Severe Covid infections can inflame brain’s ‘control centre’, research says

Scans of people hospitalised with Covid may explain the long-term breathlessness and fatigue some patients experience

Severe Covid infections can drive inflammation in the brain's control centre", researchers say, leading to damage that may explain the long-term breathlessness, fatigue and anxiety some patients experience.

High-resolution MRI scans of 30 people hospitalised with Covid early in the pandemic, before the introduction of vaccines, found signs of inflammation in the brainstem, a small but critical structure that governs life-sustaining bodily functions such as breathing, heart rate and blood pressure.
