A stroke occurs when the blood supply to the part of the brain is suddenly interrupted (ischemic) or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding the brain cells (hemorrhagic). Generally, there are three treatment stages for stroke: prevention, therapy immediately after stroke, and post-stroke rehabilitation. Therapies to prevent stroke are based on treating an individual's underlying risk factors. This book includes within its scope the prevention, risk factors, symptoms, diagnosis, treatment, and rehabilitation of stroke. Leading-edge scientific research from throughout the world is presented.
