A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery or the leaking or bursting of a blood vessel. A stroke can affect a survivor for the rest of their life. Byron Peterson had a stroke and now suffers from fluent aphasia. He speaks perfectly fluently, but it’s all gibberish. Ironically, it would be difficult recreate his gibberish without trying hard.
