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.
An intracranial hemorrhage happened when blood accumulated inside the cranial vault. According to the exact position of blood accumulation, the main types of intracranial hemorrhage are epidural hematoma, where there’s bleeding between dura mater and skull, subdural hematoma, where bleeding is within the subdural space and subarachnoid hemorrhage where the bleeding point is between the arachnoid mater and pia mater.
For cerebral hemorrhage, which happened when bleeding is located in the brain tissue. Usually it can be due to either intraparenchymal…
