Stroke recovery may be boosted by new drug, animal study shows

A new drug compound can successfully speed up rehabilitation for animals recovering from stroke, according to research published in Science Thursday. If it works in humans, it could eventually extend the time for repairing some brain functions after injury.

The big picture: An estimated 1.7 million people suffer a traumatic brain injury in the U.S. every year and almost 800,000 of those are from a stroke. Strokes kill 140,000 people per year and are the leading cause of serious long-term disability, CDC says.
