Dyscirculatory changes in the brain substance. Focal changes in the white matter of the brain. Stages and symptoms of disease development

The human body is not eternal and with age various pathological processes develop in it. The most dangerous among them are focal changes in the brain substance of a discirculatory nature. They arise due to disruption of cerebral blood flow. This pathological process manifests itself in a number of ways and is characterized by a progressive course. It is no longer possible to bring lost nerve cells back to life, but you can slow down the course of the disease or completely prevent its development.

The doctor should tell you what to do if there is a focal change in the substance of the brain, but the patient himself can suspect the presence of pathology. The disease often has a post-ischemic origin. It is characterized by a violation of blood flow in one of the areas of the hemisphere (hemisphere). It is difficult for some people to understand what this is, so for convenience, the development of changes in brain matter has been divided into 3 stages:

• First stage. At this stage, signs of focal lesions in the brain matter do not appear. The patient may only feel slight weakness, dizziness and apathy. Occasionally, sleep is disturbed and headaches occur. Foci of vascular origin are just emerging and there are minor disruptions in blood flow;
• Second phase. As the pathology develops, the course of the disease worsens. This manifests itself in the form of migraines, decreased mental abilities, ringing in the ears, outbursts of emotions and loss of coordination of movements;
• Third stage. If the disease has reached this stage, then focal changes have irreversible consequences. Most neurons die and the patient’s tone rapidly decreases muscle tissue. Over time, symptoms of dementia (dementia) appear, the senses 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 long time. Such failures are diagnosed mainly by chance.

Changes in the white matter of the frontal lobes manifest themselves noticeably 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 are for this disease. According to statistics, focal lesions more often occur in the presence of such pathologies:

• Atherosclerosis;
• High pressure;
• VSD (vegetative-vascular dystonia);
• Diabetes;
• Pathologies 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. Small single lesions are usually observed in people over 60 years of age.

Dystrophic nature of the damage

In addition to damage caused by vascular origin, there are other types of disease, for example, single focal changes in the brain substance 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 cervical spine in the acute stage;
• Oncological diseases;
• Head injuries.

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

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

Diagnostics

Most people with age develop focal changes in the substance that arise due to tissue degeneration or as a result of disruptions in blood flow. You can see them using magnetic resonance imaging (MRI):

• Changes in the cerebral cortex. Such a lesion occurs mainly due to blockage or compression vertebral artery. This is usually associated with congenital anomalies or the development of atherosclerosis. In rare cases, along with the appearance of a lesion 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 immediately to prevent irreversible consequences;
• Microfocal changes. Such damage is found in virtually every person after 50-55 years. See them in use contrast agent is possible only if they have a pathological nature of occurrence. Fine-focal changes are not particularly noticeable, 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 constant high blood pressure, especially if the person had a hypertensive crisis. Sometimes small single lesions are congenital. The danger arises from the proliferation of lesions in the white matter of the frontal and parietal lobes subcortically. In such a situation, symptoms gradually progress.

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

Methods of combating pathology

Gradually affecting the human brain tissue, the disease can cause irreversible consequences. To prevent vascular changes in the white matter of the brain, it will be necessary to stop the symptoms that arise and improve blood flow with the help of medications and physical therapy. Treatment must 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 it doesn’t hurt to do the same before bed. Good influence water treatments, skiing and running. Active lifestyle treatment 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 your consumption of sweets, canned food, as well as smoked and fried foods. You can replace them with boiled or steamed food. Instead of store-bought sweets, you can make homemade pie or eat fruit;
• Avoiding 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 advisable to increase sleep time by 1-2 hours;
• Annual examination. If a change in the white matter of the brain is diagnosed, the patient should undergo an MRI twice a year. It is imperative to follow all the doctor’s recommendations and take the necessary tests on time.

Treatment of focal changes usually involves changing lifestyle and eliminating the cause of their development. It is advisable to detect the problem immediately in order to be able to slow down its progression. To do this, you should undergo a full examination annually.

