What is a cerebrovascular accident?

Cerebrovascular accident, also known as stroke, is generally the result of blood interruption in the brain. Oxygen and glucose, often carried by blood, are essential in brain cell health. When the blood supply is interrupted, the brain cells in this part of the brain die, which often leads to the loss of brain function. There are several types of cerebrovascular accidents. These include brain thrombosis, brain bleeding, brain embolism and a transient ischemic attack (TIA).

Cerebral thrombosis occurs when the artery, the blood vessel supplementing oxygenated blood to the brain, is reduced due to greasy deposits on its walls. The accumulation of fat deposits usually takes many years and eventually leads to a complete blockage of the artery, which can lead to the gradual onset of a cerebrovascular accident. However, a blood clot or thrombus may also form on the artery, which often leads to a sudden occlusion of the blood vessel. Risk factors for brain thrombosis include diabetes, hypertension, the use of oral contraceptives and smoking. Blood usuallyIt leaks into brain tissues, causing tissue damage. This type of cerebrovascular accident is often caused by weakening on the wall of the blood vessel, which can burst when hypertension or high blood pressure occurs. Risk factors associated with brain bleeding include hypertension, chronic alcoholism and abuse of addictive substances such as cocaine use.

embolism is a blood clot that formed from other parts of the body and travels with the bloodstream to settle on smaller arteries of the brain and cause blockage. Cerebral embolisms often occur suddenly. Patients with irregular cardiac rhythms and those who have just suffered a heart attack have higher risks for brain embolism.

and TIA is a cerebrovascular accident that occurs in less than one day. The occlusion usually occurs in a small artery and affects only a smaller part of the brain, leading to less serious damage. But this is the timeThis is a serious risk factor for the occurrence of a large cerebrovascular accident, so that rapid medical intervention is often required.

symptoms of cerebrovascular accidents usually depend on the area of ​​the affected brain and the extent of the injury. These include serious headache, confusion, temporary loss of vision and kale speech. Often there is also a weakness or paralysis on one side of the body, often including arm and leg, as well as weakness on one side of the face.
