Missing a gene helps recovery from mild stroke - science news articles

Scientists have found that patients missing a gene called CCR5 recover better from mild stokes than patients having the gene.

The study looked at 446 patients recovering after stroke and discovered that individuals without this gene improved faster in walking, arm and leg control, and other types of movement. The findings were confirmed in lab animals where the gene was manipulated by researchers.

Interestingly, one year after stroke, patients missing CCR5 also scored higher in tests assessing memory, verbal function and attention. This discovery could one day lead scientist to the development of a treatment for reversing the damage induced by stroke.
