Stroke is a potentially life-threatening medical problem that affects people of all races. However, African Americans are at greater risk of stroke than any other ethnic group. African Americans are twice as likely to die from stroke compared to Caucasians, according to the National Stroke Association.

A stroke occurs when blood and oxygen to brain cells are suddenly cut off. This usually occurs as a result of blood clots that block arteries, or a gradual buildup of fatty deposits that cause similar blockage (ischemic stroke). Strokes also can occur when weak spots in blood vessel walls cause the vessel to suddenly burst (hemorrhagic stroke).

Patients who experience strokes may have disabilities that range from mild, moderate to severe. More serious symptoms include paralysis, difficulty thinking and speaking, and emotional problems. In some cases, strokes can be fatal.

The risk of stroke is greater – and the recovery process is slower – in African Americans compared to white Americans, according to the National Institutes of Health. African Americans also have both a higher likelihood of stroke at an earlier age and a greater risk of overall mortality compared to whites and other racial groups.
