Virtual reality sickness may have undesirable consequences beyond the sickness itself. For example, Crowley (1987) argued that flight simulator sickness could discourage pilots from using flight simulators, reduce the efficiency of training through distraction and the encouragement of adaptive behaviors that are unfavorable for performance, compromise ground safety or flight safety when sick ...

[1] Bad breath is viewed as a social taboo and those affected may be stigmatized. [1] [2] People in the United States spend more than $1 billion per year on mouthwash to ...
Odorants are small molecules present in the environment that bind receptors on the surface of cells called olfactory receptor neurons (ORNs). [3] ORNs are present in the olfactory epithelium which lines the nasal cavity and are able to signal due to an internal balance of signal molecules which vary in concentration depending on the presence or absence an odorant.
Anosmia may very occasionally be an early sign of a degenerative brain disease such as Parkinson's disease and Alzheimer's disease. [22] Another specific cause of permanent loss could be from damage to olfactory receptor neurons because of use of certain types of nasal spray; i.e., those that cause vasoconstriction of the nasal microcirculation ...
Diagnosing dysosmia precisely can be difficult due to the variety of causes and symptoms. Often, patients may be unsure whether or not they are having issues with smell or taste specifically. It is important to identify whether the distortion applies to an inhaled odorant or if an odor exists without the stimulus.
