What are the symptoms of cerebral thrombosis? What are the symptoms of cerebral thrombosis

Cerebral thrombosis, also known as atherosclerotic thrombotic cerebral infarction, is the most common type of cerebral infarction. In terms of clinical symptoms, the main clinical symptoms are: if the infarction occurs in the parietal lobe, there will be sensory impairment and limb movement disorder.

If the infarct occurs in the frontal lobe, there will be psychiatric symptoms, speech impairment, hemiplegia, urinary incontinence, and clumsiness in contralateral limb movements. If the blood clot is in the temporal lobe, memory loss, unresponsiveness, inability to understand others, self-talk, and sometimes seizures may occur. In occipital infarction, visual distortion and visual field defects may occur.

Infarction of deep brain tissue will cause the typical speech inability we often see, hemiplegia, hemiplegia, hemisensory impairment, etc. Infarction of the cerebellum presents with impaired balance, manifested by unsteadiness in standing and walking, and swaying from side to side. The clinical manifestations of brainstem infarction are diverse and ever-changing, and dizziness, visual pairing, arthria, difficulty eating, choking on drinking water, paralysis of the contralateral limb, numbness and sensory impairment may occur.

If it is a thrombus in the large arteries of the brain, the infarction area is large, the condition is severe, and the patient may have impaired consciousness, coma or even sudden death. The formation of cerebral thrombosis is the most common one of cerebrovascular diseases, which refers to the pathological changes in the arterial vascular wall of the brain tissue inside and outside the skull, and the narrowing of the vascular lumen or the formation of thrombosis on this basis, resulting in the interruption of local acute blood flow in the brain, hypoxia, ischemia, softening and necrosis of the brain tissue, and the corresponding neurological symptoms and signs, often hemiplegia and aphasia. It is characterized by paralysis of the face, tongue and limbs to varying degrees, without sensory impairment, visual field loss, aphasia, etc.

The clinical manifestations of cerebral thrombosis can vary depending on the location of the lesion. Common manifestations include limb paralysis, sensory impairment, headache, dizziness, nausea, vomiting, unsteady walking, unclear speech, choking on water, unclear vision, drowsiness, and even coma.

So what are the symptoms of cerebral thrombosis?

1. The onset of cerebral thrombosis is acute, and often begins in one upper limb, and then within a few hours.

Within one or two days, the symptoms of neurological dysfunction progressively involve other parts of the limb.

2. Many people with cerebral thrombosis do not have headache, vomiting and other symptoms of intracranial hypertension, secondary cerebral edema that occurs within a few days after the occlusion of a large artery can worsen the symptoms and lead to consciousness disorders, and severe cerebral edema can also cause the risk of fatal intracranial structural displacement (brain herniation).

3. Middle cerebral artery and its deep perforator branch: most susceptible to involvement, contralateral hemiplegia (severe), heminumbness (sensory loss), homonymous hemianopia, aphasia can be manifested when the main hemisphere (usually left) is involved, and apraxia occurs when the non-dominant hemisphere is involved.

4. Internal carotid artery: it can cause blindness in the ipsilateral eye, and other symptoms are often difficult to distinguish from the symptoms and signs that appear after the occlusion of the middle cerebral artery and its deep perforating branch.

5. Anterior cerebral artery: uncommon, one side can cause contralateral hemiplegia (heavy lower limbs, light upper limbs), strong grip reflex and urinary incontinence. Bilateral involvement can cause apathy, confusion, and occasionally mutism and spastic paraplegia.

6. Posterior cerebral artery: ipsilateral hemianopia, contralateral hemiplegia loss, spontaneous thalamic pain, or sudden involuntary hemiconvulsions; Dyslexia may be seen in the dominant hemisphere when affected.

Clinical symptoms of cerebral thrombosis depend on the location of ischemic damage to the brain tissue. Common clinical symptoms include dizziness, spinning, diplopia, aphasia, dysphagia, choking on drinking water, crooked corners of the mouth, numbness and weakness of limbs, paresthesia in most patients, and hemiplegia in severe cases. The clinical manifestations of cerebral thrombosis are complex and diverse, and imaging examinations are required to determine the location and severity of cerebral vascular blockage.

