Olfaction today has many applications not only for an individual’s life but also for the industries. Applications include food product quality control, safety and security, environmental monitoring, indoor air quality, health care, medical diagnosis, pharmaceutical purposes, and military applications. In these applications human olfaction is still the primary instrument. This is a costly proces...

Aim of the current work was to examine developmental changes in adolescents' olfactory performance and personal significance of olfaction. In the first study olfactory identification abilities of 76 participants (31 males and 45 females aged between 10 and 18 years; M = 13.8, SD = 2.3) was evaluated with the Sniffin Stick identification test, presented in a cued and in an uncued manner. Verbal ...

Smell 'sensations' are among the most mysterious of conscious experiences, and have been cited in defense of the thesis that the character of perceptual experience is independent of the physical events that seem to give rise to it. Here we review the scientific literature on olfaction, and we argue that olfaction has a distinctive profile in relation to the other modalities, on four counts: in ...

Introduction Loss of smell is involved in various neurologic and neurodegenerative diseases, such as Parkinson disease and Alzheimer disease. However, the olfactory test is usually neglected by physicians at large. Objective The aim of this study was to review the current literature about the relationship between olfactory dysfunction and neurologic and neurodegenerative diseases. Data Synthesi...

Increasing interest is being shown in the link between olfaction, a complex sensory system, and cognition, particularly in the elderly. Olfaction is known to affect cognitive abilities and mood. In this article, we consider the impairment of olfactory function due to Alzheimer disease (AD), Parkinson disease (PD) and Lewy body disease (LBD), through pathological changes in the peripheral and ce...

Recently published work and emerging research efforts have suggested that the olfactory system is intimately linked with the endocrine systems that regulate or modify energy balance. Although much attention has been focused on the parallels between taste transduction and neuroendocrine controls of digestion due to the novel discovery of taste receptors and molecular components shared by the ton...

The fruit fly, Drosophila melanogaster, is equipped with a sophisticated olfactory sensory system that permits it to recognize and discriminate hundreds of discrete odorants. The perception of these odorants is essential for the animal to identify relevant food sources and suitable sites for egg-laying. Advances in the last year have begun to define the molecular basis of this insect's discrimi...

OBJECTIVE To characterize the olfactory identification in 40 essential tremor (ET) patients, with the University of Pennsylvania 12 Smell Identification Test (UPSIT), to correlate UPSIT scores to clinical and epidemiological data and to compare it to 89 aged matched controls. METHOD Patients were assessed using ET Clinical Scale of Evaluation and UPSIT. RESULTS In patients with ET, the UPSI...

Olfactory function may be important for environmental and nutritional safety and enjoyment. Population-based epidemiological studies of olfaction are needed to understand the magnitude of the health burden, identify modifiable risk factors, and develop and test prevention and treatment strategies for olfactory impairment. However, measuring olfaction in large studies is challenging, requiring r...
