Summary
Age-related decline in taste and smell is common, impacting nutrition and behavior in older adults. Further research is needed to understand these chemosensory changes and their consequences.
Area of Science:
- Gerontology
- Neuroscience
- Nutritional Science
Background:
- Scientific consensus indicates age-related decline in taste and smell acuity.
- Chemosensory impairments in the elderly are linked to normal aging, diseases (e.g., Alzheimer's), medications, and environmental factors.
Framework:
- Workshop focused on reviewing current knowledge, identifying knowledge gaps, and strategizing future research on age-related taste and smell changes.
- Emphasis on the behavioral and nutritional consequences of these sensory impairments.
Implementation:
- Reviewed existing scientific literature on taste and smell changes in the elderly.
- Identified areas lacking comprehensive understanding, particularly regarding underlying mechanisms.
- Proposed future research directions for chemosensory assessment and nutritional impact.
Implications:
- Highlights the need for further investigation into the basic mechanisms of aging's effect on chemical senses.
- Underscores the importance of improved chemosensory testing and understanding the link between sensory dysfunction, food intake, and nutrition in older populations.
