Intracranial Pressure

Intracranial pressure (ICP) refers to the pressure inside your skull or cranium, where your brain is located. This pressure is usually stable, but when it rises, it can lead to various health issues. In this article, we’ll simplify the complex terminology surrounding ICP to help you grasp the basics of its types, causes, symptoms, diagnostic tests, treatments, and medications.

Types of Intracranial Pressure:

  1. Normal Intracranial Pressure (ICP): The typical pressure inside your skull, which is around 5-15 mmHg.
  2. Elevated Intracranial Pressure: When the pressure exceeds normal levels.

Causes of Elevated Intracranial Pressure:

  1. Head Injury: A blow to the head can cause swelling and increased pressure.
  2. Brain Tumors: Growths in the brain can press against it.
  3. Hemorrhage: Bleeding in or around the brain can elevate pressure.
  4. Meningitis: Inflammation of the brain’s protective membranes can increase ICP.
  5. Hydrocephalus: Excess cerebrospinal fluid builds up in the brain.
  6. Stroke: A blocked or ruptured blood vessel in the brain can lead to pressure.
  7. Intracerebral Hemorrhage: Bleeding within the brain tissue.
  8. Encephalitis: Brain inflammation due to viral infection.
  9. Brain Abscess: A pocket of infection in the brain.
  10. Seizures: Repeated seizures can elevate pressure.
  11. High Altitude: Rapid changes in elevation can cause altitude sickness, affecting ICP.
  12. Brain Edema: Swelling of the brain tissue.
  13. TBI (Traumatic Brain Injury): Any injury to the brain can increase ICP.
  14. Brain Aneurysm: A weakened blood vessel can rupture, causing pressure.
  15. Dehydration: Insufficient fluids can lead to brain dehydration and pressure.
  16. Toxic Ingestion: Certain substances can cause brain swelling.
  17. Blocked Blood Flow: Reduced blood supply to the brain can result in ICP.
