Problems of circulatory disorders of the brain, all about the causes and treatment. Poor blood circulation in the brain, symptoms of pathology The most negative effect on cerebral blood flow

Obesityfraught with various cardiovascular disorders, among which are especially serious are cerebral circulation disorders, or cerebral strokes.

According to statistical data, the risk of ischemic stroke in overweight (BMI 25-30 kg / cm 2) increases by 22% in comparison with persons with normal body weight. And with a BMI over 30, which corresponds to at least I degree of obesity, the risk increases by 64%, and progressively increases as the degree of obesity increases. With regard to hemorrhagic stroke, which is much more severe than ischemic stroke, the picture is even more depressing. True, these are data from American studies. In the United States, a significant percentage of the Negroid race, which is more prone to obesity and cardiovascular disease than Europeans. But things are not much better in Russia.

Three factors are to blame for the pathogenesis of obesity strokes:

  • Increased blood pressure
  • Pathological changes in the vascular wall
  • Changes in the substance of the brain.

Hypertonic disease - a frequent companion of obesity. And there is a definite relationship between blood pressure and obesity. The bottom line is that the accumulation of adipose tissue and the germination of blood vessels in it (vascularization) are accompanied by an increase in the BCC (circulating blood volume). In addition to BCC, other mechanisms are involved in the formation of hypertension: renal, tissue. As a result, the blood circulating through the cerebral arteries strongly presses on their walls.

The walls themselves are also undergoing negative changes. And the main, but not the only, culprit here is atherosclerosis. Atherosclerotic plaques are formed due to hypercholesterolemia - an increased content of cholesterol in the blood in the form of low-density lipoproteins. Atherosclerotic blockage (occlusion) of the vascular lumen leads to ischemia - a decrease in blood flow, and with it oxygen, into the brain tissue.

Atherosclerotic occlusion is aggravated by thrombotic - in the area of \u200b\u200batherosclerotic plaques, blood flow slows down, which creates the preconditions for thrombosis.Due to high pressure and atherosclerosis, the strength and elasticity of the vascular wall of the cerebral arteries decreases, ulcerations, microaneurysms (small areas of vascular walls and thinning) form on its surface ... The permeability of the walls of the arteries for plasma and blood cells also increases. All this creates conditions for hemorrhage - rupture of a blood vessel and hemorrhage in the brain. In addition, obesity negatively affects the brain. Determined that aging of the brain with obesity occurs about 16 years earlier. The aging process is accompanied by a decrease in the mass and volume of brain tissue, and a decrease in its resistance to hypoxia (oxygen deficiency) under conditions of ischemia.

The main symptoms of violations cerebral circulation are divided into cerebral, focal and mixed.

Among the general cerebral symptoms: headache, nausea, vomiting, general weakness, disturbances of consciousness (stunning, coma), convulsions. Focal symptoms are caused by loss of innervation of certain anatomical areas with brain damage. Focal symptoms: paralysis and paresis (partial paralysis) of the extremities, anisocoria (unequal pupil size), facial asymmetry, speech disorders.

Depending on the mechanism of development, strokes are divided into ischemic and hemorrhagic.

Hemorrhagic strokes are more difficult. As a rule, they begin abruptly, with loss of consciousness and the development of coma against the background of a strong jump in blood pressure. The prognosis for recovery and for life is always serious here, often unfavorable.

Ischemic strokes focal symptomatology is more characteristic. The most favorable variant of ischemia is a transient violation of cerebral circulation, when blood flow through the vessels is restored, and the symptoms regress during the first 24 hours after the onset of the disease.

Stroke treatment

Complex stroke treatment is urgent. Moreover, the selection of drugs for ischemic and hemorrhagic stroke is fundamentally different. Therefore, high-quality diagnosis and treatment requires the experience of a neurologist and the availability of the necessary diagnostic equipment for CT and MRI.

Weight loss with the development of a stroke, it is unlikely that it should be included in the list of therapeutic measures. Rather, it is preventive in nature.

The polyethiology and polysystemic nature of most diseases of the brain and spinal cord necessitate a comprehensive study of cerebral functions, therefore, along with the study of energy metabolism, it is necessary to simultaneously study glucose utilization, local and global cerebral blood flow, as well as the level of cerebral oxygen metabolism. PET (positron emission tomography) meets these requirements. The PET method has shown that the functional activity of a region of the brain in animals and humans correlates with a regional increase in cerebral blood flow and glucose or oxygen metabolism, and a decrease in brain activity is reflected in their suppression (FECamargo et al., 1991; DEKuhl et al., 1982; DEKuhl et al., 1984; EJMetter, WRHanson, 1986; MERaichle et al., 1984; D. Rougemont et al., 1983; JLTyler et al., 1988; JRWagner, 1985; K. Wienhard et al., 1989). It would be of interest to assess these parameters in infantile cerebral palsy, which is associated both with atrophic processes and with a reduction in the mediator functions of the cerebral regions concerned.

Normally (under physiological conditions), according to PET data, there is a linear relationship between the parameters of cerebral hemodynamics and metabolism. At the same time, the level of MC (cerebral blood flow) is proportional to the RCM (the volume of blood circulating in the vessels of the brain), VOC (the level of oxygen metabolism) and VOG (the level of glucose metabolism).

