Cognitive effects of altitude exposure

This is the authors' abstract. We don't add key points for this paper.

It is a common misconception that cognitive function is impaired in a linear fashion by declining oxygen availability (e.g. at altitude). While this may apply for prolonged exposures to high altitudes (>2500 m), moderate altitude (1500–2500 m) or short intermittent hypoxic episodes can even be beneficial for the brain.
