The study showed that people losing their sense of smell had a higher risk of malnutrition because taste and smell are closely related. Also they may be unable to detect spoiled food, gas leaks and other toxic vapours.
440 subjects in two age groups - 45-years-old and younger and people 60 and over - were tested for responses to two distinct odours and also subsets of those odours. The objective was to find out if age-related differences in the function of Olfactory Sensory Neurons (OSNs) might contribute to the impairment of the sense of smell. Cells from the two groups were biopsied in collaboration with Monell Chemical Senses Center in Philadelphia.
The researchers expected to find fewer OSNs in the older subjects and thought the neurons would be less likely to respond to stimuli. However, they found just as many neurons in the older group as the younger but the over 60s could not differentiate between two odours - they blended together.
