High altitude cerebral edema (HACE) is a severe type of acute mountain sickness (AMS) that occurs in response to a high altitude hypobaric hypoxic (HH) environment. High-altitude pulmonary edema may be fatal within a few hours if left untreated. One severe consequence of altitude illness is swelling of the brain (high-altitude cerebral edema [HACE]). High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude.It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.  |  High Alt Med Biol.
