What causes a stroke? What causes a stroke

Stroke is also known as "cerebrovascular accident" and is commonly known as "stroke". Stroke refers to the sudden occurrence of problems in cerebral blood vessels, blockage or rupture, resulting in brain tissue damage, also known as "acute cerebrovascular disease". There are two main types: ischemic and hemorrhagic stroke.

The most common cause of stroke is a small emboli on the inner wall of the blood vessels supplying the brain, which fall off and cause an artery to embolize, known as ischemic stroke. Malformations of cerebral vascular development, such as aneurysms and vascular malformations, are the main causes of hemorrhagic stroke. The presence of multiple risk factors, such as smoking, unhealthy diet, obesity, lack of moderate exercise, excessive alcohol consumption, and the presence of underlying medical conditions such as hypertension, atherosclerosis, carotid plaque, diabetes, and hyperlipidemia, all increase the risk of stroke.

In addition to the above**, there will also be mental stress, emotional agitation, overwork, excessive exertion, straining to defecate, and climate change, which will induce its onset.

4. Metabolic diseases.

Hello, as long as it is possible to eat all the factors inside and outside the life.

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 hemorrhage includes cerebral hemorrhage, subarachnoid hemorrhage and cerebral infarction, and hypertension is the most common cause of cerebral hemorrhage. In addition to hypertension, there are many causes of cerebral hemorrhage, such as brain tumors, vascular malformations of the brain, traumatic brain injury, hematologic diseases, and the use of certain drugs. For example, anticoagulant drugs such as warfarin and thrombolytic drugs, and the most common cause of subarachnoid hemorrhage is the formation of an aneurysm.

There are many causes of cerebral infarction, such as high blood pressure, diabetes, heart disease, long-term smoking, alcohol consumption, long-term oral contraceptives in women, and obesity. In addition, hyperhomocysteinemia has also become a risk factor for cerebral infarction.

High blood pressure, obesity, smoking, depression and other factors are common risk factors for stroke, while other factors can also cause stroke.

Causes of stroke.

1. Climate. In the study, the researchers found that the susceptibility to stroke in late autumn and early spring is related to the temperature below 0, and most of them are within 72 hours of the sudden drop in temperature. Therefore, paying attention to the weather, taking cold and medicine in time is a powerful measure to prevent stroke.

Causes of stroke.

2. Time. Surveys of stroke have also found that the incidence of stroke is as high as 79 between early morning and 12 noon. Therefore, antihypertensive and antithrombotic drugs are more effective when taken after getting up.

Causes of stroke.

3. Heredity. People with a family history of the disease have a 10-fold higher risk of stroke than those who do not. Therefore, when people prevent stroke, they must not consider whether they are at high risk of developing stroke.

Causes of stroke.

Fourth, low protein.

According to the latest data from the International Stroke Society, low albumin in plasma predicts stroke with an accuracy of 75, which is higher than that of high fibrin and high blood sugar. In terms of stroke prevention, it is more important to eat more high-protein foods such as fish, eggs and soy products than low-fat diets.

Causes of stroke.

5. Magnesium deficiency. A study in Japan found that strokes were more likely to occur in people with magnesium deficiency. Eating magnesium-containing foods such as seafood, dark vegetables and hard-shelled nuts can prevent strokes.

Stroke is generally divided into two kinds, one is cerebral hemorrhage, the other is cerebral infarction, for the cause of cerebral hemorrhage, the most common is hypertension, because long-term hypertension causes the blood vessels in the skull to become hard and brittle, when the blood pressure rises suddenly, it is easy to break through some smaller blood vessels in the skull, resulting in cerebral hemorrhage, and cerebral infarction is most common because the cerebral blood vessels become narrowed on the basis of degeneration, if the patient has hyperlipidemia at the same time, the blood viscosity is relatively high, it is easy to lead to cerebral infarction, relatively speaking, cerebral hemorrhage is more serious than cerebral infarction, the mortality rate and disability rate are higher.

There are many kinds of strokes, the most common of which is atherosclerosis, cerebrovascular diseases and heart disease, atherosclerosis is the most important factor causing stroke, the patient's blood lipid regulation is also disordered, and it will be used for a long time.

Stroke is a general term for cerebrovascular diseases in traditional Chinese medicine. There are many causes of cerebral stroke, mainly due to blood vessels, blood and blood rheology. The most common of these include arteriosclerosis and embolism of the arteries caused by hypertension, hyperglycemia and hyperlipidemia; Fluctuations in blood pressure can cause hemodynamic changes; Thrombocytosis or hemoconcentration causes abnormalities in blood composition.

In addition, diseases such as hyperhomocysteinemia are also causes of stroke.

Causes of stroke: atherosclerosis, hyperlipidemia is one of the main causes of arteriosclerosis; High blood pressure is also the main and most common cause of stroke; Congenital anomalies of cerebrovascular vessels are a common cause of subarachnoid hemorrhage and intracerebral hemorrhage; Heart disease, such as endocarditis, may cause compound thrombosis; Bradycardia may cause cerebral insufficiency.

