Focal changes in the substance of the brain of a dystrophic nature. Focal change in the substance of the brain of a dystrophic nature

When conducting CT (MR) studies in the substance of the brain, it is possible to detect foci of a dystrophic nature (like gliosis), atrophic nature (like a cerebrospinal fluid cyst), as well as calcifications. In chronic tissue ischemia, some other characteristic changes can also be detected, for example, periventricular leukoaraiosis (a change in the structure and density of the substance around the ventricles), often with the presence of small cysts in the basal ganglia, as well as in the outer and inner capsule of the brain. Quite often also signs (replacement character) come to light.

Causes and Predisposing Factors of Changes in the Brain

Focal changes include pathological processes that occur in a specific area of ​​the brain. In the brain tissues, modifications of a different nature occur (scars, cysts, necrosis). The most often focal changes of a dystrophic nature are found:

1. In the elderly. So, the probability of finding dystrophic foci increases significantly with age. Pathological changes in intra- and extracranial vessels, narrowing of the vascular lumen and brain ischemia provoked by these factors play a role here.
2. In persons with diabetes mellitus. With this pathology, angiopathy often occurs, manifested by changes in the vascular wall, impaired vascular permeability, and impaired vascular patency. Against this background, strokes often also occur.
3. In people with other angiopathy, anomalies in the development of the vascular bed of the brain (for example, an open circle of Willis), thrombosis (violations of the lumen of another etiology) of extra- and intracranial arteries.
4. In persons with exacerbation of cervical osteochondrosis. With a disease, the brain ceases to receive oxygen in sufficient quantities. As a result of oxygen starvation, areas of ischemia appear.
5. Those who have suffered a trauma of the skull, brain. Restructuring of the brain substance in the focus of contusion after injury can lead to the appearance of a focus of gliosis, cysts or calcification.
6. In persons exposed to long-term intoxication (exo- or endogenous). So, the first group includes people who abuse alcohol, take toxic substances (or are exposed to them in production, for example, workers in paint production shops). To the second - people with long-term current diseases (infectious, inflammatory).
7. In patients with oncological processes of the brain during examination, dystrophic foci are found.

Methods for detecting dystrophic foci in the brain

The main methods for detecting dystrophic (and other) parenchymal lesions in the brain are CT and MRI. In this case, the following changes can be identified:

1. Foci of the type of gliosis.
2. Cystic areas due to atrophy (and trauma).
3. Calcifications (as an example, due to hematoma impregnation with calcium salts).
4. Periventricular leukoaraiosis. Although not directly related to focal changes, it is a significant marker of chronic ischemia.

On the CT scan at the level of the third ventricle and the posterior horns of the lateral ventricles, blue arrows indicate areas of a cystic nature (the result of necrosis of the brain substance in the past): a small one in the area of ​​the right thalamus and a larger one in the occipital lobe on the right. There is also a change in the density of the substance of the brain around the posterior horn of the right lateral ventricle. The Sylviian fissures are enlarged, which indicates hydrocephalus (atrophic, replacement).

On the CT scan at the level of the bodies of the lateral ventricles, blue arrows indicate cystic (atrophic) areas in the parietal and occipital lobes on the right (consequences of a stroke). There are also signs of chronic cerebral ischemia, more pronounced on the right (periventricular leukoaraiosis).

CT scan of the head at the level of the 4th ventricle, cerebellar peduncles: in the left hemisphere of the cerebellum (at the base, near the left cerebellar peduncle) there is an atrophic area (consequences of a stroke). Pay attention to how the external cerebrospinal fluid spaces of the brain are expanded.

Blue arrows on the CT scan indicate areas of periventricular leukoaraiosis (around the anterior and posterior horns of both lateral ventricles). The red arrow also indicates "fresh" (on the right in the occipital lobe).

The presence of dystrophic focal changes in the brain in many cases is a consequence of chronic ischemia and is often combined with atrophic (replacement) hydrocephalus, especially in people who take alcohol long time who are exposed to intoxications of a different nature, who have had a stroke earlier or a head injury.

On the scan (CT) of the head - signs replacement hydrocephalus(due to necrosis of the brain parenchyma), with the presence of multiple foci atrophic character on the left side - in the occipital lobe (1), in the parietal lobe (2) and on the right side - in the head of the lenticular nucleus, periventricular to the body of the ventricle (3). The diameter of the lateral ventricles is expanded (marked with an arrow). Around the horns of the lateral ventricles there is a hypodense (low density on CT) zone.

Results

Dystrophic focal changes can be detected by CT and MRI in the brain of any person. Their detection may indicate a past pathology (traumatic, ischemic). If the foci are small in size and localized in the peripheral parts of the brain or in the white matter, basal ganglia, the prognosis for the patient's future life is favorable. But focal changes in the stem localization, on the legs of the brain, the thalamus are more unfavorable and may be the cause of the appearance of neurological symptoms.

All types of circulatory disorders in the human body also affect the substance of the brain, which ultimately affects its integrity and the possibilities of normal functioning.

And the “starvation” of cells, which is provoked by a violation or complete cessation of blood supply (in medicine, this process is called ischemia), causes a change in the substance of the brain of a dystrophic nature. That is, degeneration, and sometimes, although very rarely, even the disappearance of tissues and a significant deterioration in their function.

We will talk more about this pathological condition in the article.

Types of change

In medicine, dystrophic manifestations in the substance of the brain are divided into two types:

1. Diffuse.
2. Focal.

In the first case, pathological changes evenly spread to the entire brain, and not to its individual sections. They are caused both by general disturbances in the functioning of the circulatory system, and or by infections (meningitis, encephalitis, etc.).

Diffuse changes are manifested mainly by a decrease in a person’s working capacity, a dull headache, difficulties in switching to another type of activity, a narrowing of the patient’s circle of interests, apathy and sleep disorders.

And what is a focal change in the substance of the brain of a dystrophic nature, can be understood already by the fact that various minor pathologies can cause it:

• cysts (small cavities that form in the brain)
• medium-sized foci of necrosis (tissue death in some areas, caused by a lack of nutrient intake);
• gliomesodermal (intracerebral) scars that occur after injuries and concussions;
• minor changes in the structure of the medulla.

That is, these are pathologies that cause circulatory disorders in a small area. True, they can be both single and multiple.

Causes of dystrophy

The full picture of the appearance of dystrophic changes is not yet clear to researchers. But numerous observations led to the conclusion that most cases of this pathology have a genetic predisposition. The action of provoking factors only accelerates the development of the process or enhances its manifestation.

Therefore, the causes that cause focal changes in the substance of the brain of a dystrophic nature can be safely divided into genetic anomalies and acquired ones. Although it should be noted that acquired causes are still a very conditional definition in this case, since they begin their destructive effect only if the patient has a tendency to this pathology.

Focal change in the substance of the brain of a dystrophic nature: symptoms of the development of the disease

Symptoms of a change in the substance of the brain of a dystrophic nature are most often manifested quite clearly, but, unfortunately, this happens when the disease is already strongly progressing. Therefore, it is important to pay attention to the appearance of even small deviations in the state of health.

Is there an age limit for the disease?

It should be noted that single focal changes in the substance of the brain of a dystrophic nature occur not only in the elderly, but also in persons under the age of fifty.

Loads, injuries, stressful situations, hypertension and other provoking factors can trigger the development of focal changes. The constant overstrain experienced by many able-bodied citizens also plays its unseemly role.

Enhanced work of the brain against the background of what is available in youth, as well as ischemia in old age, can equally lead to the occurrence of foci of dystrophic changes with all the ensuing consequences. And from this it follows that timely and properly organized rest is a very important part of the prevention of the described pathology.

What diseases are accompanied by dystrophic changes in the brain

A focal change in the substance of the brain of a dystrophic nature, as a rule, is provoked by very common disorders in the functioning of blood vessels. These include:

• vasomotor dystonia,
• atherosclerosis,
• arterial hypertension,
• vascular aneurysm in the head and,
• cardio-cerebral syndrome.

The diseases are also accompanied by the described irreversible changes in the brain - everyone knows the problems caused by Parkinson's, Alzheimer's or Pick's disease.

How is the diagnosis made?

The diagnosis of "focal change in the substance of the brain of a dystrophic nature" is rather difficult to establish. This requires the identification of signs of the pathologies listed above and the exclusion of other somatic diseases and possible neuroses. By the way, people with diabetes and rheumatism are also at risk.

The doctor must assess the patient's condition, and also carry out necessary examinations. The most accurate indications are given by an MRI study, where it is possible to identify lesions, as well as their size and localization. Tomography makes it possible to determine changes in the density of brain tissue even in the initial stage of the disease. Correct reading of the MRI results is an important step in the beginning of the treatment of the described problem.

Focal change in the substance of the brain of a dystrophic nature: treatment

As mentioned earlier, the exact cause of the named pathology has not yet been established, unfortunately. And the diseases diagnosed together with it are rather factors that only provoke the onset of its development or enhance processes that have already begun, and not the main cause of the onset of the disease.

Therefore, its treatment consists mainly in normalizing the patient's daily regimen and in a proper diet, including foods that contain organic acids (baked and fresh apples, cherries, sauerkraut), as well as seafood and walnuts. The use of hard cheeses, cottage cheese and milk will have to be limited, since an excess of calcium causes difficulty in oxygen metabolism in the blood, and this supports ischemia and single focal changes in the substance of the brain of a dystrophic nature.

In addition, the patient cannot do without symptomatic therapy, which involves the appointment of drugs that affect cerebral circulation and reduce blood viscosity, taking analgesics, sedatives and B vitamins. However, this is a separate and rather extensive topic.

In particular, this concerns circulatory disorders in the vascular system of the brain and spinal cord.

The system of regulation of cerebral circulation is a physiological mechanism that is aimed at maintaining a constant level of blood circulation during various changes in systemic blood flow and which compensates for changes in the chemistry of the environment or blood surrounding the vessels.

Violation of the blood supply to any area of ​​the brain usually leads to brain damage, while its severity is determined by the level of decrease in cerebral blood flow. The area of ​​the brain in which the level of blood flow becomes less than 10 ml / 100 g per minute is irreversibly damaged, and destructive changes in the brain tissues develop instantly - within 5-10 minutes.

There are many different causes leading to impaired cerebral circulation. The severity and localization of changes in the brain tissues, the area of ​​blood supply to the damaged vessel, the mechanisms that give rise to circulatory disorders, the individual characteristics of the patient - all these changes in the brain tissues are called morphological signs of the disease. They are determined by MRI. Carefully considering these morphological features, among them one can single out cerebrovascular accidents of diffuse and focal nature.

