What happens during an EEG test?
Small metal disks (electrodes) are secured to certain areas of your scalp with an adhesive jelly. The electrodes are connected to a machine which records the electrical activity and produces a graphic record. To measure changes of electrical activity on the brain, you may be asked to perform a variety of simple functions, such as rapid breathing, opening and closing your eyes, or relaxing to the point of falling asleep. The total test takes approximately 90 minutes. When will the results of my EEG test be available? The results are typically available within three to five days. These results will be sent to your personal physician, who will make a diagnosis based upon the neurologist’s interpretation.
