Long Covid may not be linked to brain damage, study finds

A new study suggests that long Covid is not caused by direct viral invasion or brain damage. Researchers from the University of Gothenburg in Sweden analyzed blood and cerebrospinal fluid samples from 25 people with long Covid and found no detectable SARS-CoV-2 virus or significant differences in immune activation or brain injury markers. The findings indicate that long Covid may be a consequence of events during the acute phase of Covid-19 rather than ongoing infection or inflammation.
