There is no one size fits all. The amount of sessions required varies depending on your individual goals. NeurOptimal® training is a learning process and with each progressive session, your brain learns a little more about itself. How quickly you start to notice changes depends on how quickly the brain is learning from the information it is receiving. On average, most people will start to notice changes or shifts within 6-10 sessions. That may be enough sessions or if you are dealing with more complex issues, several sessions may be required. In the end, it is up to you because it is your brain that is doing the training and it knows what it needs. Once your brain learns something, it does not forget, so if you need to take a break from sessions, you can pick back up where you left off. If you experience a challenging time in your life, a few booster sessions may be required to remind the brain what it has learned and get back to functioning at its best.
