Damage to the Brain from Interuption of It’s Own Blood Supply

A stroke is somethng that can happen at any time.In 2009, 34% of people were hospitalized for a stroke younger than 65 years old. Stroke is a disease that can impair activities such as walking,talking and performing essential everyday tasks used for daily living. Ischemic, Hemmarragic, and Transient Attacks are the 3 different types of strokes that can occur in the body. Although untreatable, there are signs and symptoms to look out for to treat it before it affects the brain.

By definition a Stroke is “damage to the brain from interuption of it’s own blood supply”. About 87% of all strokes are Ischemic Strokes. This is the most common type of stroke that can occur. It occurs when a blood vessel carrying blood to the brain is blocked by a blood clot. The Ischemic Stroke can occur in 2 different ways such as the Embolic Stroke and Thrombiotic Stroke. In the Embolic Stroke a blood clot is formed somewhere throughout the body and travels to the brain. The clot will then travel to a small blood vessel inside the brain to block it. The clot will stay lodged which causes the stroke. However, a Thrombiotic is caused by a blood clot that forms inside one of the arteries supplying blood to the brain. This is often seen in people who have high cholesterol levels.

Next, a Hemmarragic stroke is less common only having about 13% of people who get it. The stroke can occur from a weakened blood vessel that ruptures and then bleeds out into the brain. The body will then compress the surrounding brain tissue. Only about 15% of strokes that occur are hemmarragic but they are responsibile for over 40% deaths. It is either a Intracerebral hemmorage which is when a blood vessel will burst inside the brain which then leaks blood into the rest of the brain. The bleeding causes the brain cells to die and stop working correctly. High blood pressure and aging are the causes. The second type subarachnoid hemmorage involves bleeding in the area between the brain and the tissue surrounding it.

The third type of stroke is Transient Ischemic Attack which is also known as having a “Mini Stroke”. It is called that because the blood supply is temporary blocked, usually for less than 5 minutes. Though it is shortened, it can put you at a greater risk for having a full blown stroke. This could indicate that their a partially blocked artery leading to the brain or a clot in the heart. It is a brief period to symptoms you would have in a stroke. Now that the three different types have been distinguished it is time to talk about the complications that can occur.

The effects will be based on which part of the brain the stroke has damaged. If it occurred in the right brain some effects would be the survivor may have a hard time processing information and decreased cognitive thinking such as poor judgement, short attention span, and short term memory loss.