RCM refers to the most important parameter of cerebral hemodynamics and reflects the reaction of autoregulation of cerebral circulation in response to changes in perfusion pressure (A.G. Vlasenko, M.-K. Peti-Tabue et al., 1998, W.J. Powers, M.E. Raichle, 1985). The ability of vessels to increase the diameter is significantly limited in those blood supply basins where compensatory vasodilation has already occurred, and these areas of the brain are most susceptible to the development of ischemic damage with a further decrease in perfusion pressure due to a drop in systemic arterial pressure. Assessment of the vasodilation capabilities of the cerebral vascular system is important for the choice of treatment tactics. The reflection of the local cerebral perfusion pressure is the ratio of MK and RCM (J.M. Gibbs et al., 1984; J.W. Powers et al., 1987; U.Sabatini et al., 1991; H. Toyama et al., 1990).

With a decrease in CPP (cerebral perfusion pressure), the first compensatory response of the cerebral vascular system is vasodilation (the stage of autoregulation). At the same time, there is a gradual increase in RCM, while other indicators remain practically unchanged. When the CPP reaches the lower limit of autoregulation and the reserve capacity of vasodilation is largely depleted, MC begins to decline. Nevertheless, in this case, the SVC initially remains unchanged, which leads to an increase in oxygen extraction from arterial blood (the stage of oligemia), i.e. to an increase in FIK (fraction of oxygen extraction from inflowing arterial blood).

With a further decrease in CPP, a decrease in SVC develops, indicating the onset of the stage of true ischemia with impaired neuronal activity. In the future, this condition may undergo a reverse development (ischemic penumbra) or become irreversible (cerebral infarction). The presence of irreversible damage to the brain substance is evidenced by the VOC values \u200b\u200bnot exceeding 1.3-1.5 ml / 100 g / min. RCM increases significantly at the stage of oligemia and remains elevated, but to a lesser extent, as ischemia progresses.

Ischemic penumbra ("ischemic penumbra"). According to the modern concept of ischemic penumbra, it is a region of the brain with depressed functional activity, but preserved viability of nerve cells and is located on the periphery of the ischemic focus, which undergoes necrosis due to irreversible damage to the brain substance. The outcome of ischemic stroke largely depends on which part of the neurons in the ischemic penumbra "survive" and restore their functional activity. Therefore, the area of \u200b\u200bischemic penumbra is the main target of therapeutic action. Restoration of adequate blood flow and functional activity of neurons in this area can help reduce the size of irreversible brain damage, the volume and severity of neurological deficit, and, consequently, improve the outcome of stroke (A.G. Vlasenko, Yu.K. Milovidov, V.V. Borisenko and cit. ed., 1998).

The area of \u200b\u200bischemic penumbra is characterized by a sharp decrease in MC (below 20 ml / 100 g / min), a pronounced increase in FIC (over 0.80), as well as a moderate decrease in SV. A decrease in MC to 10 ml / 100 g / min causes a cascade of biochemical reactions resulting in cell death, i.e. the zone of potentially viable tissue is located between MK levels from 10 to 20 ml / 100 g / min (D. Krieger, 1998). The development of irreversible changes in the ischemic penumbra is evidenced by a sharp decrease in SVC with intact MC, as well as a rapid progressive decrease in FIC from high values \u200b\u200bto minimum values. The presence of an area of \u200b\u200ba sharp increase in FIK and a decrease in MC against the background of relative stability of the SVC, on the contrary, indicates the preservation of ischemic penumbra. As a rule, the fate of ischemic penumbra is decided already in the first few hours of a stroke, however, in some cases it can exist for a longer time, at least 16 hours. The volume of ischemic penumbra, which ultimately did not undergo necrosis, significantly affects the subsequent recovery, thus confirming that the “survival” of ischemic penumbra cells is key to recovery from stroke.

According to A.G. Vlasenko, J.-C. Baron, J.-M. Derlon (1998), the fact that they (by the PET method) detect signs of ischemic penumbra up to 18 hours after the onset of a stroke indicates the need to revise the concept of a universal, limited narrow time frames (no more than 6 hours) of the therapeutic window and the advisability of an individual assessment of the state of cerebral hemodynamics and metabolism when planning treatment. Unfortunately, the concept of ischemic penumbra, “therapeutic window”, “window of hope” is not being developed in perinatal neurology, in general, and in cerebral palsy, in particular.

When studying the PET method of the distant hemodynamic and metabolic consequences of stroke, A.G. Vlasenko, J.-C. Baron, J.-M. Derlon (1998) and the authors cited by them found a decrease in MC and SV in areas of the brain located at a considerable distance from a heart attack. The identification of such areas allows mapping the disturbances in the interconnection of neurons arising from focal ischemia. Traditionally, all such phenomena are united under the general name “diachysis”, although this term sometimes hides a variety of cellular disorders - from a reversible decrease in functional activity to degenerative processes, while they have in common a similar picture of metabolic changes. It has been shown that some of these disorders can be of a purely functional nature, i.e. be potentially reversible. The phenomenon of diachysis is believed to be due to functional inactivation and deafferentation of neurons both near and at a distance from the infarction and manifests itself in the form of hypoperfusion.

