Tyrolean Researchers Aim to Decode the Mystery of Acute Mountain Sickness

Scientists in Innsbruck are embarking on a mission to unravel the mysteries of acute mountain sickness. Their research focuses on identifying distinct subtypes of this altitude-related ailment. The goal is to pinpoint specific biomarkers within blood and tissue samples that can reliably differentiate these subtypes. This could lead to more targeted prevention and treatment strategies for those affected by the condition. The study involves collaboration with researchers from Eurac Research in Bozen and the University of Lausanne. Their findings are published in the esteemed journal "Redox Biology." Acute mountain sickness, characterized by symptoms such as dizziness, nausea, and headaches, typically affects around 10% of individuals who ascend rapidly to altitudes above 2,500 meters without proper acclimatization. Sport scientist Johannes Burtscher, the lead author of the study, highlighted the challenges in diagnosing the condition. While acclimatization is possible and can significantly reduce the incidence of mountain sickness, accurate diagnosis remains difficult, with various studies yielding different results.

Symptoms, such as dizziness, nausea, or headaches, which indicate acute mountain sickness, occur in about ten percent of all persons not acclimatized to the altitude during rapid ascent. And this mostly from an altitude of around 2,500 meters.