The brain is a key part of the human nervous system. This is a complex and vulnerable organ, any pathology of which can lead to irreparable health consequences. This is often caused by a focal change in the brain substance of a dystrophic nature - a dangerous and common phenomenon.

At-risk groups

Typically, focal changes in the white matter of the brain of a dystrophic nature most often occur in old age. Most lesions appear during life and as a result of hypoxia and ischemia. People who lead a sedentary and unhealthy lifestyle are also susceptible to the disease. Plays its role and genetic predisposition. The risk group includes people suffering from high or low blood pressure, diabetes, rheumatism, obesity and atherosclerosis. In addition, emotional individuals prone to stress are at risk of developing pathology.

The white matter of the brain coordinates all human activity. It is what connects different parts of the nervous system. White matter is necessary for the two hemispheres to work together.

Causes

Focal changes in the brain substance of a dystrophic nature occur in a number of diseases of different origins:

• Changes in vascular origin: atherosclerosis, migraine, hypertension, etc.
• Inflammatory diseases. Multiple sclerosis, Behçet's disease, Sjögren's disease, inflammatory diseases intestines (Crohn's disease).
• Infectious diseases. HIV, syphilis, borreliosis.
• Intoxication and metabolic disorders, poisoning carbon monoxide, B12 deficiency.
• Traumatic processes associated with radiation therapy.
• Congenital diseases caused by metabolic disorders.

The occurrence of pathology is caused by impaired blood supply in any part of the brain. It is fraught with loss of function of brain tissue. The more blood flow has decreased, the more noticeable the consequences. An example is damage to the spinal or cerebral blood flow. Such disorders progress slowly, but entail severe consequences.

Signs

The signs of focal changes in the brain substance of a dystrophic nature are also different. With focal changes, not the entire brain suffers, but only its individual parts. Tissue degeneration occurs in case of insufficient intake nutrients, necessary for the normal functioning of the body's nervous systems. It's about about proteins - building material human body. Proteins break down into amino acids, which, in turn, stimulate the nervous system. It also requires fats and carbohydrates - the main sources of energy needed by every living creature.

Of the vitamins, the brain needs B1 (activates its work), B3 (provides energy at the intracellular level), B6 ​​(it is difficult to imagine metabolic processes without it, in addition, it is also a kind of antidepressant), B12 (promotes memory preservation and helps to stay alert) . All these vitamins can be obtained in sufficient quantities by creating the right diet.

initial stage

On initial stage lesions human brain signs of the disease practically do not appear. The patient can only complain about lack of strength and apathy. At this stage, sources of problems in blood vessels are just emerging and are difficult to distinguish.

Second stage

A focal change in the substance of the brain of a dystrophic nature at the second stage is manifested by more serious symptoms: a person’s headache, the ability to perceive and process information decreases, ringing in the ears appears, coordination of movements is impaired, the character becomes more irritable and aggressive.

Third stage

When the disease reaches the third stage of development, the brain pathology is considered irreversible. Gradually, the patient develops symptoms of dementia, paralysis and paresis rapidly develop, and the senses work with less and less efficiency.

Pathologies

Focal changes Dystrophic brain substances most often take the form of pathologies such as:

• Cyst - cavity small size which is filled with liquid. It often interferes with the normal functioning of neighboring areas of the brain, as it compresses blood vessels. Cysts are divided into intracerebral (cerebral) and arachnoid. The latter appears in the meninges. Its occurrence is facilitated by the accumulation of cerebrospinal fluid and inflammatory processes. Cerebral occurs in place of dead brain tissue.
• Necrotic state of tissue - appears when the supply of important nutrients to areas of the brain for any reason deteriorates. Dead cells form so-called dead zones and are not regenerated.
• Hematomas and brain scars occur after severe trauma or concussion. Foci of this type lead to structural damage.

Diagnostics

Full picture focal changes in the brain substance of a dystrophic nature are determined using an MRI study. This procedure allows you to see even small areas of transformation in the white matter. And they, in turn, lead to cancer and stroke.

Focal dystrophic lesions are different sizes, differ in location. Based on this, the examination may show some types of disorders.

