Acute mountain sickness is a series of pathologic reactions during rapid exposing to low pressure hypoxic high altitude environment, which is a widespread illness among un-acclimatized individuals in plateau. Human always stay in plain will display some common physiological and pathological changes of brain, such as change of cerebral blood flow, cerebral pressure and brain volume. The aim of the present study was to investigate whether there was different change of gray matter volume in some brain regions related to AMS development before, during and after exposing to the real high altitude environment.
