What are the symptoms before the onset of cerebral infarction?

What are the early symptoms of cerebral infarction?

1. First of all, numbness in the hands and feet is one of the early symptoms of cerebral infarction, if it happens to be an older patient, you should pay more attention to your body reaction, when there is weakness in the legs and feet and abnormal gait when walking, etc., you need to pay attention, and sometimes the abnormal increase in blood pressure is also one of the signals of cerebral infarction, but this does not mean that low blood pressure is necessarily a good thing, if the blood pressure is low, it may be prone to cerebral thrombosis.

2. Secondly, if there is sudden dizziness and headache in life, it is also a sign of cerebral infarction, sometimes suddenly dizziness or pain occurs when you get up in the morning, and sometimes this situation often occurs after taking a bath or when you are tired, you must be vigilant, because when the number of dizziness or headache is more, it is easy to increase the probability of cerebral hemorrhage or cerebral infarction.

3. Finally, what I want to popularize with everyone is numbness in the hands and feet, in the final analysis, it has a lot to do with blood vessel blockage, and when sudden aphasia or slurred speech, it is likely to represent blood vessel blockage of nerves, some people obviously do not have serious cervical spine problems but find that their fingers are numb, and dysphagia and fatigue and sleep must go to the hospital for examination in time**.

If you want to stay away from cerebral infarction, you need to start from the source**, you need to dredge the blood vessels, so that the blood flow of the blood vessels in the brain is smoother.

Before the onset of cerebral infarction, there will be some obvious symptoms, dizziness, deafness and tinnitus.

I think that the most common symptoms before cerebral infarction are sudden numbness of the limbs or convulsions of the mouth and mouth, which seems to be a common symptom.

The symptoms of early cerebral infarction are as follows:

1. Dizziness, sudden aggravation of headache or change from intermittent headache to persistent severe headache It is generally believed that headache and dizziness are mostly precursors of ischemic cerebral infarction, while severe headache accompanied by nausea and vomiting are mostly precursors of hemorrhagic cerebral infarction.

2. Transient visual impairment, manifested as blurred vision, visual field defects, incomplete vision, this phenomenon mostly recovers within one hour, and is an early predictive signal of cerebral infarction.

3. Language and mental changes, referring to difficulty in pronunciation, aphasia, and writing; Sudden change in personality, taciturnity, apathy or impatience, irritability, or transient judgment or intellectual disability, lethargy.

4. Drowsiness and drowsiness, manifested by yawning, which is a reaction to cerebral hypoxia, especially respiratory center hypoxia. As cerebral arteriosclerosis worsens, the lumen of the arteries becomes narrower and narrower, cerebral ischemia worsens severely, and about 80 people yawn frequently 5 to 10 days before the onset of ischemic cerebral infarction.

What are the symptoms of the precursors of cerebral infarction.

Hello! The early symptoms of patients with cerebral infarction include headache, dizziness, tinnitus, hemiplegia, which can be a single limb or one limb, the upper limb can be heavier than the lower limb or the lower limb is heavier than the upper limb, and there are dysphagia, slurred speech, nausea, vomiting and other conditions, and severe cases quickly fall unconscious.

Cerebral infarction is an ischemic stroke, and the main symptoms that may occur are dizziness, headache, and accompanied by a malignant increase in blood pressure, and the drop in blood pressure after the use of antihypertensive drugs is not obvious.

The onset of cerebral infarction is acute, most patients are active canopy, and a very small number of patients have precursors, mainly manifested as local focal nerve dysfunction, such as transient dizziness, etc., as follows:

1.Sudden numbness and weakness of one limb, inability to pick up things, unsteady walking and easy to fall;

2.Sudden crooked facial corners, drooling, slurred speech;

3.Inability to concentrate, blurred or unable to see;

4.difficulty swallowing, easy to choke when drinking water;

5.sudden dizziness, nausea, vomiting, memory loss;

6.Sudden incontinence and unconscious.

When one or more of the above symptoms appear, even if the chain lasts for a short time, do not ignore it, please consult the emergency Zheng Shi clinic or neurology department in time to improve the relevant examinations, clarify the diagnosis, and avoid delays**.

Brief visual impairment that returns to normal in a matter of seconds. Well, the vision is incomplete.

