It was postulated that SARS-CoV-2, as the other coronaviruses, would show certain neurotropism, which means the viral ability to invade and live in neural tissue, or bind to the angiotensin-converting enzyme 2 (ACE2) receptor on the neuronal cells, particularly the hippocampus, thus increasing the probability of post-remission cognitive impairment [22, 23]. Here, ACE2 is linked to Cognitive impairment.
