Despite therapeutic advantages of NF for patients with ADHD [10, 11, 19], the results of various studies are not conclusive. The reason for dissimilar results of available reports might be the different treatment techniques or protocols used for this purpose. In other words, since NF is almost a new treatment approach, a variety of treatment protocols is being examined. Different variations over different bands of cortical activity in various parts of the cortex have been applied, and each one has been accompanied by different clinical efficiencies. The most common treatment protocol for improving various symptoms of ADHD involves suppressing theta wave and enhancing beta wave . Alpha activity might be an interesting target of treatment as it is associated with different types of cognitive processes, memory performance, perceptual performance, and intelligence. Klimesch et al.  and Escolano et al.  report effectiveness of upper alpha power in improving cognitive performance in ADHD. However results are not conclusive about the best protocol for ADHD. Increased alpha reference power is associated with large event-related desynchronization, better memory, and perceptual performance [23, 24]. High-frequency alpha band would improve the memory function in patients with ADHD  and previous reports suggest targeting theta and alpha activity in NF protocols .
