What is intracranial pressure?

Pressure

To understand intracranial pressure, think of the skull as a rigid box. After brain injury, the skull may become overfilled with swollen brain tissue, blood, or CSF. The skull will not stretch like skin to deal with these changes. The skull may become too full and increase the pressure on the brain tissue. This is called increased intracranial pressure.
