What is Acute Cerebrovascular Disease? What are the causes and symptoms?

Vascular risk factorsThe most common cause of stroke is a small emboli on the lining of the blood vessels supplying the brain, which detach and lead to arterial-arterial embolism, known as ischemic stroke.

It may also be caused by cerebrovascular or thrombotic hemorrhage, which is a hemorrhagic stroke.

Patients with coronary heart disease and atrial fibrillation are prone to mural thrombosis, which can block cerebral blood vessels and lead to ischemic stroke.

Other factors include high blood pressure, diabetes, hyperlipidemia, etc.

Among them, hypertension is the most important risk factor for stroke in the Chinese population, especially in the early morning. The study found that early morning hypertension was the strongest independent factor for stroke events, and the risk of ischemic stroke in the early morning was 4 times higher than that in other periods, and the risk of stroke increased by 44% for every 10 mmHg increase in early morning blood pressure.

The main cause of stenosis and occlusion of the internal carotid or vertebral arteries is atherosclerosis.

In addition, arterial intimal hyperplasia and hypertrophy caused by collagen diseases, hypertension, arterial changes, rheumatic heart disease or arteritis, blood diseases, metabolic diseases, drug reactions, tumors, connective tissue diseases, carotid artery trauma, tumor compression of carotid arteries, carotid artery thrombosis associated with cervical lymphadenitis and tonsillitis in children, and congenital carotid artery distortion can cause internal carotid artery stenosis and occlusion, or stroke caused by blood vessel rupture and bleeding.

Primary Nurse 02 Internal Medicine Nursing 10 Neurological Diseases 01 Acute Cerebrovascular Diseases: ** and Pathogenesis, Clinical manifestations such as cerebral hemorrhage and cerebral thrombosis**.

Brain function declines due to a chronic lack of blood in the brain**. The main symptoms are headache, blurred vision, tinnitus, hearing loss, limb numbness, drowsiness, and sleep disturbances. As the disease progresses and the lesion worsens, patients may develop atherosclerotic dementia.

If the lesion compromises the bilateral cortical brainstem tracts, the lesion often presents with symptoms of pseudobulbar palsy. Brain function is widely affected, and specific clinical symptoms appear. The typical early symptoms of cerebral arteriosclerosis are slow progression, early nonspecific findings, and transient ischemic attack.

Symptoms of ischemic stroke in advanced cerebral arteriosclerosis include dizziness, visual field impairment, impaired language expression or comprehension, limb numbness and weakness, swallowing disorder, and limb movement incoordination. Upon careful examination, the patient may have neurological signs, such as bradyarity or pause in speech, bradykinesia, decreased range of motion, slightly higher muscle tone, hyperreflexia, positive metacarpal reflex, and Hoffman's sign. Patients with cerebral atherosclerotic dementia usually have vascular dementia.

Symptoms include memory loss, decreased ability to learn new knowledge and master new skills, emotional instability, personality disorders, etc.

In the later stages of the disease, the patient's mental health is completely reduced, and even severe dementia develops. Patients are unable to take care of themselves in daily life, lose their position in time and place, and often go out and get lost. Pseudobulbar palsy.

Cerebral arteriosclerosis ischemic lesions involve the cortical brainstem tract, and patients may develop pseudobulbar palsy. Symptoms include hemiplegia, dysarthria, dysphagia, and chewing. Breathing is also affected, the gait is slow and clumsy, and the stride is small and unstable.

The mandibular and oral reflexes are hyperactive, the nasolabial reflexes and sucking reflexes are positive, and the bilateral tendon reflexes are overactive. When the lesion involves the corticospinal tract, the patient's mood abnormalities are particularly pronounced, or uncontrollable crying and laughing may occur.

Patients with subcortical arteriosclerotic encephalopathy may present with multiple periventricular lacunar infarcts and subcortical white matter ischemic demyelination. It is more common in older patients after the age of 60. Symptoms include symptoms of pyramidal and extrapyramidal impairment such as progressive mental decline, cortical blindness, seizures, speech disturbances, ataxia, gait instability, parkinsonism, chorea, involuntary movements, and limb stiffness.

Early symptoms of cerebral arteriosclerotic psychosis are dizziness, headache, and recent memory loss, especially forgetting names and numbers. However, patients have good long-term memory and poor work efficiency, and are often unable to carry out their original work and study. As the disease progresses, the patient gradually develops sleep disturbances.

