EEG Biofeedback is a learning strategy that enables persons to alter their brain waves. When information about a person’s own brain wave characteristics is made available to him, he can learn to change them. You can think of it as exercise for the brain. An initial interview is done to obtain a description of symptoms, and to get a picture of the health history and family history. Some testing may be done as well. And the person does the first EEG training session, at which time we get a look at the EEG. This all may take about two hours. (The details may differ among the various affiliate offices. In some offices a full brain map, or quantitative EEG, is routinely obtained, which may require a separate office visit. Or more extensive testing may be done.) Subsequent training sessions last about 40 minutes to an hour, and are conducted from one to five times per week. Some improvement is generally seen within ten sessions. Once learning is consolidated, the benefit appears to be permanent in most cases.
The EEG biofeedback training is a painless, non-invasive procedure. One or more sensors are placed on the scalp, and one to each ear. The brain waves are monitored by means of an amplifier and a computer-based instrument that processes the signal and provides the proper feedback. This is displayed to the trainee by means of a video game or other video display, along with audio signals. The trainee is asked to make the video game go with his brain. As activity in a desirable frequency band increases, the video game moves faster, or some other reward is given. As activity in an adverse band increases, the video game is inhibited. Gradually, the brain responds to the cues that it is being given, and a “learning” of new brain wave patterns takes place. The new pattern is one which is closer to what is normally observed in individuals without such disabilities.
