Back in 1997, when qEEG was starting to become validated by multiple separate studies, a single article written in the Journal of Neurology made the claim that qEEG was quackery. Even thought the methodology of the article's author has since been soundly proven false, the word was already out. It is hard to un-ring that bell.

Neuros do not change their minds easily. Since qEEG is promoted by the bio-feedback industry where very few have more than a Master's degree, it is easy to discredit. Plus, the equipment to do the testing is cheap and sold by quite a few 'mom and pop' shops and just about anybody can use it, there is no financial gain by the big medical industries promoting it.
