What Is A Stroke? Essay example
By definition, a stroke is also known as cerebrovascular accident (CVA) is the “sudden death of brain cells due to lack of oxygen”. In other words, a stroke is a form of brain attack. It is referred as a “brain attack” because it can occur or attack at any time and to anyone (for instances, kids, adults, and elders). This means that the brain is not getting enough oxygen. The reason for oxygen shortage could be because there is blockage of blood vessels that help transport oxygen to the brain. When the brain is not getting enough oxygen, brain cells will begin to die off; lead to memory loss (they might be able to remember stuff that happened a long time ago, but not what they had for lunch or breakfast).
What are the types of strokes? What causes a stroke?
There are three types of strokes: Hemorrhagic stroke, Ischemic stroke, and Transient ischemic attack. Each form of strokes has their distinct causes of that stroke. The cause for Hemorrhagic stroke is when arteries in the brain are ruptured and blood starts to leak from the artery. This leakage or damage can occur due to/if you have trauma, hypertension, and weakness of the blood vessel walls. These health issues can damage the brain cell by forming pressure on the brain cells. There are intracerebral hemorrhage and subarachnoid hemorrhage. In the intracerebral hemorrhage, the tissue in the brain is covered by a leakage in the artery of the brain cells. In the Subarachnoid hemorrhage, the space…
