Quick fact

A concussion can occur without a direct hit to the head—sudden whipping of the neck (like a car crash) can generate enough brain-skull motion to cause injury.

Why this is interesting

You’ve seen athletes get tackled or hit, but have you ever wondered why some blows to the head cause a concussion while others don’t? It’s not just about force—it’s about how the brain moves inside the skull.
