What diseases can be caused by insufficient blood supply to the brain?

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.

What are the main causes of insufficient blood supply to the brain?

Some arterial vascular lumen narrowing or vasospasm, blood flow through the blood flow is reduced, cerebral insufficiency is not included in the general internal medicine department of the hospital, resulting in insufficient blood supply to the brain area;

Hemodynamic disorders, in which the blood supply to the brain tissue is inadequate when blood pressure decreases and stroke volume decreases;

Increases in blood viscosity, slowness and changes in blood composition can also occur due to certain causes, and insufficient blood supply;

Microthrombosis, microthrombosis, that is, the atherosclerotic plate of the artery is shed, forming microemboli in the bloodstream, which blocks the blood vessels with the blood flow to the arterioles, and the local blood supply to the brain is insufficient.

Causes of cerebral blood deficiency.

Cardiovascular and cerebrovascular factors.

The blood to the brain is pumped by the heart, and if you have various heart diseases, heart failure, heart dysfunction, weak or insufficient pumping, you will have insufficient blood supply to the brain.

Regardless of the cause, the narrowing of the diameter of the arteries supplying blood to the brain, or the stiffening and reduced elasticity of the tube wall, will affect the normal blood supply to the brain, resulting in insufficient blood supply to the brain. The main among these causes is atherosclerosis (high blood pressure, coronary heart disease, diabetes, dyslipidemia, high cholesterol, obesity, smoking, alcohol consumption and other risk factors for atherosclerosis), as well as arterial stenosis and arteritis.

Cerebral insufficiency is caused by long-term cerebral arteriosclerosis, decreased elasticity of cerebral blood vessels, and plaque formation on the walls of cerebral blood vessels, which further leads to lumen narrowing. The narrowing of the lumen of the blood circulation results in a decrease in blood flow to the brain tissue. The clinical manifestations of cerebral ischemia are dizziness, lightheadedness, and head discomfort.

Other patients have heart disease, such as heart failure and a reduced ejection fraction in the heart, resulting in an inadequate blood supply to the brain.

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.

Cerebral insufficiency refers to the deficiency of blood in a certain part of the human brain, which causes the disorder of brain function. Cerebral insufficiency** is associated with cerebral arteriosclerosis.

Cerebral insufficiency, cervical basal insufficiency, Meniere's syndrome, otolithiasis, etc. will cause vertigo, and they are ultimately caused by poor microcirculation.

The clinical manifestations of cerebral insufficiency are as follows:

Motor nerve dysfunction.

This type of aura is the most common. Due to insufficient cerebral blood supply, the nerves in charge of human motor function fail, and common manifestations such as sudden crooked mouth, drooling, difficulty speaking, slurred speech, aphasia or speechlessness, difficulty swallowing, weakness or inactivity of one limb, falling of objects, unsteady walking or sudden falling, and some limbs spasm or throbbing.

Sensory dysfunction.

Due to insufficient blood supply to the brain, the analysis area, sensory organs and sensory nerve fibers are affected, often manifested as facial numbness, tongue numbness, lip numbness, and numbness or foreign body sensation in one limb; Some have blurred vision, and even sudden temporary blindness; Many people have a sudden feeling of dizziness; spontaneous pain in some limbs; Others suddenly have tinnitus, hearing loss, etc.

Hello, according to the analysis of your condition, there are many reasons for insufficient blood supply to the heart and brain, including arteriosclerosis of the arteries, hypertension, hyperlipidemia, coronary heart history, long-term fatigue, lack of sleep and other reasons. After this situation occurs, first combined with the patient's own discomfort, there are obvious discomfort symptoms to take some drugs to dilate blood vessels, promote blood circulation and eliminate blood stasis, pay attention to self-regulation, ensure adequate sleep, avoid fatigue, low-salt, low-fat and light diet, have a positive ** of the original disease, appropriate exercise, maintain a good attitude, insufficient blood supply to the heart and brain can be well improved, and the condition changes in time.

Lack of oxygen to the brain, dizziness, dizziness, severe may be coma in the morning.

Cerebral insufficiency refers to the disorder of brain function caused by insufficient blood in a certain part of the human brain. Cerebral insufficiency** is associated with cerebral arteriosclerosis. The main ** are:

1) The lumen of some arteries is narrowed or vasospasm, and the blood flow through is reduced, resulting in insufficient blood supply to the brain area; (2) hemodynamic disorders, when blood pressure decreases and stroke volume decreases, the blood supply to brain tissue is insufficient; (3) The increase in blood viscosity, the slowness of blood and the change of blood composition caused by some reasons can also occur and the blood supply is insufficient; (4) Microthrombosis, microthrombosis, that is, the atherosclerotic plate of the artery falls off, forming microemboli in the bloodstream, and blocking the blood vessels with the blood flow to the arterioles, then there will be insufficient local blood supply to the brain. Eat more vegetables, eat less greasy food, sleep is the most important thing, preferably about 10 hours a day.

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

This situation like yours is most likely to cause neurasthenia, strengthen nutrition, pay attention to rest.

Your doctor friend is a fool, and anemia will say yes.

Inadequate blood supply to the brain.

He simply didn't understand the meaning of anemia and cerebral insufficiency.

I don't mind eating but not much, and I feel that your body is caused by eating those things that are not nutritious for a long time! And also.

The most important thing is to arrange your work and rest time reasonably, otherwise it will be useless for you to eat more nutritious things!

Early** is king!
