If blood supply to the brain is interrupted (because of blockage or hemorrhage), brain cells begin to die within several minutes. This condition is called stroke. Stroke is a medical emergency and it is the second leading cause of death worldwide. Some factors increase your risk of stroke and many of them are modifiable. So stroke can be prevented if these risk factors are controlled.
By answering the following 9 questions we can calculate your relative risk of developing stroke, comparing with a person who has no exposure to the risk factors. You can also see how your risk is reduced if you are able to eliminate some risk factors.