The phenomenon of cross-cerebellar diachysis, which consists in a decrease in SV in the cerebellar hemisphere opposite to the lesion focus, is found (by PET) in almost half of patients with cortical or subcortical strokes. This phenomenon is most often encountered and is more pronounced with extensive heart attacks in the fronto-parietal region of the cerebral cortex, as well as with subcortical infarctions with damage to the internal capsule. According to A.G. Vlasenko, J.-C. Baron, J.-M. Derlon (1998), such a topographic relationship suggests that cross cerebellar diachysis occurs due to damage to the cortical-bridge-cerebellar pathways with transneuronal functional depression.

A decrease in metabolism in the cortical regions of the left hemisphere, revealed in patients with subcortical strokes and aphasia, suggested that speech disorders may be caused by the phenomena of diachysis. The phenomena of diachysis in the form of a diffuse decrease in metabolism in the cerebral cortex of the same side as the focus are described in cases of damage to various parts of the optic hillock and, apparently, are caused by damage to the activating thalamocortical pathways. A decrease in metabolism, although less pronounced, can also be noted in the cortex of the opposite cerebral hemisphere. Since the severity of metabolic disorders correlates with the severity of cognitive impairments, it is assumed that there is a relationship between these phenomena.

PET studies have revealed metabolic effects that propagate in the opposite direction, i.e. from the cortex to the depths of the hemisphere, for example, a pronounced decrease in metabolism in the striatum and the optic hillock on the side of the cortical-subcortical stroke.

PET studies using functional speech loads allow us to study the features of speech recovery and assess the prospects for such recovery in patients with aphasia. In this case, a favorable outcome is associated with a partial preservation of speech zones in the area of \u200b\u200bcerebral infarction in the dominant hemisphere, as well as a decrease in the phenomena of diachysis in morphologically intact areas of the opposite hemisphere.

In case of progressive aphasia without dementia, a number of authors have revealed metabolic changes by PET-method, primarily in the left temporal region (P.J. Tyrrell et al., 1990). CT scan in these patients reveals an expansion of the subarachnoid spaces of the left frontotemporal region against the background of a general, but less pronounced, expansion of the subarachnoid space of the cerebral hemispheres and the ventricular system (P.J. Tyrrell et al., 1990). Over time, these patients develop dementia, which suggests that progressive isolated aphasia, which at the first stage of the disease corresponds to local atrophy of the cerebral cortex, is ultimately only the debut of a widespread atrophic process (A.S. Kadykov et al., 1996) ...

D. Kuhl et al. (1984) in a PET study conducted in 8 patients with Parkinson's disease and 14 healthy individuals, concluded that patients have a decrease in the average global rate of glucose utilization (19.9 plus or minus 4.4 mmol / 100 g / min) compared with control (25.1 plus or minus 5.0 mmol / 100 g / min). The authors showed that the regional differences in 18F-fluorodeoxyglucose metabolism in the temporal, parietal, frontal, occipital regions of the cerebral cortex, white matter, as well as in the caudate nucleus and thalamus do not exceed random values. A repeated study, carried out after a 2-week course of L-DOPA therapy, showed that the level of global glucose metabolism does not increase significantly and is manifested only as a trend, although the clinical effect was significant. Comparing the results of PET studies with the severity of clinical symptoms of parkinsonism and control parameters (volunteers of the corresponding age), it was possible to note a slowdown in the global rate of glucose utilization by up to 20% with the deepening of clinical manifestations. The expected parallelism between the decrease in the rate of glucose utilization in the striatum and the level of dopamine deficiency in the same structure, which corresponds to the severity of parkinsonism, was not found. The authors believe that degeneration of the striatum in parkinsonism does not significantly affect the rate of glucose utilization in the same structure of the brain.

This statement is consistent with the data of the study by D. Rougemont et al. (1983), in which there were no differences in local glucose metabolism in healthy individuals and in patients with parkinsonism. Changes in the content of 18F-fluorodeoxyglucose before and after treatment with L-DOPA had weak dynamics, while clinically the patients showed a significant improvement.

E. Metter and W. Hanson (1986), along with PET studies of 18F-fluorodeoxyglucose metabolism, conducted neurological, clinical and CT studies in 10 patients with symptomatic parkinsonism during speech and acoustic testing. We studied hypokinetic dysarthria, the degree of which, as it turned out, does not depend on the severity of the clinic and the variants of CT and PET manifestations.

The negative effect of hypoxia on cerebral blood flow is multicomponent: increased blood viscosity, insufficient deformability of erythrocytes, microcirculation disorders, poor tissue oxygen diffusion (G.A. Akimov, 1983). GD Dzhivelegova et al. (1983) consider the aggregation activity of platelets to be the most sensitive test for oxygen deficiency in fetuses and newborns. The specified complex of causal factors (all together or each of them separately) can, due to the difficulty of metabolic processes in the tissues of the body at the level of the microvasculature, lead to local changes in metabolism. This means that aerobic glycolysis is replaced by anaerobic, the Krebs cycle is disrupted, lactic acid accumulates, which immediately affects energy production (B.S. Vilensky, 1995). If, under conditions of aerobic glycolysis, one glucose molecule during its combustion forms 38 molecules of adenosine triphosphate (ATP), then when switching to anaerobic glycolysis, one glucose molecule forms only 2 ATP molecules. The developing acidosis, at first extracellular, initiating further intracellular, causes the disintegration of lysosomal membranes and promotes the activation of proteases. Ultimately, this "lysosomal explosion" leads to autolysis - the decay of cellular structures. Hence, the possibility of metabolic damage to the brain is understandable, often in the form of multiple foci of hypoxemic dysmetabolism.



