A concussion is a type of traumatic brain injury, or TBI, caused by a bump, blow, or jolt to the head that can change the way your brain normally works. Concussions can also occur from a fall or a blow to the body that causes the head and brain to move quickly back and forth.
Health care professionals may describe a concussion as a “mild” brain injury because concussions are usually not life-threatening. Even so, their effects can be serious.
You can’t see a concussion and some people may not experience and/or report symptoms until hours or days after the injury.The good news is that most cases are treatable and there are several ways to help prevent injury.
