A concussion is an invisible injury caused by a rapid back-and-forth movement of the head that causes the brain to hit the walls of the skull.
A concussion can result from a direct blow to the head or from an impact to any other part of the body that transmits an impulsive force to the head.
For the complete list of symptoms, please see the tracking sheet in the Concussion Management Protocol: For Use by Educational Institutions and in the Context of Recreational and Sports Activities.
Most concussion symptoms diminish noticeably within 14 days. If the participant’s state of health does not show obvious signs of improvement after 14 days, or if the symptoms persist beyond one month, contact a family doctor or the specialized resource in your region.
A progressive return to activities prevents complications, respects the participant’s capacity to recover and helps maintain social ties.
Compared with other daily life situations, the practice of sports activities is more likely to cause repeated concussions in a short period of time. The victim can also be more vulnerable to a subsequent concussion even after a slighter impact. In such cases, the number of consequences may even increase.
