The QEEG is done by placing a cap that looks like a swimmer's cap onto the head. There are somewhere in the neighborhood of 25-30 electrodes inserted onto the cap. During the test, the client is asked to do a series of tasks such as read, arithmetic, relax with eyes closed, recall general knowledge, etc... This is then analyzed and compared against a normal population.

It is much more sensitive than a regular EEG that hospitals use. The standard EEG is basically looking for seizure activity and usually nothing more. A person who doesn't experience seizure activity will have a normal EEG; however, if they have had a concussion, it will show up on the QEEG.
