Question

Is High-altitude cerebral edema a serious complication of acute mountain sickness?

Expert Solution
Step 1

The adverse effect of high altitude, caused by quick exposure to low oxygen levels at high elevation, is known as altitude sickness. The mildest form is acute mountain sickness (AMS). People react to high altitude in a variety of ways. Headaches, vomiting, exhaustion, confusion, insomnia, and dizziness are some of the signs and symptoms. High altitude pulmonary edema (HAPE) with shortness of breath or high altitude cerebral edema (HACE) with confusion can result from acute mountain sickness. After prolonged exposure to high altitude, chronic mountain sickness can develop.

Step 2

HACE (high altitude cerebral edema) is a severe form of acute mountain sickness (AMS) that is a rare life-threatening altitude condition. It's caused by leaking capillaries in the brain, which lead to fluid accumulation and enlargement in the brain.
