Quick Summary

Intracranial pressure (ICP) refers to the pressure within the skull. This pressure is maintained by the balance of brain tissue, blood, and cerebrospinal fluid (CSF). An increase in ICP can occur due to various factors, including hydrocephalus, where CSF accumulates, or cerebral edema, which is excess fluid in the brain tissue. Other causes include tumours, head injuries, strokes, and infections like meningitis. Elevated ICP can lead to reduced blood flow and oxygen to the brain, potentially causing serious damage. Symptoms can range from headache and vomiting to more severe neurological deficits, and if left untreated, it can be fatal. Treatment aims to reduce swelling and restore normal pressure within the skull.12

The circulation of cerebrospinal fluid may be obstructed so that it accumulates in the skull. This condition, called hydrocephalus, may result from congenital stenosis, or narrowing, of the aqueduct of Sylvius, tumours, meningitis, or blood accumulating
