Neurofeedback is a kind of biofeedback, which teaches self-control of brain functions to subjects by measuring brain waves and providing a feedback signal.
Neurofeedback usually provides audio and or video feedback. Positive or negative feedback is produced for desirable or undesirable brain activities, respectively.
Clinical applications of neurofeedback are recommended for the treatment of attention deficit hyperactivity disorder, anxiety, depression, epilepsy, insomnia, drug addiction, schizophrenia, learning disabilities, dyslexia and dyscalculia, autistic spectrum disorders and so on as well as other applications such as pain management, and the improvement of musical and athletic performance. There are various neurofeedback treatment protocols i.e. alpha, beta, alpha/theta, delta, gamma, and theta that need to be adapted to the diagnosis and treatment goals.
To date, many studies have shown that neurofeedback therapy is an effective, non-invasive, very efficient complementary treatment of many brain dysfunctions.
