COVID-19’s persistent and bewildering symptom, ‘brain fog,’ has left victims with headaches, trouble focusing, and memory issues. These symptoms may persist for months, leading to the infamous long-COVID syndrome, a predicament researchers are working to understand.
Exciting new research demonstrates that the formation of ‘neuronal syncytia’ — large, multicellular structures caused by SARS-CoV-2, the COVID-19 virus— could be the culprit behind this neurological phenomenon. This discovery could shine a light on the complexities of this symptom and the virus’s broader impact on the nervous system.