In the cerebral hemisphere, blockage of vital arteries is usually diagnosed due to abnormal development of the embryo or acquired atherosclerotic plaques. A herniated cervical spine is also detected.

Changes in the white matter of the brain indicate hypertension, congenital anomalies development. In other cases, multiple areas of brain pathology may indicate a pre-stroke condition, senile dementia, epilepsy.

Sometimes doctors perform tests on a patient to detect the presence of cognitive impairment. That is, cognitive dysfunction. Such as orientation in space and time, understanding of external processes, the ability to remember information, drawing, writing, reading, etc.

Focal changes in the brain substance of a dystrophic nature can develop in three ways:

1. In the first case, the disease is remitting in nature. Symptoms increase gradually, the condition worsens, and brain productivity decreases. But from time to time, remissions occur - temporary improvements in health, after which the patient again becomes worse.
2. Progressive focal changes in the brain substance of a dyscirculatory dystrophic nature develop very quickly. Each stage of the disease takes no more than two years, which is considered a short period for organic brain lesions.
3. Typically, the deterioration of a person suffering from focal changes lasts for many years, eventually leading to dementia.

It should be remembered that single focal changes in the brain substance of a dystrophic nature often appear in young people, and single damage to the white matter in an elderly person is considered normal. Structural disorders of the cerebral arteries of the atherosclerotic type appear in 50% of patients over 50 years of age. For the most part, hypertensive patients suffer from this. Therefore, you need to show the MRI result to a neurologist so that he can determine the severity of the disorders in the brain by comparing the MRI result and the clinical picture of the disease.

Diet

In the early stages of this disease, it is enough to reconsider your lifestyle and diet, choosing a more gentle regimen and diet. In the diet, it is advised to reduce the consumption of animal fats, and it is better to completely replace them with vegetable ones. You should eat fish and seafood instead fatty meat, reduce the amount of salt in your diet. Will bring great benefit fresh vegetables and fruits.

Treatment

Focal anomalies great amount, therefore, each has its own cause of occurrence. Treatment of brain pathologies is based on the destruction of those factors that led to the appearance of lesions in brain tissue. In addition to eliminating the underlying disease, the doctor may also prescribe vitamins and medications to help combat the deterioration of cerebral blood flow.

The treatment process depends directly on what somatic problems in the body led to the occurrence of lesions in the brain. For infections, for example, antibiotics are taken; for injuries, diuretics, decongestants, anticonvulsants. If the damage to the brain tissue was caused by a circulatory disorder, then nootropics and coagulants are prescribed.

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

Cerebrovascular accidents are:

• Diffuse;
• Focal.

Focal changes in the brain substance of a dystrophic nature are disorders that do not affect the entire brain tissue, but only individual areas, foci. The functions of brain tissue 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 various nature and degree of prescription, areas of necrosis, small cysts, gliomesodermal scars.

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

• Ischemia, which is characterized by a decrease in blood circulation to the brain;
• Cervical osteochondrosis in the acute stage, as well as with changes in patency great vessels, which supply blood to the hemispheres, brain stem, cerebellum;
• Head injury;
• The tumor as it grows.

Symptoms of such changes in the human body include severe and prolonged headaches, insomnia, constant dizziness without neurological symptoms. Memory and intellectual abilities of a person, coordination of movements deteriorate, and performance decreases. The emotional-volitional sphere suffers, sensitivity decreases. Paresis and paralysis appear.

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

Treatment is the normalization of work and rest, proper diet and the prescription of a number of drugs that improve cerebral circulation, as well as analgesics and sedatives. If focal changes are recognized in time, they further development can be stopped or significantly slowed down. What cannot be done with the development of senile dementia, which is caused by atrophic changes in the brain.

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

Otherwise, atrophic changes in the brain are also called dementia - a synonym for the word dementia, a disorder of thinking processes. Alzheimer's, Parkinson's, Pick's diseases, Huntington's chorea and some more rare diseases belong to atrophic dementia.