Four: numbness or weakness of the limbs, this phenomenon can mostly recover on its own.

When the above phenomenon occurs、Nausea: a sudden change in personality, a. Third, there is neither dizziness nor impaired consciousness, and the patient should pay attention to it. Headaches are usually present, and some even ignore these initial symptoms, which is the earliest warning of cerebrovascular disease

Most patients with cerebral infarction have high blood pressure, unexplained fainting or falling, dizziness, and loss of holding objects. In terms of speech, the patient's sudden aphasia and dizziness are mostly the precursors of ischemic cerebral infarction, but many patients do not pay attention to it, and often ignore it, thinking that it is caused by poor blood pressure control, dizziness, and should go to the hospital for examination and acceptance in time**: refers to the sudden appearance of blackness in front of the eyes of normal people, indicating that cerebral infarction may occur Many patients with cerebral infarction have symptoms, somatosensory and motor abnormalities in the early stage of the disease.

Second, we must not ignore these initial symptoms, which are early warning signs of cerebral infarction.

5. Changes in mind and language, which are caused by transient ischemia of the retina, transient black lemon, should be noted: manifested as blurred vision. In fact, when the symptoms are detected at an early stage, these early symptoms are beneficial.

Cerebral infarction and recovery and pronunciation difficulties, such as the previous cheerful suddenly become silent, or visual field defects, are conducive to prognosis and can be early**.

The early signs of cerebral infarction include transient hemiparalysis of the limbs, hemisensory numbness, some patients may have unilateral eye blackness or blindness, and some patients may have episodic dizziness, nausea, vomiting and other symptoms. In addition, episodic dysphagia, dysarthria, balance disorder, and consciousness disorder are also one of the precursor symptoms of cerebral infarction. Some patients may suddenly present with episodic weakness of both lower limbs and fall to the ground, and then stand up on their own, and be conscious throughout the process.

Some patients may present with transient global amnesia, transient memory loss, and disorientation in time and space.

There are many types of brain diseases, cerebral infarction is one of them, the probability of occurrence in middle-aged and elderly people is higher, there are some signs before the onset of cerebral infarction, such as dizziness, headache, transient visual impairment, language and mental changes, drowsiness, somatosensory abnormalities, etc., after understanding clearly, take preventive measures, do not let the disease attack.

No matter what disease will have some undesirable symptoms in the early stage, before the onset of the disease, if it can be effectively inhibited, it can reduce the adverse effects on the body, cerebral infarction is one of the more serious brain diseases, easy to cause great harm to the patient's health, the following will introduce to you what is the precursor of cerebral infarction.

1. Headache and dizziness aggravate.

If the symptoms of dizziness and headache suddenly become severe, or if the symptoms of severe headache or intermittent headache are persistent, it may be caused by ischemic cerebral infarction, and severe pain accompanied by vomiting and nausea may be a precursor to hemorrhagic cerebral infarction.

2. Transient visual impairment.

Patients will have symptoms such as visual field defects and blurred things, and they can see things clearly, and they can slowly recover within about an hour, which is also a sign of cerebral infarction.

3. Abnormal language and spirit.

Speaking clearly, even unable to speak, writing becomes very difficult, expression is indifferent, personality is impatient or taciturn, personality changes suddenly, intellectual disability and judgment errors may occur in a short period of time.

4. Drowsiness. Usually always yawn, there will be respiratory center hypoxia manifestations, the disease continues to worsen, the arterial lumen is getting narrower and narrower, so it will make the brain ischemia serious, about 5 to 10 days before the onset of cerebral infarction, the symptoms of yawning are very obvious, must not ignore this sign.

5. Physical abnormalities.

There may be numbness on one side of the body, inability to hold things in the hand, no strength, fall or faint for no reason, and facial paralysis on one side of the face, which may last for about 24 hours, and many patients will have ischemic cerebral infarction about 3 to 5 years after this symptom appears.

6. The razor falls to the ground.

When shaving, when the head is turned inside, the arm will suddenly lose strength, the razor can't hold and fall to the ground, there may be a phenomenon of unclear speech, and it can return to normal after 1 2 minutes, which is due to the rotation of the neck, the narrowness of the back of the neck increases, and the cerebral blood supply is insufficient.

