Different Types of Stroke
Stroke is the third leading cause of death the United States and is the number one cause of adult disability. These “brain attacks” occur when blood flow to the brain is interrupted, leading to brain cell damage and death. When these cells die, the functions controlled by the affected area of the brain are lost. While some people can completely recover from a stroke if emergency care is sought immediately, over two-thirds of stroke patients experience some form of permanent disability. Read on to learn more about the different types of stroke.
- Ischemic stroke
Ischemic stroke occurs when a blood clot blocks an artery supplying blood to brain tissue in a process called ischemia . There are two types of ischemic stroke: embolic and thrombotic.
- Embolic stroke
During an embolic stroke, a blood clot forms somewhere else in the body and eventually reaches a vessel in the brain small enough to block its passage. It becomes lodged in this vessel, blocking normal blood flow and leading to cell death.
- Thrombotic stroke
This second type of ischemic stroke is caused by the buildup of fatty deposits in the brain’s blood vessels. Your body considers these deposits as injuries to the vessel and responds by forming clots. In combination with the fatty deposits, the clots will cause a blockage in one or more arteries in the brain, resulting in stroke.
- Hemorrhagic stroke
Unlike ischemic strokes, hemorrhagic strokes are caused by a breakage or tear in the vessel wall. These tears cause bleeding within the brain, interrupting the normal blood flow and damaging brain tissue.
