AMBULATORY EEG (electroencephalogram)

What should I expect?

  • Application of electrodes takes about one hour
  • Small electrodes will be pasted to your scalp to detect brain electrical activity
  • The electrodes are connected to a small computer that you will take home
  • The lightweight computer is worn in a shoulder pouch
  • A tight gauze wrap is used to keep electrodes and wires in place while you are at home
  • You may bring a hat or scarf to wear over the electrode wrap

When will I receive results?

  • Results are available in 1 week
  • If your neurologist has requested an in-office visit for results review, please ensure that it is scheduled no earlier than 1 week after the test is performed


How do I handle the equipment?

  • Do not under any circumstances take a shower while the test is in progress. You may wash from neck down with a washcloth. Be careful not to get any water into the computer.
  • You must change the batteries located inside the computer every 24 hours to ensure the completion of your test. The technologist will explain and provide you with ample supply of the batteries (x2 for each day of your test).
  • No excessive chewing during the test (gum, potato chips, etc.)
  • No tampering of any kind with the computer or electrodes.
  • Please complete the EVENT CALENDAR to report any episodes. Please be specific about the date and time of the event along with a brief description of what occurred so we may correlate with the reading.
  • The technologist will discuss the Event button. This is a small button on the side of the computer that should be pressed in the event of an episode. By pressing this button the physician reviewing the study will know exactly when the episode occurred and will be able to see what changes occurred on the EEG.