What are the symptoms of cerebral thrombosisIn fact, cerebral thrombosis is a precursor disease, not all at once it will go directly to the severity of cerebral thrombosis, if you can first grasp the corresponding symptoms in the early stage, and think of ways to effectively solve these symptoms, it should be able to avoid the later deterioration to very serious before starting. So, what are the symptoms of cerebral thrombosis?

First, you will suddenly feel very dizzy, which is a very typical type of cerebral thrombosis precursor, and generally speaking, it can occur at any time before cerebral thrombotic disease, such as morning, noon and evening. Second, there is a sudden severe headache, which may also be caused by cerebral thrombosis, and third, the pace is abnormal, for example, you can walk in a straight line normally, but you will falter when you are not drinking. Fourth, yawning constantly, that is, yawning even when you have slept a lot, and fifth, there may be very severe nosebleeds, and this nosebleeds often come suddenly without any symptoms.

The above is an analysis of the answers given around the topic of what are the symptoms of cerebral thrombosis. By sharing, everyone understands that there are some corresponding symptoms of cerebral thrombosis, if all the above symptoms are accounted for, you should focus on the possibility of cerebral thrombosis, and go to the hospital to do a detailed head CT examination to make it clear.

1 Sudden onset of vertigo. Vertigo is an extremely common symptom of precursors to cerebral thrombosis and can occur at any time before cerebrovascular disease, especially when waking up in the morning. In addition, it is also prone to occur after fatigue and bathing.

In particular, if patients with high blood pressure have more than 5 episodes of vertigo in 1 to 2 days, the risk of cerebral hemorrhage or cerebral infarction increases.

2 Sudden onset of severe headache. any sudden, severe headache; with seizures of convulsions; recent history of head trauma; with coma, drowsiness; There is a sudden change in the nature, location, distribution, etc. of the headache; headache aggravated by strained coughing; The pain is severe and you may wake up in pain during the night. If you have one of the above precursors of cerebral thrombosis, you should go to the hospital for examination as soon as possible**.

3 Gait abnormality. Staggering and weakness in the legs are one of the precursor symptoms of hemiplegia. If there is a sudden change in gait in an older person, accompanied by numbness and weakness of the limbs, it is a precursor to the development of cerebral thrombosis.

4 Yawn incessantly. In patients with ischemic cerebral thrombosis, 80% of patients will yawn 5 to 10 days before the onset of the disease.

5 Nosebleeds in hypertensive patients. This is a red flag to be aware of. Several episodes of heavy nosebleeds, coupled with fundus bleeding and hematuria, such people may develop cerebral thrombosis within six months.

6 Abnormal blood pressure. A sudden and persistent increase in blood pressure above 200 120 mmHg is a precursor to cerebral thrombosis; A sudden drop in blood pressure below 80 to 50 mmHg is a precursor to the formation of a cerebral thrombosis.

7 Other aura symptoms. In addition to the above-mentioned precursor symptoms of cerebral thrombosis, choking, difficulty swallowing, sudden numbness of half of the body, tiredness, drowsiness, tinnitus, etc. are also precursors of cerebral thrombosis.

Cerebral thrombosis is a blood vessel in the brain that is plugged, blood flow is interrupted, and brain cells die, which will cause corresponding symptoms. Because the brain is divided into many functional areas, different places are blocked, and the symptoms are different:

1. Language dysfunction: that is, we often have problems with speech, and speech problems are divided into two parts, the first is that we can't speak and can't speak clearly; The second is that you don't understand, when others communicate with him, they will answer the wrong questions, and you will feel that he is abnormal or abnormal;

2. Motor dysfunction: paralysis will occur, including facial paralysis, crooked corners of the mouth, limb paralysis may appear weakness, unstable holding objects, and inability to walk;

3. Sensory dysfunction: numbness of hands and feet, facial numbness or paresthesia, feeling that there are insects or ants walking. It must be a fixed symptom, and you can't be numb on the left side and numb on the right;

4. Visual field defect: When our eyes look straight ahead, we find that we can't see a certain range, for example, when there is a visual field defect on the right, we will touch something on the right side when we walk, that is, you don't pay attention to it. Others think that you are a person and don't look at the road, but it's not that you don't look at the road, it's because you can't see it.

