What is a stroke? What are the symptoms of a stroke

Stroke is a description of cerebrovascular diseases in traditional Chinese medicine, which refers to various diseases of cerebral blood vessels, including cerebral atherosclerosis, thrombosis, stenosis, occlusion, cerebral arteritis, cerebral artery injury, cerebral aneurysm, intracranial vascular malformation, cerebral arteriovenous fistula, etc., whose common feature is to cause ischemia or hemorrhagic accident of brain tissue, resulting in disability or death of patients.

Cerebrovascular disease is one of the most common and important diseases in middle-aged and elderly people, among which ischemic cerebrovascular disease accounts for a relatively high proportion of 87%. According to the cause, it can be divided into large artery atherosclerotic stroke, arteriolar stroke, cardiogenic cerebral embolism, etc., among which carotid atherosclerosis is one of the main risk factors for ischemic cerebrovascular disease, and transcranial Doppler ultrasonography can non-invasively detect the blood flow velocity of intracranial arteries, and blood flow velocity is the most sensitive direct indicator to reflect the size of the lumen. Hemorrhagic cerebrovascular disease mainly includes cerebral aneurysm rupture and hemorrhage, spontaneous cerebral hemorrhage, cerebral arteriovenous malformation, deep cerebral cavernous hemangioma and other diseases.

Stroke mainly refers to acute cerebrovascular disease, including hemorrhagic stroke and ischemic stroke, hemorrhagic stroke mainly refers to cerebral hemorrhage, but if it is traumatic intracerebral hemorrhage, it is not included in the scope of stroke. Ischemic stroke mainly includes cerebral infarction and transient ischemic attack, among them, the difference between transient ischemic attack and cerebral infarction is: transient ischemic attack and cerebral infarction symptoms are the same, can be manifested as sudden slurred speech, crooked corners of the mouth, numbness and weakness of one limb, can also be manifested as dizziness, dysphagia and double shadows, but these symptoms are transient, or reversed, the symptoms are mostly relieved within 6 hours, and generally completely relieved within 24 hours, The symptoms of cerebral infarction persist for more than 24 hours.

Stroke, also known as stroke, is divided into two types: obstruction and hemorrhage, and stroke caused by cerebral vascular blockage generally occurs in a calm state, such as waking up from sleep to find that half of the body cannot move, and the corners of the mouth are crooked......Some time before a stroke, I often yawn continuously, and my hands and feet become numb. Stroke caused by bleeding has a rapid onset, such as falling to the ground and falling unconscious while walking. It is usually found that the sooner you seek medical attention after a stroke, the better, and in general, symptomatic use in the hospital with physical exercise** is ideal.

Today I would like to share with you a simple hand movement, which can prevent stroke.

There are several causes of stroke:

1. Hypertension is the first most common cause of stroke, and long-term hypertension will lead to arteriosclerosis, which will lead to blockage or rupture of blood vessels and cause stroke.

2. Diabetes, hyperlipidemia, hyperuricemia, these are also causes of stroke.

3. Long-term smoking can also cause arteriosclerosis, which can cause stroke.

4. Heart diseases, such as arrhythmia, especially patients with atrial fibrillation, are prone to form embolus in the heart, and once the embolus falls off, it will induce stroke.

5. There are other reasons, such as being too obese, not sleeping well for a long time, and too little physical exercise, which are all risk factors for stroke. Strokes include:

1. Long-term smoking;

2. The cause of stroke is also related to age, race, and gender, and the incidence of men is relatively higher than that of women, the incidence of older people is higher than that of young people, and the incidence rate of Asians is higher than that of Westerners;

3. Vascular wall lesions;

4. Changes in hemorheology, hemodynamics and blood components;

5. Patients with hypertension, diabetes, hyperlipidemia and hyperhomocysteinemia;

6. Heart disease: especially atrial fibrillation. Stroke refers to cerebrovascular accidents, including ischemic stroke (cerebral infarction) and hemorrhagic stroke (cerebral hemorrhage), and the causes of both types of stroke are diverse.

