Subarachnoid cyst and ascent to high altitude--a problem?

abstract：:Acute altitude exposure may lead to acute mountain sickness (AMS). Increased awareness of altitude-related health hazards in trekkers may accompany a decrease in AMS prevalence. We compared awareness and AMS prevalence in trekkers in two cohorts on an altitude trek up to 5400 m and assessed risk factors for AMS by rep...
