Excerpt
Attempts have been made to classify concussion severity in
the interest of assessment and tailoring management/intervention. Maroon
et al. (1980) proposed a graded system of concussion classification
on the basis of LOC. Under this system, "mild concussion" referred
to injuries with no LOC, "moderate concussion" included injuries
with brief LOC and retrograde amnesia, and "severe concussion" encompassed
injuries with LOC of 5 minutes or more. Cantu (1998)
included length of PTA, defined as any memory problems associated
with brain trauma such as retrograde and anterograde amnesia, in
addition to LOC, to create guidelines for rating concussion severity
(Table 27–2).
