What is a Stroke?

Simply put, a stroke is a "brain attack." It occurs when part of the body loses function due to a disruption of blood flow in the brain. When this happens, either because of blockage from buildup in the arteries or when a vessel in the brain bursts, the affected area can’t get oxygen or nutrients. This can cause a wide range of symptoms, including the following:

• Paralysis
• Vision loss
• Difficulty speaking 
• Severe headache

Without oxygen rich blood and nutrients, brain cells in the affected area begin to malfunction and die. Learn more about different types of stroke.

Stroke Symptoms

Here are a few common symptoms of stroke:

• Sudden numbness or weakness of face, arm or leg, especially on one side of the body
• Sudden confusion or trouble speaking or understanding
• Sudden difficulty seeing in one or both eyes
• Sudden trouble walking, dizziness or loss of balance or coordination
• Sudden severe headache with no known cause

Stroke Risk Factors

High blood pressure is the number one risk factor for stroke. The following also increase risk for stroke:

• Diabetes
• Family history of stroke
• Heart disease
• High cholesterol Increasing age
• Certain medications, including birth control pills, make blood clots more likely, and therefore can increase chances for a stroke.

Hemorrhagic Stroke Risks

The following can increase the risk of hemorrhagic stroke (stroke caused by bleeding in the brain):

• Alcohol use
• Bleeding disorders
• Cocaine use

What About Age and Gender?

While the risk of stroke increases with age, a stroke can occur at any age, and nearly a quarter of strokes occur in people under the age of 65. Stroke is also not just a "man's disease." Although most women are more worried about getting breast cancer than they are about a stroke, twice as many women die of stroke than of breast cancer every year. During middle age, men are more likely to have a stroke than women, but the gender ratio reverses for people 85 and older, when women are more likely to experience a stroke.

What to Do If You Suspect a Stroke
