Dr. Amanda has been using Neurofeedback since 1994, and has reached the point where she and our staff have very high expectations for training. When such success does not occur, or if the gains cannot hold, then there is usually a reason for that which needs to be addressed.
Neurofeedback ought to work with everybody. That is to say, nearly everyone should make gains that their parents or they themselves judge to be worthwhile. Our brains are made for learning and skill-acquisition.
For most people the actual outcome exceeds the prior expectations. What sometimes appears nearly miraculous is really nothing more than the incredible capacity of our brains to acquire or recover function when given a chance.
That said, there are some few situations in which improvements prove elusive. Only training can tell, and the effort is generally worthwhile.
