Dr Avindra Nath spends her days surrounded by brains.
His goal: to learn all he can about how SARS-CoV-2, the virus that causes Covid-19, affects brain tissue, potentially leading to long-term symptoms of the virus.
“The involvement of the brain is quite extensive,” said Nath, a researcher at the National Institutes of Health in Bethesda, Maryland. The brains he studies come from suddenly deceased Covid-19 patients and have all been donated by family members.

This is one of many NIH projects looking to understand why some patients experience persistent symptoms, including profound fatigue, brain fog, shortness of breath, fever, and headaches weeks and months after. their acute infection.

The 30 brain samples in Nath’s lab come from Covid-19 patients aged 5 to 80. All died at home or in a long-term care facility.
The samples are analyzed using the strongest magnetic resonance …
