We highly recommend you consult your neurologist with questions regarding EEG services. We are also available to discuss EEG services with you at any time. To reach a member of the clinical services team, call us at (855) 522-7233, Option 5.
What is a Routine EEG?
This is a 20-30-minute assessment of brainwave activity and may or may not include video. The routine EEG includes traditional activation procedures such as hyperventilation and photic stimulation designed to reveal potential epileptic and non-epileptic abnormalities.
What is an Ambulatory Video-EEG?
Video-EEG is a recording of brainwave activity that is performed simultaneous with video recording of the patient’s clinical activities. Video-EEG is typically performed for a minimum of several hours and more typically for 24 to 72 hours or more. This is an ideal solution to capture the changes in brainwave activity that occur at the time of a patient’s seizures. This can also capture other episode types – detecting seizures that the patient may not be aware of. Historically, video-EEG was used exclusively in a hospital setting. Major improvements in computer technology now permit this test to be performed in the patient’s home. This advancement offers many advantages including the ability to capture episodes in a natural setting as well as comfort and convenience for the patient.
Ambulatory Video-EEG Specifics.
- This test set-up will require approximately 1-1.5 hours.
- Hair needs to be clean and dry for the test.
- Prior to test, do not use hair products such as conditioner, gel, or hairspray.
- Avoid weaves or braids (to allow easy access to your scalp when placing electrodes)
- Wear a shirt/blouse with a button or zip front.
- At the time of the hook-up process, the technologist will review equipment handling and specific instructions about your equipment.
What should I write down during the recording?
Unless otherwise instructed by your physician, please continue to take all your normally prescribed medications. Medications, including the time they were taken, should be included on the patient log sheet. Press the event button during or immediately after you experience any symptom that led your doctor to order the test. If you are running late in pressing the button, it is still better to press the button as soon as you can than not at all. You will be instructed to fill out a Log Sheet for all events in question. Include each date and time the button was pressed, noting if it was pressed late/after the episode occurred, giving a description on the event. Please describe your symptoms including how you felt and what you were doing at the time of the event. It can be helpful to have a friend or loved one write down what they observed if they are with you during the time of an event. You and/or a friend or loved one can use the camera to narrate any feeling or experience during the event.
Please remember to bring the Log Sheet and equipment to your scheduled EEG removal appointment.
Is there anything I should avoid during the Ambulatory EEG Test?
The Ambulatory EEG test gives your physician the ability to monitor your brain activity during the course of a regular day. While it is best to continue your daily routine, there are some things to avoid.
- Do not chew gum or suck on hard candy.
- Do not bathe, shower, wash your hair or submerse the equipment in water.
- Avoid static electricity.
- Avoid activities that make you sweat.
- Avoiding working on or being near a laptop that is plugged in or charging.
- Avoid talking on or being near a phone that is being plugged in or charging.
- Avoid touching the electrodes, hear wrap or unplugging the EEG electrodes from the recorder device.
- Avoid banking the equipment, allowing equipment to get wet and making any adjustments to the equipment parts.
What do when the test is over?
- Once the EEG electrodes are removed, the EEG technologist will clean each spot an electrode had been placed with warm water.
- We advise you to wash your hair when you return home.
- Any debris that is left in your hair can be removed with conditioner and a comb. Once removed, you can wash and recondition your hair.
- EEGs are generally safe. In rare instances, prolonged application can cause skin irritation and breakdown. Should this occur, keep the area clean and dry and apply antibiotic ointment such as Neosporin 1-3 time daily for 2-3 days. Let your doctor know if skin irritation does not subside.
- The interpreting physician will compose a detailed report that will be sent to your physician 7-10 days after your recording. v
