The breakdown of the tight endothelial junctions that make up the blood–brain barrier causes extravasation of fluid, ions, and plasma proteins, such as albumin, into the brain parenchyma. [18] Accumulation of extracellular fluid increases brain volume and then intracranial pressure causing the symptoms of cerebral edema. [1]
