What is an Ambulatory EEG?The Ambulatory EEG (AEEG) test is a powerful tool used to evaluate symptoms such as passing out, altered consciousness , confusion, episodic memory loss and seizures. 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. The period of monitoring in which you will be wearing the electrodes is typically 2 to 3 days.
What should I do to prepare for the test?Prior to the Ambulatory EEG you should do the following:
- 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.
- Eat normally and take your regularly scheduled medications as prescribed by your doctor.
- Wear a shirt that buttons or zips so it can be removed without passing over your head.
What can I expect to happen during the test?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 scalp by the EEG technologist in a painless procedure, which will take approximately 1 hour. A paste will be used to stick the electrodes to your scalp. A gauze wrap is then used to keep the scalp electrodes in place and to keep the wires together and out of your way.
Will it hurt?No.
What should I do after the AEEG test?A return visit will be scheduled to allow the EEG technologist to remove the electrodes. You will be able to resume you regular activities after this appointment.
