, ERPs and ERDs, measured before and after 20 sessions of neurotherapy in a group of ADHD children.
