Causes of cerebral infarction

There are many causes of cerebral infarction, and most people are not aware of these issues. Cerebral infarction is a common brain disease in our human body, and the incidence of this disease has been increasing in recent years. The specific cause is still unclear. To put it simply, cerebral infarction means necrosis or brain softening. Cerebral infarction is a disease that causes great harm to the human body and often causes other complications.

Cerebral infarction is a relatively serious disease, which mainly affects a person's brain. Therefore, many patients with cerebral infarction are often very scared and anxious after the illness. They worry that they will die from this disease. So, let’s talk about the causes of cerebral infarction, hoping it will be helpful for the treatment of cerebral infarction.

Cerebral infarction (cerebral infarction, ischemic stroke) refers to ischemic necrosis or cerebral softening of localized brain tissue caused by cerebral blood supply disorder, ischemia, and hypoxia. Common clinical types of cerebral infarction include cerebral thrombosis, lacunar infarction, and cerebral embolism. Cerebral infarction accounts for 80% of all strokes. The diseases that are most closely related to it are: diabetes, obesity, hypertension, rheumatic heart disease, arrhythmia, dehydration due to various reasons, various arteritis, shock, and excessive and rapid drop in blood pressure.

Causes of cerebral infarction

We divide cerebral infarction into two categories according to the causes: one is cerebral infarction caused by reduced cerebral blood supply; the other is hypoxic cerebral infarction caused by no reduction in cerebral blood flow, decreased quality, and insufficient oxygen content, that is, brain hypoxia. Some people divide it into two categories: cerebral vascular obstruction and cerebral blood circulation disorder. Cerebrovascular obstruction is a cerebral infarction caused by direct or indirect formation of blood clots or external emboli blocking blood vessels due to lesions in the cerebrovascular vessels themselves; cerebral blood circulation disorder refers to a cerebral infarction caused by insufficient blood supply to the brain tissue due to various reasons on the basis of existing cerebrovascular lesions, even without primary vascular disease.

1. Cardiogenic: accounting for 60%~75%. The common cause is chronic atrial fibrillation. The main sources of emboli are rheumatic heart valvular disease, endocarditis vegetation and detachment of mural thrombus, as well as myocardial infarction, atrial myxoma, cardiac surgery, cardiac catheterization, mitral valve prolapse and calcification, congenital atrioventricular septal defect (venous paradoxical embolus), etc. 2. Non-cardiac causes: such as detachment of atherosclerotic plaques, pulmonary vein thrombosis or clots, fat embolism and air embolism during fracture or surgery, blood clots or thrombus detachment during intravascular treatment, etc.; carotid artery fibromuscular dysplasia (more common in women); lung infection, sepsis.

Cerebral infarction is a cerebrovascular disease caused by cerebral atherosclerosis, which causes damage to the vascular endothelium and narrowing of the cerebral artery lumen. Subsequently, due to various factors, local thrombosis occurs, which aggravates the arterial stenosis or completely blocks it, leading to ischemia, hypoxia, and necrosis of brain tissue, causing neurological dysfunction.

The main factors of cerebral infarction are: hypertension, coronary heart disease, diabetes, overweight and hyperlipidemia. In case of cerebral infarction, you should pay attention to maintaining a good attitude, avoid being anxious or angry, and keep your mood happy. The diet should be light. Eat more fruits and vegetables. Monitor blood pressure and check blood lipids at any time. It is recommended to eat a low-salt, low-fat, high-vitamin diet (eat more fungus), quit smoking and drinking, and take oral medication on time.

Therefore, after understanding the above introduction, most of us know the causes of cerebral infarction. There are many causes of cerebral infarction. As introduced above, the causes of cerebral infarction are generally: reduced blood supply to the brain; decreased quality of blood in the brain. These two relationships are the main causes of cerebral infarction in the human body, so I hope everyone will keep them in mind.
