A stroke is a serious health condition which can cause lasting disability, long-term brain damage, and even death.
This condition is the leading cause of death among the American population. A stroke can occur when the flow of blood, which is rich in oxygen, to the brain is blocked, or partially blocked, or when there is a bleeding in the brain.
In both cases, the brain cells start to die and cause a permanent damage. Luckily, an early detection and treatment of a stroke can help you to reduce your brain damage, to decrease the risk of a permanent disability, and to prevent an occurrence of a future stroke.
Types of a Stroke
There are two main types of a stroke, ischemic and hemorrhagic.
- Ischemic stroke occurs when an artery which supplies oxygen-rich blood to the brain is completely or partially blocked. The most common cause of this blockage is a blood clot.
- Hemorrhagic stroke occurs when an artery in the brain leaks blood or ruptures. When this type of a stroke occurs, the blood creates a pressure on the brain, which causes a brain cell damage. The two major causes of a hemorrhagic stroke are high blood pressure and aneurysms.
People at Risk of Developing a Stroke
The people who are exposed to the risk of developing a stroke are:
- People with heart disease (or a family history of heart disease)
- People with a family history of stroke
- People with high blood pressure
- People with diabetes
- People who have already experienced a stroke
- People who smoke
- People who drink alcohol or use illicit drugs