Some patients are emotionally unstable. As the disease progresses, patients may experience cerebral organic psychiatric symptoms, such as impaired consciousness, delusions, auditory hallucinations, etc.

Acute cerebrovascular disease refers to the acute lesion of the patient's cerebral blood vessels, which leads to the dysfunction of the patient's brain and forms a series of clinical syndromes.

The onset of acute cerebrovascular disease is sudden, and patients will quickly develop symptoms and signs of focal neurological deficits, such as slurred speech, limb numbness, limb paralysis, cognitive dysfunction, vision loss and other clinical symptoms.

There are many causes of acute cerebrovascular disease, and cerebral thrombosis caused by atherosclerosis is more common among middle-aged and elderly people. In addition, cardiogenic cerebral embolism is also an important cause of cerebrovascular disease.

In addition, cerebral hemorrhage and subarachnoid hemorrhage are hemorrhagic cerebrovascular diseases, and patients generally have severe headaches.

Sudden severe headache, crooked mouth and eyes, numbness in the limbs, dysfunction of the autonomic nervous system, vomiting, hiccups.

There is no strength in the body, and then there will often be some headaches, and there will be some numbness all over the body. And sometimes there will be some impairment in language function, and it will be fainting when unconscious. There will also be some crooked mouth and eyes from time to time.

In the early stage, there will be weakness of the limbs, and it will be accompanied by high blood pressure and high blood lipids, which can easily cause cardiovascular and cerebrovascular diseases, and it is easy to have dizziness and nausea.

There are many types of acute cerebrovascular disease, which are mainly divided into ischemic and hemorrhagic diseases. The first major causes of ischemic cerebrovascular disease include large artery sclerosis, which is mainly caused by hypertension, hyperlipidemia, diabetes and other factors; There are also some due to heart reasons, such as atrial fibrillation, where embolus falls off and blocks the cerebral blood vessels, resulting in cerebral infarction; There are other, rarely**, such as disorders of blood clotting mechanisms; There are also vascular abnormalities such as moyamoya disease, muscle fiber dysplasia; There are also some hereditary diseases. The most common for hemorrhagic cerebrovascular disease is hypertension.

1. Vascular risk factors: there are embolus in the inner wall of the blood supply vessels in the brain, which are easy to fall off and lead to arterial embolism, that is, cerebral ischemic embolism; 2. Bad lifestyle habits: such as smoking, unhealthy diet, lack of appropriate exercise, excessive drinking, etc., will increase the risk of acute cerebrovascular diseases; 3. Chronic disease ** element:

Patients with underlying diseases, such as coronary heart disease, hypertension, diabetes mellitus and hyperlipidemia, are prone to the occurrence of acute cerebrovascular diseases. 4. Other factors: such as mood swings, weather changes, overwork, gender, age, etc., are all predisposing factors for acute cerebrovascular diseases, which need to be avoided in time.

The main causes are trauma, crush injuries and contusions, which can cause acute cerebrovascular diseases. Because these traumatic injuries cause the rupture of blood vessels in a short period of time, causing cerebral hemorrhage, then cerebrovascular accidents will occur.

In my opinion, cerebral hemorrhage, cerebral arteriosclerosis, cerebral infarction, headache, fatigue, memory loss, comprehension impairment, these are all harms.

It is easy to form hemiplegia, it is easy to cause hemiplegia, it is easy to cause blood clots, cerebral edema will occur, and high blood pressure will occur.

The mortality rate is very high, it is easy to have a stroke, there will also be deviations, there may be no way to move normally, there may be drooling, and there will also be blood in the stool.

There is great harm, because this is likely to lead to a decline in physical fitness, which will lead to poor resistance and immunity, and then it will also affect normal life, aggravate the condition, and also induce some other diseases.

At present, the hazards of acute cerebrovascular diseases are relatively well recognized among the people, mainly in four aspects:

1. The mortality rate is relatively high, accounting for the second place among all causes of death.

In general, the overall mortality rate of acute cerebrovascular disease can reach 45%, and even if it survives, the mortality rate will increase exponentially within 3-10 years;

2. Statistics show that the disability rate of stroke patients in neurology is relatively high, up to 80%, generally in 40%-80%, which can be manifested as slurred speech, hemiplegia, joint contractures, cognitive impairment, emotional disorders, etc.;

3. The ** rate is relatively high, and the current statistical ** rate can reach about 47%, especially the ** rate in the first year after stroke is the highest, and the ** rate in 3-5 years is also multiplied, especially if the underlying diseases are not well controlled, the ** rate increases more obviously;

4. There are many complications, such as pneumonia, urinary tract infection or bedsores after long-term bed rest.

Yes, it is very serious, it can easily cause cerebral hemorrhage, and it will fall into a coma, and if you don't get timely medical treatment, you will die.

