What causes brain atrophy and how is brain atrophy caused?

There are several causes of cerebellar atrophy:

First, it is hereditary. Such as spinocerebellar degeneration, ataxia, dentate nucleus, globus pallidus, Lewy body atrophy, etc.

2. Deformability, which is reflected in multisystem atrophy and cerebral atrophy.

3. Ischemia and hypoxia, more common in carbon monoxide poisoning.

Fourth, it is drug poisoning, such as phenytoin poisoning.

5. Inflammatory, causing the sequelae of inflammatory acute cerebellia, it can also cause cerebellar atrophy.

6. Alcoholism, alcoholic cerebellar degeneration is also one of the cerebellar atrophys.

7. Others, including neuroparaneoplastic syndrome, are the main causes of cerebellar atrophy.

Cerebellar atrophy is not a disease but a neuroimaging finding. Cerebellar atrophy can also be seen in some acute diseases, such as in the later stages of acute cerebellitis and in some people who are intoxicated by certain drugs or even in some clinically asymptomatic people. A common feature is a decrease in cerebellar volume and widening of the sulci on neuroimaging, which can be divided into localized and generalized cerebellar atrophy.

Brain cells are permanent cells that can never regenerate once they are broken, so all factors that cause damage to brain cells can cause brain atrophy. There are uncontrollable factors, such as age, with the increase of age, the brain capacity is gradually reduced, so it will cause physiological brain atrophy, or senile brain atrophy. There are also many controllable factors, such as chronic alcoholism that can lead to brain atrophy, local traumatic brain injury, or partial brain atrophy after a craniotomy.

After acute cerebrovascular disease, whether it is cerebral infarction or cerebral hemorrhage, it can also cause local cerebral atrophy. If there are risk factors such as chronic hypertension and diabetes that damage blood vessels, or if there is smoking that causes damage to small blood vessels, it will cause white matter degeneration around the ventricles, resulting in brain atrophy. At the same time, there are some degenerative changes, such as Alzheimer's disease, that is, senile dementia, or other types of dementia, which can lead to the occurrence of brain atrophy, so brain atrophy is a very, very many causes of the outcome.

1. Aging: With age, it is a normal physiological phenomenon for brain tissue to shrink to a certain extent.

2. Brain trauma: Traffic accidents, falls and other head injuries can cause damage to brain tissue, resulting in brain atrophy.

3. Neurological diseases

1) Alzheimer's disease and other forms of dementia patients gradually damage brain cells and lose the ability to communicate with each other, resulting in the loss of memory and thinking ability, which is the main cause of brain atrophy.

2) Huntington's disease is a genetic disorder that gradually damages neurons, usually starting in middle age, and over time, it affects a person's mental and physical abilities, leading to brain atrophy.

3) Vitiligo is a group of rare genetic diseases that damage the myelin sheath, which in turn leads to atrophy of brain tissue.

4) The immune system of people with multiple sclerosis attacks the protective coating around nerve cells, causing nerve cells to be damaged, leading to dementia and brain atrophy.

4. Infectious diseases:

1) AIDS attacks the body's immune system by disrupting the connections between neurons by releasing proteins and other substances. Toxoplasmosis associated with AIDS can also damage neurons in the brain.

2) Encephalitis is most commonly caused by the herpes simplex virus, which can harm neurons and cause symptoms such as confusion, seizures, and paralysis. Autoimmune diseases can also cause encephalitis.

Brain atrophy is common in older people and can be secondary to other disorders. Patients with cerebral atrophy have clinical manifestations of memory loss, forgetfulness, cognitive impairment, and behavioral difficulties. There is no very effective way to improve the circulation of brain tissue through drugs to resist the progression of brain atrophy as much as possible.

So what are the causes of brain atrophy? This issue is addressed in detail below.

1. Advanced age. Most older people have signs of brain atrophy when they have a brain exam. Earlier, it was believed that brain atrophy was a normal part of aging.

