High-resolution MRI scans of 30 people hospitalized with Covid early in the pandemic found signs of inflammation in the brainstem that is crucial for regulating bodily functions.
The findings point to an immune reaction causing brainstem inflammation that correlates with long-term symptoms like breathlessness and fatigue observed in patients.
Dr Catarina Rua noted that the abnormalities in brain areas linked to breathing imply a direct impact from Covid-19 infections on long-lasting health issues.
The research raises questions about potential brainstem changes in patients with long Covid, suggesting a possible link between inflammation and their continuing symptoms.
