TIA / Stroke / Neurology (TSN) Clinic

  • We provide education on lifestyle and risk management, stroke prevention and warning signs for stroke;
  • We facilitate referral of appropriate patients to local cardiovascular rehabilitation services for ongoing secondary prevention and chronic disease management; and
  • We facilitate linkage to community programs for secondary prevention and chronic disease management.

What tests will I have?

You may be asked to have:

  • Blood work: The blood work will test your cholesterol levels, blood sugar levels and kidney and liver function.
  • A carotid doppler: The carotid doppler is an ultrasound of major arteries of your neck, which supply your brain with oxygen-rich blood. This test will look for narrowing or blockages in these vessels.
  • An echocardiogram: The echocardiogram is an ultrasound of your heart to check its size and how it pumps, and looks for the presence of blood clots.
  • A holter monitor: The holter monitor is a portable monitor, consisting of electrodes worn on the chest for 24 or 48 hours during normal daily activities, including work. It records your heart's rhythm and checks for abnormal heartbeats that could lead to blood clots.
  • Computed tomography (CT) of the head: A CT scan can detect a blood clot or bleeding within the brain and help confirm that you have had a stroke. It may also help determine the type of stroke.
  • Magnetic Resonance Imaging (MRI):  An MRI scan can detect brain tissue that has been damaged by a stroke. It can also help identify things that resemble stroke, known as “stroke mimics.”
