What is a common late sign of increased ICP?

A common late sign of increased intracranial pressure (ICP) is altered mental status. As ICP rises, it can lead to a decrease in cerebral perfusion, resulting in impaired consciousness and cognitive function. The brain is sensitive to pressure changes, and when the pressure increases significantly, it impacts how information is processed, leading to confusion, disorientation, or even a decreased level of responsiveness.

Increased ICP can often be accompanied by other symptoms such as severe headache, major vital sign changes, and persistent vomiting. However, altered mental status is particularly telling because it indicates that the brain is not functioning properly due to the pressure, making it a key indicator of serious neurological impairment. Early recognition of these signs is crucial for timely intervention to prevent further complications.
