This study intends to recruit healthy subjects from plain area to 3000 m altitude group (N=40) and 4000 m altitude group (N=40).~First, subjects completed baseline cognitive function tests and information collection in the plain area.~Second, the tests were repeated on day 1, day 3 and day 7 after the two groups of subjects entered the area at different altitudes.~Finally, analyze and find out the main types of cognitive impairment, and explore the related indicators of cognitive impairment in EEG.
By observing the changes of cognitive function of subjects after moving from plain to plateau, this study aims to find out the main types of impaired cognitive function and explore the indicators related to impaired cognitive function in the EEG.
