Can speech return after stroke?

A stroke is a brain injury that occurs because the brain's blood supply is interrupted. It can happen because of bleeding in or around the brain (hemorrhagic), a blood clot (thrombus) forms inside one of the brain's arteries (thrombotic stroke), or a blood clot that travels to the brain, where it blocks a brain artery (embolic stroke). If a stroke affects speech, the type of stroke and how quickly it is treated influence how quickly and how much speech will improve.
