Patient Information For Ambulatory Video
EEG Monitoring

Welcome! Your doctor has requested that a test be performed called ambulatory video EEG monitoring (AVEEG). This test is a powerful tool in the assessment and treatment of various conditions. During this test, small electrodes placed on your scalp will detect electrical activity from your brain. This information will be stored in a small computer that you will be able to carry around with you. During monitoring a small video camera will record your daily activity this will help correlate any reported clinical or behavioral changes simultaneously with brain activity. The period of monitoring in which you will be wearing the electrodes ranges between 2 to 4 days.

The test is not harmful and is painless. If you have any questions at any time feel free to call our physicians or technicians. They are available 24 hours- seven days a week to answer any of your questions.

This handout covers various aspects of the ambulatory EEG test. Please review this information. It is important that you understand this material so that the most accurate and beneficial results will be obtained.

Preparing for the Ambulatory EEG monitoring test

Prior to the ambulatory EEG test you should:

  1. Wash your hair the night before using only shampoo and water. Do not use styling aids such as hair gels, mousse, hairspray or oils of any kind. These products can interfere with the electrodes and limit the usefulness of the test.
  2. Eat normally and take your regularly scheduled medications as prescribed by your doctor.
  3. Wear shirts that button or zipper so they can be removed without passing over your head. Once the electrodes are in place it will be difficult to take off your shirt over your head if you cannot unbutton or unzip them.

Electrode Application

You will be given a time and location to report for application of the electrodes. During this time the electrodes will be placed on your head and the recording of the brain activity will start. The electrodes used in this test are small metal disks placed on the skin by the EEG technologist in a simple procedure, which should take approximately 1 hour. A paste or glue will be used to stick the electrodes to your scalp. A gauze wrap is then used to keep the electrodes and wires together out of you way. Please note the following:

  1. Children having the test should have a parent or guardian with them throughout the entire electrode application procedure.
  2. If you do not speak English it would be helpful to arrange for a translator to accompany you to the test.
  3. You may bring with you a hat or scarf to wear over the head wrap once the electrode application has been completed.
