COVID-19-associated cognitive impairment.Reports of neurological complications in COVID-19 patients and 'long haulier' patients whose symptoms persist after the infection clears are becoming more common, suggesting that SARS-CoV-2 (the virus that causes COVID-19) may have lasting effects on brain function.
However, it is not yet well understood how the virus leads to neurological issues."While some studies suggest that SARS-CoV-2 infects brain cells directly, others found no evidence of the virus in the brain," says Feixiong Cheng, PhD, assistant staff in Cleveland Clinic's Genomic Medicine Institute and lead author on the study.