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 tissue are irreversible, and it is impossible to stop the progressive course. You can only alleviate certain symptoms. For example, when strong 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 a hospital setting.

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

The presence of small perineural cysts is observed in approximately 7% of people on our planet. Interestingly, they are more often observed in women. Brief description

Arnold-Chiari malformation type 1 is detected in the form of descent of structures located within the posterior cranial fossa into the cavity of the spinal canal.

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

Carrying out MRI for focal brain lesions

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

Signs of focal lesions

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

• Hypertension - a lack of oxygen supply to the brain caused by vascular dystrophy leads to the fact that the brain accelerates and increases blood circulation.

Diagnosing 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 normal blood supply stops, causes provoking changes in soft tissues. Resonance tomography helps to identify the causes of violations and carry out differential analysis diseases.

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 the disorders.

• In the cerebral hemispheres - indicates the following possible reasons: blockage of blood flow to the right vertebral artery due to a congenital anomaly or atherosclerotic plaque. The condition may be accompanied by a herniated cervical spine.

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

Each part of the brain performs specific functions - regulates speech, thinking, balance, attention, and controls the functioning 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 all this is difficult organized system directly depends on the blood supply. Even minor damage to blood vessels leads to serious consequences. One of the manifestations of this pathology is considered to be focal changes in the brain.

What pathologies exist

Due to a 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 lose part or all of their natural functions. There are two types of dystrophic disorders:

1. Diffuse, covering the entire brain tissue evenly, without the occurrence of pathological areas. They appear due to impaired blood circulation, brain injuries, concussions, and inflammation caused by infections. Symptoms of diffuse pathologies are often decreased ability to work, unbearable constant pain in the head, apathy, lethargy, insomnia.
2. Focal changes in the brain substance of a discirculatory nature, covering a separate area where blood circulation is impaired. The lesions can be single or numerous, randomly scattered throughout the brain tissue. Basically, this is a sluggish ongoing chronic disease that develops over years.

Common focal pathologies include:

• A cyst is a small cavity filled with fluid. Often it does not cause discomfort or pain in patients, 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 forming dead zones do not perform their functions and are not restored in the future.
• Brain scar and hematoma that occurs after severe injury or concussion. These focal changes in the brain result in minor structural damage.

Stages of development of dyscirculatory changes

There are three stages of this pathology:

1. Initially, discirculatory changes are characterized by a slight disturbance in the movement of blood in certain brain areas. Because of this, the patient quickly gets tired and often experiences bouts of dizziness and headaches.
2. When the disease develops and moves into the second stage, the damage worsens. Memory deteriorates, intellectual abilities decrease. The person becomes extremely irritable and emotional. Coordination of movements worsens, and tinnitus appears.
3. At the third stage, a significant part of the neurons die. In this case, the muscles noticeably suffer, obvious signs of dementia appear, and the organs of touch and senses may fail.

From where the focal ones are localized diffuse changes vascular nature in the brain and spinal cord, depends on how the functionality of the organs that are sensitive to such disorders changes.

Symptoms of focal lesions

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

• High arterial pressure, provoked by a lack of oxygen due to the degenerative state of the cerebral vessels.
• Epileptic seizures, during which a person should not put metal objects in his mouth, pour water on him, hit him on the cheeks, etc.
• Mental disorders, memory impairment, distorted perception of reality, atypical behavior.
• Stroke or pre-stroke condition, which can be detected on CT or MRI.
• Increasing throbbing headache in the back of the head, eye sockets, superciliary areas, radiating across the surface of the entire skull.
• Out of control muscle contractions, tremor of the limbs, chin, eyes, neck.
• Ear noise, ringing, congestion leading to nervousness.
• Regular attacks of dizziness leading to nausea and vomiting.
• Photophobia, decreased hearing acuity, blurred vision, double vision, noticeable blurred vision.
• Constant fatigue, apathy.
• Slurred speech.
• Sleep disturbances.
• Muscle paresis, pathological reflex reaction limbs.

Many people ask what diseases are caused 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 accumulations in the walls of blood vessels.
• Osteochondrosis of the neck.
• Oxygen starvation.
• Neoplasms.
• Injuries, open and closed head injuries (age is not important here).

