There are many factors that go into whether or not you will have a stroke. The following list of risk factors, increased risk factors, and additional risk factors comes directly from the CDC (the Center for Disease Control).
Race/ethnicity. African Americans have almost two times the risk of white people of having a first stroke. Hispanic Americans and American Indian/Alaska Natives are at greater risk than whites are for having a stroke but are at less risk than African Americans. African Americans and Hispanics are more likely than whites to die after having a stroke.
Age. Stroke risk increases with age. Three-quarters of strokes occur in people ages 65 and older.
Geography. The highest U.S. death rates from stroke occur in the southeastern United States.
Gender. Men are more likely than women to have a stroke.
Certain lifestyle factors and conditions also increase the risk for stroke. The most important of these include:
High blood pressure
Heart disease (such as atrial fibrillation)
Previous stroke or transient ischemic attack
Additional risk factors include:
Overweight or obesity
Sickle cell disease
Drinking too much alcohol
Family history of stroke
Genetic conditions, such as blood-clotting or vascular disorders (for example, Factor V Leiden or CADASIL)
Certain medications (such as hormonal birth control pills)
