Olfactory Adaptation. The importance of the sense of smell and taste is generally underappreciated in everyday society. 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.

Olfactory dysfunction is believed to be an early warning sign of schizophrenia and is an important endophenotypic marker. 1986, Kimmelman 1986, Leopold 1986, Schiffman 1983a, 1983b) and others have dealt with clinical olfactory assessment (Cain et al. OD patients frequently ask for training modifications in the hope of a better outcome. Chem Sens 14: 713, Jefferson M (1961) Anosmia and parosmia. Why is this so important? 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. As mentioned previously, olfactory deficit is a common clinical sign in PD, present in 70–90% of the patients, and is one of the most noticeable non-motor features of disease. First, it lends credence to the growing belief that olfactory dysfunction in the absence of other sinonasal symptoms may be indicative of COVID-19 infection. Meaning Findings from this study indicate that, in a screening setting of outpatients with no or mild to moderate symptoms of COVID-19, olfactory dysfunction and gustatory dysfunction should be systematically assessed by anamnesis and by clinical testing because their results appear to have strong diagnostic value for COVID-19.

In: Meiselman HL, Rivlin RS (eds) Clinical measurement of taste and smell. Olfactory dysfunction was defined according to the diagnostic criteria for young adults: hyposmic: SOIT score of 10–12 (2 SDs below the mean) and anosmic: SOIT score <10 (4 SDs below the mean) (Nordin et al., 1998) as the objective was to investigate age-related change in olfactory function.

Conditions related to the nose, such as nasal polyps, septal deviation, as well as surgery and injury to the nose (such as rhinoplasty) can disrupt the sense of smell. Olfactory impairment is associated with incident aMCI and progression from aMCI to AD dementia. Could 'Scratch-and-Sniff' COVID-19 Testing Work? Not only does olfaction help us detect fragrances in the air around us, but it's also important in helping us enjoy the flavors of foods. While the olfactory nerve is labeled cranial nerve number one, suggesting the importance of olfaction, in practice the sense of smell is rarely tested (even by neurologists.)
