COVID-19 Infection and Neuropathological Features.

Area of Science:

• Pathology
• Neurology
• Infectious Diseases

Background:

• COVID-19 pathology includes acute airway inflammation and diffuse alveolar damage, similar to SARS-CoV and MERS-CoV.
• Neuropathologies in COVID-19 are increasingly noted but not fully understood.
• Understanding COVID-19's neurological impact is crucial for public health.

Purpose of the Study:

• To discuss potential mechanisms of neuroinflammation in COVID-19.
• To highlight the importance of studying COVID-19 related neuropathology.
• To explore the link between systemic infection and neurological effects.

Main Methods:

• Literature review and synthesis of existing research on COVID-19 pathology.
• Analysis of postmortem findings in COVID-19 patients.
• Discussion of proposed pathways for viral entry into the central nervous system.
• Review of the role of cytokine storm in neurological complications.

Main Results:

• COVID-19 shares respiratory pathology similarities with SARS-CoV and MERS-CoV.
• Evidence suggests potential direct viral neuroinvasion.
• Systemic inflammation and cytokine release are implicated in neurological symptoms.

Conclusions:

• Neuroinflammation is a significant concern in COVID-19.
• Direct viral invasion and/or cytokine storm are likely triggers for neuroinflammation.
• Further research is essential to elucidate the full spectrum of COVID-19 neuropathology.
