Ambulatory EEG (24, 48 or 72 hours)

An ambulatory EEG records brain activity for a period of 24, 48 or 72 hours using a small recorder that is worn around the waist. In addition to the appointment to set up your AEEG, an appointment is required every 24 hours until the recording is complete to make sure the electrodes remain in place.

This service is available at Royal Oak and Troy.

What to Expect

A technologist applies the electrodes with a sticky, glue-like substance. You will be asked to keep a diary to record any routine activities such as reading, exercising, eating, sleeping or crying (for children), to correlate with any abnormal activity during the time period for which you are recording.

At your next appointment (24 hours), the electrodes will be removed or you will be re-prepped for additional monitoring. You can participate in your routine activities during the day, however, you should refrain from activities or exercise that may disrupt electrode placement.
