What causes a concussion?
A concussion occurs when a head injury causes the brain to move out of its normal position. This results in disruption to a part of the brain called the reticular activating system (RAS). The RAS is in the middle of the brain and is responsible for regulating awareness and consciousness. It also blocks out unimportant information to allow you to focus on details you need.

- Loss of balance
- A feeling of being stunned or dazed
