A stroke, also known as a cerebrovascular accident or CVA, occurs when part of the brain loses its blood supply and the part of the body that the blood-deprived brain cells control stops working. This loss of blood supply can be ischemic because of lack of blood flow, or hemorrhagic because of bleeding into brain tissue.
A stroke is a medical emergency because strokes can lead to death or permanent disability, plus there are now opportunities to treat ischemic strokes but that treatment needs to be started in the first few hours after the signs of a stroke begin. The patient, family, or bystanders, should call 9-1-1 and activate emergency medical services immediately should a stroke be suspected.
A transient ischemic attack (TIA or mini-stroke) describes an ischemic stroke that is short-lived where the symptoms resolve spontaneously. This situation also requires emergency assessment to try to minimize the risk of a future stroke. By definition, a stroke would be classified as a TIA if all symptoms resolved within 24 hours.
FAST is an acronym that can help you quickly recognize the warning signs and symptoms of stroke. You can even download a FAST app from the webpage of the American Stroke Association to help you remember these signs. Use FAST to remember and recognize the following signs and symptoms of stroke:
