How does high blood pressure cause cerebral hemorrhage and cerebral infarction?

High blood pressure causes blood pressure to rise, causing abnormal blood circulation, and eventually causing cerebral hemorrhage and cerebral infarction, which is very serious

Human blood vessels are normally elastic and under certain pressure, but with long-term hypertension, blood vessels will slowly harden, and more and more dirt in the blood vessels will be deposited in the blood vessel walls, which will also accelerate the hardening of blood vessels.

If the pressure in the blood vessels increases, the hard and brittle blood vessels will easily burst, and the blood in the blood vessels will come out, which is cerebral hemorrhage.

The dirt in the blood vessels increases, deposited on the blood vessel walls, and some of them will be washed away by the blood flow, and flow along the blood to the peripheral blood vessels, and there will be blockage, and the blocked part of the brain tissue will have no blood**, which is cerebral infarction.

Cerebral infarction is a cerebrovascular disease of cerebral ischemia and hypoxia leading to necromalacia. The most basic pathological factor of cerebral infarction is cerebral vascular occlusion, which is caused by the formation of cerebral atherosclerotic plaques.

Atherosclerosis is the most basic cause, leading to atherosclerosis, generally accompanied by hypertension and atherosclerosis causality, diabetes and hyperlipidemia can also accelerate the progression of arteriosclerosis, cerebral embolism patients, such as long-term embolism, long-term pulmonary hypertension, lower extremity thrombosis mitral valve prolapse, heart valve pride and atrial fibrillation infection sepsis, renal syndrome, hypercoagulable state, can induce cerebral embolism.

Arteritis, such as connective tissue disease, bacterial virus, spirochetal infection and drug-induced erythrocytosis, thrombocythemia, thromboembolic thrombocytopenic purpura, diffuse vascular coagulation, intracranial carotid, intracranial artery, and vertebral artery dissection aneurysm. Some ischemic attacks may also be associated with cerebral vasospasm or microthromboembolism and antiphospholipid antibody syndrome. These induce central necrosis and necrosis of the surrounding ischemic scar band.

Brain cell death and limb hemiplegia may occur due to complete ischemia.

Intracerebral hemorrhage and cerebral infarction are more dangerous: the criterion for judging is the size of the case, because in many cases, the different areas of cerebral infarction and intracerebral hemorrhage are different. Sometimes cerebral infarction is just a small area of some lacunar cerebral infarctions, which are generally not particularly serious, but some are large-scale cerebral infarctions, so if not operated in time, it may be life-threatening.

The same goes for cerebral hemorrhage, if he is just a small cerebral hemorrhage, it will not seriously affect life, but some patients may also have a large amount of cerebral hemorrhage, which is very large, leading to cerebral herniation, which can lead to very severe symptoms and even death.

The location of the patient's lesions. In fact, there are certain non-functional areas of the brain, that is, although there are lesions in this place, it may not seriously affect the later prognosis of the patient, but there are also certain areas that belong to the functional dense area, and there is a slight injury, which may cause serious consequences. For example, once the basal ganglia, thalamus, brainstem, etc. are not damaged, such as the formation of cerebral hemorrhage or cerebral infarction, even if the area is small, it can have very serious consequences.

For example, the frontal or temporal poles, even if there is a large lesion or surgical resection, do not have a serious impact on the patient.

It may also be due to cerebral infarction, or some cardiovascular and cerebrovascular diseases, or diabetes, coronary heart disease, or some chronic diseases. Cerebral infarction is more dangerous.

Staying up late, eating too much, not exercising regularly, strenuous exercise, blood swelling. I think cerebral infarction is more dangerous because the rescue time for cerebral infarction is shorter.

Intracerebral hemorrhage and cerebral infarction, in general, are more dangerous, and may occur within 24 hours, especially within 6 hours.
