Oh! The loss of smell. So that what "neurological problems" means. Well, even one who would have a seasonal flu not only lose the sense of smelling, but also won't be able to sense the taste of food as he eats, and these symptoms are not a big deal, but some higher up asshole saying that one of the COVID-19 symptoms is the loss of smell. I quite remember hearing that on TV, news on YouTube, some guys and my family I talk to.
