Neurology

The Neurophysiology Lab examines disorders of the brain, spinal cord and nerves throughout the body. The nervous system controls all sensations and behaviors and can manifest in a wide variety of symptoms. The Neurophysiology Lab provides patients with different types of diagnostic tests including electroencephalogram (EEG) and electromyography (EMG). This service is part of our medical diagnostics portfolio, which specializes in diagnostic services related to cardiology, respiratory and neurology. The department provides clinical and diagnostic interventions to an inpatient and outpatient population.

Our team of professionals that support the patient care and experience includes highly experienced EEG/EMG technologists and a team of physicians specializing in neurology.

Electroencephalogram (EEG)

An electroencephalogram (EEG) is a test used to evaluate that electrical activity in the brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help track and record brain waves which detect potential problems associated with this activity. Small, flat metal discs called electrodes are attached to the scalp with wires. The electrodes analyze the electrical impulses in the brain and send signals to a computer, where the results are recorded. An EEG is one of the main diagnostic tests for epilepsy. An EEG may also play a role in diagnosing other brain disorders.

Electromyography (EMG)

Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals using tiny electrodes to transmit/detect electrical signals. The results are interpreted by a neurologist. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Patients will be notified of the time of your appointment by medical diagnostics, either by telephone or mail. Depending on the test you are having, some test preparation instructions may need to be followed. Failure to confirm may result in the cancellation of the appointment.

Two working days’ notice is requested to change or cancel an appointment.

Here are a few things to keep in mind when coming for your appointment:

When you arrive:

  • Please proceed to neurology reception on the third floor of the Morrow wing (Room 3M 03).
  • Please arrive 15 minutes before your appointment.
  • Make sure you have your health card (OHIP card) – you will need this to register.
  • You will wait in the waiting room until one of the technologists calls you in for your appointment.

How long will your appointment be?

  • Appointments are usually 45 to 60 minutes long depending on what tests have been ordered. We do our best to stay on time but sometimes appointments can be delayed by unforeseen circumstances.
  • Once your test is complete the results are sent to your doctor. Your doctor will discuss the results with you.
