COVID-19 Spike Mutation Linked to Brain Infection and Long-Term Effects

New research reveals a specific mutation in the SARS-CoV-2 spike protein enhances its ability to infect the central nervous system, potentially explaining neurological symptoms and long COVID.

Scientists identified a mutation in the SARS-CoV-2 spike protein that increases its infectivity in the brain.
The mutation may help explain neurological symptoms such as brain fog, loss of taste and smell, and long COVID.
Research showed that viruses with this mutation are more effective at invading brain cells than those in the lungs.
The findings suggest potential for targeted treatments to address COVID-19's neurological impacts.
The study highlights the importance of understanding how the virus adapts to different tissues in the body.