Who is at risk

Any disease has its own risk groups. People belonging to such groups should closely 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.
• Obesity.
• Sensitive, emotional people living in constant stress.
• Leading a sedentary life.
• Elderly people, regardless of gender(starting the rally).

They also provoke the development of vascular pathologies:

Diagnostics

Focal brain lesions are often asymptomatic. Even if there are minor symptoms, patients rarely go to doctors. It is difficult to identify pathology. This can be done by undergoing an MRI examination. It allows us to examine even small degenerative lesions that can lead to stroke or cancer.

MRI may indicate the following disorders:

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

Numerous small lesions threaten life and cause many serious illnesses. They are mainly 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. When deciding on treatment tactics, the neurologist collects general anamnesis sick. Since the only and the real reason it is impossible to find pathologies; it is necessary to improve cerebral circulation by any means. Therapy, both for single lesions and for multiple ones, is based on several specific postulates:

• Sticking correct mode and following diet No. 10. The patient is advised to devote sufficient time to rest every day. Don't overload yourself physical work, Healthy food. The diet should contain organic acids (raw or baked fruits, compotes, juices, fruit drinks, almonds). Patients at risk or those who, after examination, have been diagnosed with focal changes in the brain, should exclude foods fortified with calcium. It impairs blood flow, which leads to oxygen starvation and isolated focal changes in brain structures.
• Conducted drug treatment drugs that have a positive effect on the blood supply to the brain. Such medications stimulate blood flow, dilate blood vessels, reduce viscosity, and prevent blood clots.
• The patient is prescribed analgesics that relieve pain syndrome, sedatives, vitamin therapy.
• For hypo- or hypertension - take medications that normalize blood pressure necessary for proper operation brain

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

• Alzheimer's disease is one of the most common forms of degeneration nerve cells and structures.
• Pick 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 early childhood.
• Cardiocerebral syndrome, in which brain function is impaired due to severe diseases of the cardiac system.
• Arterial hypertension, the exacerbation of which may lead to serious problems with the patient's health.

The development of an oncological process is possible.

Prevention

The consequences of 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:

• Walk, run, and swim more often. Play team games, visit a fitness club 2-3 times a week, do any activity that requires physical activity.
• Eliminate or limit the consumption of alcohol, do not get carried away with fatty, spicy, salty, smoked foods. If possible, replace sweets with fresh fruits and vegetables. But you shouldn’t give up your favorite dishes either. If you want 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. Treating illnesses associated with depression is very difficult, and the results are not always positive.
• At the first symptoms you should consult a doctor. To monitor your health, you need to undergo examinations 1-2 times a year.
• Self-prescribe treatment, take medications 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.

Even the most qualified doctor will not be able to give a forecast as to how focal changes in the brain substance of a discirculatory nature and diffuse disorders will behave in the future. The patient’s condition largely depends on age, the presence of concomitant diseases, the size of the localization of the lesion, the degree and dynamics of development. It is important to constantly monitor the patient and preventive actions to prevent the affected area from growing.

Dystrophic changes in the brain substance treatment

Please explain the conclusion of MRI of the brain

Hello! Today my mother underwent a study - an MRI of the brain, after which the clinic gave the conclusion: On a series of MRI tomograms weighted by T1 and T2 in three projections, sub- and supratentorial structures were visualized. The lateral and third ventricles of the brain are slightly dilated. The fourth ventricle is unchanged, the basal cisterns are of normal caliber. The chiasmal area is without features; the pituitary tissue has a normal signal. Subarachnoid convexital spaces and grooves are slightly expanded in the area of ​​the parietal lobes and Sylvian fissures with moderately pronounced atrophic changes brain substances. The midline structures are not displaced. The cerebellar amygdala is located usually. In the white matter of the parietal and temporal lobes, multiple hydrophilic foci of different sizes, small areas of gliosis, and enlarged Virchow-Robin spaces are detected. CONCLUSION: MR picture is moderately mixed replacement hydrocephalus. Multiple focal-dystrophic substances of the brain. My mother is 41 years old. IN Lately she began to complain about: - she rocks as if on the waves; - Nausea; - Dizziness; - Periodic severe headaches (in occipital region); - Pawns ears; - Memory impairment; - Can’t concentrate on anything; - Sleep disturbance; - Weakness; - Nervousness. Please explain the situation, diagnosis, treatment. Thank you in advance! P.S. Before the study, she completed a course of treatment prescribed by a neurologist: 1) Actovegin 2.0 IV in saline solution; 2) Mexidol 2.0 IM; 3) Platyphylline 1.0 IM. During the course of treatment, the health situation worsened. At the end of treatment positive results did not have.