For normal functioning of the brain, a large amount of blood is required, which is a natural transporter of oxygen. Damage to the main arteries, venous and jugular veins, due to the development of thrombosis, embolism, aneurysms, etc. leads to serious oxygen deficiency, tissue death and the loss of certain vital functions for the body. Impaired blood circulation in the brain is a serious pathology that requires urgent treatment.

Features of the blood supply to the brain

According to the most rough estimates, the human brain contains about 25 billion nerve cells. There is a hard and soft shell, gray and white matter.

The brain consists of five main divisions: terminal, posterior, intermediate, middle and oblong, each of which performs its own necessary function. The obstructed blood supply to the brain leads to disruptions in the coordinated work of departments, the death of nerve cells. As a result, the brain loses certain functions.

Signs of poor circulation to the head

Initially, symptoms of poor circulation are of little or no intensity. But as the disorders develop, the clinical manifestations become more and more evident.

Symptoms of the disease include:

If blood circulation in the brain is impaired, oxygen starvation occurs, provoking a gradual increase in the intensity of symptoms. Each of the manifestations can indicate a number of other diseases and requires an obligatory visit to a neurologist.

Causes of obstructed blood supply to the brain

The anatomy of the blood supply is complex. Oxygen and other nutrients are transported through four arteries: vertebral and internal.

For normal functioning, the brain needs to receive about 25-30% of the oxygen that has entered the body. The supply system includes about 15% of the total blood volume in the human body.

Insufficient blood circulation has symptoms that make it possible to establish the presence of certain disorders.

The reason for the development of pathology is:

Whatever the cause of circulatory failure, the consequences of violations are reflected not only in the activity of the brain itself, but also in the work of internal organs. The result of therapy is influenced by the accuracy of the established cause - the catalyst and the timely elimination of violations.

Why are the problems of poor blood flow in the brain dangerous?

A sharp violation of the blood circulation in the brain leads to serious complications. The consequences of an attack can be:
  • Ischemic stroke - accompanied by nausea and vomiting. With focal lesions, it affects the work of individual internal organs. Affects motor and speech function.
  • Hemorrhagic stroke - disorders are provoked by blood that has entered the brain area. As a result of the increased pressure, the brain is compressed, tissue wedging into the occipital foramen occurs. The high speed of blood flow in the vessels of the brain leads to a rapid deterioration in the patient's condition. Hemorrhagic stroke leads in the number of deaths.
  • Transient ischemic attack is a temporary lesion. Blood circulation can be restored with the help of medications that improve brain activity and stimulate blood formation.
    Transient attack occurs mainly in elderly patients. The attack is accompanied by impaired motor and visual function, numbness and paralysis of the extremities, drowsiness and other symptoms.
Depletion of peripheral blood flow is most often observed in the old age of the patient and leads to the development of chronic insufficient blood supply to the brain. As a result, the patient's mental activity is inhibited. A decrease in intelligence and abilities is diagnosed. Pathology is accompanied by absent-mindedness, irritability, and extremely aggressive behavior.

Impaired cerebral blood flow in children

For children, the minimum indicators of blood flow in the arteries, sufficient for normal brain function, are 50% higher than in adults. For every 100 gr. brain tissue requires about 75 ml. blood per minute.

The change in the total index of cerebral blood flow over 10% is critical. In this case, a change in the tension of oxygen and carbon dioxide is observed, which leads to serious disturbances in brain activity.

In both adults and children, several major arteries and vessels supply the brain with blood:

  • The middle cerebral artery supplies blood to the deep parts of the brain and the eyeball. The internal one is responsible for the nutrition of the cervical region, scalp and face.
  • The posterior cerebral artery supplies blood to the occipital lobes of the hemispheres. Small blood vessels that feed directly the deepest parts of the brain: gray and white matter help in this task.
  • Peripheral circulation - controls the collection of venous blood from the gray and white matter sections.
Essentially, cerebral blood flow is a special system for the circulation of blood and the transfer of nutrients and oxygen to the brain tissues. The system contains the carotid, cerebral and vertebral arteries, as well as the jugular veins and the blood-brain barrier. The areas of blood supply to the cerebral arteries are distributed in such a way as to provide abundant oxygen to each area of \u200b\u200bsoft tissue.

Control over the operation of the system is carried out thanks to a complex regulation mechanism. Since the brain tissue continues to develop after the birth of a child, new synapses and neural connections are constantly appearing, any disturbances in the blood circulation of the brain in a newborn are reflected in his mental and physical development. Hypoxia is fraught with complications at a later age.

When solving a mathematical problem or any other mental load, an increase in the speed parameters of blood flow through the cerebral arteries is observed. So, the regulation process is triggered by the emerging need for more glucose and oxygen.

Why newborns have problems with the blood supply to the brain

Among the many reasons due to which disorders of the blood supply to the brain develop, only two main ones can be distinguished:

What is dangerous for a baby with a disturbed blood supply to the head

For the normal development of a child, it is required that the volume of incoming blood in relation to the brain tissue is 50% more than that of an adult. Deviations from the norm are reflected in mental development.