Focal changes in the substance of the brain are diseases that reveal lesions not of the entire brain, but only of part or separate parts. Such diseases include cerebral infarction, hemorrhagic stroke, intrathecal hemorrhages. The very nature of the disease can be of different types: postischemic, dystrophic and dyscirculatory are distinguished. It is the latter that will be discussed.

- this is the name of diseases that are closely associated with chronic and slowly progressive disorders of cerebral and spinal circulation. Such diseases are quite difficult. Usually they are accompanied by dizziness, headaches, noise in the head and ears, sleep disturbances, decreased performance.

Focal changes of dyscirculatory nature on initial stages are quite difficult to detect. This is due to the fact that the condition does not have a pronounced symptomatology: as a rule, there are only scattered microsymptoms. Such focal changes in the substance of the brain are usually accompanied by the following diseases: atherosclerosis, arterial hypertension, neurosis, and vasomotor dystonia.

In other words, in simpler terms, focal lesions of the brain substance of a dyscirculatory nature are lesions of individual parts of the brain due to impaired blood supply and impaired blood circulation.

MRI for focal brain lesions

focal lesions Focal lesions of the brain can be caused by trauma, infectious disease, vascular atrophy, and many other factors. Often, degenerative changes are accompanied by problems associated with a violation of the normal functions of life and coordination of human movement.

MRI in focal lesions of the brain helps to identify the problem in the early stages, coordinate drug therapy. If necessary, based on the results of the examination, minimally invasive surgery can be prescribed.

Signs of focal lesions

All violations of the activity of the brain are reflected in the natural daily functions of human life. The location of the lesion affects the work internal organs and muscular system.

A change in vascular genesis can lead to mental disorders, cause an increase in blood pressure, stroke, and other unpleasant consequences. On the other hand, subcortical foci may not have clinical manifestations and be asymptomatic.

One of the clear signs of the presence of a focal lesion is:

• Hypertension - lack of oxygen supply to the brain caused by vascular degeneration leads to the fact that the brain speeds up and increases blood circulation.

Signs of single focal changes in the substance of the brain of a dyscirculatory nature on magnetic resonance imaging mean that the patient has certain deviations in the work of the vascular system. Most often it is associated with hypertension. The attending physician will provide the diagnosis and explanation of the results of the study.

The picture of focal changes in the substance of the brain of a dystrophic nature is observed, according to various sources, from 50 to 80% of all people as they age. Ischemia, as a result of which the normal blood supply stops, causes a provoking change in soft tissues. Resonance tomography helps to identify the causes of disorders and conduct a differential analysis of the disease.

Small focal changes that do not cause concern at first can eventually cause a stroke. In addition, foci of increased echogenicity of vascular origin may indicate an oncological cause of disorders.

Timely identification of the problem helps to prescribe the most effective therapy. The focus of discirculatory genesis, clearly visible on MRI, may indicate the following pathologies:

• In the cerebral hemispheres - indicates the following possible causes: blocking the blood flow of the right vertebral artery through a congenital anomaly or atherosclerotic plaque. The condition may be accompanied by a hernia of the cervical spine.

If the conclusion of the MRI indicates the diagnosis: "signs of multifocal brain damage of a vascular nature" - this is a reason for certain concerns. The attending physician will be required to establish the cause of the changes and determine the methods of conservative and restorative therapy.

On the other hand, microfocal changes occur in almost every patient after 50 years. Foci are visible in the angiography mode, if the cause is a violation in the genesis.

If a focus of a dystrophic nature is detected, the therapist will definitely prescribe the collection of a general history of the patient. In the absence of additional reasons for concern, it will be recommended to regularly monitor trends in the development of pathology. Substances may be prescribed to stimulate circulation.

Changes in the substance of the brain of a dyscirculatory-dystrophic nature indicate more serious problems. Pressure and lack of circulation can be caused by trauma or other causes.

Signs of small-focal brain damage with vascular etiology of moderate expansion can cause the diagnosis of encephalopathy, congenital and acquired. Some medical preparations can only exacerbate the problem. Therefore, the therapist will check the relationship between medication and ischemia.

Any pathological and degenerative changes should be well studied and verified. The cause of the focal lesion was determined, and according to the results of MRI, prevention or treatment of the detected disease was prescribed.

Question-Answer: Vascular Genesis

The MRI concluded #8212; MR picture of single focal changes in the substance of the brain, probably of a dystrophic nature. Hello! Mom did an MRI in the conclusion it is written. multi-focal lesion of the white matter of the brain is most likely of vascular origin.

Focal brain lesions can be caused by trauma, infectious disease, vascular atrophy, and many other factors. MRI in focal lesions of the brain helps to identify the problem in the early stages, coordinate drug therapy. All violations of the activity of the brain are reflected in the natural daily functions of human life.

A change in vascular genesis can lead to mental disorders, cause an increase in blood pressure, stroke, and other unpleasant consequences. Hypertension #8212; the lack of oxygen supply to the brain caused by vascular degeneration leads to the fact that the brain speeds up and increases blood circulation. Pain syndrome #8212; chronic headaches, migraines may indicate the need for a general examination of the patient.

Signs of focal lesions

Small focal changes that do not cause concern at first can eventually cause a stroke. In addition, foci of increased echogenicity of vascular origin may indicate an oncological cause of disorders. Multiple focal changes in the substance of the brain indicate the presence serious deviations in genesis.

If the conclusion of the MRI indicates the diagnosis: “signs of multifocal brain damage of a vascular nature” #8212; this is cause for some concern. Changes in the substance of the brain of a dyscirculatory-dystrophic nature indicate more serious problems. Signs of small-focal brain damage with vascular etiology of moderate expansion can cause the diagnosis of encephalopathy, congenital and acquired.

The cause of the focal lesion was determined, and according to the results of MRI, prevention or treatment of the detected disease was prescribed. Conclusion: MR-picture of a single focus of the left frontal lobe, external hydrocephalus. But what about the headache that does not go away for so long, and the conclusion of the MRI about hydrocephalus? If the age is advanced, then these may be age-related changes in vascular origin, if young, it may be a sign of a demyelinating disease.

Carrying out diagnostics of changes

And it is already written there: there are small focal changes less than 3x in the right frontal lobe. Most likely of vascular origin. Hello Irina! Hydrocephalus formed when a cyst blocked the ducts of the brain, which led to a violation of the circulation of cerebrospinal fluid. Hello, please help me to decipher the MRI of the brain. 24 years old terrible headaches for 3 years can last for 2 weeks without stopping.

Hello! The guy, 23 years old, had a concussion as a result of an injury. Conclusion: MR-picture of a single focus in the white matter of the frontal lobe on the left, most likely of posthypoxic origin.

Often, degenerative changes are accompanied by problems associated with a violation of the normal functions of life and coordination of human movement. The location of the lesion affects the functioning of the internal organs and the muscular system. On the other hand, subcortical foci may not have clinical manifestations and be asymptomatic. Ischemia, as a result of which the normal blood supply stops, causes a provoking change in the soft tissues.

In the cerebral hemispheres #8212; indicates the following possible causes: blockage of the flow of the right vertebral artery through a congenital anomaly or atherosclerotic plaque. Fears are caused by a tendency to increase the area of ​​the lesion, as well as accompanying changes with impaired motor functions. It can be caused both by a state before a stroke, and senile dementia, epilepsy and many other diseases, the development of which is accompanied by vascular atrophy.

The attending physician will be required to establish the cause of the changes and determine the methods of conservative and restorative therapy. Substances may be prescribed to stimulate circulation.

Pressure and lack of circulation can be caused by trauma or other causes. Any pathological and degenerative changes should be well studied and verified. It is beneficial for them to have many patients, otherwise what are the doctors for? Perhaps this attitude depends on their salary and the health care system.

Is it dangerous? what are the consequences please

These are the doctors! I can indicate the names of doctors and the place of their reception! Good time of the day! Here I am writing, and I myself have terrible headaches that have not stopped for a whole month, day after day. Constant dizziness. Hypertension has never been (working pressure /). no strokes, no chronic diseases, mental and nervous work ..

I am 66 years old. Hypertension for 20 years already. About 5-6 years ago, I once felt a severe headache. She didn’t attach much importance to it, because she attributed everything to meteorological dependence. Of course, the headache appeared more often, but less intense. I confess that I am a very emotional person, quick-tempered, and in past life there were a lot stressful situations.

With great difficulty I asked for a referral for an MRI, I waited a month for this examination and this is the result. As I understand it, this is all from pain in the spine. The doctor can clarify the cause of headaches, determine the treatment tactics and predict the course of the disease only after a full face-to-face consultation.

Strokes #8212; clearly defined focal changes in the brain of a vascular nature on MRI make it possible to establish a pre-stroke state and prescribe appropriate therapy. Hello, I did an MRI. Diagnosis: MR picture of changes in signals from the substance of the brain. It is necessary to differentiate between changes of a vascular nature and a demyelinating nature.

Focal changes in the white matter of the brain

The human body is not eternal and with age it develops various pathological processes. The most dangerous among them are focal changes in the substance of the brain of a discirculatory nature. They occur as a result of impaired cerebral blood flow. Such a pathological process is manifested by a number of neurological symptoms and is characterized by a progressive course. Bring back the lost nerve cells it will no longer work, but you can slow down the course of the disease or even prevent its development.

Causes and signs of pathology

What to do with a focal change in the substance of the brain should tell the doctor, but the patient himself can suspect the presence of pathology. The disease often has a postischemic origin. It is characterized by a violation of blood flow in one of the sections of the hemisphere (hemisphere). It is difficult for some people to understand what it is, therefore, for convenience, the development of changes in the brain substance was divided into 3 stages:

• First stage. At this stage, signs of focal lesions in the substance of the brain do not appear. The patient may feel only slight weakness, dizziness and apathy. Occasionally, sleep is disturbed and headaches bother. Foci of vascular genesis are just emerging and there are small disruptions in the blood flow;
• Second phase. As the pathology develops, the course of the disease worsens. This manifests itself in the form of a migraine, a decrease in mental abilities, ringing in the ears, outbursts of emotions and a disorder in coordination of movements;
• Third stage. If the disease has reached this stage, then focal changes in the white matter of the brain have irreversible consequences. Most of the neurons die and the patient's tone rapidly decreases. muscle tissue. Over time, symptoms of dementia (dementia) appear, the sense organs cease to perform their functions, and the person completely loses control over his movements.

