I hear mixed things about it. Some people think its does not work because there are no double-blind placebo trials to prove it, but its really impossible to conduct such a test because you can't give someone placebo neurofeedback. Others say it really helps with hypertension, adhd, and mtbi. NASA uses it to help their pilots concentrate. It makes sense to me... People with mTBI and ADHD have QEEG's that differ from the norm of the population. Neurofeedback can train your brain to have a more normal QEEG and people say when this happens they feel better. Its worth a try... I am waiting to see if I get better with time, but I think I will eventually try it if I don't get back to feeling well every day like I used to.
