Stroke is a disease that affects the arteries leading to and within the brain. Poor blood flow leads to cell death and resulting brain injuries. The two main types are ischemic - lack of blood flow and hemorrhagic - bleeding.
A stroke happens when a blood vessel that carries oxygen and nutrients to the brain is blocked by a clot or a rupture occurs.
Face drooping, arm weakness, and speech difficulty are common symptoms or warning signs of a stroke.
One out of every 20 Americans die of stroke - 130,000 people per year. One person dies of stroke every 4 minutes.
There are imaging, electrical, and blood flow tests to determine how the brain functions and gets its blood supply.
To prevent a stroke, identify the risk factors, work to reduce risk factors through lifestyle changes, and learn to recognize the symptoms.
Common risk factors have to do with age, heredity, sex (gender), and prior stroke history.
It is critical to receive medical attention as quickly as possible to minimize the negative effects. Tissue plasminogen activators or surgery are treatment options.
