Which symptom best describes High Altitude Cerebral Edema?

Which symptom best describes High Altitude Cerebral Edema?

• A. Productive cough
• B. Altered mental status with ataxia and cranial nerve palsies
• C. Hemorrhagic bullae on the skin
• D. Severe leg swelling

Answer: (B)

High altitude cerebral edema causes brain swelling from hypoxia, leading to neurologic dysfunction. The hallmark is altered mental status combined with ataxia, often with cranial nerve signs, reflecting cerebral involvement. This is distinct from high-altitude pulmonary edema, which presents with respiratory symptoms like a productive cough from lung edema. The other options don’t fit altitude-related brain involvement. So the symptom cluster of confused or altered thinking with ataxia and cranial nerve palsies best describes HACE, signaling the need for rapid descent, oxygen, and appropriate therapy.
