Summary

COVID-19 is known to involve the nervous system, for which three pathways have been suggested: (i) retrograde through neurons, (ii) angiotensin-converting enzyme 2 (ACE-2) expression in neurons, and (iii) hematogenous dissemination. In addition, damage to the central nervous system is mediated by an indirect effect of the virus causing a cytokine storm. In this chapter, the pathophysiologic mechanism of the involvement of nervous system in COVID-19 and also its clinical manifestations and the diagnostic and therapeutic approach to the neurologic complications is reviewed.