Subcortical lesions in the white matter, localized under the cerebral cortex, may not appear at all for a long time. Diagnosis of such failures is mostly accidental.

Changes in the white matter of the frontal lobes are manifested much more actively and mainly in the form of a decrease in mental abilities.

At-risk groups

If there are no signs of the disease, it is advisable to find out what risk groups this disease has. According to statistics, focal lesions often occur in the presence of such pathologies:

• Atherosclerosis;
• High pressure;
• VVD (vegetovascular dystonia);
• Diabetes;
• Pathology of the heart muscle;
• Constant stress;
• Sedentary work;
• Abuse of bad habits;
• Overweight.

Damage to the white matter of the brain of vascular origin may occur due to age-related changes. Usually there are small single foci in people after 60 years.

Dystrophic nature of damage

In addition to damage caused by vascular genesis, there are other types of disease, for example, single focal changes in the substance of the brain of a dystrophic nature. This type of pathology occurs due to lack of nutrition. The reasons for this phenomenon are as follows:

• Weakened blood supply;
• Osteochondrosis of the cervical region in the acute stage;
• oncological diseases;
• Head injury.

Damage to the substance of the brain of a dystrophic nature usually manifests itself due to a lack of nutrition of the brain tissues. The patient has the following symptoms:

• Decreased brain activity;
• dementia;
• Headaches;
• Weakening of muscle tissue (paresis);
• Paralysis of certain muscle groups;
• Dizziness.

Diagnostics

In most people, with age, focal changes in the substance appear due to tissue degeneration or due to disruptions in the blood flow. You can see them using magnetic resonance imaging (MRI):

• Changes in the cortex hemispheres brain. Such a focus occurs mainly due to blockage or clamping of the vertebral artery. This is usually associated with congenital anomalies or the development of atherosclerosis. In rare cases, along with the appearance of a focus in the cerebral cortex, a vertebral hernia occurs;
• Multiple focal changes. Their presence usually indicates a pre-stroke condition. In some cases, they can prevent dementia, epilepsy and other pathological processes associated with vascular atrophy. If such changes are detected, a course of therapy should be started urgently to prevent irreversible consequences;
• microfocal changes. Such damage is found in virtually every person after years. You can see them with the use of a contrast agent only if they have a pathological nature of occurrence. Small-focal changes are not particularly evident, but as they develop, they can cause a stroke;
• Changes in the white matter of the frontal and parietal lobes subcortically and periventricularly. This type of damage occurs due to constantly elevated pressure, especially if a person has had a hypertensive crisis. Sometimes small single foci are congenital. The danger arises from the growth of lesions in the white matter of the frontal and parietal lobes subcortically. In such a situation, the symptoms gradually progress.

If a person is at risk, then an MRI of the GM (brain) should be done once a year. Otherwise, it is advisable to do such an examination every 2-3 years for prevention. If MRI shows a high echogenicity of the focus of disculatory genesis, then this may indicate the presence of an oncological disease in the brain.

Methods of dealing with pathology

Gradually affecting human brain tissue, the disease can cause irreversible consequences. To prevent changes in the white matter of the brain of a vascular nature, it will be necessary to stop the emerging symptoms and improve blood flow with the help of medications and physiotherapy. Treatment should be comprehensive, which means you will have to change your lifestyle. To do this, you will have to follow these rules:

• Active lifestyle. The patient should move more and play sports. After eating, it is advisable to go for a walk and do the same before going to bed. Water treatments, skiing and running are good. Treatment with an active lifestyle improves general state and also strengthens the cardiovascular system;
• Properly formulated diet. For successful treatment, you will have to give up alcoholic beverages and reduce the consumption of sweets, conservation, as well as smoked and fried foods. You can replace them with boiled food or steaming. Instead of purchased sweets, you can cook a homemade pie or eat fruit;
• Avoidance of stress. Constant mental stress is one of the causes of many diseases, so it is advisable to relax more and not overwork;
• Healthy sleep. A person should sleep at least 6-8 hours a day. In the presence of pathology, it is desirable to increase the sleep time by 1-2 hours;
• Annual survey. If a change in the white matter of the brain is diagnosed, then the patient should undergo an MRI 2 times a year. It is imperative to follow all the recommendations of the doctor and take the necessary tests on time.

Treatment of focal changes usually consists of lifestyle changes and the elimination of the cause of their development. It is desirable to detect the problem immediately in order to be able to slow it down. For this, a complete examination should be carried out annually.

Focal changes in the substance of the brain of a dyscirculatory nature

Without exaggeration, the brain can be called the control system of the entire human body, because different parts of the brain are responsible for breathing, the functioning of internal organs and sensory organs, speech, memory, thinking, and perception. The human brain is capable of storing and processing vast amounts of information; At the same time, hundreds of thousands of processes that ensure the vital activity of the organism take place in it. However, the functioning of the brain is inextricably linked with its blood supply, because even a slight decrease in the blood supply to a certain part of the brain substance can lead to irreversible consequences - the mass death of neurons and, as a result, severe diseases of the nervous system and dementia.

Causes and symptoms of focal changes of a dyscirculatory nature

The most common manifestations of impaired blood supply to the brain are focal changes in the substance of the brain of a dyscirculatory nature, which are characterized by a violation of blood circulation in certain areas of the medulla, and not in the entire organ. As a rule, these changes are a chronic process that develops over a fairly long time, and in the early stages of this disease, most people cannot distinguish it from other diseases of the nervous system. Doctors distinguish three stages in the development of focal changes of a dyscirculatory nature:

1. At the first stage, in certain areas of the brain, due to vascular diseases, a slight violation of blood circulation occurs, as a result of which a person feels fatigue, lethargy, apathy; the patient has sleep disturbances, periodic dizziness and headaches.
2. The second stage is characterized by a deepening of vascular lesions in the area of ​​the brain, which is the focus of the disease. Symptoms such as decreased memory and intellectual abilities, impaired emotional sphere, severe headaches, tinnitus, and coordination disorders indicate the transition of the disease to this stage.
3. The third stage of focal changes in the substance of the brain of a dyscirculatory nature, when a significant part of the cells died in the focus of the disease due to impaired blood circulation, is characterized by irreversible changes in the functioning of the brain. As a rule, in patients at this stage of the disease is significantly reduced muscle tone, there is practically no coordination of movement, signs of dementia (dementia) appear, and the senses may also fail.

Categories of people prone to the appearance of focal changes in the substance of the brain

To avoid development this disease, you need to carefully monitor your well-being, and when the first symptoms appear, indicating the possibility of a focal change in the brain substance of a dyscirculatory nature, immediately contact a neurologist or neuropathologist. Since this disease is quite difficult to diagnose (a doctor can make an accurate diagnosis only after an MRI), doctors recommend that people predisposed to this disease undergo a preventive examination by a neurologist at least once a year. The following categories of people are at risk:

• suffering from hypertension vegetovascular dystonia and other diseases of the cardiovascular system;
• patients with diabetes;
• suffering from atherosclerosis;
• having bad habits and overweight;
• leading a sedentary lifestyle;
• in a state of chronic stress;
• elderly people over the age of 50.

Focal changes of a dystrophic nature

In addition to changes in the dyscirculatory nature, a disease that has similar symptoms, are single focal changes in the substance of the brain of a dystrophic nature due to a lack of nutrients. This disease affects people who have experienced a head injury, suffering from ischemia, cervical osteochondrosis in the acute stage, and patients who have been diagnosed with benign or malignant tumor brain. Due to the fact that the vessels supplying a certain part of the brain cannot fully perform their functions, the tissues in this area do not receive all the necessary nutrients. The result of such a “starvation” of nerve tissues is headaches, dizziness, a decrease in intellectual abilities and performance, and in the final stages dementia, paresis, and paralysis are possible.

Despite the seriousness of these diseases and the difficulty in diagnosing them, each person can significantly reduce the risk of focal changes in the brain substance. To do this, it is enough to refuse bad habits, lead a healthy and active lifestyle, avoid overwork and stress, eat wholesome and healthy food and undergo a preventive medical examination 1-2 times a year.

Dyscirculatory changes in the brain

Currently, neurological diseases associated with impaired blood supply to the central nervous system are becoming more common. Circulatory failure leads to serious consequences and affects normal life.

The trend towards an increase in the number of neuropathologist patients who are diagnosed with dyscirculatory changes in the brain tends to increase and rejuvenate the incidence.

What it is

Dyscirculatory changes in the brain, what it is, is a multi-focal disease of the central nervous system that affects the medulla, characterized by a chronic course with slow development and subsequent severe course illness.

The blood circulation of the tissue areas of the brain is disturbed in the form of small foci; according to the level of such changes, three stages of dyscirculatory changes are distinguished:

• The first stage is the process of tissue changes associated with a slight pathology of the vascular system of the brain, which appeared as a result of diseases of the circulatory system. Symptoms are mild, it is unlikely to diagnose discirculatory anomalies;
• The second stage is the process of death of nerve cells and tissues of the affected area of ​​the brain, associated with a significant deterioration in the blood supply to the head. The symptomatic picture has a vivid expression, the patient's condition worsens significantly;
• The third stage is the last stage, in which most of the cells of the affected area of ​​the brain died, pathological changes begin in the brain with a violation of many vital functions. Symptoms are severe: from complete loss of coordination of movements to a significant decrease in mental activity.

Reasons for the appearance

Dyscirculatory changes in the brain are primarily associated with impaired blood circulation in the cerebral vessels. Therefore, the causes of the appearance of focal lesions of the medulla include:

• Violation of the functions of blood flow in osteochondrosis or trauma of the cervical spine;
• Hypertonic disease;
• Diabetes;
• Vegetative-vascular dystonia;
• Violation of the hormonal background;
• encephalopathy;
• Atherosclerotic changes in the circulatory system;
• Diseases of a cardiovascular nature;
• Wrong lifestyle: smoking, drinking alcohol, inactivity;
• Excess weight;
• oncological diseases;
• Inflammatory, infectious diseases brain;
• hereditary diseases circulatory system;
• Depressive states;
• Injury to the skull and brain of varying degrees;
• Age category of persons over fifty years.

Signs of discirculatory anomalies

The symptomatic picture of this neurological disease appears at the first stage. It is hardly noticeable, as there are small violations in everyday life, which often come down to:

• fatigue;
• sleep deprivation;
• lethargy;
• Rare headaches accompanied by dizziness;
• Feelings and stress.

