It turns out that every fifth or sixth person has various disorders of the nervous system. Some of them are generally individual in nature.

Although science has advanced far in the study of the human nervous system, primitive and erroneous ideas about the causes of the above problems and their elimination are common everywhere.

Even the health workers themselves do not have enough education, so myths live. Here are the most persistent misconceptions.

All nervous disorders are based on stress. If this were the case, then the disorder would never arise in completely well-off people. Life says otherwise. Stress can indeed be the source of nervous breakdowns. But for this it must be either very long-lasting or strong. In other cases, stress is responded to by those people whose nervous system was damaged before that. Nervous loads just make the hidden obvious. For a weakened nervous system, such "stress" can be a wide variety of things - an open tap, an insignificant domestic quarrel. And how many examples of how people who have been in difficult conditions and circumstances for a long time only strengthened their spirit and body. The difference is whether the nervous system is healthy or is already impaired.

All diseases are from the nerves. This is a fairly old and popular myth. But if it were true, then any army after a month of hostilities would turn into one big infirmary. After all, a real fight is the strongest stress that should cause illness in all participants. In practice, however, such a massive character is not observed. And in civilian life there are professions that are associated with high stress on the nerves. We are talking about teachers, doctors, service workers. But even among them there is no total morbidity. The very principle "all diseases are from the nerves" understands that diseases appear by themselves only due to a violation of nerve stimulation. The man was healthy, but the experiences gave rise to pain in the heart. But it is impossible to assume that nervous loads have become the source of the disease. Most diseases are latent and are not always accompanied by pain. And they show when the body experiences an increased effect, including the nervous one. For example, a bad tooth may not give itself out until cold or hot water gets on it. The same heart may be affected by a disease, but in the first stages there will be no pain or discomfort. Only with the help of a cardiogram it is possible to study its work, and even then it is not always accurate. In the diagnosis of other internal organs, it is also not so simple. So it’s impossible to assume that all diseases come from nerves. It's just that nervous overload puts the body in such a position when the already present diseases make themselves felt.

In case of nervous disorders, it is necessary to take only drugs that will directly affect the nervous system. It is worth asking the question, what should be treated if animals in the park are sick - animals or a park? Could it be that diseases of internal organs only harm themselves? Wouldn't disruption to the activity of one organ affect the entire organism? The human nervous system is an important part, as is the cardiovascular system, for example. There are many diseases that are born directly in the brain. To treat them, you must take medications that affect the brain tissue. But most often neuropsychological problems arise due to physiological disorders, poor biochemistry. Diseases of the internal organs affect the blood circulation in the brain and the nervous system in general. If you do not maintain a constant blood composition, then after a while there will be disruptions in the biochemical processes that ensure the functioning of the brain. This is how nervous disorders appear. By the way, they can generally be the only sign of an internal organ disease. So it is necessary to look for the cause of malfunctions in the nervous system and treat the source of the problems.

If the vitality is weakened, then it is necessary to take special means, adaptogens (Eleutherococcus, Rhodiola rosea or pantocrinum). Such tonics cannot eliminate any reason for the drop in vitality. Adaptogens can only be taken by healthy people before impressive physical or nervous stress. If these funds are taken by people with an already weakened nervous system, then this will lead to an even greater depletion of internal reserves. Doctors believe that tonics can alleviate the patient's condition only for a short time, using the individual's possible body.

Purposefulness and other qualities of a person depend only on him. A thinking person understands that this is not entirely true. Scientists say that special areas of the brain, the frontal lobes, are responsible for purposefulness. There are many ways to disrupt their normal state. For example, if there is poor circulation in this part of the brain. This will not affect thinking and memory. The person becomes unassembled, loses concentration and will to achieve goals. Disturbances in different parts of the brain can cause different psychological abnormalities. So to think that a person creates character for himself is not entirely correct. Moreover, the main features are laid down by about 4 years. But in this period of life people do not remember themselves well. So the basis is formed almost without taking into account our wishes. Positron tomography showed that each type of character in healthy people corresponds to a certain activity of blood flows in different areas of the brain. The same principles divide people into introverts and extroverts. For reasons independent of us, individual characteristics, handwriting, gait are formed. And you can get rid of unwanted traits not by a simple effort of will, but by eliminating what interferes with the normal functioning of nerve cells.

