* significant systemic trauma, ^†number of measurements made. AIS 1 = minor injury; AIS 5 = the most severe of survivable injuries.

AIS = abbreviated injury scale; DAI = diffuse axonal injury; EDH = extradural haematoma; ICH = intracerebral haemorrhage; ICU = intensive care unit; ISS = injury severity score; RTA = road traffic accident; SAH = subarachnoid haemorrhage; SDH = subdural haematoma; TBI = traumatic brain injury.
