Stroke remains one of the leading causes of disability and death worldwide, leaving millions of survivors with lasting impairments that affect quality of life. In recent years, researchers have been searching for treatments that not only prevent brain damage but also help repair and restore neurological function after a stroke has occurred. Now, a growing body of evidence suggests that a new intravenous (IV) therapy could be a game-changer—potentially limiting the extent of brain injury and improving recovery outcomes.
