CTE Causation
Through education and prevention programs, and research with our Global Brain Bank partners, we’re working tirelessly to End CTE.
The Consensus
A Global Recognition of Causation
In 2022, the U.S. National Institutes of Health (NIH) and National Institute of Neurological Disorders and Stroke (NINDS) formally recognized that Chronic Traumatic Encephalopathy (CTE) is caused in part by repetitive head impacts, such as those that occur in contact sports. This landmark recognition was followed by several major medical and sports organizations worldwide.

Canada
The Gap in Canada
Despite the growing global consensus, no major Canadian sport or medical organization has yet formally recognized the link between repetitive head impacts and CTE. CLF Canada is working to change this to ensure better protection and support for Canadian athletes.