The symptoms of acute cerebrovascular disease must be very serious, once acute cerebrovascular disease appears, there will be sudden crooked mouth and eyes, severe headache, or sudden numbness of the face, tongue, lips and limbs, or general fatigue, sweating, low-grade fever, chest tightness, palpitations and other symptoms, you need to seek medical attention in time.

Yes, the disease is very serious, and if you have a cerebral hemorrhage, you are likely to die, and the probability of paralysis is very high.

It is very serious, and a slight accident may cause heart disease, sudden death, death, cardiovascular and cerebrovascular diseases.

a.Ischemic cerebral hematologic disease of Lee's duct.

b.Bloody cerebrovascular disease.

c.Cerebral embolism.

d.Transient ischemic episode.

e.Subarachnoid hemorrhage.

Correct Answer: a

My opinion is that people who suffer from this disease may be unconscious at any time, and if they do, they should try to put the patient on a flat ground. Allow the patient to breathe adequately. In addition, the bladder will also be affected, and hemiplegia will occur, and my opinion is that people with this disease must take good care of their body and can go to the doctor.

It may make people's consciousness very blurred, blood pressure will rise very quickly, and it will also affect people's bowel movements, the bladder will be affected, and it is easy to be paralyzed.

Patients with this condition will increase the chance of death, and there will also be hemiplegia, slurred speech, cognitive impairment, emotional disorders and other problems, my opinion is that the disease should be detected as early as possible, and it is necessary to follow the doctor's **plan and actively cooperate**.

This disease is very dangerous. It will affect the health of the brain, and there will be hemiplegia, sometimes spasms, sometimes emotional disorders, and there is no way to express one's thoughts well, which will lead to sudden death.

Acute cerebrovascular disease, this is a very large category, it is mainly divided into hemorrhagic diseases and ischemic diseases, to give a simplest example is what we often call cerebral hemorrhage or cerebral infarction, cerebral embolism, etc., these often occur in a short period of time, and may cause obvious clinical symptoms in a short period of time, and at this time go to the hospital for relevant examinations, it can be clear that it is because of cerebrovascular damage, which causes changes in various diseases.

For example, cerebral hemorrhage often reaches the peak of the disease in one or two hours, and causes headache, dizziness, nausea, vomiting, numbness and weakness of the limbs, speech dysfunction and other symptoms, so it is necessary to conduct a head CT examination in the emergency department to determine whether it is high blood pressure, cerebral hemorrhage or cerebral hemorrhage caused by aneurysm rupture, or even cavernous hemangioma, arteriovenous fistula, cavernous arteriovenous malformation, etc., which may be caused.

Therefore, it is necessary to carry out ** in a timely manner in this regard, which is the most common acute cerebrovascular disease we see, and the same is true for cerebral infarction, which will reach the peak of your condition in a short period of time, causing various clinical damage.

There are two main types of acute cerebrovascular diseases: first.

1. Ischemic cerebrovascular disease, including transient ischemic attack and cerebral infarction; Clause.

2. Hemorrhagic cerebrovascular disease, including cerebral hemorrhage and subarachnoid hemorrhage. Symptoms of acute cerebrovascular disease include: hemiplegia (weakness of hands and feet), hemisensory impairment (numbness of hands and feet), speech disorder (aphasia and slurred speech), choking on drinking water, difficulty swallowing, crooked corners of the mouth, salivation, decreased vision, hearing loss, dizziness, headache, drowsiness, lethargy, coma, etc.

Acute cerebrovascular disease is a disease that is prone to occur in middle-aged and elderly people, and generally speaking, acute cerebrovascular disease can be divided into two categories, one is hemorrhagic cerebrovascular disease, which includes old hemorrhage and subarachnoid hemorrhage. The other is ischemic cerebrovascular disease, which includes ischemic stroke and transient ischemic attack. The most common of these is ischemic stroke, which we also call cerebral infarction, cerebral thrombosis, and stroke.
