52The [blank_start]Monro[blank_end]-[blank_start]Kellie[blank_end] doctrine states that three things exist within the fixed dimensions of the skull: [blank_start]blood[blank_end], cerebrospinal fluid, and the brain. An increase in any one component must lead to a [blank_start]decrease[blank_end] in one (or both) of the other components, otherwise the [blank_start]intracranial[blank_end] pressure will increase.

If the pressure is severe enough, this can lead to [blank_start]herniation[blank_end] of brain tissue out of the skull. If this occurs at the brainstem, it can lead to [blank_start]coma[blank_end] or even brain [blank_start]death[blank_end].
