A stroke occurs when an artery in the brain becomes blocked or bursts. The
brain cells beyond the blockage or bleed are deprived of oxygen and
nutrients, so are damaged or die.Although some people make a full recovery, many stroke survivors have
lasting effects and are at risk of further strokes.Changes in small blood
vessels beyond the blockage are thought to contribute to post-stroke brain
damage.

A new study has found numerous changes in gene activity in affected small
blood vessels in the brain, that may provide targets for drug therapy to
improve recovery from stroke.
Scientists have been trying to find ways to minimize the damage following a
stroke and speed up recovery.Now, a study led by scientists from Weill
Cornell Medicine has found changes in gene activity in small blood vessels
following a stroke. The findings suggest that these changes could be
targeted with existing or future drugs to mitigate brain injury or improve
stroke recovery.
