New research published in eBioMedicine highlights PET imaging findings that may explain lingering side effects of long COVID. The study reveals that individuals with long COVID show significantly decreased integrity of dopamine neurons, which could be linked to ongoing issues like fatigue and lack of motivation. Researchers found lower dopamine nerve terminal density in key brain regions associated with these symptoms, suggesting the effects may stem from COVID-related inflammation. The authors propose that these findings may lead to new treatment strategies focused on enhancing dopamine function, potentially using medications that impact dopamine metabolism.
