Which consequence is associated with increased intracranial pressure if not managed?

• A. Brain damage
• B. Kidney failure
• C. Liver failure
• D. Peripheral neuropathy

Answer: (A)

Elevated intracranial pressure is dangerous because the brain is enclosed in a rigid skull, so any rise in pressure reduces cerebral perfusion and can quickly injure brain tissue if not treated. As ICP climbs, cerebral perfusion pressure (CPP) drops (CPP = mean arterial pressure minus ICP). When CPP falls below the level needed to supply oxygen and glucose to neurons, the brain becomes ischemic, edema worsens, and neuronal injury accumulates—eventually leading to brain damage. If pressure continues to rise, brain herniation can occur, which is a life-threatening shift of brain tissue that can cause irreversible injury or death. The other organs listed aren’t the direct, immediate victims of unmanaged ICP. Kidney and liver failure or peripheral neuropathy aren’t caused by the pressure dynamics inside the skull in the same acute way, though systemic illness or prolonged critical illness can affect them separately. The key consequence of not managing high ICP is brain damage from impaired perfusion and potential herniation.
