Stroke: Causes, Symptoms, Diagnosis and Treatment. Stroke is the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For black people, stroke is the 3rd leading cause of death. Approximately 800,000 people have a stroke each year; about one every 40 seconds. Strokes occur due to problems with the blood supply to the brain: either the blood supply is blocked or a blood vessel within the brain ruptures, causing brain tissue to die. A stroke is a medical emergency, and treatment must be sought as quickly as possible.
