Learn the Difference in Three Major Types of Stroke

Many may mistakenly think that there is only one type of stroke. In fact, there are at least three main types of strokes, which leads to the question: What types of strokes are there?

Before presenting the different types of strokes, it is important to define what a stroke is. A stroke is an immediate onset of complications that affect the brain’s blood vessels. Strokes come in many types, and these types have many causes.

3 Types of Stroke

Ischemic Stroke

Ischemic strokes are the most common. In fact, they account for about eighty percent of all strokes. Ischemic strokes are caused by blood clots that develop or end up in an artery that sends blood to the brain. The blood supply is essential in providing nutrients and oxygen to your brain cells. As the lack of oxygen progresses, brain cells lack the energy to work properly. Eventually this leads to cell death, and a terminal outcome of the stroke victim. Due to the stroke type, immediate emergency treatment is crucial if the stroke victim is to survive.

Intracerebral Hemorrhage

Intracerebral hemorrhages occur when an artery inside the brain suddenly ruptures. When this occurs, blood pours into the brain, which compresses the formations in the brain. With the onset of sudden pressure in the brain, cell damage can occur. The sudden onset of pressure can usually cause unconsciousness, or even death. The parts of the brain that are usually most affected by intracerebral hemorrhage are on the brain stem, cerebellum and basal ganglia. This pressure must be relieved as quickly as possible, and is also a life-threatening condition that requires immediate emergency medical care.

Subarchnoid Hemorrhage

Subarachnoid hemorrhages are another form of stroke that is induced by a sudden artery rupture. However, they differ in one way. Subarachnoid hemorrhages cause blood to fill the area just outside the brain, rather than intracerebral hemorrhages, that fill the inside of the brain. Because of this sudden feeling of blood in the subarachnoid space, intense headaches with vomiting and nausea often result. This stroke type also causes rapid unconsciousness, and eventually ending the life of the stroke victim.

It is quite apparent that all the above stroke types require immediate medical attention. There is a very short window of time in which to identify an individual is having a stroke and receiving the proper treatment based on the stroke types. Warning signs such as weakness of the arms, legs, or even in the face are the most common stroke symptoms displayed. Many individuals will suddenly become confused and unable to speak. They may seem out of it, or even strange. Sudden vision loss, severe headache, and trouble walking, are signs that something is very wrong. You should always call 911, if you feel that you are having these symptoms or see someone else with these stroke symptoms.
