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.
