What is stroke

Stroke is an acute cerebrovascular disease, which is called stroke in Chinese medicine.

Stroke is mainly caused by vascular injury of central nervous system (such as infarction and hemorrhage), resulting in acute and focal neurological deficit.

Stroke can be divided into ischemic stroke and hemorrhagic stroke. Ischemic stroke is mainly caused by cerebral vascular stenosis or occlusion, such as cerebral infarction; hemorrhagic stroke is caused by cerebral vascular rupture, such as cerebral hemorrhage.

Stroke has high incidence, high disability rate, high mortality rate and high recurrence rate, which is one of the important causes of disability and death. Its symptoms include angle of mouth, hemiplegia, decreased vision, etc., and can lead to coma or even death in severe cases. Therefore, it is very important for the prevention and timely treatment of stroke.
