What can we learn from brain autopsies in COVID-19?

Area of Science:

• Neurology
• Virology
• Pathology

Background:

• Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a global health crisis with millions of deaths.
• Extrapulmonary manifestations, particularly neurological symptoms, are increasingly observed in COVID-19 patients.
• The mechanisms behind COVID-19 neurological symptoms and potential SARS-CoV-2 neuroinvasion remain unclear.

Purpose of the Study:

• To review human autopsy findings in fatal COVID-19 cases.
• To investigate the presence of SARS-CoV-2 in human brain and olfactory tissues.
• To summarize the neuropathological consequences of SARS-CoV-2 infection.

Main Methods:

• Analysis of human autopsy data from fatal COVID-19 cases.
• Review of studies investigating SARS-CoV-2 presence in brain and olfactory tissues.
• Synthesis of neuropathological findings and clinical disease manifestations.

Main Results:

• Evidence regarding SARS-CoV-2 presence in human brain tissue is being gathered.
• Neuropathological changes associated with COVID-19 infection are being identified.
• Understanding neuroinvasion potential is crucial for managing neurological complications.

Conclusions:

• Human autopsy studies are vital for understanding COVID-19's neurological impact.
• Further research into SARS-CoV-2 neuroinvasion and neuropathology is necessary.
• Integrating neuropathological findings with clinical data will improve patient management and research direction.