Hello! Focal changes in the substance of the brain of a dystrophic nature - this is literally - as a result of a local (local) disruption of the blood supply (age-related, toxic or other nature) there are atrophied (dead) areas of brain tissue. This is how encephalopathy manifests itself. Treatment usually includes vasoactive drugs, so-called “cerebral circulation optimizers”: Cavinton, Trental, cinnarizine, stugeron, etc. vascular insufficiency In the vertebrobasilar system, preference is given to stugeron and sibelium. betserku. If the patient has a combination of atherosclerotic lesions of the blood vessels of the brain and extremities, the appointment of sermion is indicated. Nootropics (gliatilin, cortexin, ceraxon). Decongestants (diacarb, veroshpiron).

Focal changes in the brain substance 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 maintain vital functions.

According to various sources similar disease 50 to 70% of elderly people (over 60 years old) suffer.

Symptoms of dystrophy of the brain substance

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

• First stage. In the first couple of days, a person feels a little tired, lethargic, dizzy and sleeps poorly. This occurs due to decreased blood circulation in the brain. The degree of significance increases with the development of vascular diseases: cholesterol deposition, hypotension, etc.
• Second stage. At the second stage, a so-called “disease focus” appears in the brain; damage to the brain substance deepens due to poor blood circulation. The cells do not receive enough nutrition and gradually die. 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 last stage, the focus of the disease moves even deeper, the affected vessels bring too little blood to the brain. The patient exhibits signs of dementia, lack of coordination of movements (not always), dysfunction of the sensory organs is possible: loss of vision, hearing, shaking hands, etc.

The exact changes in the brain substance can be determined using MRI.

Without treatment, diseases such as:

1. Alzheimer's disease. The most common form of nervous system degeneration.
2. Pick's disease. A rare progressive disease of the nervous system that manifests itself in the first place.
3. Huntington's disease. Genetic disease of the nervous system. developing rally.
4. Arterial hypertension.
5. Cardiocerebral syndrome (impairment of basic brain functions due to cardiac pathology).

Reasons for changes

As already mentioned, the main cause of the disease is vascular damage. arising inevitably with age. But for some, these lesions are minimal: small cholesterol deposits, for example, but for others they develop into pathology. Thus, diseases of a dystrophic nature lead to changes in the substance of the brain:

1. Ischemia. This disease is mainly characterized by impaired blood circulation in 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 in it should be extremely careful. If a person has similar diseases, then he is in the primary risk group, if only predisposition, then in the secondary:

• Suffering from diseases of the cardiovascular system: hypotension, hypertension, hypertension, dystonia.
• Patients with diathesis, diabetes mellitus or stomach ulcers.
• Having overweight or poor eating habits.
• Those who are in a state of chronic depression (stress) or leading sedentary image life.
• People are older, regardless of gender.
• Suffering from rheumatism.

For people in the main risk group, first of all, it is necessary to cure the underlying disease, followed by recovery of the brain. Patients with hypertension and all its forms of manifestation should be especially careful.

How to overcome it?

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

Firstly, lead an active lifestyle. Walk or jog for at least two hours a day. Walk on fresh air: in the forest, in the park, driving out of town, etc. Play outdoor games that suit your physical abilities: basketball, pioneer ball, volleyball, tennis or table tennis, etc. The more movement, the more active the heart works and the blood 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 a strict diet! If you want meat, then you don’t need to fry it or drip the 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 junk food and products can be replaced with their equivalents.

