HACE

High Altitude Cerebral Edema (HACE) is a serious condition that can occur when someone ascends to very high elevations too quickly. It involves brain swelling caused by fluid buildup due to low oxygen levels at high altitude. Symptoms include severe headache, confusion, loss of coordination, and impaired thinking. If untreated, it can lead to coma or death. HACE is a medical emergency, and rapid descent to lower altitudes, along with oxygen therapy and medications, are crucial for treatment. Prevention involves gradual ascent and monitoring for symptoms when at high elevations.
