What is a Concussion?

A concussion is a type of traumatic brain injury, or TBI, caused by a traumatic force to the head or upper body that causes the brain to shake inside of the skull. The injury is defined as a concussion when it causes a change in mental status such as amnesia, disorientation, mental fogginess, confusion, nausea or vomiting, blurred vision or loss of consciousness. There are 21 symptoms that have been demonstrated to be caused by a concussion. Loss of consciousness is not an indicator of injury severity. Because no two concussions are exactly alike and symptoms are not always definite, the injury’s severity, effects and recovery are sometimes difficult to determine.
