KISSIMMEE, Fla. (AP) Like pouring Drano directly on a clog, doctors dramatically improved stroke survival by dripping a clot-dissolving drug right onto a blockage choking off the brain's blood supply. Many patients given this experimental treatment had stunning recoveries within a day, often without the speech loss and paralysis that can follow a stroke, doctors reported .

A second study found that people given the treatment were 65 percent more likely to be able to walk, talk and function normally three months after their strokes than those given standard care.
