What are the signs of a cerebral infarction? Did you know

1. Dizziness and headache.

The disease is preceded by dizziness and headaches, which start intermittently and then become persistent, severe headaches.

The appearance of dizziness and headache symptoms is generally a sign of ischemic cerebral infarction.

If the headache is severe, or even accompanied by nausea and vomiting, it may be a manifestation of hemorrhagic cerebral infarction.

2. Transient visual impairment.

Once the disease is developed, the patient will experience a transient visual impairment. This disorder manifests as blurred vision, visual field defects, or incomplete vision.

Visual impairment usually lasts within 1 hour and slowly returns to normal. This symptom is also one of the early manifestations of cerebral infarction.

3. Drowsiness and drowsiness.

When the disease develops, people will have signs of drowsiness and drowsiness. This sign is mainly manifested by frequent yawning, which is also a sign of hypoxia in the respiratory center.

When the patient's cerebral arteriosclerosis worsens, the arterial lumen will become narrower and narrower, and cerebral ischemia will also worsen.

In these cases, 80% of patients will experience frequent yawning 5 to 10 days before the onset of ischemic infarction. Therefore, if you often yawn, you must be vigilant.

4. Language impairment and numbness of limbs.

When the disease occurs, the patient's speech is affected, and the symptoms of dysphonia and occasionally aphasia appear.

The limbs will be numb due to ischemia, making it unstable to hold things. In severe cases, there will be unexplained fainting and facial paralysis.

Cerebral infarction is a disease of brain tissue caused by hypoxia and ischemia. The age of onset of cerebral infarction is between 45 and 70 years. The mortality rate of cerebral infarction is high, and once it occurs, the rescue will be very fast, so it is necessary to seek medical attention in time before having a cerebral infarction.

What are the signs of a cerebral infarction? Let's take a look.

Patients with cerebral infarction have a brief headache before the onset of the disease, which is a precursor to cerebral infarction. After a cerebral infarction, the blood in the brain** is affected. In the event of cerebral infarction, the blood flow in the brain is not smooth, which will cause severe ischemia and hypoxia in the brain, which will cause sudden headaches.

Some patients will experience symptoms such as dizziness and vertigo. At the same time, it will be accompanied by nausea, vomiting and other symptoms.

Before cerebral infarction, most patients will have visual disturbances, such as sudden blurred vision or even sudden darkness. Sometimes there is such blindness or one eye, and there are also such symptoms. If vision is blurred in one eye, it may be due to a blockage of the ophthalmic artery that branches the internal carotid artery.

There is a problem with the vision of the eye, mainly because of the blockage of the visual center. Symptoms such as blurred vision and tinnitus usually occur.

Before cerebral infarction, drowsiness occurs in addition to symptoms such as headache, dizziness, and blurred vision. During the day, patients yawn frequently. Once you fall asleep, you will feel a strong sense of sleepiness and it will be difficult to wake up.

This is related to electrolyte imbalance in the body. Hyponatremia may also be considered. Therefore, when cerebral infarction occurs, the body will have a series of symptoms, which should be checked and ** in time.

In short, before cerebral infarction occurs, symptoms such as headache, dizziness, nausea, vomiting, blurred vision, tinnitus, and drowsiness will occur. In addition, it is possible that one limb is numb, or the face is numb. As soon as the above symptoms appear, you must be hospitalized immediately.

Usually pay more attention to the regulation of diet, pay more attention not to overwork, and maintain a good attitude, so as to effectively prevent it.

The precursors of cerebral infarction include slurred speech, poor legs and feet, dizziness, headache, and vomiting. Knowing the symptoms before the onset of cerebral infarction allows patients to be diagnosed and treated in a timely manner.

Before the onset of cerebral infarction, there will be signs in the body, such as palpitations and dizziness, it is recommended to have some insomnia and irritability, at this time, we should pay attention to observation, and check in time after finding.

There may be a sudden appearance of darkness in front of your eyes, which will recover after a few seconds, and there will be no discomfort such as nausea and vomiting. If you are worried about a cerebral infarction, you will need to go to the hospital for an examination.

Before the onset of cerebral infarction, there will be a more obvious numbness in the limbs and dizziness in the body

Timely investigation in the hospital can reduce the basic conditions of cerebral infarctionAlthough the onset of this disease is sudden, it does not mean that the formation of the disease is instantaneous, but that the poor physical activity for many years has caused related problems in the brain. For this kind of problem should be detected as soon as possible, because it is easier to go to the hospital for rescue when the disease occurs, it will undoubtedly waste more time and energy.

The body will be numb, dizzy, weak, and suddenly feel particularly suffocated in the chest, which is the precursor of cerebral infarction, and must be paid attention to.

If you usually have an inexplicable headache, blackness in front of your eyes and numbness in your hands, you should be careful of "cerebral infarction".

