What s going on with brain atrophy, what s going on with brain atrophy

Simple cerebellar atrophy can be caused by many reasons, although there are more, but its CT and MRI manifestations have their common characteristics, can be dominated by a certain part of atrophy, and its CT diagnosis should include two or more signs: (1) cerebellar sulci enlargement, more than 1mm; (2) Cerebellar pontine cistern enlargement, exceeding the distance between the superior edge of the cerebellum and the edge of the petrosal bone); (3) The fourth ventricle is enlarged by more than 4mm; (4) Enlargement of the superior cisterna of the cerebellum. The mere enlargement of the fourth ventricle and the presence of a large cisterna do not indicate the presence of cerebellar atrophy.

Cerebellar atrophy of various causes can also have certain characteristics, such as cerebellar atrophy caused by chronic alcoholism, which often involves cerebellar vermis, and is less common in the cerebellar hemisphere: olivine pontine cerebellar atrophy (degeneration) often involves the cerebellum, midcerebellar foot, ventral pontine brain, and olive nucleus atrophy, cerebellar nucleus, pontine tegmentum, and inferior cerebellar foot are usually unaffected. Symptoms often include cerebellar language such as ataxia, slurred speech, and poor fine motor skills.

When some patients have atrophy of olive and pontine, they may have symptoms of pyramidal tract damage such as dysphagia, which is a disease that seriously affects the quality of life of patients. At present, because the causes of this disease are diverse, some can not be determined, and the atrophy of olive-pontine brain may also be related to genetic factors, there is no effective measure for **, and the **neurology** is only neuronutrition and neuroprotection**. Recent experimental studies have found that stem cell transplantation has a good effect on this primary neurodegenerative disease, and related experimental studies have found that neural stem cell transplantation has a significant effect on cerebellar atrophy in animal models.

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, 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.

Therefore, cerebrovascular disease is the most common disease that causes cerebral atrophy, and gas poisoning, intracranial infection, and hereditary metabolic encephalopathy can cause cerebral atrophy.

Cerebral atrophy is the atrophy of brain tissue in the cerebral cortex due to long-term chronic ischemia. It is manifested by a significant decrease in memory of the near future. That is, many people say to do things, turn around and forget. In severe cases, dementia can occur.

It is the slow growth of the brain due to some influences, brain dysfunction, and lesions in the brain! Usually there is a loss of behavior, speech and memory!

Brain atrophy is actually a phenomenon that reduces the number of brain cells and shrinks the volume of brain tissue due to various reasons. This condition can be physiological or pathological. The physiological cause is that brain cells naturally undergo apoptosis with age, which leads to brain tissue atrophy.

Pathological causes may be related to illness or trauma. For example, cerebral infarction and cerebral hemorrhage, which are the most common in the elderly, will lead to local brain atrophy after recovery, and some neurological degenerative diseases may even cause global brain atrophy. Because the regeneration ability of brain tissue cells is very weak, the drugs that can promote the regeneration of brain cells that can be used at present do not have a particularly good function in promoting the growth of nerve cells in the human body.

Therefore, it is very difficult to recover after brain atrophy, and there is no good way to recover.

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 divided into radiographic manifestations and clinical manifestations. In terms of imaging manifestations, patients can find that the volume of the brain parenchyma is reduced, the cerebral cortex is reduced, and the volume of intracranial ventricles, sulci and other cavities is enlarged. Brain atrophy is a normal physiological change, but brain function can also decline, and fatigue, laziness, reduced reaction ability, and memory decline can occur in the early stage.

Severe brain atrophy can lead to loss of self-care ability, vegetative status, and even death. Patients with the above-mentioned cognitive impairment or even dementia need to undergo routine brain exercises or go to a regular hospital to avoid progressive aggravation of the condition.

Brain atrophy is a decrease in the size of brain cells due to various reasons, and the decrease in the number of brain cells eventually produces the atrophy of brain tissue. It can be caused by both pathological and physiological causes. Physiological atrophy is common when brain tissue degenerates and the volume of brain tissue decreases with age.

Pathological atrophy is often secondary to large-scale cerebral infarction, softening foci of cerebral hemorrhage, etc. Patients with cerebral atrophy can lead to cognitive and behavioral decline, memory loss, mental decline, and personality changes.

Brain 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 disease that causes cranial nerve dysfunction due to the corresponding reduction of brain tissue cells, and the main clinical symptom of cerebral atrophy is dementia, especially the elderly are prone to Alzheimer's disease.

What is the situation of brain atrophy at the age of 50 Early detection and early detection of brain atrophy, actively take correct measures to control some risk factors in the bud, prevention still has a certain effect, at least can delay the occurrence and development of the disease. Actively prevent and treat vascular diseases, such as hypertension, diabetes, hyperlipidemia, arteriosclerosis, etc., increase social activities, use in and out, often read books and newspapers, write and calculate, run the brain regularly, eat lightly, and have smooth stools.

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

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.

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.
