A mechanism linked to the brain damage often suffered by stroke victims has been discovered by scientists, who are now searching for drugs to block it. Strokes happen when the blood supply to part of the brain is cut off but much of the harm to survivors' memory and other cognitive function is often actually caused by "oxidative stress" in the hours and days after the blood supply resumes, the authors explain.
