An electroencephalogram (EEG) is a test that measures the electrical activity in the brain, called brain waves. An EEG measures brain waves through small button electrodes that are placed on your child's scalp.
Read the patient family EEG teaching sheet.
Consider the following when preparing your child for an EEG:
- Wash your child's hair the night before. Do not put any oil, gel, or hairspray on his/her hair. If your child's hair is long, do not braid or put it up. No hair extensions please.
- To get the maximum information from this test, your child's physician will try to record EEG during wakefulness and sleep.
- Give your child his/her medications as usual. Bring a list of all the medications (dose and schedule) your child takes to the EEG Lab.
- Your child's physicians will give you instructions about when your child can eat before and after the procedure.
- On the day of the EEG, your child should not have any drinks containing caffeine, such as caffeinated sodas, coffee and tea.
Accredited EEG Lab
Our EEG lab is accredited by the EEG Laboratory Accreditation Board of ABRET (LAB-EEG), which means we perform EEGs to the highest standards.
We are the second hospital in Georgia and the eleventh pediatric hospital in the country to achieve accreditation.

The Children's Epilepsy Center (14 Images)
Thanks to generous philanthropic support, the Children's Epilepsy Center now has 13 state-of-the-art, all-digital, video-monitored bed units for epilepsy patients, making it one of the largest and busiest pediatric units in the country.
- A trained, registered neurophysiology technologist will perform the test.
- Your child will be asked to lie down on a bed or stretcher. The technologist will explain the procedure to you and your child.
- The EEG technologist measures your child's head and makes small marks on the scalp with a washable marker or pen. Each marked area is rubbed with a gritty lotion so the electrodes transmit well. Glue is put on the electrodes, which are applied to each of the marked spots on the scalp.
- The electrodes are connected to the EEG machine and the test begins. Your child will need to sit or lie as still as possible. He/she may be asked to breathe fast (hyperventilate), look at flashing lights, and try to sleep.
- The test takes about one hour, and your child is usually videotaped during the EEG. Your child's physician may order a video EEG to give more time to study the brain waves. The procedure is the same, but may last six to eight hours.
Patients must arrive 30 minutes prior to their appointment to register. If the patient is 15 or more minutes late, then the appointment may be cancelled.

What happens after the EEG?
Once the test is complete, the electrodes will be removed and the glue washed off with warm water and a washcloth. Sometimes, all the glue will not come off and you may need to wash your child's hair at home.
The technologist or nurse will give you further instructions and tell you when you and your child may leave.
Are there any risks involved with the procedure?
Experts in neurology have studied EEG for many years and report that it is a safe procedure, with no apparent risks.
Who evaluates the EEG recordings?
A neurologist will read the EEG and then talk to your child's physician about the results.
