What causes stroke? What is a stroke

Cause analysis. 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**.

Stroke, or stroke, is a disorder characterized by local neurological deficit caused by a disorder of blood circulation in the brain. The main causes of stroke are:

1) Hypertension and atherosclerosis are the main and most common causes of stroke.

2) 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.

3) Aneurysms and arteriovenous malformations caused by abnormal intracranial vascular development are common in subarachnoid hemorrhage and cerebral hemorrhage, and often rupture and hemorrhage multiple times.

4) 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.

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

6) Metabolic diseases such as diabetes mellitus and hyperlipidemia are closely related to cerebrovascular diseases.

7) All kinds of trauma, poisoning, brain tumors, brain tumors, etc., can cause ischemic or hemorrhagic 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.

If the questioner has a problem, it is recommended to rely on the doctor's opinion.

It is recommended that you ensure that the room is well ventilated.

Question 1: Why is a stroke called a stroke? Referring to the following, many patients who suffer from stroke may have doubts about the doctor's diagnosis when they are outpatient or inpatient, not because they suspect that the doctor's diagnosis was wrong, but because a disease has been given multiple diagnostic names.

For example, in an outpatient clinic or just after being admitted to the hospital, the doctor writes "stroke" or "cerebrovascular accident" on the medical record or admission notice; However, after CT and other examinations, it is possible to make a diagnosis of "hemorrhagic stroke" or "ischemic stroke". In the end, the discharge diagnosis was written as "cerebral hemorrhage" or "cerebral thrombosis". With so many names, it is simply confusing for patients and their families. Let's talk about the origin of multiple diseases.

The name of the disease "stroke" is actually the name of the diagnosis in traditional Chinese medicine, and the mention of "stroke" or "stroke" in the past is now referred to as "stroke" or "stroke". Modern medical research has found that the manifestation of "stroke" is caused by cerebral blood vessel rupture and bleeding or cerebral blood vessel blockage resulting in cerebral parenchymal ischemia, so Western medicine calls it "acute cerebrovascular disease". Because of the sudden onset of this disease, it seems that a disaster has come suddenly, so it is also called "cerebrovascular accident".

Therefore, the so-called "stroke" or "cerebrovascular accident" is a general term for "acute cerebrovascular disease". Cerebrovascular accidents can be divided into two categories: hemorrhagic and ischemic, the former including cerebral hemorrhage and subarachnoid hemorrhage; The latter include transient ischemic attack, cerebral thrombosis, and cerebral embolism, of which cerebral thrombosis is the most common. Intracerebral hemorrhage, cerebral thrombosis, and transient ischemic attack are most caused by hypertension and arteriosclerosis; Subarachnoid hemorrhage is mostly caused by cerebral aneurysm and bloody hand trace tube malformation; Cerebral embolism is more common in young and middle-aged patients with heart disease, such as heart valve disease, myocardial infarction, embolus detachment and blockage of cerebral blood vessels.

Question 2: What is the matter with stroke and cerebrovascular disease This has to start with the understanding of stroke among doctors in China. Before the Tang and Song dynasties, it was believed that stroke was "the inner void and the evil", such as the "Jin Kui Yaolu" believed that the veins were empty, and the wind and evil were in the void of people, and the shallow and deep in the evil, and the severity of the disease was divided into the middle meridians and the middle viscera.

That is to say, it is caused by the invasion of the human body by external wind.

After the Tang and Song dynasties, it was mostly believed that it was caused by internal wind. For example, Liu Hejian advocated that "the heart is very hot", Li Dongyuan believes that "righteousness is self-empty", Zhu Danxi advocates "wet phlegm and heat", and Zhang Jingyue puts forward the view of "internal injury and damage".

It is believed that it is due to the internal wind moving the potato to take the more, the qi and blood are reversed, and it rushes straight to the brain. Regardless of the external wind or the internal wind, it is the wind evil for the trouble, because the wind evil has the characteristics of rapid onset and rapid change of the disease, and the disease occurs suddenly, the onset is sudden, "such as the arrow stone, if the speed of the storm", the clinical symptoms are different, the changes are varied and the speed of the disease, there are faint servants, convulsions, and the characteristics of the natural world "wind and good deeds and several changes" are similar, so the ancient doctors take the analogy and name it "stroke"; Because of its sudden onset, it is also called "stroke". As for the "stroke" mentioned in the "Treatise on Typhoid Fever", it is the evidence of the sun's surface deficiency in external diseases, not the stroke of cerebrovascular diseases.

1. Limb numbness: If middle-aged and elderly people suddenly have numbness in their limbs and cannot move normally in their daily life, after ruling out cervical spondylosis and diabetes, if they are accompanied by symptoms of headache, dizziness, lightheadedness, tongue swelling, or have a history of hypertension, hyperlipidemia, diabetes, arteriosclerosis, etc., they should pay special attention and need to be alert to the occurrence of stroke.

2. Unexplained falls: some elderly people have hardened the blood vessels in the brain, which can easily lead to cerebral ischemia, motor nerve failure, ataxia and balance disorders, and it is easy to fall when walking well, which is also a typical aura of stroke.

