Doctors replace your blood with the blood of a healthy person who’s never suffered a stroke. This blood swap lessens damage to your brain, and any neurological deficits from the stroke are nil. While there is no known single medication for stroke, the only FDA-approved treatment for ischemic strokes is tPA, or tissue plasminogen activator, which dissolves the clot and improves blood flow. However, tPA typically must be administered within three hours of the stroke.
In the study, led by Xuefang “Sophie” Ren, research assistant professor in the Department of Neuroscience, the team found that blood substitution therapy rescues the brains of mice from ischemic damage. Their article is published in Nature Communications.
