Stroke can be classified into two major categories: ischemic and hemorrhagic. [20] Ischemic stroke is caused by interruption of the blood supply to the brain, while hemorrhagic stroke results from the rupture of a blood vessel or an abnormal vascular structure. About 87% of stroke is ischemic, with the rest being hemorrhagic.
It is also linked to an increased risk of cardiovascular disease, heart failure, and stroke. [42] [27] Also, observational data suggest that orthostatic hypotension in middle age increases the risk of eventual dementia and reduced cognitive function. [43]
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
In pathology and anatomy the penumbra is the area surrounding an ischemic event such as thrombotic or embolic stroke.Immediately following the event, blood flow and therefore oxygen transport is reduced locally, leading to hypoxia of the cells near the location of the original insult.
