Head Neck Surg. After the colonization of the nasopharynx, SARS-CoV-2 reaches the middle ear through the eustachian tube, leading to the subsequent damage of the chorda tympani and then to dysgeusia [, At the CNS level, a possible effect on taste could be mediated by IL-6; this cytokine, by targeting the thermo-regulatory centre in the hypothalamus during COVID-19 infections, can affect the nearby thalamus, where both the gustatory and the olfactory pathways converge [, A scientific debate is ongoing as to whether anosmia/dysosmia and ageusia/dysgeusia often precede full-blown COVID-19 disease or if they are sometimes the only symptoms; thus, they are unlikely to be the result of CNS impairment. Olfactory and gustatory dysfunction are recognized as common symptoms in patients with COVID-19, with a prevalence ranging, respectively, between 4161% and 38.249%. ; et al.

In a post-mortem study, activated microglia adjacent to neurons was found in five patients dead from COVID-19, suggesting the onset of neuronophagia in the olfactory bulb, substantia nigra, and dorsal motor nucleus of the vagal nerve [, Another plausible mechanism of SARS-CoV-2 entry into the CNS is its hematologic spread to endothelial cells of the blood-brain barrier, causing pericyte and astrocyte damages. Theres no single accepted clinical test, like an eye chart, to gauge peoples sense of smell, Reed said. It seemed fitting, in this context, that I should no longer be able to trust my senses. Olfactory sensations are mediated by numerous multigene olfactory receptors (ORs), which are members of the guanine nucleotide protein (G protein)-coupled receptors (GPCRs) superfamily and their activation induces ATP conversion into cAMP by adenylate cyclase [, These neuronal connections could explain why sensory exposure to food and food-related cues, beyond its simple hedonic value, affects the food choice, the optimum development of satiation, and the energy intake regulation [, In recent years, taste basic research has rapidly improved, and taste signaling transduction pathways are partially clarified.
