What is the normal range for intracranial pressure in adults?

The normal range for intracranial pressure (ICP) in adults is typically between 7 and 15 mmHg. This range indicates that under normal physiological conditions, the pressure within the skull, which is influenced by the volume of brain tissue, blood, and cerebrospinal fluid, remains stable to allow for proper brain function and homeostasis. Values outside of this range may indicate pathological conditions requiring further investigation or intervention.

When ICP rises significantly beyond this range, particularly above 15 mmHg, it can lead to neurological issues, including potential brain herniation. Therefore, awareness of the normal ICP range is crucial for healthcare professionals in diagnosing and managing conditions that could affect intracranial dynamics.
