Which clinical change is important to monitor as an indicator of worsening intracranial pressure after head injury?

• A. Change in level of consciousness
• B. Numbness in fingers
• C. Weight gain without edema
• D. Hearing loss

Answer: (A)

Rising intracranial pressure after head injury most reliably shows up as a change in mental status. When pressure builds in the skull, cerebral perfusion drops and brain tissue becomes oxygen-starved, leading to alterations in consciousness—from confusion or agitation to drowsiness and eventual coma. Because this change directly reflects deteriorating brain function and the risk of herniation, it’s the most important clinical sign to monitor and track over time, using serial neuro checks or a standardized scale like the Glasgow Coma Scale.

Other options don’t specifically indicate intracranial hypertension in the acute setting. Numbness in fingers points to peripheral or spinal nerve issues rather than global brain pressure. Weight gain without edema and hearing loss aren’t reliable signs of rising intracranial pressure.
