What is an EEG?

An EEG (electroencephalogram) is a procedure performed to evaluate the brain waves.  Normal brain waves have a particular rhythm and shape. Abnormal brain waves can suggest an underlying seizure disorder or other neurological conditions.  The procedure is performed in the office by neurodiagnostic technicians.  The brain waves are interpreted by neurologists. A routine EEG takes approximately one hour to complete.

Will it hurt?

No.

What should I do to prepare for the test?

Prior to the EEG you should do the following:

• Wash your hair the night before using only shampoo and water.  Do not use styling aids such as hair gels, mousse, hairspray or oils of any kind. These products can interfere with the electrodes and limit the usefulness of the test.
• Eat normally and take your regularly scheduled medications as prescribed by your doctor.

What can I expect to happen during the test?

You will be given a time and location to report for application of the electrodes. During this time the electrodes will be placed on your head and the recording of the brain activity will start. The electrodes used in this test are small metal disks placed on the scalp by the EEG technologist in a painless procedure, which will take approximately 15 minutes. A paste will be used to stick the electrodes to your scalp. A gauze wrap is then used to keep the scalp electrodes in place and to keep the wires together and out of your way.

What should I do after the EEG?

A return visit will be scheduled to allow us to remove the electrodes. You will be able to resume your regular activities after this appointment.
