What is a concussion?
A concussion is a brain injury that:
• Is caused by a blow to the head or body.
• Can range from mild to severe.
• Can be different for each person.
• Can happen even if you don’t lose consciousness.
The brain is surrounded by a fluid and protective membranes called meninges. A concussion happens when this protection isn’t enough to stop the brain from pushing against the inside of the skull.
The parts of the brain, during a hit, can also move at different speeds, causing damage to the nerve tissue.
