Are there harmful side-effects from neurofeedback?
As a technique, neurofeedback is generally benign because it is a learning and conditioning technique. It is similar to physical fitness training in which repetition and reinforcement are used to gently and gradually improve a particular function. But just as you can have a poor physical-fitness trainer, you can have a poor neurofeedback provider, so people should seek a well-trained and reputable provider. We recommend a registered mental-health provider who has both training and clinical credentials.
