- Neurological symptoms have been observed in 80% of hospitalized people with COVID-19.
- Recent studies suggest that the virus has difficulty getting past the brain’s main line of defense, the blood-brain barrier.
- Inflammatory molecules from astrocytes underlie many neurological problems as well as brain fog.
The most recent evidence suggests that the coronavirus’s attack on the brain is multifaceted. It currently appears as though the virus attacks some brain cells directly and reduces the blood flow to some others. As a consequence of its assault on glia cells, the levels of immune molecules increase dramatically; these molecules can then cause direct harm to other brain cells.
