Many people are not aware that a concussion is an injury to the brain.
- It is defined as a temporary alteration in mental function that may
or may not be associated with a loss of consciousness. 1
- The trauma is usually a blow to the head. But, many experts believe
that it is possible to have a concussion without a blow to the head,
as in a whiplash injury.
- In fact, the term "mild traumatic brain injury" is sometimes
used to describe a concussion.
