Parameters:
(1) initial Glasgow Coma Score (GCS)
(2) loss of consciousness (LOC)
(3) length of alteration of consciousness (AOC)
(4) length of post-traumatic amnesia (PTA)
(5) neuroimaging findings
Parameter
Mild TBI
Moderate TBI
Severe TBI
initial GCS
13 to 15
9 to 12
3 to 8
LOC
<= 0.5 hours
0.5 to 24 hours
> 24 hours
length of AOC
<= 24 hours
length of PTA
<= 1 day
1 to 7 days
> 7 days
neuroimaging
normal
normal or abnormal
Variants:
(1) an older version says that LOC for moderate TBI was up to 6 hours rather than 24.
(2) focal neurologic deficits may be included
