Traumatic brain injury occurs when a sudden trauma causes brain damage. TBI can result from a closed head injury or a penetrating head injury. Symptoms of a TBI can be mild, moderate, or severe, depending on the extent of the damage to the brain. Outcome can be anything from complete recovery to permanent disability or death. A coma can also affect a child's brain.

The first video was the one I was thinking of. Now I get to watch two more :)
Thanks again Elaine.
Glad I was able to find the one you wanted. I have it on DVD, and it's a really good one.
