Doctors use EEGs (electroencephalograms) to see and record a person’s brain waves. Often “pictures” of the brains of people with ADHD show that a certain section does not “light up” or become as active as it is in normal brains. The treatment using this information is also called neurofeedback. People with ADHD are taught how to make these brain sections more active. After training, a patient’s behaviors –such as lack of attention and hyperactive/impulsive behavior — may improve. Too little research has been done to know for certain that EEG biofeedback works well. Also, parents should know that biofeedback treatments can be expensive.
