Olfactory disorders have been documented both in aging and in various neurodegenerative and psychiatric conditions, with memory loss as a frequent feature. The present investigation aimed at developing a standardized multiple choice odour recognition test, based on the “Sniffin’ Sticks” test kit. The test was applied on two occasions at a distance of approximately two weeks from each other to a group of 108 normosmic, healthy volunteers (51 men, 57 women, age range 18-95 years). The results showed that performance decreased significantly with increasing age, particularly after the age of 60. The test-retest Pearson’s coefficient of correlation between the two repeated administrations was .90, indicating a high reliability of the task. No sex-related differences were found. These data suggest that the present odour recognition memory test may be suitable for the routine clinical assessment of olfactory performance.

Abstract

Olfactory disorders have been documented both in aging and in various neurodegenerative and psychiatric conditions, with memory loss as a frequent feature. The present investigation aimed at developing a standardized multiple choice odour recognition test, based on the “Sniffin’ Sticks” test kit. The test was applied on two occasions at a distance of approximately two weeks from each other to a group of 108 normosmic, healthy volunteers (51 men, 57 women, age range 18-95 years). The results showed that performance decreased significantly with increasing age, particularly after the age of 60. The test-retest Pearson’s coefficient of correlation between the two repeated administrations was .90, indicating a high reliability of the task. No sex-related differences were found. These data suggest that the present odour recognition memory test may be suitable for the routine clinical assessment of olfactory performance.
