Neurointensive care of traumatic brain injury in the elderly-age-specific secondary insult levels and optimal physiological levels to target need to be defined.

Elderly ≥ 65 have different patterns of secondary insults/physiological variables, which is independently associated to age. The finding that SBP > 180 increased the odds of favorable outcome in the elderly but decreased the odds in younger patients may indicate that blood pressure should be treated differently depending on age.
