Concussions are no longer considered as minor medical events. Our research has shown that it is important to recognize concussion and institute early evidence-based treatment. Concussions are now regarded as a major public health problem, and the Canadian Concussion Centre has developed a multidisciplinary approach to early recognition and treatment.

Today we know that a concussion is a brain injury. We also know that sustaining multiple concussions can result in long-term consequences for some individuals, including a brain condition called chronic traumatic encephalopathy (CTE) which can resemble Alzheimer's or Parkinson's disease. Unfortunately, we do not know how to provide effective treatment for CTE. Thus, we are very active in trying to prevent multiple concussions whether in sports, at work, at home, or on the highways.

Overview of Our Research


Clinical Research Purposes

  • To study involving former professional contact sports athletes including football and hockey players as well as boxers, and other professional athletes who undergo a neurological and neuropsychological assessment as well as brain scans (MRIs), and PET scans to help better understand the changes in the brain that may occur due to multiple concussions.
  • To improve diagnostic imaging techniques to diagnose the full spectrum of concussions – from acute concussion to persisting concussion symptoms (PCS) to CTE – and to discover ways to grade the severity of these conditions.
  • Clinical research into new treatment approaches for people with PCS, such as treatment for dizziness, headaches, and screen intolerance.
  • Searching for biomarkers including blood tests that may be used to diagnose a concussion as well as identifying any susceptibility to concussion within families through genetics.

Brain Donation Research Program for Concussion and their Consequences

Encouraging professional athletes or their families, on their behalf, to donate their brains to our Brain Donation Research Program for Concussion and their Consequences upon their death, so that further study and understanding of concussions can be achieved through post-mortem examinations.

Research Details of the Chronic Traumatic Encephalopathy (CTE) study at the Canadian Concussion Centre (CCC)

Chronic Traumatic Encephalopathy (CTE) is characterized by deposits of an abnormal protein in the brain called tau, and by shrinkage of the brain. There is currently no effective way to diagnose this condition in life or to treat this condition which has been shown to cause neuropsychiatric symptoms and a progressive loss of cognitive functions leading to the development of dementia.

One of the main goals of the research team at the Canadian Concussion Centre is to examine the possible relationship between repeated concussions and late deterioration of brain function leading to CTE. Individuals who have sustained multiple concussions from playing sports seem to be at greater risk of developing CTE, but brain deterioration may also occur as a result of sustaining concussions in motor vehicle crashes, industrial injuries or falls.

Methods

Our ongoing study at the CCC is looking at the potential effects of CTE in two ways:

  • Current and retired professional football and hockey players, and other professional athletes who have had concussions undergo multi-modal investigations that include neurological, neuropsychiatric, and neuropsychological assessments, as well as blood draw, MRI and PET brain scans. Our team then continues to follow them to observe how their symptoms progress over time.
  • Since CTE can currently only be diagnosed after death, our team also conducts autopsies and analyses of brains that were donated to the CCC by professional athletes or their families on their behalf. Members of the public who have sustained repetitive concussions are also welcome to will their brains to the Canadian Concussion Centre to help further this research. Learn more about brain donation.
  • Through these two methods of research, our team conducts a detailed research analysis of these cases to determine how post-traumatic brain degeneration, including CTE, is produced.

These workshops launched by the Canadian Concussion Centre in 2014, and have been held as quarterly workshops hosted at the Toronto Western Hospital (TWH). These free, 2-night workshops (each two hours long) were developed by members of the Canadian Concussion Centre, Toronto Western Hospital (TWH) and the Cognitive Neurorehabilitation Sciences Lab at the Toronto Rehabilitation Institute. The Labourers International Union of North American (LiUNA) has continued to be the principal sponsor our Education and Support Workshops for concussed individuals with persistent symptoms. In 2020, because of the COVID-19 pandemic the CCC has launched virtual online workshops in May, 2020 to support patients and their families during the pandemic. The aim is to expand these virtual workshops in 2021 with a focus on treatment of concussions and their consequences.

At the concussion clinics of the Canadian Concussion Centre, beginning in 2019, we have been able to give our patients an outstanding handbook containing extensive information about how to manage their persisting symptoms. This handbook  was created by the staff of the Centre with input from other experts, and took more than a year to complete. The handbook "Managing Persistent Post-Concussion Symptoms" is now being distributed free to the patients at the concussion clinics and concussion workshops, and carries a note on the first page that this was made possible as a result of the support received from LIUNA.

Trainees and Healthcare Professionals Training


The CCC aims to provide research findings and recommendations to sports organizations, employers, and health care professionals so the best care can be provided during return to sports, return to school or return to work. With respect to sports, we strive to ensure that all sports can be enjoyed by athletes of all ages and abilities with minimal risk of further concussions. We want young people to keep playing collision sports, but we want these sports to be as safe as possible. We also want the school and work environments to be as safe as possible and return to school or work to occur on a graduated basis with any necessary accommodations being provided. We now have a specific research program on return to work.

Concussion Fellowship


The clinical research Fellowship in concussion is a 1-2 year fellowship program that is open to applicants who have completed residency training in Neurology, Neurosurgery or Physical medicine and rehabilitation or are physicians holding a sports medicine certificate and wish to pursue further training in the clinical aspects and research of concussion. This is the first fellowship in sports concussions in Canada. The CCC has trained 7 Concussion Fellows, each for at least one year. The concussion fellows attend the CCC's Concussion Clinics and are involved in various concussion research projects. Dr. Carmela Tartaglia is in charge of the Concussion Fellowships. This is the only Concussion Fellowship in Canada and is designed to enhance the management of patients with concussions by providing an exceptional learning opportunity and research training to trainees.

Join Our Study


Participation in the Clinical Research Study

Participating in the clinical study of concussions at The Canadian Concussion Centre involves:

  1. A neurological assessment
  2. A neuropsychological assessment
  3. A blood test
  4. An MRI of the brain
  5. A Positron Emission Tomography (PET) scan of the brain
  6. Oculomotor testing

The assessments are completed in Toronto, Ontario over the course of two days; the neurological and MRI assessments are performed at the Toronto Western Hospital, the neuropsychological assessment is at the Toronto Rehabilitation Institute, and the PET scan is conducted at the Centre for Addiction and Mental Health (CAMH).

Due to restricted research funding, at the present time we are only accepting former professional and amateur athletes. If you are a professional or amateur athlete with a history of concussions, and would like to participate in our clinical study, please contact:
