What is a Concussion?

CONCUSSION

Concussion means ‘[a] form of traumatic brain injury induced by biomechanical forces that results in signs and symptoms that are typically resolved spontaneously within 1 to 4 weeks of injury. [1]

IN PLAIN LANGUAGE, A CONCUSSION:

Is a brain injury that causes changes in how the brain functions, leading to symptoms that can be physical (e.g. headache, dizziness), cognitive (e.g., difficulty concentrating or remembering), emotional/behavioural (e.g., depression, irritability) and/or related to sleep (e.g., drowsiness, poor quality of sleep);

May be caused either by a direct blow to the head, face or neck, or a blow to the body that transmits a force to the head that causes the brain to move rapidly within the skull;

Can occur even if there has been no loss of consciousness (in fact most concussions occur without a loss of consciousness); and,

Cannot normally be seen on x-rays, standard CT scans or MRIs.

SUSPECTED CONCUSSION

Suspected Concussion means the recognition that an individual appears to have either experienced an injury or impact that may result in a concussion or is exhibiting unusual behaviour that may be the result of concussion.

Concussion Diagnosis means a clinical diagnosis made by a medical doctor or nurse practitioner.
