What causes a stroke? What causes a stroke

There are many causes of stroke, such as increasing age, genetic factors, high blood pressure, diabetes, hyperlipidemia, smoking, obesity, lack of exercise, persistence.

Nervousness. Wait a minute. The most important of these is high blood pressure.

First of all, high blood pressure is the most important cause of intracerebral hemorrhage. The reason is simple: if blood pressure continues to rise, there is a risk that the blood vessels in the skull will be weakened

Collapse, and then cerebral hemorrhage. Therefore, as long as the blood pressure rises, it must be taken seriously and positively**. Some people have blood pressure as high as 180

mmhg or above, because there is no uncomfortable feeling is not **, which is a very dangerous thing. Regardless of whether there are symptoms or not, as long as the blood pressure is high, it is harmful, and it should be timed**, otherwise there is a potential possibility of cerebral hemorrhage.

Secondly, high blood pressure is also a cause.

Cerebral infarction. One of the main factors. If blood pressure continues to rise, the endothelium of the cerebral blood vessels will be damaged, and the cholesterol in the blood will occur.

Take the flight. Arteries form gradually.

Atherosa plaques. If the atheroma ruptures, a secondary blood clot develops, which can lead to cerebral infarction. It can be seen from this that positive.

Prevent and treat high blood pressure.

It is also very important for the prevention of cerebral infarction.

In addition to high blood pressure, a variety of factors such as diabetes, high blood lipids, and smoking can also cause stroke. Therefore, as long as the above risk factors exist, it is necessary to intervene in time to avoid serious consequences.

Nowadays, the incidence of stroke is getting higher and higher, and the occurrence of stroke is affected by many factors, so experts remind everyone to prevent stroke in time if you want to avoid the harm of stroke, so as to avoid hemiplegia of stroke. So.

This? The following experts have given a detailed introduction to this issue.

1. Hypertension and atherosclerosis.

Data show that 93% of patients with intracerebral hemorrhage have a history of hypertension, 86% of patients with cerebral thrombosis have a history of hypertension, and 70% of patients with cerebrovascular disease have a history of atherosclerosis. Atherosclerosis is a contributing factor. Due to the impaired regulation of blood lipids in patients, sclerotic plaques accumulate more and more on the blood vessel walls for a long time, and the blood flow slows down, and eventually thrombosis gradually develops, resulting in cerebral thrombosis.

High blood pressure and arteriosclerosis occur together and are the most common strokes**.

2. Cerebrovascular diseases.

Congenital anomalies of the cerebrovascular vessels are a common cause of subarachnoid hemorrhage and intracerebral hemorrhage, inflammation of the cerebral vessels that cause ischemic stroke or hemorrhagic stroke.

3. Cardioencephalopathy, rheumatism, hypertension, coronary arteriosclerotic cardioencephalopathy and subacute bacterial endocarditis may produce mural thrombosis, and when heart failure or atrial fibrillation occurs, the embolus will fall off and flow to the cerebral artery and embolism. Cerebral embolism caused by rheumatic heart disease is not only highly prevalent, but also predisposed**.

4. Metabolic diseases such as diabetes mellitus and hyperlipidemia are closely related to cerebrovascular diseases. It has been reported that 30% to 40% of patients with cerebrovascular disease have diabetes, and the incidence of arteriosclerosis in diabetic patients is 5 times higher than that of normal people, and the time of arteriosclerosis occurs earlier than that of normal people, and the degree of arteriosclerosis is also more severe.

5. Some other metabolic diseases, diabetes and stroke are closely related. Thrombocytopenic purpura is a more common bleeding disorder that can cause hemorrhagic stroke. Sometimes a stroke can occur before leukemia is diagnosed.

Stroke, also known as cerebrovascular disease, refers to cerebral dysfunction caused by cerebrovascular disease or blood flow disorders caused by various reasons, including occlusion of blood vessel lumen, rupture of blood vessels, damage to blood vessel walls or neurological dysfunction caused by abnormal blood components. The two most common conditions of cerebral stroke are cerebral hemorrhage, the most common causes of which are hypertension, cerebral arteriosclerosis, intracranial aneurysms, vascular malformations, tumor strokes, and the use of certain anticoagulant drugs.

Another condition is stroke due to occlusion of blood vessels, which is commonly caused by atherosclerosis, embolization of various emboli in the blood, and occlusion of arterioles.

Cerebral arteriosclerosis, increased intracranial pressure, leading to the rupture of blood vessels.

1.Stroke can be caused by high blood pressure.

2.Heart disease is prone to heart failure and atrial fibrillation, which can cause blood clots to break off, which in turn can lead to stroke.

3.Abnormal development of intracranial blood vessels can lead to aneurysms, arteriovenous malformations, and stroke.

Precautions. Stroke patients may develop hemiplegia, which is not conducive to care and needs to be timely**.

2. Blood diseases such as thrombocytopenic purpura, polycythemia, leukemia, often cause hemorrhagic cerebrovascular disease. Ischemic cerebrovascular disease occurs rarely.

3. All kinds of trauma, poisoning, brain tumors, brain tumors, etc., can cause ischemic or hemorrhagic cerebrovascular disease.

4. Heart disease is one of the main causes of cerebral embolism. Rheumatism, hypertension, coronary arteriosclerotic heart disease and subacute bacterial endocarditis may produce adherent thrombus, and when heart failure or atrial fibrillation occurs, the thrombus will break off and flow to the cerebral artery and cause embolism.

5. Some inflammation can invade the meninges and cerebrovascular vessels, or invade the cerebral blood vessels alone to cause cerebral arteritis, such as purulent, tuberculous, fungal inflammation and rheumatism, etc., which can cause cerebrovascular disease. In addition, changes in temperature, changes in the environment and mood, excessive tension, fatigue, etc. are also causes of stroke. People who smoke and drink excessively will also have a significant increase in the incidence of stroke.
