Clot buster? Surgery? What is the right treatment for stroke?

During an ischemic stroke, blood vessels in the brain are blocked or narrowed. During a hemorrhagic stroke, there’s bleeding into the brain. The first treatment for stroke is to potentially offer a medication called tissue plasminogen activator (TPA) that helps dissolve blood clots. This is often called a clot buster. It has to be given within 4.5 hours from when symptoms began.
