Sensory Functioning in Older Adults: Relevance for Food Preference

Area of Science:

• Gerontology
• Neuroscience
• Sensory Science

Background:

• The global population is aging, with older adults forming a significant consumer demographic.
• While psychophysical studies have documented sensory, perceptual, and cognitive changes in aging, research is less comprehensive for the oldest age groups.
• Existing knowledge gaps hinder a full understanding of how aging impacts sensory experiences, particularly taste and smell.

Purpose of the Study:

• To explore the utility of neuroimaging techniques in investigating age-related alterations in central nervous system function.
• To examine how changes in taste and smell perception influence sensory processing, reward valuation, and food consumption behaviors in older adults.
• To bridge the knowledge gap regarding the neural underpinnings of sensory perception in the old-old and oldest-old populations.

Main Methods:

• Utilizing advanced neuroimaging tools to probe brain activity.
• Focusing on neural correlates of taste and smell perception.
• Analyzing central nervous system responses to food stimuli.

Main Results:

• Neuroimaging provides a novel approach to studying age-related sensory and cognitive changes.
• The research highlights the potential for brain imaging to reveal how taste and smell alterations affect older adults.
• Early findings suggest a link between neural function and sensory perception in the aging brain.

Conclusions:

• Neuroimaging tools offer significant potential for understanding the neural basis of sensory perception in aging.
• This research can enhance our comprehension of older adults' behavior as consumers, particularly concerning food.
• Further investigation using brain imaging is warranted to fully elucidate age-related changes in sensory processing and their behavioral consequences.