There are many causes of stroke, which are mainly manifested in the following three aspects: 1. Atherosclerosis and hyperlipidemia, hypertension, etc., with age, the ability of the human body to remove fat decreases, and the elasticity of blood vessels gradually becomes brittle; 2. Damage to blood vessels caused by high blood pressure, as well as some blood diseases, changes in blood composition, etc.; 3. Arterial injury, thrombosis, and eventually cerebral thrombosis. If the blood pressure is too high, an aneurysm develops, leading to cerebral hemorrhage, cerebral infarction or stroke.

Symptoms such as high blood pressure, low blood pressure, anemia, cervical spondylosis, cerebral insufficiency, etc. can cause this condition.

(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.

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 has also become one of the more common diseases, especially for some elderly people with poor physical fitness, the chance of suffering from stroke is relatively higher. Many people know that the chance of having a stroke is relatively high in winter, but now in the summer, the incidence of stroke is also increasing, and this is because of the problem of frequent air conditioning.

Triggers for stroke.

First of all, people who smoke and drink alcohol for a long time have a relatively high chance of having a stroke. Because some harmful substances contained in cigarettes can cause vasospasm and contraction, which will increase blood resistance and easily cause atherosclerosis;

Alcohol has a very strong nervous stimulant effect, which is easy to increase the heart rate, increase blood pressure, increase the burden on the heart, and cause the rupture of blood vessels. Especially for patients with cardiovascular and cerebrovascular diseases such as high blood pressure, the probability of having a stroke after drinking alcohol is much higher than that of ordinary people.

Secondly, high blood pressure is regarded as one of the most dangerous factors for stroke, because the increase in blood pressure will increase the pressure of blood vessels, which will be easily damaged, and the blood vessel walls will gradually thicken and narrow, and the decrease in elasticity will directly accelerate the formation of arteriosclerosis, and if you are not careful, there is a high risk of blood vessel rupture.

In addition, diabetic patients will have some abnormal manifestations due to metabolic disorders, coupled with high blood sugar in the body for a long time, which will increase the viscosity in the blood, which will also cause great damage to blood vessels, and slow blood flow will cause platelet aggregation and lead to thrombosis and stroke.

In addition, among people who are too obese, the fat content in the blood will be relatively high, which will affect the flow of blood and accelerate the occurrence of sclerosis, so obesity is also easy to cause hypertension, diabetes and other diseases, resulting in an increased chance of stroke.

Finally, many people nowadays need to be under excessive stress, if they are not able to reduce pressure in time, it will cause endocrine imbalance, increase blood pressure, and promote the occurrence of stroke.

Ways to prevent stroke.

Many middle-aged and elderly people suffer from different degrees of three highs, for these people, the probability of stroke greatly increases, so we must actively cooperate with the doctor in life, if you find any abnormalities, you need to go to the hospital for examination in time.

If you smoke and drink for a long time, the harm to the body is very great, especially for middle-aged and elderly people. This greatly increases the risk of stroke.

The occurrence of cardiovascular and cerebrovascular diseases has a lot to do with our daily diet, for example, many people like to eat high-calorie and high-fat foods, if this is the case for a long time, it will lead to excessive obesity and the probability of suffering from cardiovascular and cerebrovascular diseases will also be greatly increased. If you want to prevent stroke, you must get rid of these bad eating habits, eat more fresh vegetables and fruits, and focus on light food.

Exercise has many benefits for the body, in the process of exercise, the blood circulation of the whole body will be accelerated, so that the toxins will be quickly eliminated from the body, reducing the chance of disease.

Stroke is a cerebrovascular accident in modern medicine, which is divided into hemorrhagic ones, such as upper cerebral hemorrhage, and ischemic ones, such as cerebral infarction, so whether they are hemorrhagic or ischemic, it has some of the most basic causes. For example, our most common three highs are hypertension, hyperlipidemia and diabetes, which will cause hardening of the patient's blood vessel wall, as well as atherosclerosis and thickening of blood vessels. The narrowing of the lumen can cause arteries to rupture easily, or blood clots can easily form, resulting in cerebrovascular accidents.

In addition, people who smoke a lot or drink too much can also cause damage to the artery walls, which can lead to stroke. Modern people are in a state of anxiety for a long time due to mental tension and high work pressure, and lack of sleep will also cause endocrine disorders or increased blood pressure. Relatively speaking, we should pay attention to the three highs of the body, and we should pay more attention to our spirit and the rhythm of life.

Caused by atherosclerosis and cerebrovascular disease, as well as heart disease.

1.Atherosclerosis is the basic disease of the disease, leading to atherosclerotic cerebral infarction, often accompanied by hypertension, and atherosclerosis are mutual cause and effect, diabetes and hyperlipidemia can also accelerate the process of atherosclerosis.

2.It is rare for patients with hematologic diseases such as polycythemia, thrombocythemia, thromboembolic thrombocytopenic purpura, diffuse intravascular coagulation, and sickle cell anemia; Cerebral amyloid angiopathy, moyamoya disease, myofibrous dysplasia, and intracranial and extracranial (carotid, intracranial, and vertebral) dissected aneurysms are rare.

3.Although some cases of cerebral infarction are confirmed by imaging examination, it is difficult to find the exact **, and the possible ** includes cerebral vasospasm, unknown microemboli, abnormal protein C and protein S in antiphospholipid antibody syndrome, antithrombin deficiency, and hypercoagulable state with incomplete release of plasminogen activator.
