Centre for Headache

Migraine and other headache disorders are among the most common health problems in the world. Migraine affects over 1 billion people worldwide, and although it is three times more common in women, ten percent of children and one in 16 men experience migraine. It has been identified by the Global Burden of Disease study as the 2nd leading cause of years lived with disability. Yet, it remains under-diagnosed and under-treated, leaving patients mismanaged and suffering.

The Centre for Headache is the only academic medical centre in Ontario dedicated to research, education, expert evaluation and individualized treatment plans for patients suffering from migraine, cluster, trigeminal autonomic cephalalgias and many other types of headaches.

Canadian Headache Fellowship

The University of Toronto program is an official clinical fellowship program that provides an opportunity for a physician to obtain advanced training and/or to acquire more specialized expertise. Positions are for 1 year and are held by graduates of Neurology residency programs.

  1. Education Session is required for most patients prior to the initial consultation. It is scheduled based on the date referral is received. Attendance will not delay the consultation appointment with one of our specialists. This is an opportunity for patients to learn effective headache self-management strategies to enhance their ability to manage their headache disorder. Our research has shown this program decreases headache related disability and Emergency Department visits.
  2. Initial Consultation where we will develop a Headache Plan of Care to assist patients and their primary care practitioner more effectively manage headaches. Components of the plan will include lifestyle changes, vitamins, medication as well as referrals to support programs as needed.
  3. Follow up is limited to 1-2 visits and then discharge back to family practitioner or referring doctor for ongoing care.

As a specialty clinic we do not provide long term follow-up, unless specialized procedures are necessary and not available locally. In order to serve patients better, if any concerns arise after discharge, we encourage the primary care provider to call one of our specialists for management advice, rather than re-referring.

Please note that we do not prescribe or recommend opioids or marijuana therapy.

As part of an academic teaching hospital, our clinical team may include students and trainees in various disciplines from nursing, allied health and medical residents and fellows. These individuals receive specialized and hands-on training with direct supervision and expertise from our team.
