Given that the training was frequently enough for a sufficiently long duration, the results are virtually permanent. Clinical research data pertaining to three-year and 10-year follow-up demonstrate the lasting effects of neurofeedback. It should be noted that the brain changes/ adapts to our environment, allowing us to perform and feel the best way possible in that environment. Given that our environment remains relatively stable, predictable, and pleasant, the changes achieved through neurofeedback will remain. Some clients desire to return for an occasional “tune-up” session, but this is usually not necessary.
