Types of Stroke

A stroke happens when blood does not flow properly into a certain part of the brain. Without fresh blood, the brain cells expire causing brain damage. When this happens, the abilities connected to the area where the brain cells died will be affected. Blood flow can be interrupted when an artery (blood vessel connected to the heart) is blocked by a blood clot. A stroke can also occur when a blood vessel in the brain ruptures causing blood to leak into the brain tissues around the area. There are two main types of stroke: Ischemic and Hemorrhagic stroke.

Ischemic stroke

Ischemic Stroke is the number one type of stroke in the United States and other parts of the globe. This stroke is caused by blood clots hindering the passage of blood in the arteries due to plaque and fatty deposits that continually build-up on the arterial walls.

There are three Ischemic types of stroke. One is Embolic infract which happens when an embolism or blood clot (which can form anywhere in the body and travel through the bloodstream) lodges itself in a blood vessel leading to the brain. Another type is Thrombotic infract. This happens when the clot is in the artery. The clot develops overtime due to plaque buildup. The last type is Lacunar infract. An arterial blockage due to hypertension causes this type of Ischemic stroke.

Hemorrhagic stroke

Hemorrhagic stroke happens when there is a rupture of a blood vessel inside the brain, which causes blood to bleed or leak into the surrounding brain tissue. This bleeding then compresses the other blood vessels in the area. Because of this, the surrounding tissue is deprived of oxygen thereby causing a stroke. Hemorrhagic stroke generally affects a big portion of the brain. There is a high incidence of death with hemorrhagic stroke.

Ischemic and Hemorrhagic are the two main types of stroke. Knowing about the types of stroke helps you avoid this sudden and sometimes fatal medical condition. Find out more about strokes, their symptoms, causes and risk factors. More importantly, discover ways to avoid a stroke. This can save your life or that of your loved ones.
