A new treatment may be in sight for stroke patients after scientists successfully reprogrammed immune cells to replace damaged brain cells and restore brain function after stroke-like injury.

Every year, more than 795,000 people in the U.S. have a stroke, the Centers for Disease Control and Prevention estimates. Strokes occur when blood vessels in the brain become blocked, narrowed or burst and can often result in serious brain damage. This can result in reduced mobility for more than half of stroke survivors aged over 65, and it can cause permanent memory loss, cognitive impairment, and mood disorders among other complications.