For example, when you pick up the dishes, you may not be able to catch the dishes on the right table, and only the ones on the left.

A common symptom in the early stages of cerebral thrombosis.

1. Crooked mouth and eyes or drooling. For example, weakness or numbness on one side of the face, crooked mouth when smiling, or mouth holding water or even drooling when brushing teeth.

2. Hemilimb weakness, that is, "hemiplegia", can be divided into two types: upper limb weakness and lower limb weakness. Weakness of the upper limbs is manifested by the sudden feeling of weakness in the arm when shaving with a knife, causing the razor to fall to the ground; Unable to use chopsticks to pick up vegetables; You can't button up, get dressed, etc. Weakness of the lower limbs can be manifested as tilting to one side, "running off", and even "dragging legs" when walking; unsteady walking, abnormal gait; Unconscious repeated falls when walking, especially when turning and tilting heads.

In the above cases, it is necessary to pay attention to the possibility of further development of cerebral thrombosis.

3. Speaking is not good. Struggle to speak, "big tongue" or inability to understand others.

4. Blurred vision. Patients may suddenly lose sight in one eye due to occlusion of the arteries that supply blood to the eye, or damage to the center of the brain responsible for analyzing vision.

5. Sudden dizziness. This is a very common signal of cerebral thrombosis, which is manifested as dizziness, stuffiness, and even whirlwind, unstable body, uncontrollable feelings, and in severe cases, it can be accompanied by nausea, vomiting, sweating, etc. This is because there is an abnormality in the part of the brain that is responsible for coordinating the balance of the body.

6. Numbness of limbs. In particular, hemibody numbness is often a warning of cerebral thrombosis. Because the brain is responsible not only for the movement of the limbs, but also for all the senses, paresthesias are often a sign of cerebral thrombosis.

7. Sleepy, drowsy or yawning. For example, if you can fall asleep while watching your favorite TV show, you can't concentrate, yawn constantly, etc., which indicates that the blood supply to the brain is not enough to stay awake, and the arteries may be narrowed or even occluded.

8. Headache. Unexplained headache, or the original nature of the headache changes, mostly manifested as persistent pain, severe may be accompanied by nausea and vomiting.

9. Choking and difficulty swallowing. Choking cough when eating or drinking, or even difficulty swallowing, may be accompanied by slurred speech, hoarseness, etc., indicating an abnormality in the nerve or center responsible for the movement of the throat muscles.

10. Sudden memory loss and difficulty in reading and writing. Some patients will suddenly be unable to call the names of people or objects, unable to calculate or write normally, or forget things. This suggests an abnormality in the cerebral cortex, which is responsible for higher-order thinking.

The "cerebral thrombosis" often referred to in our lives refers to cerebral infarction in medicine, which is the avascular necrosis or softening of localized brain tissue caused by cerebral blood circulation disorders, ischemia and hypoxia, and the clinical symptoms are complex, and the clinical manifestations depend on the size and location of the infarct foci and the blood supply vessels. Clinical manifestations can be divided into three categories:

1) Typical manifestations: cerebral thrombosis can start suddenly, or it can slowly progress to aggravate, the main symptoms are weakness and numbness of one limb, crooked tongue, slurred speech or incomprehension of others' speech, etc., these symptoms are relatively common, and most people can recognize that cerebral thrombosis has occurred.

2) Atypical manifestations: There are also some patients who present with dizziness symptoms, which can be a spinning sensation, or only a sense of dizziness, with double vision, difficulty swallowing or choking on drinking water, or deviation to one side when walking, hitting the door frame, or hemibody pain, or limb shaking and other atypical manifestations, in fact, some special parts of the cerebral thrombosis, this type of thrombosis is atypical, but often the condition is more prone to change, and should also be noted.

3) Critical manifestations: If the area of cerebral thrombosis is large or cerebral thrombosis occurs in key parts, it will lead to confusion or even coma in the patient, and may also involve the respiratory and circulatory center and endanger the patient's life.

Therefore, cerebral thrombosis will have a variety of symptoms, if one or more of the above manifestations appear, it indicates that cerebral thrombosis may appear, and you should seek medical attention in time to seek professional diagnosis and**.
