The link above references an interesting piece on NPR about how neurofeedback can be used to treat ADD/ADHD:
Even though there are studies now showing that neurofeedback works for ADHD, all of these studies have serious limitations, researchers say. So the approach remains promising but unproved, says David Rabiner, a researcher at Duke University who writes a newsletter about treatments for ADHD...
A team at The Ohio State University has nearly completed a pilot study of neurofeedback for ADHD that was funded by the National Institute of Mental Health.
The team had hoped to announce results last week at a scientific meeting in New York, but Gene Arnold, one of the scientists in charge of the study, says they had to delay that announcement because "we weren't able to get the results analyzed in time," he says.
Learning Breakthrough and the vestibular-cerebellar training approach to ADHD remediation more generally have been considered by the research team at Ohio State University as well. Our interest in the topic stems from the substantial neurofeedback aspect to the Learning Breakthrough Program...as the repetitive nature of LBP's balance exercises themselves generate what the user in this article calls "constant feedback during a session" through constant motor control monitoring, planning, executive function modulation, and hemispheric integration all in one system. There is much hope that as this research progresses and the pilot study information is collated that LBP will be tested along side on neurofeedback techniques and a control group.
