The brain floats within the skull, surrounded by cerebrospinal fluid, which cushions it from the light bounces of everyday movement. But the fluid may not be able to absorb the force of a sudden hard blow or a quick stop. A violent jar or shock to the head can cause a concussion, a type of traumatic brain injury (TBI) resulting in bleeding in or around the brain and the tearing of nerve fibers.


A concussion causes at least a temporary loss in brain function. Although losing consciousness is a common sign of a concussion, it's possible to suffer a concussion without being completely knocked out.
