Summary
Extended stays above 5350m improve cognitive function in climbers. Proper acclimatisation enhances memory organization, crucial for complex tasks and reducing accident risk.
Area of Science:
- Altitude Physiology
- Cognitive Neuroscience
Background:
- High altitude exposure can impair cognitive functions.
- Cognitive impairment may increase mountain accident risk.
Purpose of the Study:
- To assess cognitive function changes during high-altitude acclimatisation.
- To investigate the impact of acclimatisation duration on cognitive performance.
Main Methods:
- Studied 17 climbers at 5350m above sea level.
- Utilized a neuropsychological learning test to evaluate cognitive functions.
- Assessed memory tasks, focusing on information organization and storage.
Main Results:
- Spending over 15 days above 5350m significantly enhanced memory task performance.
- Improvements were more pronounced in information organization than storage.
- Inappropriate acclimatisation showed detrimental effects on cognitive functions.
Conclusions:
- Prolonged acclimatisation to high altitude improves cognitive functions, particularly information organization.
- Cognitive impairments from inadequate acclimatisation can affect demanding technical tasks.
- Adequate acclimatisation is vital for climber safety and performance at extreme altitudes.
