Neurofeedback (NF) has been introduced to treat ADHD recently and is able to improve the attention level and alleviate the hyperactivity symptoms [7–12]. The process provides a mechanism by which the patient can normalize the cortical activity profile through decreasing slow wave activity and increasing fast wave activity. It is expected that compensation of the dysfunctional electroencephalogram (EEG) enhances concentration and attention and increases the arousal level [13–17]. In fact, patients will learn how to enhance the desirable EEG frequencies associated with relaxed attention and how to reduce the undesirable frequencies which are associated with under- or overarousal .
