Question 3

-Olfactory dysfunction, or dysosmia, is a problem with the sense of smell. Technically, it is a deviation from the normal sensing and perception of odor molecules, or olfactory stimuli processing. There are several different forms of dysosmia, including anosmia (stimuli do not activate the olfactory bulb), parosmia (some odors are interpreted as other odors), and phantosmia (hallucinations of smells that are not there). Based on this information, what specific condition is indicated in a person who mistakenly perceives the smell of peppermint as the same as the smell of something that is rotten, foul, and decomposed?

Accepted Answer

A)  Dysosmia
