What Is a Concussion? A concussion is a type of traumatic brain injuryâor TBIâcaused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth.
By the 18th century, a variety of hypotheses for concussion had emerged. The 19th century discovery of petechial hemorrhagic lesions in severe traumatic brain injury led to these being posited as the basis of concussion, and a similar logic was used later to suggest diffuse axonal injury was responsible.