However, with further research, it has been found that the brain tissue of some elderly people has not atrophied and degenerated. Therefore, it can be proved that brain atrophy is not a normal manifestation of aging.

2. Intracranial infection.

When pathogenic microorganisms invade brain tissue with blood circulation, infection occurs locally in brain tissue. Infection can affect the normal function of brain tissue, cause local brain cell degeneration, necrosis, and cause local brain atrophy. Common intracranial infections include purulent meningitis, tuberculous meningitis, viral encephalitis, etc.

3. Traumatic brain injury.

Brain impacts, such as car accidents, can cause hematomas in the skull or directly damage brain tissue. Brain atrophy occurs when brain tissue is compressed or damaged, and then brain atrophy develops.

4. Intracranial tumors.

After the cranial nerve becomes cancerous, it forms cancerous tissue locally, and the cancer compresses the local brain tissue, resulting in atrophy and fibrosis of the brain tissue.

5. Neuropathy.

Certain neurological disorders cause degeneration and necrosis of nerve cells in the brain, resulting in local brain atrophy.

In summary, brain atrophy can occur at any age. Clinically, the main means of nourishing cranial nerves, improving cerebral circulation, and primary disease are used to carry out the disease. In particular, brain atrophy caused by infection with pathogenic microorganisms can occur without symptoms of cerebral atrophy if it is timely.

However, the cerebral atrophy of non-pathogen infection is difficult to recover due to the difficulty of recovering the functional form of cranial nerves, and the clinical effect is poor. Regardless of the cause of brain atrophy, once diagnosed, it should be actively accepted** to improve symptoms and improve quality of life as much as possible.

There are many causes of brain atrophy, some of which are physiological, such as age-related brain atrophy, also known as senile brain atrophy, which is often referred to as Alzheimer's disease. Some are pathological, such as neurodegenerative diseases, strokes, and so on.

In addition, it is common in traumatic brain injury, encephalitis, meningitis, cerebrovascular malformations, brain tumors, as well as long-term seizures, excessive smoking and alcohol, malnutrition (such as vitamin B12 deficiency), as well as thyroid lesions, carbon monoxide poisoning, alcohol poisoning, etc.

Cerebellar atrophy is due to the fact that the brain is not used very often due to age, and the source of the disease is blood circulation, which is not the capillaries in the brain

Cerebral atrophy refers to the phenomenon of organic lesions of brain cells due to various reasons, resulting in a decrease in the number of brain cells, a decrease in size, and a loss of weight. Brain atrophy can be caused by a variety of diseases. The main cause of cerebral atrophy is long-term chronic ischemia of cerebral blood vessels, which leads to a decrease in the deformability of red blood cells, insufficient effective blood perfusion of microvessels, and brain tissue.

There are many reasons for cerebral atrophy, with the increase of age, normal physiological phenomena will also cause cerebral atrophy, some diseases cause cerebral ischemia, hypoxia, high blood pressure, diabetes, hyperlipidemia, smoking and drinking and other bad habits.

1. Mainly degenerative diseases of the nervous system, which is the irreversible death of neurons caused by some unknown reasons, after the death of neurons, the cells of the cerebral cortex are reduced, which is naturally cerebral atrophy, and patients will have some cognitive dysfunction.

2. Cerebral ischemia, if there is chronic cerebral insufficiency, or cerebral thrombosis, a large number of brain cells will appear ischemia, hypoxia necrosis, and the brain will naturally atrophy.

3. It may be poisoning, such as carbon monoxide poisoning or other poisoning, which can also cause serious brain cell death and brain atrophy.

Hello, consider your case as cerebral atrophy. Hello, the ** principle of brain atrophy is:1

Early detection, early **, easy to achieve good efficacy2Promotes normal development, inhibits and improves abnormal movements and postures3Comprehensive treatment of large chong therapy:

In addition to the movement disorder, the combined language disorder, mental retardation, and behavioral epilepsy should also be carried out**4A combination of home training and physician guidance5Targeting, syndrome differentiation and disease differentiation, symptomatic treatment, regulation of the five internal organs, nutrition of brain cells, and promotion of brain tissue development.

