What causes a concussion?
A violent blow to your head and neck or upper body can cause your brain to slide back and forth forcefully against the inner walls of your skull.
Sudden acceleration or deceleration of the head, resulting from certain events such as a car crash or being violently shaken, also can cause brain injury.
These injuries affect brain function, usually for a brief period, resulting in signs and symptoms of concussion
