What is a stroke?

Stroke is the disease name of traditional Chinese medicine, and it is the general name and common name of acute cerebrovascular disease. Western medicine calls it stroke or cerebrovascular accident. It is a focal cerebral blood circulation disorder caused by arteries supplying the brain (including bilateral internal carotid arteries and vertebral arteries), which leads to disturbance of consciousness and/or focal cerebral symptoms (speech disorder, facial paralysis, limb paralysis). It is a disease with sudden syncope and unconsciousness as the main symptoms, accompanied by mouth-eye deviation, language impairment, hemiplegia or no syncope and sudden hemiplegia. Because the onset of this disease is sudden, fierce and the condition changes rapidly. Like the wind in nature, it is "fickle" and "unpredictable", which is called "stroke" by ancient physicians. The fundamental causes of stroke are hypertension and cerebral arteriosclerosis. Due to the atherosclerosis of the cerebral vascular wall, the vascular lumen narrows or an open aneurysm is formed. Under the influence of emotional excitement, mental stress, overexertion, hypertension and other incentives, blood vessels rupture or block, which interferes with cerebral blood circulation, forms some pathological changes such as brain ischemia and edema, leads to neurological dysfunction, and thus appears a series of symptoms of stroke. Once you have a stroke, your condition is usually very serious. Even if the survivors actively rescue, about half of the patients will have different degrees of sequelae, such as hemiplegia, crooked mouth, difficulty in speaking and so on.