Depression appears due to difficult life circumstances or incorrect, negative thinking. In fact, not everyone's difficult living conditions end in depression. In the case of a healthy nervous system, as a rule, changes in lifestyle are tolerated without much damage. The creation of depression by bad thoughts is impossible, usually the opposite is true. First, it comes, and then plausible explanations for such a state come into my head: "Everything is bad", "Nobody loves me", "There is no sense in life" and so on. Depression is the result of impaired activity in brain cells. It happens that great grief also generates it. But in this case, mental wounds will heal over time. That's when they say that time heals. And it is quite difficult to define depression in oneself - it is constantly hiding. Even those who are aware of their susceptibility to this condition may not always recognize an exacerbation.

If a person cannot get rid of smoking, then the problem is in his nerves and weak willpower. It is known that the components of tobacco smoke over time begin to participate in the biochemical reactions of our body, gradually displacing natural substances. Smoking rebuilds the nervous system so that it becomes addicted to more and more servings of nicotine. In theory, when you quit smoking, the brain changes that will allow you to return to your previous state. In practice, however, this happens only in those whose nervous system has high adaptability and the ability to adapt to new conditions. And according to statistics, the ability to adapt is reduced in about 30% of people for reasons beyond their control. Reactions take place at the cellular level, so sometimes it is impossible to improve your adaptive capabilities by willpower alone. There are cases when people continued to smoke even in cardiology, under the threat of a second heart attack. So people with reduced adaptability who want to quit smoking can be advised to take drugs that activate and improve the functioning of the brain, up to antidepressants. The situation is similar with alcohol. And the adaptive possibilities are not unlimited in people with a healthy nervous system.

Nerve cells are not restored. According to this myth, all our experiences, anger, negative emotions, entail irreversible changes in the nervous tissue. But cell death is actually a natural and ongoing process. They are renewed in the brain at different rates in different parts of the brain, from 15 to 100 percent per year. And stress "kills" not the cells themselves, but those substances that help them interact with each other (neurotransmitters). This can lead to a lack of such substances, which will translate into a long-term nervous breakdown. However, these substances are irretrievably consumed by the brain in general during any mental processes, during thinking, communication, pleasure. The natural mechanism works clearly - if there are a lot of impressions, the brain refuses to accept them. Examples of this are the ancient rulers, fed up with pleasure, the workers of the confectionery factory, who hated candy.

Laziness is the invention of those who do not want to work. They say that a person has three natural instincts - self-preservation, procreation and feeding. In fact, there are many more such instincts. One of them can be called as "saving vitality." Although there are a number of people who experience a constant craving for work, usually people are generally lazy and incurious. So laziness is a common instinct to save vitality and unwillingness to spend it on what seems to be unnecessary activities. The frequent appearance of such a feeling indicates, first of all, that the body has reduced energy reserves. In chronic fatigue, laziness and apathy are classic companions, but this indicates an unhealthy state of the body. Quite a lot of energy is spent on internal processes - maintaining a constant temperature, heart contraction, breathing. And the appearance of laziness along with apathy suggests that the body includes biological protection against the waste of its vitality due to their lack. But misunderstanding of this mechanism provokes conflicts, some even begin to blame themselves.

If you give the body a rest, then chronic fatigue will pass. It happens that even in healthy people who work hard every day, strength is fully restored only after a night's sleep. And some even feel a feeling of fatigue, although as such they do not experience a muscle load. The key lies in the fact that the release of energy or its formation can be disrupted at any stage for a variety of reasons. For example, the thyroid gland will become less functional. As a result, metabolism and energy slows down. Unfortunately, such nervous disorders are simply ignored by psychiatrists. But every seventh patient referred to a psychotherapist or psychiatrist actually suffers from thyroid dysfunction. It is quite obvious that no rest will help in this case.
