High altitude cerebral edema

High altitude cerebral edema is a severe disorder of the central nervous system caused by acute hypoxia. It is characterized by acute onset, and clinical manifestations are characterized by severe headache, vomiting, ataxia, and progressive disturbance of consciousness. The pathological changes mainly include ischemic or hypoxic damage to the brain tissue, and cerebral circulation disorders, resulting in cerebral edema and increased intracranial pressure. If not treated properly, it is often life-threatening. In the past, it was often called high mountain (original) coma, cerebral alpine disease, acute high altitude encephalopathy and high altitude cerebral hypoxia syndrome.
