Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor. [1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex.
The sense of smell should be tested individually in each nostril. [18] Many cases of congenital anosmia remain unreported and undiagnosed. Since the disorder is present from birth the individual may have little or no understanding of the sense of smell, hence is unaware of the deficit. [55] It may also lead to reduction of appetite. [56]
A decreased or distorted sense of smell therefore results in a decreased quality of life. [5] Distortions are believed to have a greater negative impact on people than the complete loss of smell because they are constantly reminded of the disorder and the distortions have a greater effect on eating habits.

In a single sniff, the human sense of smell can distinguish odors within a fraction of a second, working at a level of sensitivity that is “on par” with how our brains perceive color ...
Dysgeusia, also known as parageusia, is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity. [1] An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom.