3. Prefer to sleep: Once middle-aged and elderly people find that they have unexplained drowsiness, they must pay close attention to it, which is likely to be a precursor of ischemic stroke. And everyone's mental state has also become different from before, such as becoming silent, not liking to talk or speaking more impatiently, these conditions are directly related to the transient ischemia of the brain, which is likely to be a precursor to stroke.

4. Nosebleeds: Middle-aged and elderly people who suddenly have nosebleeds may also have a stroke, and after medical observation, it is necessary to rule out trauma and inflammation. Many nosebleeds are caused by unstable blood pressure, and if left unprevented, they can increase the risk of stroke.

Stroke is a group of diseases with cerebral ischemia and hemorrhagic injury as the main clinical manifestations, also known as stroke or cerebrovascular accident, with extremely high mortality and disability rates. It is mainly divided into hemorrhagic stroke, including cerebral hemorrhage, subarachnoid hemorrhage, intraventricular hemorrhage and ischemic stroke, including cerebral infarction and cerebral thrombosis, with cerebral infarction being the most common.

Stroke is one of the most important fatal diseases in the world. The symptoms of stroke are different from the location of the stroke and the size of the lesion, and the symptoms are different, mainly including headache, whether it is cerebral hemorrhage or cerebral infarction, headache is very common, and it is also an important signal of stroke symptoms. There are also vomiting, dizziness, vertigo is mostly accompanied by vomiting or tinnitus, which is more common in the symptoms of stroke, as well as paresthesia of one limb and face, salivation at the corners of the mouth, sudden visual impairment, sudden slurred speech and swallowing and coughing and other symptoms, consciousness becomes confused, inhaled, snoring, severe patients can have a deep coma.

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.

Cerebral stroke, also known as acute cerebrovascular disease, mainly refers to cerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction, cerebral embolism and transient spasm of cerebral blood vessels. Cerebral stroke is a common and frequent disease of the elderly, and cerebral stroke is a disease with a high disability rate and a high mortality rate, which should cause us to pay great attention to it. For stroke prevention, it is more important than **, once the stroke is carried out, it is necessary to immediately go to the hospital for examination and diagnosis.

CT scans are done first to determine whether the stroke is hemorrhage or infarction, and if the diagnosis is unclear, further magnetic resonance imaging can be done to determine whether it is a cerebral infarction. According to different diseases, cerebral hemorrhage should be actively stopped, cranial pressure should be lowered, and swelling should be reduced**. In addition, if the amount of bleeding is heavy, surgical hematoma removal can be performed.

For cerebral infarction within 6 hours of the acute phase, intravascular thrombolysis can be performed, and intravenous thrombolysis is generally performed. For cases of more than 6 hours, it is generally carried out with drugs, mainly to reduce intracranial pressure, reduce swelling, reduce blood viscosity, etc. In addition, some Chinese patent medicines that invigorate blood circulation and eliminate blood stasis are also used, such as Xuesaitong, etc.

Most of these two diseases will tend to be stable through **, but the disability rate of stroke is quite high, and functional exercise should be strengthened in the later stage to prevent the decline of limb function and cause life disorders.

Cerebral stroke is a term in traditional Chinese medicine, which is equivalent to cerebral hemorrhage and cerebral infarction in Western medicine. There are many causes, the most common are high blood pressure, hyperlipidemia, diabetes, atrial fibrillation and other problems. It is especially likely to occur if these underlying conditions are not well controlled.

Secondly, it is also related to age and gender, for example, the elderly are more likely to have stroke. Of course, some bad lifestyle habits, such as smoking, alcoholism, and eating greasy food, can also lead to stroke. There is also an uncontrollable cause, which is that congenital malformations of intracranial blood vessels can also lead to stroke.

Stroke, also known as stroke, is a disease caused by damage to blood vessels.

Stroke, also known as stroke, is a disease caused by damage to blood vessels. Most of the causes are related to high blood pressure and atherosclerosis. The disease is more common in middle-aged and elderly people, and the prevention method is to have regular physical examinations and take parents to Shanghai Panorama Medical to do it, which is very experienced.

There are many causes of stroke: for example, our common three highs, namely high blood pressure, high blood lipids, high blood sugar, etc., followed by other problems such as age, unhealthy lifestyle, and carotid plaque shedding to form blood vessel blockage, resulting in insufficient blood supply to the brain, and eventually leading to stroke.

There are many factors that cause stroke, so if you don't know what the cause is, don't give medicine to the patient to avoid causing more harm.

Cerebral stroke is a group of diseases with cerebral ischemia and hemorrhagic injury symptoms as the main clinical manifestations, also known as stroke or cerebrovascular accident, with extremely high mortality and disability rates, mainly divided into hemorrhagic stroke (cerebral hemorrhage or subarachnoid hemorrhage) and ischemic stroke (cerebral infarction, cerebral thrombosis), with cerebral infarction being the most common. Stroke is one of the most important fatal diseases in the world. The mortality rate of stroke also has a tendency to increase with age, due to the lack of effective measures, it is currently believed that prevention is the best measure, therefore, strengthen the education of the risk factors and premonitory symptoms of stroke among the whole people, and only then will the effective prevention and treatment effect be obtained.