Thirdly, avoid stressful situations and overwork. A person's mental state directly affects his health. Don't overwork yourself, rest if you're tired, sleep at least 8 hours a day. Don't overexert yourself with physical activity.

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

It is best not to try to help your body with “home methods”: taking medications on your own, injecting yourself, etc. Follow the doctor's instructions and undergo the procedures he prescribes. 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 medications if he is not sure of the accuracy of the diagnosis.

Focal changes in the brain substance of a discirculatory nature

Without exaggeration, the brain can be called a control system for the entire human body, because different lobes 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 a huge amount of information; At the same time, hundreds of thousands of processes take place in it to ensure the vital functions of the body. 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 portion medulla may lead to irreversible consequences #8212; massive death of neurons and, as a result, severe diseases of the nervous system and dementia.

Causes and symptoms of focal changes of a discirculatory nature

The most common manifestations of impaired blood supply to the brain are focal changes in the brain substance of a discirculatory nature, which are characterized by impaired blood circulation in certain areas of the brain substance, and not in the entire organ. As a rule, these changes #8212; This chronic process, developing over quite a long time, and in the first 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 discirculatory nature:

1. At the first stage, in certain areas of the brain, due to vascular diseases, minor violation blood circulation, as a result of which a person feels tired, lethargic, apathetic; The patient experiences sleep disturbances, periodic dizziness and headaches.
2. The second stage is characterized by deepening of vascular damage in the area of ​​the brain, which is the focus of the disease. Symptoms such as memory loss and intellectual abilities, violation emotional sphere, severe headaches, tinnitus, coordination disorders.
3. The third stage of focal changes in the brain substance of a discirculatory nature, when a significant part of the cells in the focus of the disease due to circulatory disorders has died, is characterized by irreversible changes in the functioning of the brain. As a rule, in patients at this stage of the disease, muscle tone is significantly reduced, there is practically no coordination of movement, signs of dementia (dementia) appear, and sensory organs may also fail.

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

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

• suffering from hypertension, vegetative-vascular dystonia and other diseases of the cardiovascular system;
• patients with diabetes mellitus;
• suffering from atherosclerosis;
• having bad habits and being overweight;
• leading a sedentary lifestyle;
• those in a state of chronic stress;
• elderly people over 50 years of age.

Focal changes of a dystrophic nature

In addition to changes of a discirculatory nature, a disease that has similar symptoms, are single focal changes in the brain substance of a dystrophic nature due to a lack of nutrients. This disease affects people who have suffered head trauma, ischemia, cervical osteochondrosis in the acute stage and patients diagnosed with a benign or malignant brain tumor. Due to the fact that the vessels supplying a certain area of ​​the brain cannot fully perform their functions, the tissues in this area do not receive all the necessary nutrients. The result of such #171;fasting#187; nerve tissue #8212; headaches, dizziness, decreased 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, every person can significantly reduce the risk of developing focal changes in the brain substance. To do this, it is enough to refuse bad habits, live healthy and active image life, avoid overwork and stress, consume healthy and healthy food and undergo a preventive medical examination 1-2 times a year.

There are several important organs, without whose work we cannot live. One of them is the brain. With diffuse or focal lesions of the brain, the coordinated work of the whole organism suffers.

Local (focal) damage is local damage to the structures of the brain matter, manifested by a disorder of certain functions. In other words, a pathological focus (formation) appears in the gray or white matter, which is accompanied by neurological symptoms. For greater clarity, it is worth listing all the reasons by frequency of occurrence.

Vascular disorders

This is one of the largest groups, since diseases of the cardiovascular system, according to statistics, occupy first place in the world. This may include (ONMK). It is strokes that play a leading role in the appearance of focal changes in the brain of vascular origin.

Under the influence of hemorrhage or ischemia, a pathological focus is formed in the gray matter, leading to the occurrence of neurological symptoms. Clinical picture will directly depend on the extent of the lesion, its location, and the factor that caused the circulatory disorder.

