What are the symptoms of lacunar cerebral infarction in the brainstem

Brainstem lacunar cerebral infarction refers to the occurrence of cerebral infarction in the brainstem, which is common in the pons. Then, the onset of brainstem cerebral infarction is more acute, and most of them occur when they are resting quietly, and the main manifestations are hemiplegia or quadriplegia, dysphagia, dysphonia, hyperthermia and impaired consciousness, and other symptoms. At the same time, due to the different blood vessels involved, the location of the infarction is different, and it is manifested as cross paralysis.

Patients with cerebral infarction in the brainstem also have symptoms of cerebral infarction, such as crooked mouth and eyes, salivation, hemiplegia and other symptoms.

In order to reduce the incidence of brainstem cerebral infarction, we should learn more about cerebral infarction in daily life and do a good job in preventive health care. Introduce readers to read about cerebral infarction.

Clinical manifestations of lacunar cerebral infarction, manifestations of cerebellar infarction, the best method of cerebral infarction.

Clinical presentation.

Pure sensory type: sensory disturbances on one side, lips, mouth, or limbs, such as cold, heat, tingling, swelling, hypertactile and other mild sensory disorders.

Pure motor cleoplegia and its variants: weakness of one side, upper and lower extremities (hemiparesis).

Ataxia hemiparesis: weakness of one lower limb, unsteadiness in walking, and may be accompanied by sensory impairment;

Dysarthria-clumsy hand syndrome: central facial weakness, dysarthria, eating intake, mild dysphagia, hand weakness, clumsiness in writing and other ataxia manifestations;

Sensorimotor stroke: sensory deficits and hemiparesis in one limb, with sensory symptoms preceding motor symptoms; 6.Fundus examination may show signs of retinal arteriosclerosis.

The disease mostly occurs in middle-aged and elderly people aged 40-60 years and above, more males than females, often accompanied by hypertension, lacunar cerebral infarction has a sudden onset, mostly acute onset, some are gradual or subacute onset, 20% of the symptoms of transient cerebral insufficiency onset, mostly in daytime activities.

The clinical manifestations are diverse, and there can be more than 20 clinical syndromes, which are characterized by mild symptoms and single signs.

1. The prognosis is good, without headache, increased intracranial pressure and impaired consciousness. Clinic.

Lacunar cerebral infarction.

It is a common type of cerebral infarction, accounting for about 20% of cerebral infarctions. This type of infarction is small in size, like a small cavity. It mainly refers to ischemic microinfarcts that occur in the deep white matter of the cerebral hemispheres and brainstem.

Penetrating arteries that affect the deep part of the brain cause ischemia, necrosis, and liquefaction of brain tissue, resulting in the formation of a cavity. Lacunar cerebral infarction is often caused by hypertension, arteriolar sclerosis, and degeneration of lipids in the walls of the small arteries, but other causes such as hemodynamic abnormalities, blood abnormalities, and various types of emboli can also cause lacunar cerebral infarction. Lacunar cerebral infarction can be divided into sensory impairment, pure sports shoe hemiparesis, sensory sports shoes, ataxia hemiplegia, and clumsy hand-hand syndrome according to different clinical symptoms.

Grade 3 hypertension.

According to the classification of hypertension, it is classified as severe hypertension, and the risk level is critical.

Lacunar cerebral infarction is actually a mild cerebral infarction, the condition is not very serious, and the symptoms are not particularly obvious. However, the incidence of lacunar cerebral infarction is relatively high, and it is easy to reverse, so it needs to be carried out in a timely manner, and its symptoms should be understood before **. So what are the symptoms of lacunar cerebral infarction?

1. Often choke when drinking water.

Frequent drinking of water and choking cough is one of the symptoms of lacunar cerebral infarction. It is very common to choke on water at ordinary times, but if you often choke when drinking water, and every time you cough constantly, it is very likely that you are suffering from lacunar cerebral infarction and need to seek medical examination and ** as soon as possible.

2. Dizziness and headache.

If you suffer from lacunar cerebral infarction, you may also experience dizziness and headache, which is mainly manifested as sudden dizziness or headache, which is not very obvious and is often thought to be caused by overexertion. If similar symptoms occur frequently, it may be caused by lacunar cerebral infarction.

3. Mild language impairment.

The symptoms of lacunar cerebral infarction also include mild speech impairment, the speed of speech becomes relatively slow when the patient speaks, and sometimes the intonation and voice will also change, and the tongue always feels stiff and wooden, which is particularly uncomfortable.

4. Memory loss.

Memory loss is also a common symptom of lacunar cerebral infarction. Once suffering from lacunar cerebral infarction, the function of the brain will be affected to a certain extent, although it will not become mentally retarded, but it will make memory loss, patients may forget some things they have done before, a small number of patients will have dementia symptoms, but this situation is relatively rare, in most cases there will be no consciousness disorder, mental symptoms are also extremely rare.

5. Hemiparesis or sensory impairment.

Lacunar cerebral infarction is relatively not very serious, but it may also affect the motor center of the brain, resulting in sensory impairment or hemiparesis, sometimes accompanied by mild central facial paralysis, and generally no symptoms of ataxia.

Luminal infarction is usually atypical. Most of them won't be very powerful. Some have only a single symptom. Most have dizziness, headaches, or numbness in the limbs. It can only be detected on CT scan.

