An Ambulatory EEG (Amb EEG) is a safe, painless test which will record the electrical activity produced by your brain. An Amb EEG uses a digital recording system to record brain activity for 24-72 hours while you go about your daily routine.

Before the test, recording electrodes will be attached to your scalp with an adhesive paste or air-dried adhesive. These will be covered with gauze and a net will help secure them. You may wish to bring a scarf or loose fitting hat to cover this wrapping while going home. You must not get the electrodes or recorder wet; therefore, you will not be able to shower or swim until the equipment is removed.

You should not scratch your head during the test. You also should not chew gum while the test is running.

You will be keeping a diary of things that you do and symptoms you experience during the test. If any symptoms occur you will push a button to note the recording.

It usually takes about an hour and a half to apply the electrodes and set up the equipment. A return appointment will be needed to remove the equipment. After the recorder and electrodes are removed the technologist will remove all of the adhesive from your scalp.

Preparation for the test:

  • Shampoo your hair the night before and do not use hair products such as hairspray or styling cream.
  • Please remove all hairpieces prior to your appointment and do not fix your hair in tight braids or cornrows.
  • Continue taking any prescription medications unless specifically told otherwise by your physician.
  • Please wear a button-down or zip-front shirt since you will not be able to pull anything over your head once the electrodes are applied.

After the test you will be able to return to your normal activities immediately.
