What is a Concussion?
A concussion is a mild brain injury resulting from a blow to the head that causes changes in brain function. It is important to note that not all concussions lead to unconsciousness. Depending on the severity of the blow and which area of the brain is injured, changes may be temporary.
A number of symptoms can be identified, including:
- Memory loss
- Behaviour changes
- Lack of concentration
- Loss of balance/dizziness
- Blurred vision
- Headaches
- Ringing in ears
- Nausea/vomiting
- Slurred speech
- Sleepiness
It is important to follow a physician’s orders of care when returning home, as you or your loved one may be at risk for second impact syndrome following a concussion. Second impact syndrome refers to the fact that there is a high risk for re-injury even with minimal impact to the head. It is for this reason that returning to physical activity involving direct contact such as sports needs to be reintroduced into an individual’s life style slowly after a physician has completed a full assessment.
