Neurophysiology laboratory

You will need a doctor’s referral to visit our laboratory.

Routine EEG

This test typically takes one hour.

Sleep deprived EEG

This test will take around 90 minutes. During the test, your awake, drowsy and sleep states will be monitored. Please stay awake the night before your test. You may eat and drink, but you must avoid caffeinated beverages. Please do not drive to or from the test.

An EEG measures electrical signals in your brain. A neurologist will interpret the results and send them to your doctor. Your doctor may schedule an appointment to go over the results with you.

• You do not need to fast before your test. You can continue eating, drinking and taking your regular medications unless your doctor says otherwise.
• Wear comfortable clothing to the test.
• Please come with clean, dry hair that has not been treated with hair products.
• Bring a list of the medications and herbal supplements you are taking.
• Avoid naps, alcohol and caffeine before the test, and follow your doctor’s instructions for the amount of sleep to get the night before.

The technologist will place a cap on your head and put gel in the electrodes before placing them on your head.

During most of the test, you will lie still and relaxed. The technologist may ask you to open and close your eyes, answer questions, do deep breathing or look at flashing lights.

Once the test is complete, the technologist will remove the electrodes and wash the gel off. You may wish to wash your hair again at home.

Please check in at the admitting desk (on the main floor near the front doors) 15 minutes before your appointment.
