Stroke has many causes.
The carotid arteries, leading from the heart, through the neck to the brain, supply blood with oxygen and nutrients for use by the brain. A blood clot from the heart muscle or heart values may circulate to the brain and cut off blood supply thereby causing a stroke. Stroke can result from a blood clot breaking off from the narrowed artery or from a total blockage of the artery. Certain medical conditions, such as high blood pressure or diabetes cause atherosclerosis of the small blood vessels inside the brain, also causing stroke. Some people, however, have strokes without having an identified cause.
