Why does a cerebral infarction occur?

Cerebral infarction refers to cerebral infarction, cerebral infarction is usually related to atherosclerosis, small artery occlusion, cardiogenic embolism and other reasons.

1, atherosclerosis

large artery atherosclerosis may cause arterial embolism, but also easily lead to thrombosis will block blood vessels, thus inducing cerebral infarction.

2, small artery occlusion

with hypertension may lead to vitreous change in the small arteries of the brain, diabetes may lead to microvascular lesions, the above factors may increase the probability of cerebral infarction.

3, cardiogenic embolism

with heart valve disease, myocardial infarction, atrial fibrillation and other diseases, may induce cardiogenic embolism, eventually leading to cerebral infarction.
