Stroke, also commonly referred to as cerebrovascular accident, is caused by the rupture or blockage of blood vessels within the skull, leading to necrosis of brain tissue and a series of symptoms. It is divided into ischemic stroke and hemorrhagic stroke. Ischemic stroke, commonly known as cerebral infarction or stroke, while hemorrhagic stroke refers to cerebral hemorrhage. Generally, ischemic strokes account for 80% of cases. Ischemic stroke is caused by blockage of blood vessels leading to necrosis of brain tissue, presenting with a series of symptoms such as hemiplegic numbness. Cerebral hemorrhage results from rupture of brain blood vessels causing damage to brain cells and symptoms of compression, and may also present with symptoms such as hemiplegic numbness. Both types can be differentiated by their symptoms, and can also be definitively diagnosed through a CT scan.
