What are the complications of insufficient blood supply to the brain?

If the human body has a long-term shortage of brain supply, the most harmful is our brain, if the brain does not have the support of these nutrients, there is no oxygen, and it needs to be maintained by old classmates, which will affect the state of the patient's whole person, whether it is spirit, sleep, exercise, or intelligence.

Long-term insufficient blood supply, the patient's mental state will undergo great changes, such as drowsiness, sleepiness, memory will gradually be lost, and even the sensitivity of smell and hearing will all decline, and some patients will also have slow reaction, fatigue and other phenomena, which will greatly affect life.

At the same time, patients with insufficient cerebral blood supply will feel very sleepy, no matter how long they sleep, they will feel that they will not be relieved of their energy, of course, there are some special patients, there may be some overexcitement or mania and other manifestations, which is different from person to person, after all, everyone's physical condition is different.

At the same time, the ability to react will gradually decrease, such as it becomes difficult to lift the legs, the pace becomes slow, and then when passing through some relatively uneven or rough ground, it is very easy to fall symptoms, which greatly increases the potential safety hazards.

Insufficient cerebral blood supply is caused by many aspects, it may be because of the bad living habits of some people caused by cervical spondylosis, and the bad posture of office workers will lead to insufficient blood supply to the cervical spine, so we must pay attention to rest, avoid bowing your head, avoid keeping the same action for too long, and move appropriately.

Insufficient cerebral blood supply, in fact, means that there is a disorder of blood circulation in the brain, resulting in some ischemia or hypoxia, this symptom is not to be taken lightly, if it is not in time, it may lead to cerebral infarction, and some patients will also have more serious dementia or death and other phenomena, so we must seek medical attention as soon as possible when we have symptoms such as dizziness, headache, dizziness, etc.

Cerebral insufficiency usually has several consequences:

First, chronic cerebral insufficiency can lead to symptoms such as headache, dizziness, memory loss, poor concentration, sleep disturbance, nausea, vomiting, and in severe cases, syncope, visual impairment.

Second, if it is an acute cerebral insufficiency, it is usually caused by acute cerebral infarction, and patients are often accompanied by unilateral facial numbness, numbness of hands and feet, limb weakness, stiffness, etc.

Third, chronic cerebral insufficiency is often closely related to the development of dementia, and if the blood flow to the brain is decreasing, dementia can also be induced.

It is recommended that patients with chronic cerebral insufficiency actively choose drugs that inhibit platelet aggregation and anticoagulation under the guidance of doctors, such as aspirin, clopidogrel, etc.

What are the complications of cerebral insufficiency, cerebral blood supply.

Complications of insufficiency are dizziness, which manifests mainly as the head.

Feeling of drowsiness, drowsiness, lack of concentration.

Medium, fatigue, slurred speech, blurred vision, remembering.

Decreased memory, cognitive decline, dementia, depression.

Depression and anxiety disorders, if they continue to develop in the brain.

The most serious complication of insufficient blood supply is cerebral infarction.

1. If the cerebral blood supply is insufficient, coma symptoms will occur.

The average cerebral blood flow of normal adults is 40-60 ml of brain tissue per 100 grams of empty clock, and the brain is very sensitive to insufficient blood**, when the blood shed fluid ** drops to 75%-85% of the normal value, people will have judgment errors and consciousness disorders, and coma can occur when it drops to 51%-65% of the normal value.

2. Cerebral blood supply is insufficient, and symptoms of nerve damage may occur.

When there is a severe cerebral insufficiency, there will even be a phenomenon of cerebral circulation arrest, which will lead to the loss of awareness and blindness for a few seconds, and irreversible neuronal damage can be caused in a few minutes, and there may be disorders in limbs, touch, vision, hearing, memory, etc.

Patients may have symptoms such as headache, dizziness, tinnitus, numbness of limbs, insomnia, dreaminess, blurred vision, and significant memory loss.