The complexity of therapy lies in the fact that when prescribing drugs that improve blood circulation in the vessels of the brain, the doctor must take into account the effect of drugs on the still fragile structures of the child's life: the gastrointestinal tract, the nervous system, etc.

The consequence of a lack of blood supply is:

  1. Poor concentration of attention.
  2. Learning problems.
  3. Borderline intellectual disability.
  4. The development of hydrocephalus and cerebral edema.
  5. Epilepsy.
Cerebral circulation is treated from the first days of life. There is a possibility of death. Hypoxia negatively affects the functional capabilities of the brain and internal organs.

How to check the blood supply to the brain

Insufficient blood supply to the brain tissue is suspected in the presence of neurological symptoms and disorders. To determine the factors of damage and prescribe the necessary therapy, an additional examination is carried out using instrumental methods for studying blood circulation:

Any drugs, tablets, injections and other drugs are prescribed only after a complete examination of the patient and identification of the problem that affected the deterioration of the blood supply to the brain.

How and how to improve cerebral circulation


Based on the results of a diagnostic study, medications are selected that make cerebral circulation better. Since the cause of the disorders is a variety of factors, the course of therapy for one patient may not coincide with what is prescribed for another patient.

What improves blood circulation, what drugs

There is no single medicine to improve blood circulation in the brain that can eliminate the disturbance. In case of any deviation, a course of therapy is prescribed, which includes one or more drugs of the following groups:

Some drugs have a special purpose. So, cortexin, in the form of intramuscular injections, is recommended for use during pregnancy and after childbirth with pronounced encephalopathy. Emoxipin is used for internal bleeding. Available as intravenous injections.

New generation drugs are constantly emerging with fewer negative side effects. Prescribes drug therapy exclusively by the attending physician. Self-medication is strictly prohibited!

How to improve blood flow without medication

At the initial stage, it is possible to improve the blood supply to the brain without the help of drugs. There are several ways to influence a person's well-being:

It would be useful to include in the therapy the intake of vitamins E and C, which increase blood flow, and also visit a nutritionist in order to select an effective therapeutic diet.

Folk remedies for improving blood supply to the brain

Treatment of circulatory disorders of the brain with folk remedies does not eliminate the need for professional medical care. Non-traditional methods of therapy relieve well the symptoms of disorders:

Herbs that improve blood flow can cause bleeding. Before taking herbal tinctures, it is recommended to consult with your doctor.

Respiratory gymnastics to improve blood circulation

The set of exercises is aimed at enriching the blood with oxygen. There are several types of breathing exercises.

As with any effective remedy, exercise without proper supervision and preparation can be dangerous. The first lessons should be done with an instructor.

Breathing exercises are present in yoga and other oriental gymnastics. Compatriots also developed effective methods. So, the Streltsova method deserves a separate mention, which allows you to quickly restore the lost functions of the brain.

Exercise and gymnastics

Exercise therapy to improve the patient's well-being is aimed at the source-catalyst of the problem. During classes, the pressure and the work of the cardiovascular system are normalized.

The following types of gymnastics are best suited:

  1. Yoga.
  2. Qigong.
  3. Pilates.
  4. Pool activities, swimming.
Caution in prescribing exercises should be observed in the presence of blood clots, high blood pressure.

Diet with poor cerebral circulation

We are what we eat! Life itself proves the truth of this statement. A person's diet and eating habits have a negative or positive effect on the blood supply to the brain.

What foods improve blood flow

Foods that improve blood counts include:
  1. Fatty fish.
  2. Seafood.
  3. Dairy products.
  4. Vegetables and fruits, especially rich in iron vitamins.
The diet should include herbal remedies that improve blood circulation: oils (sunflower and olive). Plant foods, foods containing zinc are also essential to restore blood supply.

Food that is harmful to the supply of blood to the brain

With poor circulation of blood flow, you should avoid foods rich in saturated fatty acids.

The ban includes:

  1. Sugar.
  2. Sweets and flour products.
  3. Smoked and fatty foods.
  4. Flavors and synthetic condiments.
  5. Carbonated and alcoholic drinks.
A complete list of harmful and useful products can be obtained from a neurologist treating cerebral blood supply disorders.

Alcohol and cerebral circulation

Moderate doses of alcohol have a beneficial effect on the blood supply to the brain by preventing blockage of blood vessels. These are small to moderate portions.

Alcohol abuse is fatal to humans. With prolonged abuse, the likelihood of developing a fatal hemorrhagic stroke is high.

According to a recent study published in the Stroke: Journal of the American Heart Association, moderate consumption improves blood flow, while excessive consumption leads to atrophy of brain cells.

The human brain is responsible for coordinating most of the functions of our body. Circulatory disorders of the brain of any severity can provoke the development of various health problems - memory impairment, frequent fatigue, insomnia, decreased sex drive, poor concentration, etc.

Various factors affect the blood circulation in the brain, including blood pressure, blood flow velocity, the presence of diseases of the cardiovascular system, diseases of the spine, constant stress, excess weight, etc.

When there are minor disruptions or the first signs of problems with the blood flow to the brain, simple changes in lifestyle, dietary habits and physical activity can help prevent the development of serious diseases.


