Most elderly individuals can perform reliable spirometry, even with mild cognitive impairment. However, those unable to complete the test may have cognitive deficits needing further assessment.

Area of Science:

  • Gerontology
  • Pulmonology
  • Neuropsychology

Background:

  • Spirometry is crucial for diagnosing lung diseases.
  • Cognitive function in the elderly can impact their ability to perform medical tests.
  • The reliability of spirometry in older adults with cognitive impairment is not well-established.

Purpose of the Study:

  • To investigate if mild cognitive impairment affects the ability of elderly individuals to perform reliable spirometric measurements.
  • To identify potential cognitive factors associated with difficulties in spirometry performance among older adults.

Main Methods:

  • 65 ambulatory subjects aged over 65 years were recruited.
  • Participants underwent cognitive function tests (Symbol-Digit Modalities Test, Trail-Making Test Part B) and spirometry.

  • Standardized questionnaires collected demographic, smoking, and respiratory health data.

    • Main Results:

    • 12.3% of participants could not perform acceptable spirometry maneuvers.
    • These individuals had significantly worse scores on cognitive tests compared to those who could perform spirometry.
    • Among those who completed spirometry, 31.6% did not meet reproducibility criteria; this was not linked to cognitive impairment.

    Conclusions:

    • The majority of older adults, including those with mild cognitive impairment, can perform reliable spirometry.
    • Inability to perform spirometry in the elderly may indicate significant cognitive impairment requiring further evaluation.
    • Spirometry remains a feasible diagnostic tool for respiratory conditions in the aging population.
