Diagnostic Neurophysiology (EEG & EMG)

We do more than 25 tests on the brains, nerves and muscles of children
About

We are usually called the EEG Department because the most common test is an EEG (electroencephalogram). Each test can help with your child's diagnosis.

Types of tests

  • Electroencephalography (EEG)
  • Ambulatory EEG monitoring (AM)
  • Intensive video-EEG monitoring (IM)
  • Electromyography (EMG) & nerve conduction study (NC)
  • Evoked potentials (EP), including:
    • Visual evoked potential (VEP)
    • Brainstem auditory evoked response (BAER)
    • Somatosensory evoked potential (SEP)
  • Intraoperative monitoring (IOM)

Some tests require children to be sleep deprived or sedated.

What to bring

Please bring the following to the appointment:

  • BC Services Card (Care Card)
  • Information about current medications and dosages, including herbal supplements and vitamins
  • Soothers, stuffies, blankets - anything comforting that will help your child relax and stay calm

‎Please tell us as soon as possible if you are unable to attend – at least 48 hours ahead, if you can, so that your appointment time can be used by another patient.

If your child has cold or influenza-like symptoms please call us, we might need to reschedule your appointment.

Please let us know, as early as possible, if an interpreter would be helpful.

About us

We work very closely with Neurology, Neurosurgery, Neuropsychology and Orthopedics.

We provide services for inpatients at BC Children's Hospital, Sunny Hill Health Centre for Children, and BC Women's Hospital.

We provide outpatient services for children from all areas of BC and the Yukon.

Internet access

There is free wireless internet available. The network is called CWguest (agree to the terms and conditions prior to browsing).

Prepare

How caregivers can help

Most tests require children to be sleep deprived or sedated.

Follow the appropriate preparation instructions for the type of EEG test.

Do not be late for your appointment. It is very important to be on time! Please try to arrive 15 minutes before the test to find parking and check in with us. Being late for your appointment cuts into your child's testing time.

How to find us

We are located at Entrance 17 of the 1982 Building of BC Children's Hospital. 

Entrance 17 is open from 8am. If your appointment is at 7am please enter via Entrance 53 (Teck Acute Care Centre) and follow the signs for Diagnostic Neurophysiology EEG/EMG.

Valet parking is available from 9am at entrance 11, off of Oak street. There is no extra charge on top of the regular parking rate for this service.

Frequently asked questions (FAQs)

‎After they get the report, your doctor will decide and tell you if they want to re-do the EEG test with sleep.

It usually takes 60-90 minutes to do a routine EEG test and about 60 minutes to do an EMG/NC test.


Sedated tests can take up to 3 hours to complete.


Ambulatory monitoring EEGs can take 3 hours for set up, and the appointment to remove the electrodes on the following day usually takes 30 minutes.

No, the technologist cannot give you the result. A neurophysiology doctor will "read" the EEG and then write a report. The referring doctor will look at the report on their computer and will give you the result at your next appointment.

Yes, you can be in the room with the child during the EEG test. It is important for the child to lay still during the set-up and the test. Please bring anything that will help the child remain calm, such as stuffies, soothers or books.

No, the EEG is a non-invasive test. The electrodes are placed on top of the scalp. Children of all ages have this test done without experiencing pain.

No, the EEG is a non-invasive test. The electrodes are placed on top of the scalp and stuck on with a special paste. The electrodes will be taken off at the end of the test.







Follow-up

Test results

The technologist cannot give you the results of your child's test. A neurophysiology doctor will "read" the EEG and then write a report, which is then uploaded to the electronic patient chart. The referring doctor will look at the report on their computer and will give you the result at your next appointment.

As soon as the report is written and signed by the doctor in our department, the referring doctor will have access to view the results.