The most common causes of blood flow problems in the brain are:

  • Atherosclerosis - it occurs due to the accumulation of cholesterol in the vessels. With atherosclerosis, cholesterol plaques are deposited on the walls of blood vessels, which causes their blockage and narrowing of the blood flow.
  • Systematic stress. Stress negatively affects all organs and systems of a person; it can cause dangerous disturbances in the work of the brain.
  • Hypertension. With pressure drops, the heart rate is disturbed and the volume of blood pushed out by each contraction decreases, the lumen of the vessels narrows and the elasticity of the vascular wall is lost.
  • Head, neck and spine injuries of varying severity - in these cases, blood circulation is impaired due to hemorrhages.
  • Chronic fatigue syndrome. It becomes the cause of the disorder in the work of all major systems of the human body.
  • Unbearable physical activity. This is not only about excessive sports or hard physical work, sometimes an uncomfortable posture in which a person is for a long time is enough for circulatory disorders (for example, improper posture when working in an office).
  • Osteochondrosis (degenerative processes in the intervertebral discs) and scoliosis (curvature of the spine) - these diseases of the spinal column cause many pathological conditions in the body. In most cases, osteochondrosis and / or scoliosis of the cervical spine lead to impaired cerebral circulation.

Symptoms of circulatory disorders of the brain

Most often, circulatory disorders of the brain at the initial stages do not manifest themselves in any way and proceed unnoticed for a person, but with the progression of the process, alarming and very unpleasant symptoms arise.

The most common among them:

  • Frequent headaches. This symptom should never be ignored by constantly taking pain medications. It is very important to consult a specialist in time to avoid the development of dangerous consequences, including hemorrhagic stroke.
  • Dizziness and loss of balance indicate a serious lack of oxygen for the brain, if they occur, it is necessary to seek help from a doctor as soon as possible.
  • Pain in the eyes. Most often, it increases towards the end of the day and is especially pronounced during eye movements and blinking.
  • Nausea and / or vomitingaccompanied by some or all of the above symptoms.
  • Convulsions (paroxysmal, involuntary muscle contraction) and numbness(decrease or complete absence of sensitivity), which appear for no apparent reason.
  • Change in consciousness and perception. In this case, you need to immediately contact a specialist.
  • Noise and ringing or ear congestionx. The longer these symptoms are, the more serious the circulatory disorders of the brain are.
  • Fever or chills, increased blood pressure.

If you observe some or all of the above symptoms, you should immediately seek the advice of a specialist. In the case of disorders of the blood flow to the brain, self-medication is unproductive and can even harm. The specialist will send you for examination, and after identifying the true cause of the disease, he will prescribe a course of medications to improve blood circulation.

These may include:

  • drugs that prevent platelets from sticking together;
  • drugs to lower blood cholesterol levels;
  • vasodilator drugs;
  • drugs that prevent blood clotting;
  • nootropic drugs;
  • psychostimulants, etc.

Nutrition to improve blood circulation in the brain

For those who are thinking about how to improve blood circulation in the brain or avoid aggravating the problem, it is necessary to add certain foods to their diet.

These include the following product groups:

  • Vegetable oils - olive, pumpkin, linseed. For the correct and "uninterrupted" work of our brain, the body requires polyunsaturated fatty acids, which can be obtained from vegetable oils. They are the nutritional basis for maintaining the proper functioning of the brain's neurons. In addition, polyunsaturated fatty acids are effective in preventing atherosclerosis.
  • Marine and oceanic fish species - trout, tuna, salmon, sea bass. The meat of these fish species is rich in omega-3 fatty acids, which are necessary for the membranes of brain cells and protection of blood vessels from the accumulation of cholesterol.
  • Berries - lingonberries, blueberries, currants, cranberries, etc. Almost all types of berries contain many antioxidants (molecules with a negatively charged electron) - natural substances that can slow down the oxidation and aging of cells in the human body.
  • bitter chocolate with a cocoa content of at least 60%. This product contains a lot of tryptophan - an amino acid from which serotonin is formed, a hormone that prevents the development of headaches, migraines and depression.
  • Nuts - Greek, hazelnuts, almonds, cashews, pistachios, etc. They are rich in easily digestible proteins, healthy fats, vitamins and minerals, in addition, they contain essential amino acids necessary for the nutrition of the brain and the health of the human immune system.
  • Seeds - flax, pumpkin, sunflower. These foods are high in vitamin E, which has a positive effect on memory and cognitive processes. In addition, they contain a lot of omega-3 fatty acids, the benefits of which were discussed above.
  • Seafood - oysters, shrimps, mussels. These foods are rich in trace elements, in particular zinc and magnesium, which have a positive effect on attention and memory.
  • Green tea. Drinking this drink normalizes blood pressure, and the antioxidants contained in it help prevent aging of cells not only in the brain, but also in the entire body.

It must be remembered that fatty and fried foods, semi-finished products and fast food dishes provoke the accumulation of cholesterol in the vessels, which leads to their blockage and a decrease in blood flow, including to the brain.

Prevention

In addition to correcting your eating habits, you can give a few more tips that will help improve blood circulation and prevent various disorders in the brain. First of all, it is necessary to avoid physical inactivity - weakening of muscle activity as a result of a sedentary lifestyle .. With the help of physical activity adequate to your gender, age, general health and weight, you can activate the blood supply to the body, including the brain.