At the second stage of the disease can be distinguished as signs:

• Minor psychosomatic disorders;
• Sensation of noise, whistling, congestion in the ears;
• Temporary loss of hearing, vision;
• Decreased intellectual activity;
• cognitive impairment;
• Increased blood pressure;
• Strokes of varying severity and etiology;
• Degeneration of cerebral vessels;
• epileptic seizures;
• Ischemic tissue damage;
• The pain in the head becomes chronic;
• The contraction of muscle tissue occurs involuntarily, there is a violation of coordination of movements, rigidity of muscle fibers;
• Other signs of the pathology of the vascular system in the brain: a feeling of a veil before the eyes, instability in space, staggering, swaying to one or both sides of the body, dizziness when the body moves or when its body is raised to a horizontal position.

Diagnostics

The pathology of the brain tissue at the first stages is poorly diagnosed, since the patient rarely comes to the doctor's office with his complaints.

With obvious manifestations of symptoms, the patient is referred by the therapist for a consultation with a neuropathologist.

The neurologist conducts an anamnesis, an external examination for the presence of neuropsychological abnormalities, and a check of reflex function. Based on complaints and examination, the doctor decides how the examination will be carried out:

• Biochemical blood test, coagulogram, for sugar, for cholesterol;
• Analysis of the state of fat metabolism;
• Measurement of blood pressure, its daily monitoring;
• Doppler check of the vascular system of the head and cervical region;
• Magnetic resonance imaging;
• electrocardiography;
• If necessary, consultation of doctors: cardiologist, nephrologist, ophthalmologist.

Treatment

Based on the tests and diagnostics, the neuropathologist prescribes treatment. An individual complex of therapy is developed, based on the general condition of the patient, the presence of allergies, the tolerance of these drugs or other drugs.

The main emphasis in therapy is on the treatment of a concomitant disease that caused the occurrence of pathological changes in the brain.

• Restoration and improvement of the activity of the circulatory system of the cerebral department;
• Supports the functioning of healthy nerve cells;
• Providing brain tissue with sufficient oxygen and nutrients;
• Restoration of the normal level of hemodynamics: antagonists, calcium blockers, phosphodiesterase inhibitors;
• Suspension of cognitive pathological processes;
• Improving the functions of the vestibular apparatus;
• With a clear violation of the patency in the arteries due to atherosclerotic processes, ischemia or stroke, a decision is made on surgical intervention;
• Sedative sedative effect;
• Expansion of blood vessels;
• Improvement of vascular tone;
• Strengthening the nervous system containing phytoextracts;
• Enrichment of the brain with essential minerals and vitamins.

Diet

• Fresh vegetables and fruits rich in vitamins: C, group B, PP, as well as minerals: magnesium, potassium;
• Onions, garlic for splitting excess fats;
• Cereals to strengthen the arteries;
• If there is no allergy, a Mediterranean diet is possible.

Prevention

Preventive measures should be applied absolutely healthy people and when the first signs of dyscirculatory anomalies appear:

• Compliance with the daily routine;
• Adequate physical exercise;
• Complete rest;
• Healthy lifestyle;
• Gymnastics, sports;
• Proper, balanced nutrition;
• Professional examination by a neurologist once a year.

Focal changes in the substance of the brain of a dyscirculatory nature

One of the most important topics in medicine are those that are directly related to brain diseases. In particular, one of the serious points is the violation of blood circulation in the vascular system of the spinal cord and brain. There are many different reasons that lead to impaired circulation.

The location and severity of various changes in the brain tissues in patients with diseases associated with cerebrovascular accident, which can be determined by its underlying disease, the area of ​​blood supply of the damaged vessel, various mechanisms that give rise to circulatory disorders, as well as the individual characteristics of the patient - such as history previous diseases, age, complexion and others. These changes are called morphological signs of the disease and are determined using MRI. Considering carefully the morphological signs, one can distinguish among them cerebrovascular accidents of focal and diffuse characters.

Focal changes in the substance of the brain are diseases that reveal lesions not of the entire brain, but only of its individual parts, or parts. These include diseases such as hemorrhagic stroke, cerebral infarction, intrathecal hemorrhages. The nature of the disease can be of various types, here they distinguish dystrophic, postischemic, and also dyscirculatory. That's what I wanted to focus on.

Focal changes in the substance of the brain of a dyscirculatory nature are diseases that are tightly associated with chronically slowly progressive disorders of the spinal and cerebral circulation. These are quite severe diseases that are accompanied by headaches, dizziness, noise in the ears and head, decreased performance and sleep disturbances. In the initial stages, they are not easily detected due to the fact that patients do not have pronounced symptoms - usually, it is scattered microsymptoms. Focal changes in the substance of the brain of a dyscirculatory nature usually accompany diseases such as atherosclerosis, arterial hypertension, vasomotor dystonia, and nervosa.

In simple terms, then: this is a lesion of certain parts of the brain due to the fact that the blood supply and blood circulation are disturbed.

Causes of focal changes in the substance of the brain of a dyscirculatory nature

The regulation of blood supply in the human head is special mechanism physiology. The functions of this mechanism are aimed at supporting and normalizing blood circulation in the brain in situations where the systemic blood flow changes for any reason. This compensates for failures in the chemical composition of the environment that surrounds the vessels, as well as blood. If blood supply is disturbed in some part of the brain, then focal changes in the substance of the brain of a dyscirculatory nature may occur. At this time, there may be a loss of brain tissue function, and the severity of the lesion is determined by how much the blood flow has decreased.

There can be many reasons that can lead to failures in the cerebral blood flow system. The general picture of the localization of structural changes inside the brain tissues, their severity; mechanisms of damage that give rise to the development of disorders; the area of ​​blood flow to the damaged vessel, the individual characteristics of the organism - all such deviations in the brain structures are related to morphological features this diagnosis. These signs of damage can be determined on an MRI. This will help to highlight the places of circulatory failures, both local and widespread.

Local, or focal, changes in the white matter of the brain are diseases that are dysfunctions not of the whole brain, but only of a certain small part or several parts. A heart attack in the brain would be such a lesion. In addition, a stroke, for example, of a hemorrhagic type, as well as a hemorrhage under the membrane. The nature and course of the disease may also differ:

1. Dystrophic type of disease;
2. Discirculatory type of diagnosis;
3. Postischemic type of condition.

Single focal changes in the substance of the brain of a dyscirculatory nature are diagnoses that are quite closely associated with chronic lesions of the cerebral and spinal blood flow. Such disorders develop and progress slowly, but very hard.

Focal changes in the brain are very difficult to detect at their primary stages of development. Such conditions do not have a good and vivid expression of symptoms. All symptoms manifest themselves in the form of microsymptoms of a diffuse nature. This type of single focal changes in the substance of the brain of a dyscirculatory nature most often appear together with concomitant diseases, for example, such as neuroses, atherosclerosis, vegetovascular dystonia, and arterial hypertension.

In general, if we give a simple definition, then such foci in the white matter in some areas and in certain places of the human brain appear due to vascular genesis, disturbances in the blood supply and blood circulation through the vessels of the brain.

Signs and symptoms of focal lesions in the brain

Any type and kind of brain damage, as well as functional disorders of its structure and activity or the work of body systems that are closely related to it, are necessarily reflected in the daily activities of a person, his behavior, functions. Also, the very location of the lesion can very noticeably affect the functioning of the body's organ systems, as well as the proper functioning of the musculoskeletal and musculoskeletal systems.

In addition to pathologies that were caused by vascular genesis, other types of diagnoses may also occur, including single focal changes in the substance of the brain of a dystrophic nature. This kind of pathology can most often occur with insufficient supply of nutrients and oxygen to the brain tissue.

The reasons for this phenomenon:

1. Oncological type of tissue damage;
2. Insufficient blood supply to a certain area of ​​\u200b\u200bthe tissue;
3. Injury to the head and brain tissue;
4. Acute stage of cervical osteochondrosis.

When, due to vascular genesis, small focal changes in the brain occur in a person, the following symptoms are usually observed:

1. Significant decrease in brain activity;
2. Pain in the head;
3. dementia;
4. Frequent dizziness;
5. Paresis of muscle tissue, weakening;
6. Local, partial paralysis of some muscle groups.

In addition, changes in blood circulation around the substance of the brain of a dystrophic nature can also lead to a disorder of the human psyche. In view of vascular degeneration, blood pressure may increase, a stroke may occur, as well as hyperintense brain phenomena. But it can also happen that subcortical lesions may not be symptomatic.

The main signs of the presence of focal disorders

One of the main symptoms is hypertension. After all, if the blood circulation in the brain is disturbed, then it will suffer from a lack of oxygen, and this, in turn, will immediately lead to an acceleration of signals about the supply of blood to the brain, thereby increasing blood pressure. In addition, there may be epileptic seizures in a sick person. A variety of mental disorders are also the main symptom of focal brain damage. After all, with pathological phenomena in the subarachnoid spaces, hemorrhages often occur. This can lead to formations in the fundus, darkening and other symptoms that appear in the fundus. Here, darkenings form very quickly, the vessels around the eye burst and retinal rupture can occur. Based on these signs, it is possible to determine exactly where the multiple foci are located.

A possible stroke or micro-stroke is also the main symptom. Focal changes in the brain are usually clearly visible on MRI, which makes it possible to determine the pre-stroke state. This will allow the doctor to immediately prescribe the right treatment. The most obvious signs of damage can be considered single and multiple, small and large involuntary muscle contractions.

And, of course, pain is no exception. Migraines, frequent and severe headaches clearly indicate disorders of a multifocal nature.

Treatment

Individual changes in the white matter, which are clearly defined on MRI, may mean that the patient has abnormalities in the blood circulation of the brain of vascular origin. Based on these data, the doctor will prescribe an examination that will more clearly show the causes of this situation, and will allow you to prescribe the correct treatment.

To select the treatment of focal changes in the substance of the brain of a dyscirculatory nature, the doctor first prescribes therapy for the disease that led to this alignment. Drugs are prescribed that improve blood circulation between brain structures, oxygen metabolism, reduce blood viscosity, have a sedative and analgesic effect, as well as complexes of vitamins and necessary elements.

In addition, to restore the functions of the white matter of the brain, if possible, the patient is prescribed a strict diet, bed rest and rest. This will help to avoid further changes in the substance of the brain. The patient's regimen should be normalized, it is important to exclude any physical activity, as well as completely review his diet. You should unquestioningly obey the doctor's orders.

