CDC Redefines Concussion
The most recent definition of a concussion by the federal Centers for Disease Control (CDC) is as follows: “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.”
This is a very significant change in definition. In the past a concussion was viewed as simply a transient alteration in consciousness caused by head contact or whiplash which might or might not involve injury to the brain. The new definition makes it clear that a concussion is a form of brain injury. Thus any concussion from any source should be taken seriously and the victim should be examined by a doctor.
