Neurofeedback

There is a company coming to the company I work for next week offering a lecture of neurofeedback, and how it can work as a “alternate solution to Attention Deficit”. Now, any time I hear the words “alternate solution” I think scam. Is there any medical basis to this form of treatment? And, by medical basis, I mean something along the lines of New England Journal of Medicine, and NOT something like Tapping in to Your Inner Chakra.
