Atypical neurological symptoms at high altitude: a systematic literature review

Travel Medicine and Infectious Disease
Background: Acute Mountain Sickness (AMS) is a prevalent and potentially debilitating condition affecting individuals who participate in high-altitude journeys, mostly above 2500 m.

Do acute mountain sickness and psychiatric disorders show overlapping symptoms?

Current Issues in Sport Science
The Lake Louise Score (LLS) is a common tool for diagnosing acute mountain sickness (AMS) after a recent gain in altitude. Required symptoms (headache, dizziness, fatigue or gastrointestinal symptoms) are unspecific, subjective and not detectable by ...

Analysis of the individual risk of altitude decompression sickness under repeated exposures [PDF]

In a case-control study, researchers examined the risk of decompression sickness (DCS) in individual subjects with higher number of exposures. Of the 126 subjects, 42 showed one or more episodes of DCS.

Visual and vestibular reweighting after cyber‐ and space‐sickness

Experimental Physiology, EarlyView.
Abstract Sensory conflicts are widely recognized as the primary drivers of motion sickness (MS), though the underlying integrative processes remain poorly understood. This study investigated sensory reweighting following exposure to two different sensory conflict paradigms. Visual and vestibular reflexes were assessed before and after sensory conflict.

Acute mountain sickness: pathophysiology and prevention

Quality in Sport
This review discusses the epidemiology, pathophysiology, prevention and treatment of acute mountain sickness (AMS). Key mechanisms including changes in blood-brain barrier permeability, activation of the renin-angiotensin-aldosterone system and the role

The effect of exercise on venous gas emboli and decompression sickness in human subjects at 4.3 psia [PDF]

The contribution of upper body exercise to altitude decompression sickness while at 4.3 psia after 3.5 or 4.0 hours of 100% oxygen prebreathing at 14.7 psia was determined by comparing the incidence and patterns of venous gas emboli (VGE), and the ...

Pulmonary arterial mechanoreceptors modulate exercise‐induced sympathetic activation in healthy humans during moderate‐intensity hypoxic exercise

The Journal of Physiology, EarlyView.
Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Osteometric and Morphologic Study of Appendicular Skeletons of Female Simien Sheep in Wogera District, Northwest Ethiopia

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
ABSTRACT Simien sheep are the predominant fat‐tailed sheep breeds found in Northwest Ethiopia, playing a significant role in the livelihood of resource‐poor farmers. This study provides the morphometric and morphological descriptions of the appendicular skeletons of Ethiopia's indigenous female Simien sheep.

High-altitude Cerebral Edema and High-altitude Pulmonary Edema Diagnosed in the Desert: A Case Report

Clinical Practice and Cases in Emergency Medicine
Introduction: Acute mountain sickness, high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE) are a spectrum of high-altitude conditions, with HACE being the most life-threatening.
