At-Home Olfactory Training

2019-07-10 20:45:34 | BioPortfolio


The purpose of this study is to determine the impact of a twice daily at-home olfactory training program with a twenty scent, essential oil-based smell test in patients with olfactory dysfunction.


This study randomizes participants to receive either a four scent or fourteen scent olfactory retraining protocol. Baseline olfaction will be tested with a currently commercially available smell test as well as an essential oil based smell test. The protocol involves twice daily retraining where the participant inhales the scent and makes a mental note of what they should be smelling. The training period is six months total with a visit at 3 months to re-assess smell function as well as at six months.

Olfactory Training in Chronic Rhinosinusitis

Persons with a loss of sense of smell, who agree to participate in this study, will be assigned to one of three groups: two groups will have smell training and the third group will not do ...

Does Olfactory Training Improve Olfaction in a Population With Normal Sense of Smell?

Awareness of the sense of smell in the western population has been low. Most people do not think about the consequences of absence of smell (anosmia). Reduction in sense of smell (hyposmia...

Legionnaires' Effect on Smell

The goal of this study is to determine whether survivors of Legionnaires' disease suffer smell loss. A quantitative olfactory test will be performed by the participants. Such testing will ...

Olfactory Training in Improving Sense of Smell After Radiation Therapy in Patients With Paranasal Sinus or Nasopharyngeal Cancer

This randomized phase I trial studies how well olfactory training works in improving sense of smell after radiation therapy in patients with paranasal sinus or nasopharyngeal cancer. Olfac...

Omega-3 Supplementation for Smell Dysfunction

Omega-3 supplementation has been shown to have neuroprotective and potentially anti-inflammatory properties in both central and peripheral nerve injuries. The investigators are studying to...

Clinical usefulness of self-rated olfactory performance - a data science-based assessment of 6000 patients.

In clinical practice, with its time constraints, a frequent conclusion is that asking about the ability to smell may suffice to detect olfactory problems. To address this question systematically, 6,04...

Retronasal olfactory function in patients with smell loss but subjectively normal flavor perception.

The human sense of smell constitutes the main part of flavor perception. Typically, patients with loss of olfactory function complain of diminished perception during eating and drinking. However, some...

Association of Smell Identification Deficit with Alzheimer's Disease Assessment Scale-Cognitive Subscale, Japanese Version Scores and Brain Atrophy in Patients with Dementia.

Olfactory dysfunction is commonly associated with Alzheimer's disease (AD) and may be related to disorder of the central olfactory processing system. In this work, therefore, we examined the relations...

Olfactory Identification among Various Subtypes of Parkinson Disease.

This study is aimed at investigating the olfactory function among different subtypes of Parkinson disease (PD) and the impact of sex on smell identification test.

Cerebellar grey matter and olfactory performance.

The role of the cerebellum in the chemical senses is still poorly understood. This voxel-based morphometry (VBM) study investigated associations between grey matter volume (GMV) in subregions of the c...

Medical and Biotech [MESH] Definitions

The 1st cranial nerve. The olfactory nerve conveys the sense of smell. It is formed by the axons of OLFACTORY RECEPTOR NEURONS which project from the olfactory epithelium (in the nasal epithelium) to the OLFACTORY BULB.

That portion of the nasal mucosa containing the sensory nerve endings for SMELL, located at the dome of each NASAL CAVITY. The yellow-brownish olfactory epithelium consists of OLFACTORY RECEPTOR NEURONS; brush cells; STEM CELLS; and the associated olfactory glands.

Traumatic injuries to the OLFACTORY NERVE. It may result in various olfactory dysfunction including a complete loss of smell.

Set of nerve fibers conducting impulses from olfactory receptors to the cerebral cortex. It includes the OLFACTORY NERVE; OLFACTORY BULB; olfactory tract, olfactory tubercle, anterior perforated substance, and olfactory cortex. The term rhinencephalon is restricted to structures in the CNS receiving fibers from the olfactory bulb.

The ability to detect scents or odors, such as the function of OLFACTORY RECEPTOR NEURONS.
