AI Article Synopsis
Article Abstract
Objective: To examine the relationship between uninasal anatomy and olfactory ability.
Design: A stepwise analysis of variance was used to regress the logarithm of the percentage of correct responses on the Odorant Confusion Matrix (a measure of olfactory ability) against the logarithm of nasal volume measurements determined from computed tomographic scans.
Participants: Nineteen patients with hyposmia whose olfactory losses were thought to be related to conductive disorders.
Results: After correcting for sex differences, a mathematical model was developed in which the volume of 6 regions of the nasal cavity, 6 first-order interactions, and 3 second-order interactions accounted for 97% of the variation in the measure of olfactory ability.
Conclusions: Increases in the size of compartments of the nasal cavity around the olfactory cleft generally increase olfactory ability. Also, anatomical differences in the nasal cavities of men and women may account, in part, for sex differences in olfactory ability.

What does it mean when the pleasant smells come and go? Correlation between UPSIT odor identification status and fluctuation of non-motor symptoms in Parkinson's disease.

Parkinson's disease (PD) is characterized by motor and non-motor symptoms, including olfactory dysfunction. Prior studies have shown that olfaction deteriorates with disease progression, however fluctuations in olfaction and related PD symptoms have been less explored. This study aimed to investigate correlations between changes in odor identification ability and PD symptoms.

Neurodegenerative diseases represent a group of disorders characterized by progressive degeneration of neurons in the central nervous system, leading to a range of cognitive, motor, and sensory impairments. In recent years, there has been growing interest in the association between neurodegenerative diseases and olfactory dysfunction (OD). Characterized by a decline in the ability to detect or identify odors, OD has been observed in various conditions, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS).

Transitive inference, the ability to establish hierarchical relationships between stimuli, is typically tested by training with premise pairs (e.g., A + B-, B + C-, C + D-, D + E-), which establishes a stimulus hierarchy (A > B > C > D > E).

Most studies on dogs' olfactory performance focused only on some individuals pre-trained for a task or on specially selected/trained detection dogs. Here, using the Natural Detection Task (NDT) that does not require training, we assessed the effect of several potential factors on the performance of a large sample of dogs (N = 527/tested, 484/analysed). Olfactory success was associated with breeds, but breed groups (selected for olfaction, cooperation, or both) were proven non-relevant, suggesting that breed-specific traits are more influential than functional breed group characteristics.

Odors are known to entertain a special link with memory: once the meaning of an odor has been learned, it naturally acts as a retrieval cue of the learning context, along with the emotions and behaviors associated with it. The existence of this link has for several years inspired the study of olfactory function in Alzheimer's disease (AD), known for the memory disorders it causes. The aim of this review is to summarize the current scientific knowledge on the almost paradoxical dual role played by odors in the management of AD, as both screening and therapeutic tools.
