Increasing age increases the risk for stroke. The chance of a stroke doubles for each decade of life after age 55. More than half of total stroke deaths occur among women. The carotid arteries are located in the neck and supply blood to the brain. An increase in red blood cells in the bloodstream increase the risk for stroke, because the red blood cells thicken the blood and increase the likelihood of clots.
Some research shows that lower income and lower education levels increase the risk for stroke.
Certain intravenous drug abuse increases the risk for stroke. In addition, cocaine use has been closely associated with strokes. Some risk factors, such as age and family history, cannot be changed. However, other risk factors, such as lifestyle habits, can be modified to reduce the risk for stroke. Always consult your physician for more information.
