Brain imaging reveals changes linked to long COVID --British study

Brain imaging reveals changes linked to long COVID Using ultra-powered magnetic resonance imaging (MRI), researchers from the Universities of Cambridge and Oxford have demonstrated that COVID-19 infections can damage the brainstem, the brain’s "control center." The findings are published in Brain. CIDRAP

The study was based on the MRI images of 30 people who had been hospitalized with severe COVID-19 before the availability of COVID-19 vaccines. The images were captured with a 7-Tesla machine, which can measure inflammation levels in the brain. Typically, brainstems can only be imaged postmortem, but the 7-Tesla allows researchers to look at the nuclei of brainstems in living participants.
