EEG (Electroencephalogram)

An electroencephalogram (EEG) is a painless procedure that uses small, flat metal discs (electrodes) attached to your scalp to detect electrical activity in your brain. Your brain cells communicate via electrical impulses and are active all the time, even when you’re asleep. This activity shows up as wavy lines on an EEG recording. An EEG is one of the main diagnostic tests for epilepsy. An EEG may also play a role in diagnosing other brain disorders. This procedure is painless and takes approximately 1 hour. Wash your hair the night before or the day of the test, but don’t use any conditioners, hair creams, sprays, or styling gels. Avoid anything with caffeine six hours before the test. Take your usual medications unless instructed otherwise.

The technician will measure your head and mark your scalp with a type of pencil to indicate where to attach the electrodes. Those spots on your scalp may be scrubbed with a gritty cream to improve the quality of the recording. The technician attaches flat metal discs (electrodes) to your scalp using a special adhesive. The electrodes are connected to wires to an instrument that amplifies — makes bigger — the brain waves and records them on computer equipment. Some people wear an elastic cap fitted with electrodes, instead of having the adhesive applied to their scalps. You relax in a comfortable position with your eyes closed during the test. At various times, the technician may ask you to open and close your eyes, perform a few simple calculations, read a paragraph, look at a picture, breathe deeply (hyperventilate) for a few minutes, or look at a flashing light. Wear comfortable clothes. The procedure takes approximately 45 minutes.
