off of JR's post, I was curious and googled concussion classifications, thought I would put a few notes from the DSM IV (diagnosis manual):

American Academy of Neurology Concussion Severity- March 1997 Practice

This system was used by our own Dr. Phalin in his doctoral study of different models for detecting recovery in sports concussions.

Concussion Severity: R.C. Cantu, 1991 Cantu's system is often used in research involving sports concussions.