After hearing about lacunar cerebral infarction, some people will ask what the symptoms of the disease are, although it is also one of the common cerebral infarction diseases, but it still has its own characteristics and differences, so it is indeed necessary for us to understand, according to experts, the symptoms of lacunar cerebral infarction should also be divided into several situations to analyze, as follows: 1. The symptoms of pure sensory lacunar cerebral infarction are numbness in one side, arm and leg, and no symptoms such as limb weakness, hemianopia and aphasia. Hand-mouth syndrome occurs when the numbness of a patient with lacunar cerebral infarction affects only one side of the face centered around the mouth and distal to the ipsilateral arm, particularly the hand.

Paresthesias such as cold, heat, pain, or stiffness may be present in the affected area. These are all symptomatic manifestations of lacunar cerebral infarction. 2. Simple dysarthria-type lacunar cerebral infarction, all have mild language impairment, the symptoms of lacunar cerebral infarction can be manifested as slurred speech, inaccurate pronunciation of words and intonation, but no phonemic error, completely understandable, some patients with lacunar cerebral infarction have poor sense of voice, speech slows down.

However, the symptoms of lacunar cerebral infarction are not facial, hemiplegia, pyramidal tract signs, and there is no pharyngeal, palatinal and throat paralysis. The lesion site of lacunar cerebral infarction is mainly located in the basal ganglia area, and has a feedback connection with the cortical language center, which is prone to compensation and plays an auxiliary role in its articulation movement. 3. The symptoms of hemichora lacunar cerebral infarction are mainly seen in middle-aged and elderly patients with more severe hypertension arteriosclerosis or atherosclerosis, and the main reason is lacunar infarction caused by the occlusion of sclerotic tiny arteries.

Lacunar cerebral infarction patients are most common in the left upper and lower limbs, with the upper limbs alone or the upper limbs of the face, followed by the right upper and lower limbs or the right upper limbs. The above is described from the three situations, the types of diseases are diverse, the symptoms are also different, how to more accurately judge the early symptoms of the disease is very necessary, I hope these medical knowledge can help you more, you can also consult more professional understanding, master more knowledge of the symptoms of cerebral infarction.

Lacunar cerebral infarction is a mild form of cerebral infarction, which is more common in the elderly. The cerebral blood vessels that cause infarction are not the large and middle blood vessels in the brain, but the small arteries in the deep part of the brain are occluded, resulting in ischemic malacia lesions of brain tissue; Necrotic brain tissue is engulfed by macrophages, removing the small cavities left behind are called cavities. These cavities are small and can range from 2 to 4 mm, most commonly; The number can range from multiple to even dozens.

Although small spaces can be formed, most of them have no obvious symptoms, let alone aphasia and hemiplegia. Even if the symptoms are mild, such as memory loss, concentration or transient ischemia, few people think they have a cerebral infarction. In particular, middle-aged patients (around 40-50 years old) sometimes go to the hospital for attention and memory loss, but think that it is just fatigue syndrome and neurasthenia.

Most of them don't take it seriously, they don't care, they do what they have to do. There are a small number of patients who have facial paralysis and aphasia, resulting in mental decline and even dementia, so they pay attention to seeing a doctor. Since lacunar cerebral infarction is caused by the occlusion of tiny arteries deep in the brain, and the symptoms are usually not obvious, why do aphasia and dementia also occur?

This is because the patient is not diagnosed and treated in time after the occurrence of lacunar cerebral infarction, and the lacunar cerebral infarction occurs repeatedly and repeatedly, accumulating more and more lacunar spaces, which gradually aggravates the condition and thus has serious consequences.

Lacunar cerebral infarction, including lacunar cerebral embolism and lacunar cerebral thrombosis, the most common cause of lacunar cerebral embolism is due to emboli blocking cerebral blood vessels, occluding the tiny arteries in the deep part of the brain, resulting in interruption of blood flow, causing ischemic malacia lesions of brain tissue, and corresponding neurological symptoms, which can occur at any age. Lacunar cerebral infarction is a serious disease that endangers human life. The disability, mortality, ** and morbidity of this disease are extremely high.

So? What causes lacunar cerebral infarction?

There are many lacunar cerebral infarctions, mainly due to cerebral vascular blockage and cerebral blood circulation disorders, that is, the result of the joint action of cerebral blood vessels and blood.

1. Blood component lesions:

Increased blood viscosity. Such as hyperlipidemia, hyperglycemia, hyperproteinemia, dehydration, polycythemia, leukemia, thrombocythemia, etc.

Abnormal coagulation mechanisms. Such as thrombocytopenic purpura, hemophilia, use of anticoagulants, vagal intravascular coagulation, etc. In addition, pregnancy, postpartum, post-surgery, and taking contraceptive food can cause coagulation.

2. Changes in blood motility: such as hypertension (about 5575 of non-embolic cerebrovascular diseases), hypotension, cardiac dysfunction (heart failure, coronary heart disease, atrial fibrillation, conduction block), etc.

3. Vascular wall lesions: atherosclerosis (about 70% of patients with cerebrovascular disease), arteritis (rheumatism, tuberculosis, etc.), congenital anomalies (aneurysm, vascular malformations, etc.), trauma, poisoning, tumors, etc. 4. Miscellaneous.

The influence of extravascular factors is mainly the compression of lesions adjacent to large blood vessels (such as cervical spondylosis, tumors, etc.), which affects blood supply insufficiency.

Various emboli formed outside the skull, etc.
