Neurons communicate with each other through electrochemical signals which can be measured as wave-like patterns. The brain typically uses cues from the environment to regulate these brainwave patterns. Yet overly dominant or other dysfunctional patterns may produce brainwave dysregulation and accompanying behavioral problems. Brainwave dysregulation is detected through indications of abnormal brainwave ratios as measured by EEG equipment. Neurofeedback is a form of biofeedback that allows individuals to change deregulated brainwave rhythms (biofeedback is a type of alternative medicine that trains patients to regulate internal processes using operant conditioning). Neurofeedback has proven to be an effective treatment for those with ADHD. ADHD is one of the most commonly diagnosed disorders among younger populations. Individuals with ADHD are often in a state of under-arousal and must use hyperactive movement to keep up with events in their surroundings (which may be in part due to brainwave dysregulation). In comparison to other treatments, neurofeedback can be remarkably beneficial to individuals with brainwave dysregulation while causing few or no side-effects.
