WHAT YOU NEED TO KNOW: What do I need to know about an electroencephalogram (EEG)? An EEG is a test that measures the electrical activity in your child's brain. It can help healthcare providers decide what treatments your child needs. An EEG can help diagnose or monitor any of the following: - Seizures
- Sleep disorders
- Brain infection, disease, or injury
- Brain activity during brain surgery or a coma
- Brain activity before a medical procedure or surgery
How should I prepare my child for an EEG? Your child's healthcare provider will talk to you about how to prepare your child for an EEG. He will tell you what medicines to give your child or not give on the day of the test. Do not let your child drink or eat foods with caffeine on the day of the test. Do not put oils or lotions on your child's scalp or hair for 24 hours before the test. This includes conditioner, hair spray, hair cream, or hair gel. What will happen during an EEG? - Your child will not feel pain during the test. You may be able to stay with your child during the test or you may need to leave the room. Healthcare providers will ask your child to lie still and not talk during the test. A healthcare provider will put gel or cream on your child's scalp. He will place small discs in different places on your child's head. The discs will be connected to wires and a monitor. The monitor will record the electrical activity of your child's brain.
- During the test your child may be asked to change how fast he or she breathes. Your child may also be asked to look at pictures or a flashing light. The healthcare provider may make loud noises.
- Bright lights or loud noises may cause your child to have a seizure during the test. Healthcare providers may give your child medicine to control or stop the seizure. They will also help protect your child from injury.
- Your child may be given medicine to help him or her sleep during the test. Your child may also be videotaped during the test. The videotape will help healthcare providers watch for signs of a seizure.
