What are the causes of strokes?
Strokes are caused by clots in a blood vessel in the brain. Many clots are the result of a disease of the heart. As people get older many develop what is called an arrhythmia of the heart, which causes the heart rate to not be normal and form clots inside the chambers. Clots caused by high cholesterol is also a major cause of strokes. However, the smaller blood vessels of the brain can be blocked by other factors that are caused by high blood pressure and diabetes.
