Clot-buster boosts survival, decreases disability for deadly subset of stroke

New results from a multicenter study led by Johns Hopkins show that patients who got an experimental clot-busting treatment for a particularly lethal form of stroke were not only dramatically more likely to survive but also continued to shed lingering disabilities six months later.
