What is an EEG?

An electroencephalogram (EEG) is a test used to record the various brain wave patterns caused by the electrical activity of the brain. Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems. Your doctor will review your child’s test results with you in your follow up appointment.

A technician will:

  • Measure your child’s head

  • Prep the area with a mild cleanser

  • Apply small metal discs with thin wires (electrodes) on the scalp

  • Once the leads are applied, a head wrap will help to keep them on

  • These electrodes will then send signals to a computer to record the results

The Procedure - Preparing Your Child

You will receive an email with the Preparation Instructions and it’s important to follow all instructions the night before the procedure.

Please wash their hair before their appointment - no gels or oils.

Sleep Deprivation Before Your Child’s Test

  • 5 years and older should have no more than 4 hours of sleep. A good time frame for sleep would be midnight-4:00 a.m.

  • 2 - 4 years old should go to sleep 2 hours later than usual and wake up 2 hours earlier than usual.

  • 6 - 23 months should wake up 2 hours earlier than usual.

  • Newborns - 5 months old please try to arrange their nap to fall during their test time.

Your child will be asked to lie on a bed (or can be held by a parent) during the test. You can help prepare your child by explaining that it won’t hurt. Still, having electrodes pasted to the scalp can be a little stressful for kids, as can lying still during the test. You can describe the room and the equipment that will be used, and reassure your child that you’ll be right there for support.

Frequently Asked Questions

 

What is the Difference Between A Routine and an Ambulatory EEG?

A Routine EEG is done in our office and typically is scheduled as a 2 hour procedure. That includes the set up and clean up, and a 1 hour recording. An Ambulatory EEG is when your child takes the recording home with you for anywhere between 24 - 72 hours.

Does My Child Need to Sleep During the Test?

A sleep recording makes for a more complete test. If your child does not sleep your doctor will review the Awake only recording and decide if they need additional information.

Should My Child Still Take Their Medication?

Your child should take their medication as prescribed except for stimulants like ADHD and ADD medication.
