Coronavirus Disease 2019: Latest Data on Neuroinvasive Potential

Area of Science:

• Neurology
• Virology
• Infectious Diseases

Background:

• Coronavirus disease 2019 (COVID-19) is a global pandemic caused by SARS-CoV-2.
• Neurological complications, including encephalopathy, are increasingly reported in COVID-19 patients.
• The neuroinvasive potential of SARS-CoV-2 requires further investigation.

Purpose of the Study:

• To provide an update on the virology and neurological pathogenesis of coronaviruses.
• To discuss the neuroinvasive potential of SARS-CoV-2.
• To highlight the importance of recognizing SARS-CoV-2 as a cause of neurological symptoms.

Main Methods:

• Review of existing literature on coronavirus neuroinvasion.
• Analysis of the role of angiotensin-converting enzyme 2 (ACE2) in SARS-CoV cellular entry.
• Discussion of direct and indirect mechanisms of SARS-CoV-2-induced neurological manifestations.

Main Results:

• SARS-CoV-2 may enter the brain via hematogenous or neuronal routes.
• Angiotensin-converting enzyme 2 (ACE2) is a key receptor for SARS-CoV entry into host cells.
• SARS-CoV-2 can cause neurological symptoms through direct or indirect pathways.

Conclusions:

• Further research is needed to fully understand the impact of SARS-CoV-2 on the central nervous system.
• Clarifying neuroinvasion pathways will improve management and treatment of neurological complications.
• Healthcare professionals must be aware of SARS-CoV-2 as a potential cause of neurological illness to prevent misdiagnosis and transmission.
