Neurofeedback is a type of biofeedback that uses real-time displays of brain activity, commonly EEG readings, to teach patients to self-regulate their brain function. It works by translating brain waves into visual or auditory feedback to help improve certain brain functions like attention, memory, or relaxation. Research shows neurofeedback can help treat conditions like ADHD, anxiety, depression, and more, as it allows patients to learn to consciously control their brain activity through repetitive neurofeedback training sessions over time.