Prevention

Prevention of multiple focal changes in the substance of the brain includes:

1. Leading an active lifestyle. After all, movement stimulates the improvement of blood circulation throughout the human body and in the brain, in particular, and thereby reduces the risk of lesions in the brain substance.
2. Proper and rational nutrition.
3. Avoid stress and other nervous situations. After all, a constant nervous tension may be the cause of more than one disease. No need to overwork often, you should rest and relax more.
4. Healthy and sound sleep is always a guarantee of health. You need to spend at least 7-8 hours of sleep per day. If there is insomnia or any other sleep pathology, then sleep time should be increased to 10 hours a day.
5. It is necessary to conduct an examination in the hospital every year to identify hidden pathologies and diseases. If symptoms are found that may indicate changes in the medulla, then an MRI is required 2 times a year, as well as all the necessary tests.

Everyone knows that it is always easier to prevent a problem in advance than to look for the right and correct solution later. Also with health. Easier to hold necessary prevention than to treat the disease.

Focal changes in the substance of the brain of a dyscirculatory nature

Against the background of circulatory insufficiency, focal changes in the substance of the brain of a dyscirculatory nature develop. The brain is supplied with blood from 4 vascular pools - two carotid and two vertebrobasilar. Normally, these pools are interconnected in the cranial cavity, forming anastomoses. These compounds enable the human body to compensate for the lack of blood flow and oxygen starvation for a long time. In areas that experience a shortage of blood, blood flows from other pools by overflow. If these anastomotic vessels are not developed, then they speak of an open circle of Willis. With such a structure of blood vessels, circulatory failure leads to the appearance of focal changes in the brain, clinical symptoms.

Clinical picture

The most common diagnosis in the elderly, made only on the basis of complaints, is dyscirculatory encephalopathy. However, it must be remembered that this is a chronic, steadily progressive circulatory disorder that develops as a result of suffering from brain capillaries, which is associated with the development a large number microstrokes. Focal brain damage can be diagnosed only if certain criteria are met:

• there are signs of brain damage, which can be confirmed objectively;
• constantly steadily progressing clinical symptoms;
• the presence of a direct relationship between the clinical and instrumental picture during additional methods surveys;
• the presence of a cerebrovascular disease in a patient, which is a risk factor for the development of focal brain damage;
• the absence of other diseases with which the origin of the clinical picture could be associated.

Focal changes in the substance of the brain of a dyscirculatory nature are manifested by impaired memory, attention, movement, emotional-volitional sphere.

The main influence on functional state and social adaptation of the patient have cognitive disorders. When there is a focal lesion of the brain substance in the area of ​​the frontal and temporal lobes of the dominant hemisphere, then there is a decrease in the memory of attention, a slowdown in thought processes, a violation of planning and the consistent execution of daily routine work. Cognitive impairments are explained by dystrophy of the brain of vascular origin. With the development of neurodegenerative focal changes in the brain, a person ceases to recognize familiar objects, speech suffers, emotional and personality disorders join. First, asthenic syndrome appears and depressive states responding poorly to antidepressant treatment.

Progressive dystrophic, degenerative disorders lead to the appearance of egocentrism, there is no control over emotions, an inadequate reaction to the situation develops.

Movement disorders are manifested by staggering when walking, coordination disorders, central paresis of varying severity, trembling of the head, hands, emotional dullness and amimia. Steadily progressive focal lesions of the brain lead to the final stage of the disease, when the patient cannot eat due to constant choking. Violent emotions appear, for example, laughter or crying out of place, the voice becomes nasal.

Predisposing factors

Diseases leading to small-focal changes in the substance of the brain include arterial hypertension, stenosing and occlusive vascular lesions, disorders of lipid and carbohydrate metabolism.

The main mechanism for the development of dyscirculatory encephalopathy is manifested by the fact that foci of ischemia and infarction are formed. This is a condition when dystrophic changes begin to develop against the background of oxygen starvation, reduced blood flow, and a slowdown in metabolism. Areas of demyelination, edema, gliosis degeneration, expansion of perivascular spaces appear in the brain. The above factors are the main ones. They explain the existing lesions and the genesis of the brain.

Additional examination methods

The main method for diagnosing this pathology is MRI of the brain, in which hyperintense foci, small heart attacks, postischemic degeneration, and expansion of the ventricular system are determined. The number of heart attacks can be from single to multiple cases, the diameter is up to 2.5 cm. Small focal changes say that this is such a serious lesion that can lead to the patient's disability. It is in this place that blood circulation suffers.

Doppler ultrasound, duplex scanning is used, which can show blood flow disturbance in the form of its asymmetry, stenosis, occlusion of the main vessels, increased venous blood flow, atherosclerotic plaques.

Computed tomography will allow you to see only traces of past heart attacks in the form of gaps filled with liquor, i.e. cysts. Thinning is also determined - atrophy of the cerebral cortex, expansion of the ventricles, communicating hydrocephalus.

Modern approaches to therapy

Treatment should be directed to the underlying disease that led to brain disorders. In addition, it is necessary to use means that prevent the progression of the disease.

AT without fail vascular agents are prescribed, such as pentoxifylline, vinpocetine, cinnarizine, dihydroergocriptine. They have a positive effect on cerebral circulation, normalize microcirculation, increase the plasticity of erythrocytes, reduce blood viscosity and restore its fluidity. These medicines relieve vascular spasm, restore tissue resistance to hypoxia.

As an antioxidant, nootropic, antihypoxic treatment, cytoflavin, actovegin, thioctic acid, piracetam, ginkgo biloba are used.

Treatment with vestibulotropic agents reduces the effects of dizziness, eliminates unsteadiness when walking, and improves the quality of life of patients. Treatment with betahistine, vertigochel, dimenhydrinate, meclozin, diazepam justifies itself.

With high blood pressure, regular monitoring of pressure figures and heart rate and their normalization according to indications is necessary. Aspirins, dipyridamole, clopidogrel, warfarin, dabigatran are used to thin the blood. Statins are used to treat high cholesterol levels.

At present, the focus is on blockers. calcium channels, which, along with the function of normalizing blood pressure, have a neuroprotective effect. Cerebrolysin, cerebrolysate, gliatilin, mexidol restore cognitive functions well.

Neurotransmitters, for example, citicoline, has a nootropic and psychostimulant effect, normalizes memory, attention, improves well-being, and restores the patient's ability to self-service. The mechanism of action is based on the fact that the drug reduces cerebral edema, stabilizes cell membranes,

L-lysine aescinate has anti-inflammatory, decongestant, and neuroprotective properties. Stimulates the secretion of glucocorticoids, restores vascular permeability, tones the veins and normalizes venous outflow.

Selective therapy for cognitive disorders

To restore memory, attention, performance, donepezil is used - a drug that normalizes the metabolism of neurotransmitters, restores the speed and quality of transmission of nerve impulses as intended. Restores daily activity of patients, corrects apathy, thoughtless obsessive actions, eliminates hallucinations.

Galantamine normalizes neuromuscular transmission, stimulates the production digestive enzymes, secretion of sweat glands, lowers intraocular pressure. The drug is used for dementia, dyscirculatory encephalopathy, glaucoma.

Rivastigmine is an effective remedy. But its reception is limited by the presence of gastric ulcer, duodenum, conduction disorder, arrhythmia, bronchial asthma, obstruction urinary tract, epilepsy.

With severe psycho-emotional disorders, antidepressants are used. Well proven in this pathology selective inhibitors serotonin reuptake. These drugs include venlafaxine, milnacipran, duloxetine, sertraline. Drugs of this group in pharmacies are sold only by prescription. The attending physician prescribes these drugs, taking into account the severity of intellectual-mnestic disorders, depression, delusions.

Prevention

Prevention of discirculatory encephalopathy is, first of all, the treatment of the causes that lead to arterial hypertension, stress, diabetes, obesity. In addition to maintaining healthy lifestyle life, normalization of sleep, rest of the work regime, it is necessary to avoid manual therapy on the cervical spine. Unsuccessful tilting of the head and neck can lead to irreversible disruption of blood flow in the vertebrobasilar basin and cause disabling or fatal complications.

If there are signs of increased fatigue, memory loss, attention to working capacity, it is necessary to consult a doctor and perform examinations that will eliminate the violation of blood flow through the vessels supplying the brain. To identify cardiac, pulmonary, endocrine pathology and start treating in a timely manner is the way to success in the fight against dyscirculatory encephalopathy.

As the human body ages, organs and organ systems may begin to work intermittently. Cardiovascular activity worsens over the years, most often due to diffuse and focal disorders of cerebral circulation.

Ischemia, the main characteristic of which is insufficient blood supply to the brain, provokes the appearance of focal changes in the medulla of a dystrophic nature, the occurrence of which becomes possible before and after a stroke, with cervical osteochondrosis in the acute stage and in violation of the patency of one of the four main vessels responsible for the nutrition of the brain, brain stem, cerebellum. The resulting tumor or injury can also lead to similar changes.

They represent a significant violation of the functions of tissues due to their "starvation" (acute lack of nutrients), in which not the brain is completely affected, but only part of it. The negative consequence of this process is that the tissues can no longer perform some of their mandatory functions, as a result of which the affected part of the brain ceases to cope with its tasks.

A person in whose body such processes occur may complain of a severe headache that does not go away for a long time, frequent dizziness, insomnia, a rapid deterioration in performance, not accompanied by any neurological symptoms. Paralysis, paresis, deterioration in coordination of movements, etc. are focal symptoms. Deterioration of memory and intellectual abilities can also accompany focal changes in the substance of the brain of a dystrophic nature.

At primary diagnosis disorders of cerebral circulation to make the correct diagnosis, attention should be paid to the presence of signs of diseases such as vegetovascular dystonia, arterial hypertension, atherosclerosis. It is imperative to exclude any other somatic pathology and neurosis.

MRI for focal brain lesions

MRI in focal lesions of the brain helps to identify the problem in the early stages, coordinate drug therapy. If necessary, based on the results of the examination, minimally invasive surgery can be prescribed.

Signs of focal lesions

All violations of the activity of the brain are reflected in the natural daily functions of human life. The location of the lesion affects the functioning of the internal organs and the muscular system.

• Hypertension - lack of oxygen supply to the brain caused by vascular degeneration leads to the fact that the brain speeds up and increases blood circulation.

Carrying out diagnostics of changes

The picture of focal changes in the substance of the brain of a dystrophic nature is observed, according to various sources, from 50 to 80% of all people as they age. Ischemia, as a result of which the normal blood supply stops, causes a provoking change in the soft tissues. Resonance tomography helps to identify the causes of disorders and conduct a differential analysis of the disease.

Small focal changes that do not cause concern at first can eventually cause a stroke. In addition, foci of increased echogenicity of vascular origin may indicate an oncological cause of disorders.

