Concussions - An Invisible Brain Injury

A concussion can occur from a blow to the head or body that causes the brain to move rapidly back and forth within the skull. It is a brain injury that causes changes in how the brain functions, leading to symptoms that may include:

  • Headache;
  • Dizziness;
  • Difficulty concentrating or remembering;
  • Depression or irritability; and
  • Drowsiness or difficulty falling asleep.

If a concussion is suspected, it is important to seek a diagnosis from a medical doctor or nurse practitioner - only a medical doctor or nurse practitioner can diagnose a concussion.  

The health unit works in partnership with local community organizations and institutions in an effort to prevent head injuries in our communities.


  • Work with school boards & sports organizations to create concussion policies and procedures.
  • Provide access to research and resources for community stakeholders.
  • Advocate for policy change that will reduce concussions.
  • Highlight the importance of assessing head injury across the lifespan, and beyond sports.

What Matters to Your Health

Concussions occur most often in children when they are playing sports.  Many of the resources below are geared to sports related concussions. However, anybody - a child, adult, or senior can be impacted by a concussion when they experience a blow to their head or body. Outside of sport, concussions are often caused by a fall or a collision. 

Preventing  concussions and head injuries is most successful when guidelines are followed. In sports, parents, coaches, trainers and athletes need to be properly educated on the safety guidelines and ensure they are followed.

Keep in mind that protective equipment can only reduce the risk and severity of injuries to the face and skull, they cannot prevent a concussion.
