Sensory adaptation, the reduction in response to a continuing stimulus, occurs in olfaction as in other senses. Olfactory dysfunction has been considered as an important determinant of neurodegeneration because it precedes other neurological symptoms during the neurodegenerative process. Recently, evidence from clinical studies has implicated Parainfluenza virus 3 as a causal agent. Nutritional counseling may be helpful since some foods and spices which are most likely to stimulate the receptors (trigeminal and olfactory chemoreceptors.). 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 this study, we elucidated the role of excessive microglial activation, an often observed phenomenon in the damaged brain, in olfactory impairment using an NPC1 … Olfactory dysfunction negatively impacts the ERC and the deafferenting of the hippocampus from olfactory inputs upregulates memory decline.