The main causes of ischemic stroke include:

1) Athesclerosis, the plaque formed by atherosclerosis is the main factor causing vascular stenosis, the huge plaque can directly cause severe narrowing of the artery and then lead to occlusion, and the narrowing of the blood vessel will lead to a decrease in blood flow, resulting in a decrease in perfusion of the distal artery and a slowing down of blood flow, which will further form thrombosis and cause cerebral infarction; There is also a part of unstable plaque, which will lead to the destruction of the intima of blood vessels, and then form platelet aggregation locally to form thrombus, or cause the rupture of the lipid core in the plaque, these thrombis and detached plaque are carried away by the blood flow and block the distal blood vessels, forming embolism.

2) Atrial fibrillation can cause the embolus to fall off, and the embolus can be formed to move forward with the blood flow, blocking small blood vessels, and if it is blocked in the cerebral artery, cerebral infarction is formed, and this type of cerebral infarction is called cardioembolism.

3) The blood itself can also lead to the formation of blood clots due to various factors such as autoimmunity or abnormal coagulation mechanisms, resulting in stroke. In addition, there are a number of other uncommon and unexplained causes of ischemic stroke.

Causes of hemorrhagic stroke include:

1) Hypertension combined with arteriosclerosis, long-term hypertension weakens the elasticity of arteriole walls, and blood vessels are prone to rupture and bleeding when blood pressure rises suddenly.

2) Others** are less common than hypertension, including cerebral arteriovenous malformation, cerebral amyloid vascular disease, cerebral basiloid abnormal vascular network disease, cerebral arteritis, hematological diseases, thrombolysis or anticoagulation**, etc.

In summary, the causes of stroke are complex, the most common cause of ischemic stroke is atherosclerosis, and the most common cause of hemorrhagic stroke is hypertension. In the process of stroke, it is necessary to distinguish first in order to carry out targeted stroke.

Stroke is a disease characterized by sudden fainting, unconsciousness and unconsciousness, accompanied by crooked mouth, unfavorable speech, hemiplegia, or crooked mouth and hemiplegia without coma. Because of the rapid onset of the disease, the symptoms are subtle and varied, and the condition changes rapidly, which is similar to the characteristics of the number of good deeds of the wind, so it is called stroke and stroke. The incidence and mortality of the disease are relatively high, and there are often sequelae; In recent years, the incidence rate has been increasing, and the age of onset has also tended to be younger, so it is a major disease that threatens human life and quality of life.

Acute cerebrovascular diseases in Western medicine, such as cerebral infarction, cerebral hemorrhage, cerebral embolism, and subarachnoid hemorrhage, belong to this category. Western medicine divides the disease into two categories: hemorrhagic and ischemic, hypertension, arteriosclerosis, cerebrovascular malformations, and cerebral aneurysms can often lead to hemorrhagic stroke; Rheumatic heart disease, atrial fibrillation, and bacterial endocarditis often cause ischemic stroke. In addition, hyperglycemia, hyperlipidemia, abnormal blood rheology and abnormal mood fluctuations are closely related to the occurrence of this disease.

CT and magnetic resonance imaging of the brain confirm the diagnosis.

Stroke is a cerebrovascular disease, which is a symptom of neurological deficit caused by bleeding or ischemia in the cerebral blood vessels, resulting in necrosis of brain cells. Stroke includes ischemic stroke and hemorrhagic stroke, ischemic plexus stroke includes cerebral thrombosis, cerebral embolism, and transient ischemic attack; Hemorrhagic strokes include diseases such as subarachnoid hemorrhage and cerebral hemorrhage. Stroke may cause symptoms of neurological deficit depending on where it occurs.

Stroke is mainly due to internal injuries and wind evil, resulting in the reversal of qi and blood in the body, the obstruction of meridians, and the main diseases of the mouth and corners, difficulty speaking, numbness of the limbs, sudden fainting, and unconsciousness. When the patient is angry, emotionally stressed, or long-term consumption of fatty and greasy products, wind and phlegm disturbance, or overwork, deficiency and yang, or the weather suddenly becomes cold, the risk of stroke can be increased.

Stroke, also known as stroke in Western medicine, can be divided into bleeding disorders such as cerebral hemorrhage and ischemic diseases such as cerebral infarction. When the patient's blood pressure, blood lipids, and blood sugar are poorly controlled, the risk of stroke can be aggravated. Therefore, it is necessary to have regular physical examinations to monitor blood sugar and blood pressure to prevent the occurrence of stroke.

