What is an EEG?

This test helps us find out more about the kind of seizures or events your child may be having. During the test, your child’s actions and behaviors are recorded by a camera. This is paired with an EEG recording of your child’s brain wave activity. Sometimes, movements may look like seizures, but they are not. If your child has seizures, this study will help us learn how strong they are and how often they occur. It will also help us find out what part of the brain the seizures are coming from.

This test will also help us decide if your child is having silent seizures. These are seizures that occur without any physical signs. Changes can be seen on the EEG with this type of seizure.
The test is painless. There will not be any shots or special medicines used. Small metal disks will be placed on your child’s scalp. Your child’s hair will be moved out of the way. These disks will be held in place using special glue, made just for this test.

A gel (salt jelly) will be placed in each disk. The gel allows us to pick up your child’s brainwaves. We will wrap your head and the wires with a gauze bandage to keep them secure for the day.

The time needed for an outpatient video EEG may be from 2 to 8 hours.

  • Try to arrive 15 minutes before scheduled test time.

  • You and your child will be in a large, comfortable room for the day. There will be a TV/VCR/DVD along with a Play Station for games in the room.

  • You and your child will be asked to stay in this room for as long as the test takes. You may use the restroom which is just outside the room. An adult must always be with your child.

  • Please bring any items to keep you and your child busy such as books, cross word puzzles, movies, videos, and other such things.

  • Your child’s hair must be clean for this test. Wash it the night before or in the morning. Do not apply a lot of conditioners, gels, or sprays.

  • If the test is ordered as ‘Sleep Deprived’, try to keep your child up as late as you can the night before. See the Health Facts for Sleep Deprived EEG #4207.

  • You may purchase food items from the cafeteria or you can bring your own snacks from home.

  • When the test is complete, the disks will be removed with a mineral-oil based remover. Your child’s hair will be somewhat oily when you leave. This will shampoo out. You may choose to have the disks removed with nail polish remover to avoid the problem of oily hair. This has a strong odor. We will not use it unless you ask for it.

After the Procedure

The final report on your EEG will be sent to your referring and/or primary doctor within a few days. He or she will discuss the results of the test with you and suggest treatment, if needed.
