Did you know that your brain sits relatively freely in the skull? It’s not really tied down to anything. It’s just sitting there, surrounded by cerebrospinal fluid to protect against mild impacts to the head. A concussion begins at the point where that fluid is no longer sufficient protection, where an impact or torsion is so great the biological defense we’ve evolved is overwhelmed. The brain slides around your skull, hitting bone hard enough to cause damage to the tissue and dysfunction of your neurons. The extent of that damage and the force required to impart it varies between incidents — a concussion of identical severity can result from two impacts of different severities.