Now there are many people with high blood pressure, hyperlipidemia and high blood sugar, and these diseases damage the vascular endothelium to a certain extent, resulting in cerebrovascular diseases, especially the incidence of cerebral infarction is getting higher and younger. Sudden appearance of temporary darkening of both eyes or blurred vision, double vision or accompanied by vertigo, numbness (numbness) in one hand, foot or face or accompanied by limb weakness, stupid tongue when speaking, unclear speech or inability to understand the meaning of others, sudden dizziness or accompanied by nausea and vomiting, and even accompanied by palpitation, sweating, unsteady walking, etc.

1. In middle-aged and elderly people, dizziness and severe headache will occur.

2. There will be numbness in the hands.

3. I often feel blurred vision.

4. The base of the tongue suddenly becomes very stiff.

5. It is manifested as yawning, especially the reaction of hypoxia in the respiratory center. About 80% of people yawn frequently 5 to 10 days before the onset of ischemic cerebral infarction, which is an important warning sign of cerebral ischemia.

6. Such as episodic unilateral limb numbness or weakness, loss of holding objects, unexplained fainting or falling, unilateral facial paralysis.

7 refers to the fact that in the process of shaving his face, when his head is turned to one side, he suddenly feels the weakness of the arm holding the razor, and the razor falls to the ground, which can be accompanied by slurred speech at the same time, but it completely returns to normal in about 1 2 minutes. This is due to the aggravation of carotid artery stenosis when the neck is turned, resulting in insufficient blood supply to the brain and transient cerebral ischemia.

8 refers to a normal person who suddenly appears black in front of his eyes, cannot see the objects in the hall, and returns to normal in a few seconds or minutes, without nausea, dizziness, or any impairment of consciousness. This is caused by transient ischemia of the retina, suggesting that a small blood clot temporarily occludes the retinal artery and is the earliest warning sign of cerebrovascular disease.

Manifestations of increased intracranial pressure, such as headache, dizziness, nausea, vomiting, vertigo episodes, etc., may occur, and limb motor dysfunction may occur. After cerebral infarction, if the brain tissue at the infarct site happens to control the movement of one limb, including the upper and lower limbs, the limb will have motor dysfunction after cerebral infarction, the hands will be stiff or unable to walk, and the legs will not be able to move.

As for sensation, the center of human sensation is also in the brain. Cerebral infarction can cause gradual numbness of the limbs, unusual pain, and other paresthesias, of which numbness is the most common. The problem with the impaired consciousness is the degree of human arousal.

If the infarct area is relatively small, the patient can be fully awake without any problems, can speak, and we can also understand what the doctor and family mean. If the size of the cerebral infarction is large, it may cause a severe increase in intracranial pressure, affecting consciousness and leading to coma.

Somatic symptoms, hemiplegia or mild hemiplegia of the limbs, hypoesthesia, unsteady gait, limb weakness, urinary incontinence, etc. There are also some precursors in the early stages of cerebral infarction. For example, it can recover after a sudden blackening within a few seconds without nausea and vomiting, impaired consciousness, and paralysis of the limbs.

This is caused by reduced intracranial blood flow and small blood clots through the retinal arteries.

Symptoms of cerebral infarction are related to the location of the brain injury, the severity of ischemia, and the size of the ischemic vessels. Initial symptoms in patients with cerebral infarction include blurred vision, confusion, physical inactivity, slurred speech, and inability to express one's thoughts. Partial cerebral infarction can be recovered if it is timely and appropriate, but it also depends on the size and severity of the cerebral infarction and the physical fitness of the patient.

Of course, some mild cases are completely asymptomatic, i.e., asymptomatic cerebral infarction; It can manifest as ** limb paralysis or vertigo, i.e., transient ischemic attack; In severe cases, the limbs are paralyzed, and even die from acute coma. If the condition is severe enough to affect the patient's cerebral cortex, patients in the acute phase of cerebrovascular disease may have seizures, with the greatest likelihood of seizures within one day of the acute phase, whereas cerebrovascular disease with epilepsy as the first symptom is rare.

1.found that the speech was unclear and it was difficult to say smooth words, 2There will also be symptoms of crooked mouth and slanted eyes, 3

The arm is numb and weak, 4When walking, you can't achieve the balance and stability of the body, 5There are symptoms of dizziness and nausea, cerebral infarction is still very damaging to the body, and it also affects normal life, everyone should still pay attention to their physical health in life.

First of all, there will be inattention, poor sleep quality, and then uncontrolled behavior, sometimes drooling, so after such a situation, you must go to the hospital for diagnosis in time**.

There will be unclear expression, slurred speech, crooked mouth and eyes, drooling, limb stiffness, numbness, dizziness, we must pay attention to rest, pay attention to daily life, otherwise it is easy to have problems.

There will be dizziness and nausea, headache, coma, sometimes unresponsiveness, and dizziness, sometimes numbness, which are very common phenomena.