• In the cerebral hemispheres - indicates the following possible causes: blocking the blood flow of the right vertebral artery through a congenital anomaly or atherosclerotic plaque. The condition may be accompanied by a hernia of the cervical spine.

Single focal changes in the substance of the brain of a dystrophic nature, what is it?

Every person sooner or later begins to grow old. Along with it, the whole body ages. Aging primarily affects the brain. There is a failure in the system of the heart and blood vessels. The cause of such failures is insufficient blood circulation in the brain and spinal cord.

Violation of cerebral circulation is divided into:

1. focal,
2. diffuse.

If a person is ill with ischemia, then local changes occur in the brain gray matter the brain of the head, due to a lack of blood supply to the brain. This condition can be seen after osteochondrosis of the neck of the spine or a stroke, when the arteries of the vessels through which blood enters the brain are disrupted. Changes in the substance of the brain of the head can lead to any injury or tumor.

Focal changes

Violation of the integrity of the brain tissue in any one place is called a focal change in the brain substance of the head of a dystrophic nature. As a rule, these are those parts of the brain that receive practically no nutrients. In this state, tissue processes are reduced, and the affected part of the brain begins to malfunction.

Focal changes in the substance of the brain include:

1. small cysts,
2. Small foci of necrosis
3. gliomesodermal scars,
4. Absolutely insignificant changes in the substance of the brain.

Single focal changes in the substance of the brain of the head of a dystrophic nature give the following symptoms that a person simply cannot help but notice:

• Frequent and severe headache
• paresthesia,
• Dizziness,
• hyperkinesis,
• Paralysis,
• violation of coordination of movements,
• Decreased intelligence
• memory loss,
• Disorders in the emotional sphere,
• sensitivity disorders,
• ataxia,
• Agraphia.

Upon examination, the doctor will have to identify the cause of the appearance of severe changes in the substance of the brain and the accompanying diseases:

1. vasomotor dystonia,
2. Atherosclerosis,
3. Various somatic diseases
4. arterial hypertension,
5. Aneurysm in the vessels of the brain and spinal cord,
6. Cardiocerebral syndrome.

When does the disease appear?

Local focal changes in the substance of the brain of a dystrophic nature occur after seventy years and are characterized by manifestations of senile dementia. With this disease, a thought disorder or dementia occurs. Dominant diseases include:

By the way, single focal changes in the substance of the brain of a dystrophic nature can occur not only in old age, but also in young and middle-aged people. Any infection or mechanical injury can disrupt the integrity or patency of the blood vessels that feed the brain and spinal cord.

How to treat?

In treatment, the main thing is to have time to recognize the disease, when the symptoms of focal changes in the substance of the brain are not yet so pronounced and the process of change can still be reversed. There will be many different therapeutic measures aimed at improving the blood supply to the brain: normalizing the regime of rest and work, choosing the right diet, using sedatives and analgesics. Drugs that improve the blood supply to the brain will be prescribed. The patient may be offered sanatorium treatment.

Who is susceptible to illness?

Individuals undergo a single focal change in the substance of the brain of the head of a dystrophic nature:

1. Suffering from diabetes,
2. Patients with atherosclerosis
3. Those suffering from rheumatism. Such people need to first cure the main disease, follow special diet, monitor physical activity and, of course, visit a doctor regularly.

Local focal changes in the substance of the brain can be cured if approached in a qualified and timely manner. Unfortunately, only senile changes in the substance of the brain are difficult to treat.

Focal changes in the substance of the brain of a dystrophic nature

Aging, the human body begins to function with interruptions in the work of organs and systems. Most often, the activity of the cardiovascular system worsens, in particular, the blood supply to the brain and spinal cord.

Cerebral circulation disorders are:

• diffuse;
• Focal.

Focal changes in the substance of the brain of a dystrophic nature are disorders that affect not the entire brain tissue, but only certain areas, foci. The functions of the brain tissues are disrupted due to a lack of nutrients that should be supplied to them. As a result of such changes, the entire part of the brain cannot perform its tasks.

Focal changes combine a number of different small changes in tissues of a different nature and degree of prescription, areas of necrosis, medium-sized cysts, gliomesodermal scars.

A number of reasons can cause focal changes in the substance of the brain of a dystrophic nature:

• Ischemia, which is just characterized by a decrease in blood circulation to the brain;
• Cervical osteochondrosis in the acute stage, as well as with a change in the patency of the main vessels that supply blood to the hemispheres, brain stem, cerebellum;
• Head injury;
• Tumor as it grows.

Symptoms of such changes in the human body are severe and prolonged headaches, insomnia, constant dizziness, which do not have neurological symptoms. The memory and intellectual abilities of a person deteriorate, coordination of movements deteriorates, and working capacity decreases. The emotional-volitional sphere suffers, sensitivity decreases. Paresis and paralysis appear.

Diagnosis of cerebrovascular accidents is quite difficult. To make a correct diagnosis, it is initially worth trying to identify signs of atherosclerosis, aneurysms of the vessels of the spinal cord and brain, arterial hypertension, and vasomotor dystonia. It is also necessary to exclude other somatic diseases and possible neuroses.

The treatment is the normalization of the regime of work and rest, the right diet and the appointment of a number of drugs that improve cerebral circulation, as well as analgesics and sedatives. If focal changes are recognized in time, their further development can be stopped or significantly slowed down. What can not be done with the development of senile dementia, the cause of which are atrophic changes in the brain.

Scientists cannot name the exact cause of these problems, one or another external influences play only a provoking, reinforcing role. In rare cases, the disease is associated with heredity. The main factor in this case is the age of the person: these problems occur in older people, progressing over time.

Otherwise, atrophic changes in the brain are also called dementia - a synonym for dementia, a disorder of thought processes. Alzheimer's, Parkinson's, Pick's, Huntington's chorea, and some rarer diseases are atrophic dementias.

Since science finds it difficult to determine the causes of these diseases, their treatment is also difficult. In the sense that the processes in the brain tissues are irreversible, and it is impossible to stop the progressing course. You can only alleviate certain symptoms. For example, with severe excitability, sedatives are prescribed. In general, for such patients it is desirable to organize a fairly active and at the same time calm, measured lifestyle.

When dementia becomes pronounced, the patient needs careful care and constant supervision at home or in hospital.

Currently, such a disease as angiodystonia of cerebral vessels is increasingly being observed not only in adults, but also in children.

The presence of small perineural cysts is observed in approximately 7% of people on our planet. Interestingly, they are more common in women. Briefly def.

Arnold-Chiari anomaly type 1 is detected as a descent of structures located within the posterior cranial fossa into the cavity of the spinal canal.

Numbness of the fingers on the hand is a disorder or loss of skin sensitivity in the form of a sensation of numbness in certain areas, especially on the left.

Focal changes in the substance of the brain of a dystrophic nature

Sooner or later, all people grow old, and the body ages along with them. It primarily affects the heart, brain and spinal cord. If the heart ceases to properly cope with its task - pumping blood - then over time this will affect the state of the brain, the cells of which will not receive enough nutrients to sustain life.

According to various sources, from 50 to 70% of the elderly (over 60 years) suffer from a similar disease.

Symptoms of dystrophy of the substance of the brain

Any disease is better to prevent than to treat later, and for this you need to know its external manifestations (signs) and symptoms.

• First stage. In the first couple, a person feels a little tired, lethargic, dizzy and does not sleep well. This is due to poor blood circulation in the brain. The degree of significance grows along with the development of vascular diseases: cholesterol deposition, hypotension, etc.
• Second stage. At the second stage, the so-called “center of the disease” appears in the brain, the damage to the brain substance deepens due to poor blood circulation. Cells do not receive sufficient nutrition and gradually die off. The beginning of this stage is indicated by memory impairment, loss of coordination, noise or “shooting” in the ears, and severe headaches.
• Third stage. Due to the discircular nature of the course of the last stage, the focus of the disease moves even deeper, the affected vessels bring too little blood to the brain. The patient shows signs of dementia, lack of coordination of movements (not always), dysfunction of the sense organs is possible: loss of vision, hearing, shaking hands, etc.

It is possible to establish the exact change in the substance of the brain using MRI.

In the absence of treatment, over time, diseases such as:

1. Alzheimer's disease. The most common form of degeneration of the nervous system.
2. Pick's disease. A rare progressive disease of the nervous system, manifested by rally.
3. Huntington's disease. genetic disease nervous system. developing rally.
4. Arterial hypertension.
5. Cardiocerebral syndrome (impairment of the basic functions of the brain due to cardiac pathology).

Reasons for change

As already mentioned, the main cause of the manifestation of the disease is vascular damage, which inevitably occurs with age. But for some, these lesions are minimal: small cholesterol deposits, for example, - while for someone they develop into pathology. So, diseases lead to a change in the substance of the brain of a dystrophic nature:

1. Ischemia. This disease is mainly characterized by a violation of the blood circulation of the brain.
2. Cervical osteochondrosis.
3. Tumor (benign or malignant).
4. Severe head injury. In this case, age does not matter.

Risk group

Any disease has a risk group, people who are in it should be extremely careful. If a person has similar diseases, then he is in the primary risk group, if only predispositions, then in the secondary:

• Suffering from diseases of the cardiovascular system: hypotension, hypertension, hypertension, dystonia.
• Patients with diathesis, diabetes mellitus or stomach ulcers.
• Those who are overweight or have an unhealthy eating habit.
• Being in a state of chronic depression (stress) or leading a sedentary lifestyle.
• People are older regardless of gender.
• Those suffering from rheumatism.

How to overcome?

Despite the complexity of the disease and the problems with its diagnosis, each person can avoid such a fate by helping his body fight the signs of old age or the consequences of a serious injury. To do this, follow simple rules.

First, lead a mobile lifestyle. Walk or jog for at least two hours a day. Walk in the fresh air: in the forest, in the park, go out of town, etc. Play outdoor games that correspond to physical abilities: basketball, pioneer ball, volleyball, tennis or table tennis, etc. The more movement, the more actively the heart works, and the vessels become stronger.

Secondly, proper nutrition. Eliminate or minimize the consumption of alcohol, excessively sweet and salty foods and fried foods. This does not mean that you have to keep yourself on the strictest diet! If you want meat, then you don’t need to fry it or drip sausage, it’s better to boil it. Same thing with potatoes. Instead of cakes and pastries, you can treat yourself to homemade apple and strawberry pies from time to time. All harmful dishes and products can be replaced with their equivalents.

