Overview

Cognitive functions decline initially at high altitude, indicating potential acclimatization benefits.

Key Points

  • The aim was to assess cognitive functions at high altitude, particularly immediate memory and concentration.
  • Evaluated cognitive performance of 25 healthy male subjects at 4,000 m altitude.
  • Monitored cognitive functions over several months of altitude exposure.
  • Recorded sea-level performance before and after altitude exposure.
  • Immediate memory remained stable at high altitude.
  • Concentration declined initially but remained lowered throughout the stay.
  • Other cognitive functions deteriorated in the first month but showed improvement later, possibly due to acclimatization.
  • Sea-level performance scores returned to near baseline levels after altitude exposure.