7. Blackness in front of the eyes.

Normal people suddenly have black eyes and can't see the objects in front of them clearly, and recover in about a few seconds or minutes, without any dizziness, nausea or consciousness disorder, which is caused by ischemia in the retina in a short period of time, and is also a precursor to cerebral infarction.

Fingers numb, tongue numbness, walking uncoordinated, my husband is a heart attack, cerebral infarction, the beginning is the hand, and finally serious walking unsteady tongue numbness, I hope it will help you.

Patients with cerebral infarction often have preceded symptoms of aura, and the common symptoms are as follows:

1. Dizziness: unsteady walking, walking to one side, which is a precursor to posterior circulatory infarction;

2. Slurred speech: slurred speech, which is generally a precursor to infarction in the dominant hemisphere;

3. Loss of consciousness: some patients will have blackness in front of their eyes and temporary loss of consciousness, most of them have problems with the internal carotid artery;

4. Paresthesia: some patients will have numbness in the hands, feet or face, often infarction of a part of the spinothalamic tract;

5. Other symptoms: Some patients will feel that their limbs are suddenly weak, or they will have strength after a while, which is a sign of pyramidal tract damage, and some patients will have headache, nausea, vomiting, and accompanied by an increase in blood pressure.

In the acute stage of cerebral infarction, once the brain cells are ischemic and hypoxic, they will send a distress signal to the body. A large amount of norepinephrine will be secreted in the body, and once norepinephrine increases, it will contract the peripheral blood vessels by increasing the heart rate, and through these ways, the blood pressure will rise rapidly, and the cells in the ischemic and hypoxic parts will be shared, which is a kind of self-help of the body. Once the above symptoms appear, you must rush to the hospital to receive a regular **.

Signs before cerebral infarction include numbness of limbs, slurred speech, dizziness, blurred vision, etc., if the symptoms are severe, it is still necessary to seek medical attention in time to avoid aggravating the condition.

Signs before cerebral infarction:

1.Limb numbness: Mainly because of the infarction of the pyramid or thalamus, it is easy to cause movement disorders of the contralateral limb, which generally occurs during activities, and patients often have symptoms such as limb numbness.

2.Slurred speech: slurred speech may also be manifested before cerebral infarction, mainly because cerebral infarction usually damages the cerebral hemispheres and is easy to cause aphasia, usually showing symptoms such as slowed speech rate, slurred speech, and difficulty in pronunciation.

3.Dizziness: cerebral arteriosclerosis and stenosis, resulting in poor blood circulation, causing brain blood disorders, if the location of cerebral ischemia is in the cerebellum or brainstem, patients will have dizziness and dizziness, poor limb coordination, and unstable standing.

4.Blurred vision: Blurred vision is also a common sign before cerebral infarction and may be caused by compression of the optic nerve by the site of the cerebral infarction.

Precautions for cerebral infarction:

The occurrence of cerebral infarction is mostly related to people's dietary habits, such as high-salt foods, high-sugar foods, and high-fat foods may increase the chance of cerebral infarction, so it is necessary to eat less of these foods.

What are the symptoms before the cerebral infarction

When the human body is sick, the body will have some symptoms before determining the specific **. Among all kinds of diseases in the body, when there is a problem with the brain, it should be considered the most serious. So, what are the symptoms before cerebral infarction? Let's find out together!

What are the symptoms before the cerebral infarction

Cerebral infarction is a disease with a high incidence among many diseases, and many elderly people may have some symptoms, but because these symptoms are sometimes ignored, the incidence of this disease is higher. Therefore, I will summarize for you several symptoms that may occur before cerebral infarction, and I hope you can pay attention to it.

1. Temporary vision weakening. Before the onset of cerebral infarction, patients will have temporary impairment of vision, such as blurred or impaired vision, and often cannot see clearly. However, these phenomena are temporary, and they will disappear on their own within a few hours after the appearance of this phenomenon, so many people generally think that this is an early symptom of cerebral infarction.

2. Numbness of the body. This symptom usually occurs in the patient's limbs first, and then slowly spreads to all aspects of the body, and sometimes even slurred speech, drooling, and numbness of the body may occur.

3. Dizziness. When dizziness occurs, many people think that it is caused by other causes, so this phenomenon is the most easily ignored.