Stroke refers to a condition in which the nerves in the brain are abnormally functioning due to blockage or rupture of blood vessels in the brain. It is one of the leading causes of death among the inhabitants of our country, and this is mainly due to the following reasons:

1.Unhealthy eating habits: Poor eating habits such as high-salt diet, high-fat diet, and overeating are one of the main factors leading to stroke.

2.Irregular lifestyle: Lack of healthy exercise habits and unreasonable work and rest time in daily life are also one of the high causes of stroke.

3.Chronic diseases such as high blood pressure, diabetes, and hyperlipidemia are among the risk factors for stroke.

4.Alcohol and smoking: Drinking and smoking alcohol every day increases the risk of stroke.

5.Age factor: The risk of stroke increases with age.

6.Environmental factors: Factors such as climate, air pollution, etc., may also increase the incidence of stroke.

In summary, poor lifestyle habits and chronic diseases are the main factors that lead to stroke, so we should maintain a healthy diet and lifestyle habits to control the development of chronic diseases, and emphasize a healthy diet, moderate exercise, regular work and rest, and a healthy lifestyle.

Stroke (stroke) is a disease in which the brain is dysfunctional due to insufficient blood supply to the brain or the rupture of blood vessels, and is one of the leading causes of death for our residents. So, why is there such a high incidence of stroke?

First of all, the high incidence of stroke is closely related to poor lifestyle. With the rapid development of the economy and the improvement of living standards, people's lifestyles have undergone great changes. Bad lifestyle habits such as a high-fat and high-salt diet, lack of exercise, smoking, and alcohol abuse increase blood viscosity and thinning of blood vessel walls, thereby increasing the risk of stroke.

Secondly, the aging population is also an important cause of the high incidence of stroke. With the increase of age, the human body function declines, and the incidence of diseases such as arteriosclerosis and dyslipidemia increases, which makes the prevalence of stroke increase. According to statistics, the prevalence of stroke in people over 60 years old is several times higher than in people under 40 years old.

Again, genetic factors are also a factor in contributing to stroke. If a person has a case of stroke in their family, then the risk of the person developing stroke increases. Therefore, attention should be paid to whether there are cases of stroke in the family, and timely prevention and **.

In addition, there are some other factors that can also contribute to the occurrence of stroke, such as high blood pressure, diabetes, heart disease, etc. Not only do these diseases increase the risk of stroke, but they can also aggravate the aftermath of a stroke.

For the causes of high incidence of stroke, we should take some effective preventive measures. First of all, develop a healthy lifestyle, reduce high-fat and high-salt diets, increase exercise, quit smoking and limit alcohol, etc., to reduce the risk of stroke. Secondly, strengthen the care for the elderly, timely detect and improve chronic diseases such as hypertension and hyperlipidemia, and prevent the occurrence of stroke.

Finally, for people with a family genetic history, regular check-ups and prevention strategies should be emphasized to reduce the risk of stroke.

In summary, there are many reasons for the high incidence of stroke, including poor lifestyle, aging population, genetic factors, and other chronic diseases. In order to reduce the risk of stroke, we should take effective preventive measures, including developing a healthy lifestyle, timely chronic diseases, and strengthening the care of the elderly. At the same time, there is also a need to strengthen stroke publicity and education to raise public awareness and awareness, so as to reduce the morbidity and mortality of stroke and allow people to have healthier lives.

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 admiral thrombosis, 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.

What are the symptoms of stroke?

1. Headache: Whether it is cerebral hemorrhage or cerebral infarction, headache is very common, and it is also an important symptom and signal of stroke.

2. Vomiting: It is generally accompanied by headache, and it is also very common, and it is characterized by projectile vomiting. If you vomit coffee-colored liquid, it means that the condition is very serious.

3. Dizziness: Vertigo is also accompanied by vomiting or tinnitus, which is a relatively common symptom of stroke.

4. Paresthesia on one side of the limb and face.

5. Salivation at the corners of the mouth: The phenomenon of oblique corners of the mouth, drooling or food flowing out of the corners of the mouth should be paid enough attention.

6. Sudden visual impairment: manifested as inability to see left or right objects or visual defects, or transient blackening of the eyes or the feeling of a mosquito suddenly flying in front of the eyes.

7. Sudden slurred speech and swallowing and coughing symptoms: manifested as the patient's slurred speech, difficulty in speaking words, and choking cough when drinking water or swallowing.

8. Consciousness disorder: manifested as confusion, lack of breathing, snoring, and in severe cases, deep coma.
