GRIJALVA-OTERO, Israel. Role of SARS-CoV-2 neurotropism and neuroinvasion in COVID-19 patients disease severity. Gac. Méd. Méx [online]. 2020, vol.156, n.4, pp.335-339.  Epub 27-Maio-2021. ISSN 2696-1288.  https://doi.org/10.24875/gmm.m20000404.

The disease caused by the new SARS-CoV-2 coronavirus (COVID-19) spread rapidly from China to the entire world. Approximately one third of SARS-CoV-2-infected patients have neurological disorders, especially those classified as severe cases and that require mechanical ventilation. On the other hand, almost nine out of 10 patients admitted to an Intensive Care Unit could not breathe spontaneously, thus requiring invasive and non-invasive ventilatory support. So far, whether early neurological disorders such as hyposmia or anosmia, dysgeusia or ageusia, headache and vertigo are significant in the progression to the severe form of the disease or whether they are related to entry to the central nervous system via peripheral nerves has not been determined. Considering the great similarity between SARS-CoV and SARS-CoV-2, and that the severity of the condition that leads to death cannot be explained solely by lung involvement, it is important to determine whether SARS-CoV-2 potential invasion to the central nervous system is partially responsible for the severe respiratory component observed in patients with COVID-19.