Thirdly, avoid stressful situations and overwork. The mental state of a person directly affects his health. Do not overwork yourself, rest, if you are tired, sleep at least 8 hours a day. Do not overwork yourself with physical activity.

Fourth, 1-2 times a year, go through a medical examination to monitor the condition of the body. Especially if you are already undergoing treatment!

It is best not to try to help your body with “home methods”: drink medicines on your own, inject injections, etc. Follow the instructions of the doctor, go through the procedures that he will prescribe. Sometimes, to determine the accuracy of the diagnosis, it is necessary to undergo many procedures, taking tests is a normal situation.

A responsible doctor will never prescribe medication unless he is sure of the accuracy of the diagnosis.

Types, causes, treatment of focal changes in the brain of a vascular nature

Each part of the brain performs certain functions - it regulates speech, thinking, balance, attention, controls the work of internal organs. The brain stores and processes an incredible amount of information; at the same time, many processes take place in it that provide a person with normal life activity. The functioning of this entire complex system directly depends on the blood supply. Even a small damage to the vessels leads to serious consequences. One of the manifestations of this pathology are focal changes in the brain.

What pathologies exist

Due to the lack of oxygen in the brain, cell starvation begins (in medicine, this process is called ischemia), causing dystrophic disorders. In the future, these disorders affect areas of the brain that partially or completely lose their natural functions. There are two types of dystrophic disorders:

1. Diffuse, covering the entire brain tissue evenly, without the appearance of pathological areas. They appear due to impaired blood circulation, brain injuries, concussions, inflammation caused by infections. Symptoms of diffuse pathologies are often reduced ability to work, unbearable constant pain in the head, apathy, lethargy, and insomnia.
2. Focal changes in the substance of the brain of a dyscirculatory nature, covering a separate area where blood circulation is disturbed. Foci are single or numerous, randomly scattered throughout the brain tissues. Basically it's sluggishly flowing chronic illness developing over the years.

Among the focal pathologies are often found:

• A cyst is a small cavity filled with fluid. Often does not cause discomfort in patients and pain, but it causes compression of blood vessels and nearby areas of the brain.
• Necrotic necrosis affecting areas of the brain due to impaired transport of nutrients. Dead cells that form dead zones do not perform their functions and are not restored in the future.
• Brain scar and hematoma that occurs after a severe injury or concussion. These focal changes in the brain lead to small structural damage.

Stages of development of dyscirculatory changes

There are three stages of this pathology:

1. Initially, dyscirculatory changes are characterized by a slight disturbance in the movement of blood in certain brain areas. Because of this, the patient quickly gets tired, often experiencing bouts of circling and headache.
2. When the disease develops and flows into the second stage, the lesion is aggravated. Memory deteriorates, intellectual abilities decrease. The person becomes extremely irritable, emotional. Coordination of movements worsens, tinnitus appears.
3. At the third stage, a significant part of the neurons die. At the same time, the muscles noticeably suffer, obvious signs of dementia appear, and the organs of touch and senses may fail.

The location of focal diffuse changes of a vascular nature in the brain and spinal cord determines how the functionality of organs that are sensitive to such disorders changes.

Symptoms of focal lesions

Focal lesions of the brain are caused by damage to blood vessels, which lose their elasticity with age. In some, this manifests itself minimally, while in others, violations flow into pathological form. Can appear:

• High blood pressure, provoked by a lack of oxygen due to the degenerative state of the cerebral vessels.
• Epileptic seizures, in which a person should not put metal objects into his mouth, pour water on him, beat him on the cheeks, etc.
• Mental disorders, memory impairment, distorted perception of reality, atypical behavior.
• Stroke or pre-stroke condition, which can be identified on CT or MRI.
• Increasing throbbing headache in the back of the head, eye sockets, superciliary areas, radiating over the surface of the entire skull.
• Uncontrolled muscle contractions, tremor of the limbs, chin, eyes, neck.
• Tinnitus, ringing, stuffiness leading to nervousness.
• Regular bouts of dizziness leading to nausea and vomiting.
• Photophobia, decreased hearing acuity, blurred vision, double vision, marked visual impairment.
• Constant fatigue, apathy.
• Slurring of speech.
• Sleep disturbance.
• Muscle paresis, pathological reflex reaction of the extremities.

Many people ask what diseases are provoked by focal brain damage, what it is, and why it occurs. It is known that the causes of this disorder may lie in:

• Vascular disorders associated with natural aging, cholesterol accumulation in the walls of blood vessels.
• Osteochondrosis of the neck.
• Oxygen starvation.
• neoplasms.
• Injuries, open and closed injuries heads (here age is not important).

Who is at risk

Any disease has its own risk groups. People belonging to such groups should carefully monitor their health and immediately consult a doctor at the first suspicious symptoms. With focal pathologies, this group includes patients:

• Hypertension, hypotension.
• Diabetes.
• Atherosclerosis.
• Rheumatism.
• obese.
• Sensitive, emotional people living in constant stress.
• Leading a sedentary life.
• Elderly people, regardless of gender (starting a rally).

They also provoke the development of vascular pathologies:

Diagnostics

Focal lesions of the brain are often asymptomatic. Even if there are minor symptoms, patients rarely seek medical attention. It is difficult to identify the pathology. This can be done by undergoing an MRI scan. It allows you to see even the smallest degenerative lesions that can lead to stroke or cancer.

MRI may indicate such disorders:

• With changes in the hemispheres, clogging of the arteries is possible due to a hernia of the spinal column, abnormal intrauterine development, and atherosclerotic plaques.
• Violations in the white matter of the frontal region are characteristic of hypertension (especially after exacerbation), congenital developmental anomalies, as life-threatening progresses.
• Multiple foci entail a pre-stroke state, senile dementia, episyndrome.

Numerous small foci threaten life, cause many serious illnesses. They are mostly found in older people.

Treatment

The doctor explains to patients why brain dystrophy is dangerous, what it is and how to deal with the disease. Determining the tactics of treatment, the neurologist collects a general history of the patient. Since it is impossible to find the only and true cause of the pathology, it is necessary to improve cerebral circulation by any means. Therapy, both with single foci and with multiple foci, is based on several specific postulates:

• Adherence to the correct regimen and adherence to diet number 10. Every day, the patient is advised to devote enough time to rest. Do not overload yourself with physical work, eat right. The diet should contain organic acids (raw or baked fruits, compotes, juices, fruit drinks, almonds). Patients at risk, or those who are diagnosed with "focal brain changes" after the examination, it is necessary to exclude foods enriched with calcium. It impairs blood flow, which leads to oxygen starvation and single focal changes in brain structures.
• be held drug treatment drugs that positively affect the blood supply to the brain. Such drugs stimulate blood flow, dilate blood vessels, reduce viscosity, and prevent thrombosis.
• The patient is given analgesics to relieve pain syndrome, sedatives, vitamin therapy.
• With hypo- or hypertension - taking medications that normalize blood pressure, which is necessary for the proper functioning of the brain.

If focal lesions of the brain are not treated and the disease is started, severe disorders develop, with which modern medicine can't fight. This is:

• Alzheimer's disease is one of the most common forms of degeneration of nerve cells and structures.
• Pick's syndrome is a rare, progressive disease that affects people over 50 years of age.
• Huntington's disease is a genetic disorder that manifests itself in flight.
• Cardiocerebral syndrome, in which the functions of the brain are impaired due to severe diseases of the cardiac system.
• Arterial hypertension, the exacerbation of which can lead to serious problems with the patient's health.

It is possible to develop an oncological process.

Prevention

The consequences of a severe traumatic brain injury, signs of old age, provoking focal changes in the brain - this is not a reason to despair and give up. You can overcome and prevent the disease by following simple recommendations:

• Walking, running, swimming more often. Play team games, visit a fitness club 2-3 times a week, do any activity that requires physical activity.
• Exclude or limit the use of alcohol, do not get involved in fatty, spicy, salty, smoked foods. If possible, replace sweets with fresh fruits and vegetables. But you don't have to give up your favorite foods either. If there is a desire to eat sausage, it is better to boil it, rather than fry it.
• Stress and anxiety should be avoided. The mental state directly affects not only the brain, but also other organs. It is very difficult to treat diseases associated with depression, and the result is not always positive.
• At the first symptoms, you should consult a doctor. To control the state of health, you need to undergo an examination 1-2 times a year.
• Self-prescribe medication, take medicines, or use prescriptions traditional medicine Absolutely forbidden. It is better to first consult with a specialist and strictly follow all the procedures that he recommends.

Give a prognosis as to how focal changes in the substance of the brain of a dyscirculatory nature will behave in the future and diffuse disorders, even the most qualified doctor will not be able to. The patient's condition largely depends on age, the presence of concomitant diseases, the size of the focus, the degree and dynamics of development. It is important to constantly monitor the patient, take preventive measures to avoid the growth of the affected area.

Focal changes in the white matter of the brain

The human body is not eternal and with age it develops various pathological processes. The most dangerous among them are focal changes in the substance of the brain of a discirculatory nature. They occur as a result of impaired cerebral blood flow. Such a pathological process is manifested by a number of neurological symptoms and is characterized by a progressive course. It will no longer be possible to return the lost nerve cells to life, but it is possible to slow down the course of the disease or even prevent its development.

Causes and signs of pathology

What to do with a focal change in the substance of the brain should tell the doctor, but the patient himself can suspect the presence of pathology. The disease often has a postischemic origin. It is characterized by a violation of blood flow in one of the sections of the hemisphere (hemisphere). It is difficult for some people to understand what it is, therefore, for convenience, the development of changes in the brain substance was divided into 3 stages:

• First stage. At this stage, signs of focal lesions in the substance of the brain do not appear. The patient may feel only slight weakness, dizziness and apathy. Occasionally, sleep is disturbed and headaches bother. Foci of vascular genesis are just emerging and there are small disruptions in the blood flow;
• Second phase. As the pathology develops, the course of the disease worsens. This manifests itself in the form of a migraine, a decrease in mental abilities, ringing in the ears, outbursts of emotions and a disorder in coordination of movements;
• Third stage. If the disease has reached this stage, then focal changes in the white matter of the brain have irreversible consequences. Most of the neurons die and the patient's muscle tone rapidly decreases. Over time, symptoms of dementia (dementia) appear, the sense organs cease to perform their functions, and the person completely loses control over his movements.

Subcortical lesions in the white matter, localized under the cerebral cortex, may not appear at all for a long time. Diagnosis of such failures is mostly accidental.

Changes in the white matter of the frontal lobes are manifested much more actively and mainly in the form of a decrease in mental abilities.

