Subjective Symptomatology and Cognitive Performance at High Altitude

Abstract
Further standardization of the General High Altitude Questionnaire (GHAQ) for use in quantifying the severity of Acute Mountain Sickness is described. The results show, as did an earlier study, the questionnaire reliably reflects changes in symptom severity. The amount of decrement on a number of psychomotor tasks was directly related to the degree of severity of the subjective symptomatology of Acute Mountain Sickness. The results also showed several conceptually clear symptom clusters of the GHAQ that appear to reflect different states of subjective symptomatology.