Analysis: Cerebral atrophy is caused by multiple factors, such as heredity, traumatic brain injury, stroke, encephalitis, meningitis, cerebrovascular malformation, brain tumor, long-term seizures, excessive tobacco and alcohol, malnutrition, thyroid dysfunction, gas poisoning, alcoholism, cerebral arteriosclerosis, cerebral ischemia, hypoxia, etc., which can cause brain parenchymal destruction and atrophy, deformation and disappearance of nerve cells.

The main cause of cerebral atrophy is long-term chronic ischemia of cerebral blood vessels, which leads to a decrease in the deformation ability of red blood cells, insufficient effective blood perfusion of microvessels, and brain tissue is in a state of chronic ischemia and hypoxia, and the morphology and function of brain cells are affected, that is, brain atrophy is formed.

Cerebral infarction is the occurrence of ischemia and hypoxia or even necrosis in a certain area of the brain, which may be related to the lesions of blood vessels such as atherosclerosis and hypertension, or it may be due to thrombosis and embolus blocking a blood vessel in the brain, resulting in a lack of blood in this area. Cerebral infarction may progress slowly or acutely, but there will generally be aura symptoms before the onset of the disease, such as dizziness, headache, slurred speech, choking on water, numbness of one limb, and poor movement.

Brain atrophy is generally more common in the elderly, and there are many reasons for brain atrophy, so how is brain atrophy caused? This is a topic that many people are more concerned about. Next, we invite experts to introduce you to the relevant knowledge of brain atrophy, hoping to help you.

Cerebral atrophy varies greatly in severity and can produce symptoms and signs depending on the location and degree. Cerebral atrophy is mainly manifested as headache, dizziness, forgetfulness, insomnia, irritability, etc.; Some patients are unsteady on their feet, trembling in their hands and feet, and staggering in their walks; Some patients are paranoid, anxious, suspicious, and incoherent; With the development of the course of the disease, some patients have obvious memory loss or even loss, slow response, apathy, lazy speech, slow movement, and severe cases can lead to Alzheimer's disease. It should be noted that many patients with Alzheimer's disease have cerebral atrophy lesions, but Alzheimer's disease may not occur if there is cerebral atrophy, and the two cannot be simply equated, so there is no need to be overly anxious about cerebral atrophy, and it is necessary to follow the doctor's advice system**.

Brain atrophy is physiologically and pathologically distinct. Physiology is caused by the growth of age and the decline of body function, many elderly people have different degrees of physiological brain atrophy, this normal brain atrophy also affects the memory function of the elderly, but it is often mild, will not be progressively aggravated, does not affect the daily life of the elderly, this part of the people as long as they pay careful attention to the protection of brain cells, as appropriate to take brain health drugs. Pathology is a degenerative disease caused by a variety of reasons to reduce the volume of brain tissue, mostly caused by vascular diseases (such as cerebral arteriosclerosis, cerebral infarction, cerebral hemorrhage, hypertension, coronary heart disease, etc.), poisoning, infection, brain trauma, etc., causing brain parenchymal destruction and atrophy, deformation, and disappearance of nerve cells, among which the most common phenogen is caused by vascular diseases.

Some patients with pathological cerebral atrophy may have a severe degree of atrophy, or a special atrophy site, and some may develop cerebral dementia, which is difficult. Do you know anything about the above introduction? Now that we know the cause of brain atrophy, we should immediately take preventive measures to avoid the harm of brain atrophy.

Cerebral atrophy refers to the phenomenon of atrophy caused by organic lesions in the brain tissue itself due to various reasons. Pathologically, the volume of brain tissue is reduced, the number of cells is reduced, and the ventricles and subarachnoid space are enlarged. The disease mostly occurs in people over 50 years old, the course of the disease can be up to several years to decades, more men than women, can be divided into diffuse brain atrophy (including cortical atrophy, cerebellar atrophy and cortex, cerebellum, brainstem atrophy) and localized brain atrophy (more common after localized brain organic lesions such as trauma, vascular disease, intracranial localized ** infection, etc.).

