Overview
Stroke and hemorrhagic stroke
A stroke is a brain attack. It is caused when blood flow to an area of brain is cut off. Brain cells are deprived of oxygen and begin to die. After that, abilities for the brain cells in that area to memory and muscle control are lost.
There are two main kinds of strokes: ischemic stroke and hemorrhagic stroke. Ischemic stroke is the main kind of strokes and it takes up to 80% of all strokes. It is caused by a blockage of blood flow of part of the brain and therefore, results in death of parts of brain tissue. The other kind of stroke is hemorrhagic stroke, which is caused by bleeding. Hemorrhagic strokes include bleeding in the brain, called intracerebral hemorrhage and bleeding between inner and outer layers of tissue that covered the brain, called subarachnoid hemorrhage. …show more content…
For example, trauma can cause Subdural and epidural bleeding. Bleeding are caused by varies of reasons that will be discussed later in this paper. Bleeding within the brain between inner and outer layers of tissue that covered the brain cause compression of tissue from an expanding hematoma or hematomas, and thus, result in distort and injure tissue. Also, the pressure to tissue may lead to a loss of blood supply to affected tissue with resulting infarction, and the blood released by brain hemorrhage appears to have direct toxic effects on brain tissue and vasculature. Inflammation contributes to the secondary brain injury after hemorrhage.
Hemorrhagic stroke can be categorized into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Intracerebral hemorrhage happened when blood vessel than within the brain gets hurt and leaks blood into the surrounding brain tissue and thus puts pressure on the surrounding tissue. Some common causes of intracerebral hemorrhage include high blood pressure, accidental injury, bleeding disorders and deformities in blood
