EEG Patient Instructions

An EEG, (sometimes called a brain wave test), records the electrical activity of the brain. Sensitive monitoring equipment records the brain's activity through electrodes placed on a patient's scalp. The test is done with the patient lying down and is painless. The EEG usually takes about 90 minutes.


1. Go to the main hospital entrance. Report to the admitting office in the hospital lobby fifteen minutes before your appointment time. They will process your paperwork and let the technologist know you have arrived.

2. Your scalp must be clean. Wash your hair either the night before, or the morning of the test. Do not use hairspray, gels, etc.

3. Bring a list of all medications you are taking.

4. Take medication as usual, UNLESS your physician instructed you otherwise.

5. Eat a normal breakfast or lunch.

6. Wear loose, comfortable clothing - you will be lying down.