Brain atrophy is a neuroimaging manifestation of many diseases, as it was originally named after the decrease in the size of brain tissue and the enlargement of the ventricles during CT or MRI examinations.

Cerebral atrophy is a decrease in brain size, brain parenchyma, and weight loss due to various causes. The main causes are traumatic brain injury, sequelae of poisoning, cerebral infarction, cerebral ischemia and hypoxia, cerebrovascular malformation, brain tumor, stroke 、..

There are congenital inheritances and acquired formations.

The disease is multicausal. By heredity

Traumatic brain injury, poisoning.

Sequelae, cerebral infarction,

Encephalitis, meningitis.

Cerebral ischemia, hypoxia,

Cerebrovascular malformations.

Brain tumors. Stroke, epilepsy.

Long-term seizures, excessive smoking and drinking

Malnutrition. Thyroid gland.

Functional lesions, cerebral arteriosclerosis.

Gas poisoning. Alcoholism.

It causes the destruction of brain parenchyma and the atrophy, deformation and disappearance of nerve cells, the most important of which is the most important gener.

Caused by long-term chronic ischemia of cerebrovascular vessels. Humanity from.

Embryonic development. From the beginning to the twilight of life, both the macro and micro aspects of the body are constantly metabolizing and metabolizing.

Energy metabolism. to obtain nutrients and remove the detriment of themselves.

Physiological function. so that they are more adaptable to the changing environment inside and outside the body. The key to accomplishing this function must be abundant in oxygen, i.e. in an effective manner.

Blood circulation. Below, there are enough.

Red blood cells carry oxygen and are impaired in their function and morphology. And when this damage does not cause serious changes in its physiological functions, it is the aging of a healthy person, if it occurs in a human being.

Brain tissue is healthy.

Elderly. Brain atrophy. Senior citizen.

Red blood cell deformability.

If it declines, the effective blood perfusion of the microvessels is insufficient, and the brain tissue is in chronic ischemia

Hypoxic state. Brain cell.

Morphology and function are inevitably affected, i.e., brain atrophy is formed.

At the same time, blood lipids.

The anomaly is being caused.

In elderly patients with cerebral atrophy, poor cerebral circulation perfusion plays an important role. There are also significant findings.

White matter atrophy.

Incidence of hypertension.

significantly higher than in patients with significant cortical atrophy, from which the analysis of atherosclerosis.

and hypertensive arteriole sclerosis play a role in the formation of senile cerebral atrophy, and the cerebral cortex is mainly enlarged in the brain.

Blood vessels are supplied by branches, and cortical areas are abundant.

Capillary network.

When the ability of red blood cells to deform decreases, red blood cells pass.

Capillary. Cortical atrophy occurs when the amount of oxygen is not delivered enough to meet the metabolic needs of cortical neurons.

The white matter of the brain is mainly composed of small and medium-sized.

Arterial blood supply, which is more likely to occur in people with high blood pressure.

Arteriole hyalineity, fibrinoid necrosis, and sclerosis lead to thickening of the arteriole wall, decreased elasticity, and vascular resistance.

Increase, blood flow.

Hypoperfusion, hyperlipidemia.

The formation of arteriosclerosis is more severe. Therefore, it is believed that high blood pressure,

Hyperlipidemia may be a cause of white matter atrophy. If the causes of cerebral cortical atrophy and white matter atrophy are the same, it is possible that there will be both white matter atrophy and cortical atrophy, and the number of patients with mixed cerebral atrophy will increase over time.

Lesions in this disease can be seen with flattening of the cerebral gyrus, widening of the sulci, and ventricula cisterna.

Enlargement, brain weight reduction. Often.

Cerebral cortex. Atrophy can be divided into different parts and scopes.

Localized and diffuse brain atrophy.
