What does elevated intracranial pressure (ICP) indicate?

Elevated intracranial pressure (ICP) signifies a potential danger to the brain, which is why the selected answer is correct. When ICP increases, it can lead to a decreased perfusion pressure, restricting blood flow to brain tissue and ultimately affecting its function. This condition may result from various factors, including brain injury, hemorrhage, tumors, or conditions like hydrocephalus.

High ICP can cause significant complications such as brain herniation, where brain tissue shifts due to pressure, leading to neurological deficits or even fatality. Monitoring and addressing elevated ICP are crucial to prevent irreversible damage and ensure that cerebral blood flow remains adequate to sustain brain metabolism.
