The EMU is part of the comprehensive epilepsy program. 

What is a Video Electroencephalography (VEEG)?

Video EEG uses special equipment and a camera to record your child’s brain waves and behavior at the same time. The purpose of video EEG is to monitor your child’s brain waves and behavior during the events (seizures or episodes) that your child is having. If your child is having different types of events, we like to record examples of each.

 The results of the test will help the doctor:

  • Learn whether your child is having epileptic seizures or other episodes

  • Find out the type(s) of seizures and where they begin in the brain

  • Decide the best way to manage your child’s condition

A doctor specialized in the management of epilepsy will decide how long your child needs to be monitored. This can be from several hours to days, depending on how many seizures or episodes your child is having.

Before the Video EEG:

  • Make plans so that one parent or another caregiver can stay with your child at the hospital for the entire length of the test. We encourage you to make arrangements for someone else to care for your other children. Brothers, sisters, or friends may plan short visits.

  • Wash your child’s hair. The hair must be clean and free of any hair products such as conditioner, hair spray, gel, wax, oil or mousse.

  • Your child can eat, drink, and take any prescribed medications before the VEEG, unless your doctor has given you other instructions.

  • Do not let your child drink or eat anything that contains caffeine. This means no cola or soda pop, energy drinks, hot chocolate, tea or coffee, or chocolate.
