Summary: The number of deaths has increased due to COVID-19 infections and uncertain neurological complications associated with the central nervous system. Spike proteins play a crucial role in the infection of brain cells by COVID-19. The virus spreads to the olfactory bulb, thalamus, and brain stem through synaptic transfer, causing intense infection. This leads to excessive inflammation and immune response, resulting in neuroinflammation and neurodegeneration complications.
