Rapid Assessment of Olfactory Sensitivity Using the "Sniffin' Sticks"

Assessment of olfactory performance is of high clinical interest in the contexts of smell loss as well as neurological diseases, and recently gained attention in obesity research. Available olfactory tests, especially for assessing olfactory sensitivity, are time-consuming and require high cognitive capacity. Therefore, we aimed to establish a short procedure for reliably testing olfactory sensitivity using a subtest of the ""Sniffin' Sticks"" battery. Evaluation criteria are test duration, validity, and test-retest reliability.
