Abstract: According to the BIOS theory, attention deficit hyperactivity disorder (ADHD) is a disorder that transfers the power of the high-frequency bands to the low-frequency bands by changing the electrical actions generated by the brain's opposite structures. Nevertheless, studies on this disorder have often focused on the EEG walks (voltage levels) and provided no information about the status of the brain's opposites, which generate the EEG actions (voltage changes in time). In this study, we accordingly investigated the status of partial opposites in the trigonometric plots obtained from the EEG signals of children with and without ADHD, which have been recorded under the resting eyes-open and eyes-closed conditions. In other words, we first extracted a set of features from the status of partial opposites activated in the trigonometric space and the status of transitions in this plot. Then, we evaluated these features to separate children with and without ADHD by using the t-test analysis and the SVM classifiers. Generally, the outcomes of this analysis in addition to improving the separability of the ADHD children with a figure of merit (FOM) of about 72.4% detected that ADHD changes the EEG actions, so that the larger EEG actions usually occur more than the smaller EEG actions. Therefore, it seems that the proposed technique can significantly improve clinical protocols, especially in applications such as diagnostic tools, neurofeedback, and game therapy.
