Anosmia (loss of sense of smell) is also linked to dementia. [0] I wonder if it's a coincidence that declining vision, hearing, and smell are all linked to dementia, while the optic, vestibulocochlear, and olfactory nerves make up 3 of the 12 cranial nerves, [1] meaning they emerge directly from the brain. --- [0]: https://www.nia.nih.gov/news/loss-smell-linked-alzheimers-cognitive-impairment-and-biomarkers https://www.nia.nih.gov/news/loss-smell-linked-alzheimers-co...

Anosmia was one of the symptoms of Covid too, as I read at the time of peak Covid. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7488171/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7488171/

  Zinc deficiency is also associated with anosmia, and is also associated with dementia and Alzheimer’s. Zinc will also lower insulin via the IDE enzyme. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7883601/#:~:text=Zinc%20deficiency%20is%20well%E2%80%90known%20to%20cause%20anosmia%20and%20taste%20dysfunction.&text=During%20immune%20activation%20and%20infections,host%20defenses%20against%20invading%20pathogens https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7883601/#:~:tex.... https://alzres.biomedcentral.com/articles/10.1186/s13195-021-00931-3#:~:text=Additionally%2C%20many%20human%20studies%20have,poorer%20cognitive%20performance%20%5B12%5D https://alzres.biomedcentral.com/articles/10.1186/s13195-021....

  It is, and it is terrible. Whatever you eat is bland and you cannot smell anything.
