Study finds greater severity, disability in COVID-19 strokesA University College London (UCL) and UCL Hospital study this week found that COVID-19–associated ischemic strokes—caused by an obstruction of blood vessels in the brain—are more severe and more likely to result in disability or death than non-COVID strokes are, and Asian people are especially hard-hit.Researchers in the Journal of Neurology, Neurosurgery & Psychiatry studied 86 COVID-19–positive stroke patients admitted to 13 hospitals in England and Scotland from Mar 9 to Jul 5, comparing stroke severity and outcomes with 1,384 COVID-19–negative stroke patients admitted during the same period.