Neoplasms

An equally important group of reasons organic damage brain Ranks second in frequency of occurrence. All neoplasms can be divided into benign or malignant.

Sometimes benign tumors may not manifest themselves in any way, but as they grow they squeeze neighboring nerve structures, increase intracranial pressure, making themselves felt by various neurological disorders. It is typical that in 50% of cases they are completely cured surgically.

Cancerous focal changes in the brain substance can be single or multiple, which significantly worsens the prognosis. The tumor can also be primary or metastatic (brought from another affected organ). Treatment of such focal lesions is extremely difficult and, in most cases, unsuccessful.

Brain injuries

For areas of damage to appear in the gray or white matter, the traumatic factor must be quite strong. This group includes severe head contusions, compression, and penetrating wounds. After such injuries, foci of demyelination, ischemia, necrosis, and hemorrhage appear. Neurological symptoms depend on the location of the damaged structure.

Degenerative changes

Appear in old age as a result of atherosclerosis, metabolic disorders, oxygen starvation of nervous tissue, dehydration, organic diseases( , Pick, Parkinson, ). Such changes are associated with physiological age-related processes occurring in all organs.

Infections

Intoxication

In the practice of neurologists, alcohol, narcotic, medicinal, chemical (metal salts) focal changes in the brain substance under the influence of relevant factors are often encountered. The consequence of such poisonings is multiple areas of damage in the nervous tissue.

Perinatal brain lesions in children

This is a large area of ​​focal brain damage to the fetus and newborn child, which is treated by pediatric neurologists.

Types of focal changes in the brain substance

Focal formations include:

Conventionally, all clinical symptoms can be divided: general, focal neurological, and mental. General symptoms include weakness, drowsiness, increased body temperature, chills, decreased appetite, headaches, and dizziness. Experienced doctor a neurologist will be able to determine with 90% accuracy the site of damage in the brain based on complaints and clinical symptoms patient.

If the focus is located in the cortex of the frontal lobe, then speech and its perception suffer, the tone of some muscles increases, a disorder in the movement of the eyes, head, and limbs occurs, and balance is lost when walking.

When the parietal lobe is damaged, the ability to read, write, count is impaired, and tactile sensitivity changes or is lost. The patient cannot correctly determine the position of his limbs in space.

If there is hearing loss, deafness, auditory hallucinations, memory loss, epileptic seizures, then it can be assumed that the pathological focus is located in the temporal lobe.

Various visual impairments (changes in color and light perception, visual illusion, total blindness) speak in favor of damage to the occipital lobe.

What is it: signs, treatment and prognosis.

What is it: causes, manifestations, treatment, prognosis.

Lesions in the cerebellum affect balance and gait. In fact, in practice there are much more focal neurological symptoms: paresis, paralysis, impaired sensitivity of the limbs, fainting, tremors. Even with single focal changes in the substance of the brain, breathing problems, convulsions, and coma can occur.

Mental symptoms accompany neurological symptoms, but sometimes they occur on their own. Mental disorders may include foolishness, depression, irritability, sleep disturbances, anxiety disorder, restlessness, panic attacks or aggression.

Diagnosis of focal brain lesions

Modern medical capabilities make it possible to accurately diagnose focal brain lesions, their number, location, and size. The most informative examinations are MRI and CT (sometimes with contrast). The diagnosis is also aided by existing neurological symptoms.

Treatment of focal formations

Therapy will directly depend on the cause of the appearance of lesions in the brain. For infection, antibiotics are used; for injury, diuretics, decongestants, and anticonvulsants are used. If the disease is caused by circulatory disorders, then vascular medications, nootropics, and anticoagulants are used for treatment. Therapy of malignant tumors involves irradiation, administration of cytostatics, hormones, and surgery.

On a note! Treatment focal formations is handled by a neurosurgeon together with a neurologist and a psychiatrist.

Forecast

It is difficult to say what the prognosis and consequences will be if lesions are identified in the brain. This issue is decided on an individual basis and depends on many factors.
