The mean age of those with olfactory dysfunction was significantly higher than those without olfactory dysfunction (59.8±0.5 vs. 55.1±0.2, p < 0.0001). When there’s a fit between an environmental chemical and a receptor on an olfactory cell, the nerve cell fires a signal directly to the brain on the olfactory bulb. A link between your inner ear and your brain helps you keep your balance when you get out of bed or walk over rough ground.

Furthermore, olfactory dysfunction is associated with apathy, depression, and a lower quality of life (Cramer, Friedman, & Amick, 2010; Smeets et al., 2009). After a few minutes, odors seem 80% less powerful. The most common causes are nasal and sinus diseases: by clogging the nasal passages and inflaming the tissues that receive olfactory molecules, viral infections and allergies have an effect on our sense of smell that almost everyone has experienced at some time or another.

Vaira et al23 reported 62 cases of ‘‘chemosensory dysfunc-tion’’ without specifying whether they represented olfactory or gustatory dysfunction; as a result, the value of 62 was used in both analyses of olfactory and gustatory dysfunction. Background: Olfactory dysfunction is a common symptom during otolaryngology outpatient service. According to recent neuropathological staging concepts, impaired olfaction is assumed to indicate an early pathological process and might be associated with structural changes in the brain.

There are several terms that are used to describe the different types of smell disorders. Olfactory adaptation is unusually rapid and complete. They can occur in one or both nostrils. These observations combined with the fact that olfactory neurons project directly to the amygdala and hippocampus without a thalamic relay suggests a prominent role for olfaction in mediating hedonic experience. While it’s true that the olfactory system in humans is relatively small compared to other mammals, smell both helps us enjoy life, and protects us from toxins in the environment.