3. Middle-aged and elderly people suddenly have numbness or weakness on one side of the limb, cannot hold objects, the corners of the mouth are crooked, the speech is not clear, and the vision is hazy or fluttering in one eye. Such symptoms are caused by insufficient blood supply to the brain, which can be reversed, which is medically called "transient cerebral ischemia", which is a signal of impending stroke.

4. A large number of studies have been conducted by domestic and foreign scholars to find that before the onset of Alzheimer's disease and cerebral infarction, patients have a history of long-term chronic cerebral insufficiency, and if chronic cerebral insufficiency is not treated in time, it may cause cerebral atrophy, Alzheimer's disease and cerebral infarction.

First of all, chronic cerebral insufficiency can lead to cerebral ischemia and hypoxia, resulting in extensive diffuse lesions in the brain parenchyma, and the integration function of the brain will be significantly impaired. Patients may have symptoms such as headache, dizziness, tinnitus, numbness of limbs, insomnia, dreaminess, and significant memory loss. Some of them will also manifest as a sudden change in personality, which is very different from usual.

All these indicate that the elderly have symptoms of brain function decline caused by chronic cerebral insufficiency. In addition, there is another situation that should arouse people's high vigilance: middle-aged and elderly people suddenly have numbness or weakness on one side of the limb, cannot hold objects, the corners of the mouth are crooked, the speech is not clear, and one eye is black or the vision is fluttering.

Such symptoms can be reversed, which is medically known as "transient cerebral ischemia" and is a sign of an impending stroke.

Secondly, the mechanism of cerebral blood supply is very complex, and from an anatomical point of view, the two major arteries that nourish brain tissue are the carotid artery and the vertebrobasilar artery. The carotid artery system is the main channel of blood flow in the brain, the blood of the brain 3 4 comes from the carotid artery, and the vertebrobasilar artery mainly nourishes the inner ear, pons, midbrain, diencephalon, cerebellum, occipital cortex and temporal lobe. Smallening of the caliber of the intracranial and extracranial arteries or stiffening of the blood vessels from any cause can reduce the blood supply to the brain.

Among the many causes of narrowing of cerebral blood vessels, the most important is atherosclerosis, and a significant proportion is caused by narrowing of extracranial blood vessels. In addition to vascular factors, the speed of blood flow also plays a big role. Studies have shown that there is a direct relationship between cerebral blood flow and blood pressure, and that blood pressure that is too high or too low will reduce cerebral blood flow.

With systolic blood pressure as the standard, as the blood pressure increases, the cerebral blood flow increases, but when the blood pressure exceeds 160 mm Hg, the cerebral blood supply decreases. Changes in blood composition also have a certain impact on the cerebral blood supply, and if the concentration of cholesterol in the blood is too high, it will be deposited in the arterial blood vessel wall, narrowing the lumen of the blood vessels, resulting in insufficient blood supply to the brain, and even causing cerebral infarction.

1. It is the dislocation of the cervical vertebrae, the narrowing of the blood vessels, and the insufficient blood supply is reduced through the blood volume.

2. Hemodynamic disorder, when blood pressure is lowered, the heart shock force is reduced, and the blood supply is insufficient 3. The blood viscosity is high, the blood flow is slow, and the blood supply may be insufficient.

4. Microthrombosis, falling off from the arteries, forming embolus in the blood to block blood vessels, will cause brain diseases, cerebral infarction, cerebral hemorrhage, etc., must be **.

The most common symptom of cerebral insufficiency is dizziness or even syncope... It is mainly caused by arteriosclerosis and narrowing of blood vessels, and it is easy to develop into cerebral infarction if it is not treated for a long time.

Cerebral insufficiency generally refers to insufficient blood supply to the cerebral arteries, and the main symptoms are dizziness, headache, and even syncope, and long-term cerebral insufficiency can cause cerebral atrophy.

What are the symptoms of insufficient blood supply to the brain?

Generally, it is dizziness, and some will faint.
