Definition
Is when fluid builds up around the brain, causing an increase in pressure known as intracranial pressure. Swelling or inflammation is part of the body's natural response to injury.
Pathophysiology
Cerebral edema at cellular level is complex. Damaged cells swell, injured blood vessels leak and blocked absorption pathways force fluid to enter brain tissues. ... Sodium builds up within the cell creating an osmotic gradient and increasing cell volume by entry of water.
