Summary

Aging significantly impacts the sense of smell in individuals over 65, leading to olfactory disorders. This age-related decline affects odor perception and identification, potentially impacting nutrition in the elderly.

Area of Science:

  • Gerontology
  • Neuroscience
  • Sensory Science

Context:

  • Olfactory disorders are a common health concern in aging populations.
  • Age-related olfactory decline is linked to changes in the naso-sinus system and potential early dementia.
  • Understanding these changes is crucial for geriatric care.

Purpose:

  • To investigate the precise effects of aging on the human olfactory system.
  • To explore the morphological and functional changes in olfactory pathways due to aging.
  • To elucidate the impact of olfactory deficiency on elderly individuals' quality of life.

Summary:

  • Aging, particularly after 65, impairs olfactory thresholds, odor intensity estimation, and odor identification/memorization.
  • Alterations in the nasal cavity and olfactory neuroepithelium contribute to age-related olfactory dysfunction.

  • Elderly individuals can improve olfactory performance through learning, despite age-related neural changes.

    • Impact:

    • Age-related olfactory dysfunction affects the peripheral and central olfactory pathways.
    • Olfactory deficiency in the elderly can contribute to eating problems and reduced nutritional intake.
    • This research provides insights into the functional consequences of sensory deficits in aging.