Thermal treatments are very helpful - sauna and steam bath, as warming up the body improves blood flow throughout the body. Various means of alternative medicine are highly effective - periwinkle, propolis, tinctures on clover and other mixtures of plants that have a positive effect on the state of the cerebral vessels.

For the prevention of cerebrovascular accidents, it is necessary to avoid factors that increase the risk of vascular atherosclerosis. Overweight, smoking and high cholesterol can lead to this disease.

For people with diseases that affect blood circulation, regular visits to the doctor are shown to monitor the state of blood flow and prevent the aggravation of its disorders.

The human brain requires a lot of blood, which naturally transports oxygen. Poor blood circulation in the brain occurs due to arterial disorders, vascular blockages and the development of blood clots.

This pathology is considered serious, because its consequences lead to the death of tissues and the termination of the vital functions by the brain. If symptoms are found that indicate poor blood circulation, you should immediately send to a specialist for an accurate diagnosis.

Signs of circulatory disorders

According to scientists, the human brain includes a large number of nerve endings and cells. Their violations lead to a variety of pathologies and diseases, as a result of which some brain functions are lost.

The first signs of circulatory disorders may not be traced at all or be so insignificant that they can be confused with a common migraine. After a while, the symptoms of impaired brain function manifest themselves more and become visible and obvious.

Symptoms of poor circulation are:

  1. severe headaches that are relieved only by taking medications;
  2. eye pain that worsens when focusing on an object;
  3. nausea and dizziness. The orientation of a person in space is deteriorating;
  4. tinnitus, the intensity of which increases every day;
  5. convulsions;
  6. fever, high blood pressure and body temperature.

In many cases, these signs are associated with psychological problems and disorders of the human nervous system. They show up for no reason. Symptoms both appear quickly and disappear quickly. It is important to know that if the slightest deviations are found, you should contact a neurologist who will prescribe the necessary treatment.

Causes of blood supply disorders


The circulatory system has a very complex structure. Oxygen and other substances are transported by arteries. Normally, the brain should receive about 25% of all supplied oxygen.

In order for it to function normally, 15% of the blood in the human body is required. If these volumes are not observed, then over time, circulatory disorders are inevitable. This is a serious pathology caused by various diseases of the circulatory system.

One of the most common diseases is vascular atherosclerosis. It is mostly common in people of old age or in people with poor metabolism. The disease leads not only to disturbances in the blood supply to the brain, but also to poor blood circulation in the body.

Hypertension also leads to disturbances in the functioning of the brain. This is due to systematic pressure drops. The processes affect the work of blood vessels and have a bad effect on the work of the blood supply. Depression, fatigue and nervous disorders over time lead to abnormalities in the brain.

If a person has previously had injuries or operations on the skull, then after a certain time he may feel some deviations. The physiological reasons for disruption of the blood supply include sedentary work, increased engagement in any kind of sports, spinal injuries, scoliosis, and others.

In order for the body and all its organs to function normally, you should be examined by a specialist every year and monitor your health. This is especially true for people at risk.

The cause of the pathology is not as important as timely consultation with a doctor and high-quality treatment, because violations can affect the work of the brain and the work of the body as a whole, its internal organs.

The danger of disturbances in blood flow in the brain


Violation of blood circulation leads to seizures, the consequence of which can be ischemic stroke.

First symptoms - this is nausea and vomiting. In severe cases, some internal organs are affected.

Its consequences - This is a violation of speech and musculoskeletal system. Transient attacks occur in older people. During them, a person's motor function is disturbed, vision is lost, paralysis of the limbs may occur.

Hemorrhagic stroke leads to impaired blood transport to the brain. In these cases, the blood circulation rate increases, which leads to a sharp deterioration in the general condition of the body. The type of stroke is common among older people and is often fatal.

All strokes lead to the development of pathologies. In old age, such people may experience chronic disturbances in the blood supply to the brain, as a result of which the patient may lose memory. At best, only mental activity and intelligence are reduced. These are not all the consequences that can be found in people who have experienced a stroke and various attacks.

Circulatory disorders in children

Despite the fact that pathologies in the work of the blood flow occur most often in the elderly, there are cases when children also suffer from various diseases. A child's brain requires a higher percentage of blood and oxygen than an adult's. Deviation from the norm leads to serious disorders and changes in brain activity.

In terms of structure, the brain of a child is no different from that of an adult. It has arteries and vessels that carry out brain activity. Poor cerebral circulation in children has the same symptoms as in adults.

The development of brain tissue occurs after birth, so changes in the brain can occur during this time. If a sign of a violation is detected, you should immediately go to the hospital for examination, so as not to miss the development of serious diseases, because they can affect the mental development of the child.

Among children, brain dysfunction is most often found in newborns. This is facilitated by pathologies that have arisen if there was insufficient oxygen supply to the child in the mother's womb. The mother's injuries, her bad habits and infectious diseases can also affect the development of the newborn.

An important role is played by genetics and the incompatibility of the blood group of the mother and the child.

Birth trauma, suffocation, prematurity of the child can cause impaired blood circulation in the brain. Usually, the consequences are not long in coming and can manifest themselves during the first year of life.

