According to the 4th International Conference on Concussion in Sport in 2012 a concussion is a “brain injury and is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces”.

  1. Contrary to popular belief someone does NOT have to experience loss of consciousness to experience a concussion. Statistics show that less then 20% of concussions are actually accompanied by loss of consciousness.
  1. Signs and symptoms do not necessarily show up immediately. In some instances, symptoms may not begin until several hours to days following an injury.
  1. Symptoms may be physical, emotional/behavioural or cognitive. The most commonly reported symptoms relating to concussion are headaches (94.3%), dizziness/unsteadiness (75.5%), difficulty concentrating (53.9%), confusion/disorientation (44.0%), visual disturbance/sensitivity to light (34.4%).
  1. Approximately 80-90% of concussions will resolve in 7-10 days, however it should be noted that children and adolescents might experience longer recovery times.
