People commonly asked about the difference between biofeedback and neurofeedback. They may have heard both words but the difference is a mystery.
Simply speaking, biofeedback an umbrella term for all body-focused feedback training modalities-- including neurofeedback. It's much like the umbrella term "doctor." All psychologists are doctors, but not all doctors are psychologists-- some are physicians and some are art historians!
Neurofeedback focuses solely on the brain and is sometimes referred to as EEG Biofeedback. It's often used for conditions such as epilepsy, traumatic brain injury, etc. Other forms of biofeedback focus on other physical functions such as respiration, body temperature, heart-rate variability, etc. These other modalities may be used for anxiety, PTSD, depression, chronic pain, IBS, etc.
