A stroke is an emergency. It is caused by an interruption or change in the brain’s blood supply, and can result in severe disability and even death. Knowing the signs and symptoms of a stroke and getting to the hospital quickly can make a significant difference in how stroke patients recover. Stroke education—from prevention, to identification and treatment—is important for everyone. Strokes may be treated by a variety of medical professionals, including emergency room physicians, neurologists, neurosurgeons and other stroke and rehabilitation experts.
