EEG Biofeedback Treatment of ADD

Literature searches dating back to 1968 were conducted through Psychlit and Medline services to review the scientific literature on EEG biofeedback treatment of ADD. While anecdotal and case reports cite promising evidence, methodological problems coupled with a paucity of research precludes any definitive conclusions as to the efficacy of enhanced alpha and hemisphere-specific EEG biofeedback training. One of the more promising EEG biofeedback treatment paradigms involves theta/beta training. Studies have reported that academic, intellectual, and behavioral gains have been attained with this approach. Significant behavioral and cognitive changes have also been reported following SMR training. However, research into these treatment approaches has also been marred by methodological inadequacies and lack of sufficient follow-up studies. A number of recommendations for future research into this treatment approach are made.