At-risk groups

If there are no signs of the disease, it is advisable to find out what risk groups this disease has. According to statistics, focal lesions often occur in the presence of such pathologies:

• Atherosclerosis;
• High pressure;
• VVD (vegetovascular dystonia);
• Diabetes;
• Pathology of the heart muscle;
• Constant stress;
• Sedentary work;
• Abuse of bad habits;
• Overweight.

Damage to the white matter of the brain of vascular origin may appear as a result of age-related changes. Usually there are small single foci in people after 60 years.

Dystrophic nature of damage

In addition to damage caused by vascular genesis, there are other types of disease, for example, single focal changes in the substance of the brain of a dystrophic nature. This type of pathology occurs due to lack of nutrition. The reasons for this phenomenon are as follows:

• Weakened blood supply;
• Osteochondrosis of the cervical region in the acute stage;
• oncological diseases;
• Head injury.

Damage to the substance of the brain of a dystrophic nature usually manifests itself due to a lack of nutrition of the brain tissues. The patient has the following symptoms:

• Decreased brain activity;
• dementia;
• Headaches;
• Weakening of muscle tissue (paresis);
• Paralysis of certain muscle groups;
• Dizziness.

Diagnostics

In most people, with age, focal changes in the substance appear due to tissue degeneration or due to disruptions in the blood flow. You can see them using magnetic resonance imaging (MRI):

• Changes in the cerebral cortex. Such a focus occurs mainly due to blockage or clamping of the vertebral artery. This is usually associated with congenital anomalies or the development of atherosclerosis. In rare cases, along with the appearance of a focus in the cerebral cortex, a vertebral hernia occurs;
• Multiple focal changes. Their presence usually indicates a pre-stroke condition. In some cases, they can prevent dementia, epilepsy and other pathological processes associated with vascular atrophy. If such changes are detected, a course of therapy should be started urgently to prevent irreversible consequences;
• microfocal changes. Such damage is found in virtually every person after years. You can see them with the use of a contrast agent only if they have a pathological nature of occurrence. Small-focal changes are not particularly evident, but as they develop, they can cause a stroke;
• Changes in the white matter of the frontal and parietal lobes subcortically and periventricularly. This type of damage occurs due to constantly elevated pressure, especially if a person has had a hypertensive crisis. Sometimes small single foci are congenital. The danger arises from the growth of lesions in the white matter of the frontal and parietal lobes subcortically. In such a situation, the symptoms gradually progress.

If a person is at risk, then an MRI of the GM (brain) should be done once a year. Otherwise, it is advisable to do such an examination every 2-3 years for prevention. If MRI shows a high echogenicity of the focus of disculatory genesis, then this may indicate the presence of an oncological disease in the brain.

Methods of dealing with pathology

Gradually affecting human brain tissue, the disease can cause irreversible consequences. To prevent changes in the white matter of the brain of a vascular nature, it will be necessary to stop the emerging symptoms and improve blood flow with the help of medications and physiotherapy. Treatment should be comprehensive, which means you will have to change your lifestyle. To do this, you will have to follow these rules:

• Active lifestyle. The patient should move more and play sports. After eating, it is advisable to go for a walk and do the same before going to bed. Water treatments, skiing and running are good. Treatment with an active lifestyle improves the general condition, and also strengthens the cardiovascular system;
• Properly formulated diet. For successful treatment, you will have to give up alcoholic beverages and reduce the consumption of sweets, conservation, as well as smoked and fried foods. You can replace them with boiled food or steaming. Instead of purchased sweets, you can cook a homemade pie or eat fruit;
• Avoidance of stress. Constant mental stress is one of the causes of many diseases, so it is advisable to relax more and not overwork;
• Healthy sleep. A person should sleep at least 6-8 hours a day. In the presence of pathology, it is desirable to increase the sleep time by 1-2 hours;
• Annual survey. If a change in the white matter of the brain is diagnosed, then the patient should undergo an MRI 2 times a year. It is imperative to follow all the recommendations of the doctor and take the necessary tests on time.

Treatment of focal changes usually consists of lifestyle changes and the elimination of the cause of their development. It is desirable to detect the problem immediately in order to be able to slow it down. For this, a complete examination should be carried out annually.

The regulation of blood supply in the human head is a special mechanism of physiology. The functions of this mechanism are aimed at supporting and normalizing blood circulation in the brain in situations where the systemic blood flow changes for any reason. This compensates for failures in the chemical composition of the environment that surrounds the vessels, as well as blood. If blood supply is disturbed in some part of the brain, then focal changes in the substance of the brain of a dyscirculatory nature may occur. At this time, there may be a loss of brain tissue function, and the severity of the lesion is determined by how much the blood flow has decreased.

There can be many reasons that can lead to failures in the cerebral blood flow system. The general picture of the localization of structural changes inside the brain tissues, their severity; mechanisms of damage that give rise to the development of disorders; the area of ​​blood flow to the damaged vessel, the individual characteristics of the organism - all such deviations in the brain structures are related to the morphological features of this diagnosis. These signs of damage can be determined on an MRI. This will help to highlight the places of circulatory failures, both local and widespread.

Local, or focal, changes in the white matter of the brain are diseases that are dysfunctions not of the whole brain, but only of a certain small part or several parts. A heart attack in the brain would be such a lesion. In addition, a stroke, for example, of a hemorrhagic type, as well as a hemorrhage under the membrane. The nature and course of the disease may also differ:

1. Dystrophic type of disease;
2. Discirculatory type of diagnosis;
3. Postischemic type of condition.

Single focal changes in the substance of the brain of a dyscirculatory nature are diagnoses that are quite closely associated with chronic lesions of the cerebral and spinal blood flow. Such disorders develop and progress slowly, but very hard.

Focal changes in the brain are very difficult to detect at their primary stages of development. Such conditions do not have a good and vivid expression of symptoms. All symptoms manifest themselves in the form of microsymptoms of a diffuse nature. This type of single focal changes in the substance of the brain of a dyscirculatory nature most often appear together with concomitant diseases, for example, such as neuroses, atherosclerosis, vegetovascular dystonia, and arterial hypertension.

In general, if we give a simple definition, then such foci in the white matter in some areas and in certain places of the human brain appear due to vascular genesis, disturbances in the blood supply and blood circulation through the vessels of the brain.

Any type and kind of brain damage, as well as functional disorders of its structure and activity or the work of body systems that are closely related to it, are necessarily reflected in the daily activities of a person, his behavior, functions. Also, the very location of the lesion can very noticeably affect the functioning of the body's organ systems, as well as the proper functioning of the musculoskeletal and musculoskeletal systems.

In addition to pathologies that were caused by vascular genesis, other types of diagnoses may also occur, including single focal changes in the substance of the brain of a dystrophic nature. This kind of pathology can most often occur with insufficient supply of nutrients and oxygen to the brain tissue.

The reasons for this phenomenon:

1. Oncological type of tissue damage;
2. Insufficient blood supply to a certain area of ​​\u200b\u200bthe tissue;
3. Injury to the head and brain tissue;
4. Acute stage of cervical osteochondrosis.

When, due to vascular genesis, small focal changes in the brain occur in a person, the following symptoms are usually observed:

1. Significant decrease in brain activity;
2. Pain in the head;
3. dementia;
4. Frequent dizziness;
5. Paresis of muscle tissue, weakening;
6. Local, partial paralysis of some muscle groups.

In addition, changes in blood circulation around the substance of the brain of a dystrophic nature can also lead to a disorder of the human psyche. In view of vascular degeneration, blood pressure may increase, a stroke may occur, as well as hyperintense brain phenomena. But it can also happen that subcortical lesions may not be symptomatic.

The main signs of the presence of focal disorders

One of the main symptoms is hypertension. After all, if the blood circulation in the brain is disturbed, then it will suffer from a lack of oxygen, and this, in turn, will immediately lead to an acceleration of signals about the supply of blood to the brain, thereby increasing blood pressure. In addition, epileptic seizures can also be observed in a sick person. A variety of mental disorders are also the main symptom of focal brain damage. After all, with pathological phenomena in the subarachnoid spaces, hemorrhages often occur. This can lead to formations in the fundus, darkening and other symptoms that appear in the fundus. Here, darkenings form very quickly, the vessels around the eye burst and retinal rupture can occur. Based on these signs, it is possible to determine exactly where the multiple foci are located.

A possible stroke or micro-stroke is also the main symptom. Focal changes in the brain are usually clearly visible on MRI, which makes it possible to determine the pre-stroke state. This will allow the doctor to immediately prescribe the right treatment. The most obvious signs of damage can be considered single and multiple, small and large involuntary muscle contractions.

And, of course, pain is no exception. Migraines, frequent and severe headaches clearly indicate disorders of a multifocal nature.

Treatment

Individual changes in the white matter, which are clearly defined on MRI, may mean that the patient has abnormalities in the blood circulation of the brain of vascular origin. Based on these data, the doctor will prescribe an examination that will more clearly show the causes of this situation, and will allow you to prescribe the correct treatment.

To select the treatment of focal changes in the substance of the brain of a dyscirculatory nature, the doctor first prescribes therapy for the disease that led to this alignment. Drugs are prescribed that improve blood circulation between brain structures, oxygen metabolism, reduce blood viscosity, have a sedative and analgesic effect, as well as complexes of vitamins and necessary elements.

In addition, to restore the functions of the white matter of the brain, if possible, the patient is prescribed a strict diet, bed rest and rest. This will help to avoid further changes in the substance of the brain. The patient's regimen should be normalized, it is important to exclude any physical activity, as well as completely review his diet. You should unquestioningly obey the doctor's orders.

Prevention

Prevention of multiple focal changes in the substance of the brain includes:

1. Leading an active lifestyle. After all, movement stimulates the improvement of blood circulation throughout the human body and in the brain, in particular, and thereby reduces the risk of lesions in the brain substance.
2. Proper and rational nutrition.
3. Avoid stress and other nervous situations. After all, constant nervous tension can be the cause of more than one disease. No need to overwork often, you should rest and relax more.
4. Healthy and sound sleep is always a guarantee of health. You need to spend at least 7-8 hours of sleep per day. If there is insomnia or any other sleep pathology, then sleep time should be increased to 10 hours a day.
5. It is necessary to conduct an examination in the hospital every year to identify hidden pathologies and diseases. If symptoms are found that may indicate changes in the medulla, then an MRI is required 2 times a year, as well as all the necessary tests.

Everyone knows that it is always easier to prevent a problem in advance than to look for the right and correct solution later. Also with health. It is easier to carry out the necessary prevention than to treat the disease later.