A child is more susceptible to disease than an adult, and therefore treatment will not be easy. Its difficulty lies in the fact that all internal organs have not yet fully developed, and it is not known how they will react to the therapy proposed by the doctor. Medicines must be selected carefully so that not a single vital system is affected.

It should be borne in mind that the consequences of poor blood flow can haunt a child for a long time, or even a lifetime. They can be different, ranging from a difficult understanding of school material, ending with cerebral edema and epilepsy, so there is no need to delay treatment. It can be provided already in the first days of life, but the risks are great. With pathologies of the brain in newborns, a lethal outcome is possible.

Diagnostics of the blood supply to the brain


At the first signs of an abnormality in the work of the brain, you should contact a specialized clinic for diagnosis and treatment. Once a year, healthy people who do not show any symptoms indicating a disease need to be examined. This must be done in order to detect the problem in time, if any.

Diagnostics is carried out in various ways. The first is an MRI of the brain. This type of examination allows you to see the condition of the tissues and find out how much the parts of the brain are affected. This method is one of the most effective, because it allows you to see even the nerve trunks and membranes. Newborn babies are prescribed neurosonography. Diagnosis is carried out through the not yet overgrown fontanelle.

There are many more types of examinations that a doctor can prescribe. He looks at the patient's condition, his symptoms and, based on this, determines the type of diagnosis. After that, pills and other drugs are already prescribed that can restore the work of the blood supply to the brain.

Prevention


There are many ways and means to prevent diseases. They are used in both traditional medicine and folk medicine. In the traditional one, diagnostics are carried out first. Only then the doctor looks at the state of the cerebral vessels, draws certain conclusions and prescribes drugs for prevention. They are always selected on an individual basis, because what suits one patient will not suit another.

Basically, drugs are prescribed that improve the blood supply to the brain. Only after their systematic use can improvements be achieved. Usually, a whole course of drugs is prescribed, because there is no medicine in nature that can independently eliminate all problems related to the functioning of the brain.

The doctor can prescribe both pills and injections. They all affect the arteries and blood vessels. In some cases, they expand them, and in some, on the contrary, they narrow them down. For prevention, some pregnant women are prescribed drugs that allow the child to be born healthy, even if abnormalities are detected during ultrasound. In any case, you can not self-medicate. It won't end well.

In medicine, there are many ways to prevent various diseases, and disorders associated with the work of the brain have not been spared. All funds are used exclusively for preventive purposes, when the disease has not yet occurred. Before that, you need to consult with a specialist.

First group drugs for prevention are originally from India. They consist exclusively of herbs and help to strengthen the general condition of the body. Tea is made from plants and consumed every day. The results of treatment can be said by the fact that in India there are many long-lived people.

Second group Are dietary supplements that improve blood circulation. The preparations contain herbs, vitamins and minerals. They are absolutely safe and suitable for the prevention of various diseases. They need to be taken together with a balanced diet. Only then will the result be noticeable.

Third group Is homeopathy. Doctors have long debated the benefits of homeopathic medicines. Some even believe that they cannot be called medications, but rather supplements. Their goal is to improve the immune system, which will improve the general condition of the body and protect it from viruses and infections.

Many doctors advise massage as a prevention of many diseases. With the help of it, blood flow improves, a person relaxes. It is also prescribed if blood clots are suspected. Vitamins C and E are added to all treatment complexes. They have a beneficial effect on the circulatory system. People who are obese and overweight should visit a nutritionist for prevention, who will prescribe a therapeutic diet.

In folk medicine, there are remedies that help to establish blood flow. If a person suffers from dizziness, then a clover-based tincture can help him, which is recommended to be infused for about three weeks, and taken at night and before meals. If you have poor circulation, you can use chestnut tincture. Herbs also improve the overall health of the body. Any tinctures and decoctions can be taken if the doctor has given permission to do so.

Physical activity and diet


As you know, physical activity can improve the condition of the human body and body. Daily morning exercises, walks in the fresh air will help normalize blood circulation in the brain. For this, doctors recommend breathing exercises. For quick results, you can contact a trainer, but you can do it at home. All breathing exercises are in yoga and pilates.

People who already suffer from diseases associated with blood circulation in the brain should engage in physiotherapy exercises or swimming. Before training, you need to tell about your symptoms and diseases not only to the doctor, but also to the coach. Then he will select those exercises that will be effective and safe.

When there is poor blood flow to the brain, nutritionists recommend monitoring your diet. Only a daily correct diet can both improve the condition and worsen it. There are many foods that improve blood circulation. In order to improve your health, you need to eat fish, seafood, fruits, vegetables, olive oil every day. Dairy products also have a positive effect on the body. Only quality foods should be consumed.

There are foods that, on the contrary, harm the blood circulation in the brain. They are most often loaded with unhealthy substances such as cholesterol and unhealthy fats.

You should refuse such products:

  1. sugar;
  2. smoked meats;
  3. products with synthetic flavors;
  4. flour;
  5. sweet carbonated drinks;
  6. alcohol.

Alcohol abuse is very harmful not only for blood vessels, but also for the entire human body. This addiction causes addiction and various diseases associated with blood circulation. People with alcohol dependence are prone to strokes and heart attacks. Drink alcohol only in moderation.
