Which finding is the hallmark of High Altitude Cerebral Edema?

• A. Severe headache with confusion
• B. Shortness of breath
• C. Ataxia with AMS
• D. Abdominal pain

Answer: (C)

In High Altitude Cerebral Edema, the key clue is the combination of cerebellar dysfunction with altered mental status. Ataxia with altered mental status signals cerebellar swelling from the cerebral edema and is the most specific clue for HACE among altitude illnesses. Shortness of breath points to High Altitude Pulmonary Edema, while abdominal pain isn’t a typical feature of HACE. Recognizing this specific combination is crucial because it prompts urgent descent and appropriate treatment to prevent deterioration.
