A concussion happens when your brain moves rapidly back and forth inside your skull, which is the bony case that protects your brain. This sudden movement can cause the brain to bounce or twist, leading to chemical changes or damaging brain cells.
Because your brain controls everything you do, this injury can affect your ability to think, move, and process information. While it is often called a mild injury because it is usually not life-threatening, it is important to take it seriously to give your brain time to heal properly.
