Ambulatory electroencephalography (aEEG) monitoring is an EEG that is recorded at home, and it can record up to 72 hours. The aEEG increases the chance of recording an event or abnormal changes in the brain wave patterns.

What do I need to do before my test?

  • Bathe and wash your hair well.
  • Do not leave any hair products in your hair and remove any braids or hair extensions. This will facilitate comfortable placement of the electrodes. EEG wires will be attached to your head with a special glue so that the electrodes will stay attached for several days. The electrodes will be covered with gauze and a net wrap will help secure them.
  • Continue taking any prescription medications unless specifically told otherwise by your physician.
  • You should wear comfortable clothing while your ambulatory EEG is being performed. Sweatpants and a loose-fitting top with buttons down the front are suggested.

During the Ambulatory EEG test:

  • You will be instructed to fill out a log sheet for all events in question. On this sheet, please include the date, and time of day of your symptoms If any symptoms occur you will push a button on the recorder to mark the event. Do NOT hold the button down- just press and release.
  • You will not be able to shower or swim until after the equipment is removed.
  • Do not brush your hair or scratch your head during the test.
  • Do not chew gum, eat hard candy, or eat potato chips since this will generate a lot of noise and will make it difficult to detect anything.

The test set-up will require approximately 1 hour. Another appointment will be needed to return the equipment and remove the electrodes. After the EEG electrodes are removed, the EEG technologist will clean each spot on the scalp where an electrode had been applied with warm water.
