High altitude cerebral edema

A severe, potentially life-threatening condition that can occur at high altitudes, typically above 2,500 meters (8,200 feet). It is characterized by swelling of the brain due to the effects of high altitude, leading to symptoms such as severe headache, nausea, confusion, and loss of coordination. High altitude cerebral edema primarily affects individuals who ascend to high altitudes too quickly without proper acclimatization.
