Stroke

Grace Ward and Gage Napier
p. 9

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.

Causes

A stroke happens when a blood vessel that carries oxygen and nutrients to the brain is  blocked by a clot or a rupture occurs.

Symptoms

Face drooping, arm weakness, and speech difficulty are common symptoms or warning signs of a stroke.

Incidence

One out of every 20 Americans die of stroke - 130,000 people per year. One person dies of stroke every 4 minutes.

Diagnostic Tests

There are imaging, electrical, and blood flow tests to determine how the brain functions and gets its blood supply.

Prevention

To prevent a stroke, identify the risk factors, work to reduce risk factors through lifestyle changes, and learn to recognize the symptoms.

Risk Factors

Common risk factors have to do with age, heredity, sex (gender), and prior stroke history.

Treatment

It is critical to receive medical attention as quickly as possible to minimize the negative effects. Tissue plasminogen activators or surgery are treatment options.
