The problem with neurofeedback is it is a broad term. There are many different types. Lots of snake oil and some worthwhile for specific symptoms. Dr Walker in Dallas TX has had some success but it takes weeks.

If you have $10,000 to risk, Cognitive FX | Premier Cognitive Imaging and Therapy may be worth a try. I am skeptical but...... They are in Utah by Salt Lake City.
