Strokes are a result of an inadequate blood supply to the brain. When the brain’s supply of blood and oxygen is interrupted or reduced the brain cells will begin to die and a stroke will result. There are three main kinds of strokes.
Ischemic strokes are generally caused by blood clots creating blockage in the brain’s arteries. The second type of stroke, hemorrhagic stroke, happens as a result of bursting or leaking arteries in the brain. Transient ischemic attacks are a temporary reduction in blood flow that is often caused by blood clots or debris. There are several different causes for the reduction in blood flow that results in these types of strokes.
1. Cerebral Thrombosis
Cerebral thrombosis refers to blood clots which develop at a clogged part of the vessel. A cerebral thrombosis can cause full or partial blockage in the arteries of the brain.
This blockage will prevent the arteries from providing the necessary blood and resulting oxygen to the brain and can result in a stroke. A stroke which is caused by such blockage is termed ischemic. Around 80% of all total strokes are considered ischemic. Some people can be predisposed to developing these blood clots due to hypertension, certain cancers, pregnancy, lupus, or rheumatoid arthritis.
