A concussion is a common head injury, also known as a Mild Traumatic Brain Injury (MTBI). It is an injury that is caused by the brain being shaken around inside the skull after a direct blow to the head, or a sudden jerking of the head or neck when the body is hit. There is a misconception that you have to be knocked out to sustain a concussion, when in fact any contact to the head or body that causes rapid head movement can cause a concussion.

Symptoms of a Concussion**:
  • Decreased Concentration – May have the inability to think or remember recent events. May appear dazed or stunned. People usually describe themselves as being ‘foggy’ or have a ringing in the ears.
  • Vision problems – May have blurry, double vision or “see stars”. Light sensitivity is also common.
  • Emotional Changes – May be irritable, sad, or nervous. Athletes with severe concussions may show unusual emotions, a personality change or inappropriate behaviour.

An athlete who has had one concussion is more likely to have another than an athlete who hasn’t been concussed

 Recovering from a Concussion

  • Get some rest: It is one of the best things you can do to help your brain recover; and when we say rest, we say both physical and cognitive rest. The new concussion consensus indicates that concussed individuals should rest for the first 24-48 hours and then have a gradual and progressive reintroduction to activity as long as symptoms don’t come back or get worse.
  • Take it slow: Everyone recovers at a different pace, some symptoms can last for days, weeks, or longer. How quickly you improve depends on many different factors – the severity of the injury, your age, how many concussions you’ve had and how healthy you were before your concussion.
  • Returning to Play: Remember that there is no such thing as a minor head injury; symptoms may become worse with exertion. An athlete should not return to play until cleared by a professional. Recommendations include a graduated and progressive return to play plan should be implemented, after a modified return to school/work program has been successful (this can be done concurrently with return to play).

Concussion is a topic that affects everyone in sport in some way whether you are a coach, athlete, trainer, physician, or director. If you wish to read more information on concussion prevention, symptoms, or recovery there are a lot of resources available to the sport community.
