Definition
Intracranial pressure (ICP) is the pressure that is exerted on the brain, cerebrospinal fluid, and blood within the skull. In an adult at rest, it is usually less than 10–15 mm of mercury. If ICP rises above normal due to trauma, hydrocephalus, hemorrhage, or tumor, patients can exhibit behavioral changes, headache, decreased consciousness, somnolence, lethargy, seizures, and/or vomiting.
