Is depression divided into physiology and psychology? Is physical depression the brain can't recover?

Hello, your question is very good. In fact, there is no difference between physical and psychological depression. We can take physiology and psychology as the content of the pathogenesis of depression, which is the result of the interaction between physiology and psychology.

Pathogenesis of depression

The pathogenesis of depression has been mentioned many times before, so here is a brief review. The pathogenesis of depression must not be a simple psychological problem, so it must be determined first, because even under great and serious mental stress, some people will still get sick under the same pressure, and some people can maintain mental health under the same pressure. It can be seen that simple psychological factors can not directly lead to the onset of depression. Here we should consider the other two main factors-genetic factors and biological factors. The occurrence and development of depression is inevitably directly related to heredity, but it is different from the traditional genetic disease. Heredity here refers to genetic susceptibility. For example, people with depression in first-degree relatives are about 10 times more likely to suffer from depression than ordinary people, but they are still not absolutely sick.

My own understanding: when you say psychology, you mean depression caused by obvious psychological factors. If the duration is long enough and there are enough depressive symptoms that meet the medical diagnostic criteria, it is depression, not psychological depression. No matter what the cause of depression is, as long as you really reach the diagnosis of depression, you will find that if the cause of depression is solved in time, depression will not disappear, the cause is gone and the symptoms are still there. So there is no physiological or psychological difference between depression.

Can't the depressed brain recover?

Severe depression may achieve what you said, because the essence of depression is a chronic disabling disease. Long-term uncontrolled persistent symptoms of depression will cause irreversible changes in cognitive function, which can be understood as the main function of our brain, so severe depression may cause irreparable damage to the brain.

Of course, depression can be completely restored to normal during the general remission period. For example, 50% of patients can be completely cured after the first attack with a full course of treatment with sufficient dose. Even if it can't be completely cured, the symptoms will be relieved or completely disappeared with the help of different drugs. Sometimes the therapeutic effect of drugs is not necessarily good, but clinicians will generally change the therapeutic drugs with unsatisfactory effect after 3-4 weeks, and will also consider choosing two drugs with different mechanisms for combined application when one drug is unsatisfactory.

As long as we adhere to the scientific treatment method of combining drug therapy with psychotherapy, I believe that the possible irreversible changes in cognitive function can be avoided.

I hope my answer is helpful to you. It's not easy to hit by hand. Thank you for reading.

Is depression divided into physiology and psychology? Is the brain unable to recover from physical depression?

Depression (depressive episode) has different classification methods according to different angles. For example, according to the etiology, it can be divided into endogenous depression and exogenous depression, or primary depression and secondary depression; According to the severity, it can be divided into mild, moderate and severe depression; According to the characteristics of specific symptoms, it can be divided into reactive depression, postpartum depression, menopausal depression, psychotic depression, seasonal depression and so on. Of course, there are two most common manifestations of depression, namely, simple depressive episode and depressive phase in bipolar disorder. I think the physiological and psychological meaning of depression mentioned in the question may refer to primary depression and secondary depression.

However, these are not important, what matters is the solution! Absolutely! Ask! Question!

Secondary depression

Whether it is drug-induced depression caused by some drugs, depression caused by some physical diseases, or depression caused by strong physiological and psychological factors, in the final analysis, the reasons can be found. As long as these secondary factors can be solved, and appropriate antidepressants and psychotherapy can be used, certain effects can be achieved.

Primary depression

Primary depression is far from being as terrible as people think. On the contrary, the author thinks that this kind of depression is often easier to solve than secondary depression. Because some minor factors are difficult to solve (sudden death of relatives, incurable malignant diseases, etc.). ), antidepressant treatment is often difficult to achieve satisfactory results. Primary depression is related to the decrease of neurotransmitters 5- hydroxytryptamine and norepinephrine in synaptic space of central nervous system. Then we now have a variety of drugs, whether single-channel or dual-channel or other types of antidepressants, which can effectively solve this problem, and the first physical therapy methods such as non-convulsive electroconvulsive therapy for severe depression are the "magic weapon" to solve this problem quickly and effectively.

Depression, as the fourth largest disease in the world, has always ranked first in the black list in suicide mortality. Not to mention how many excellent writers, artists and scientists have fallen under its clutches, it is really a pity to see those white-collar elites, fancy teenagers and the elderly who are imprisoned by depression all day in their daily clinical work. Fortunately, with the continuous improvement of medical level and the in-depth study of antidepressant treatment, the cure rate of depression has also been greatly improved. Finally, it is emphasized that if you suspect that you have depression, you must go to a specialist hospital for treatment. If the wound needs debridement and dressing, you can't stand it. Our experts will definitely make the most suitable comprehensive treatment plan for you to improve your quality of life. Please cherish every day and every moment of your precious life.

Is depression divided into physiology and psychology? Is physical depression the brain can't recover?

Depression is a very common mental illness, which generally leads to anxiety after experiencing some failures or physical discomfort, giving people the illusion that depression is caused by physiological problems, but in fact anxiety is caused by some physiological problems, and the sense of anxiety is getting higher and higher. People will have many physiological reactions after anxiety, that is, physical symptoms, such as chest tightness, shortness of breath, headache and dizziness, frequent urination and urgency. Everyone is different. Depression is not caused by physical symptoms, but by physical symptoms.

Depression is anxiety caused by some unreasonable cognition, especially high anxiety caused by extremely low self-evaluation. Helping patients to change their self-evaluation and objectively analyze problems can reduce anxiety, and then fixing the correct cognitive thinking mode in the brain through positive suggestion can eliminate symptoms and restore to the original state, including the level of thinking. For some particularly outstanding and motivated patients with depression, it may be better than the original state.

First, depression also has a biological basis.

Maybe you think depression is a kind of "heart disease". Of course, "heart disease" needs a "heart medicine" doctor. Depression only needs psychotherapy, not chemotherapy.

However, a series of scientific evidences show that depression is also a disease with biological basis. Show in:

1) At first, the onset of depression was related to various negative events in life (such as abuse, bad family environment, bereavement, divorce, etc.). ).

However, after repeated episodes of depression, patients may be "unhappy for no reason" and "originally fine, suddenly eroded by depression". The occurrence of depression is not closely related to unpleasant events.

2) After long-term recurrent depression, the brain structure and function of patients will change. Typically, the volume of hippocampus in patients' brains will decrease with the increase of depressive episodes, and hippocampus is closely related to our cognitive function.

Many research results have found the physiological basis of depression, although it is difficult to judge whether depression causes the physiological changes of patients or the physiological changes of patients. But what is certain is that depression is not only a simple psychological problem, similar to common physical diseases, and biological factors also participate in the pathological process of depression.

Second, psychotherapy and medication are two aspects of depression treatment.

Compared with well-known physical diseases, depression is very special. Although there are biological factors involved, psychological and social factors also have great influence on it. It can be said that depression is a disease caused by biological, psychological and social factors.

The treatment of depression is essentially the intervention of its pathogenic factors. Both drug therapy and psychotherapy can be used as treatments for depression, but their effects are different.

Third, the core of choosing psychology or drug treatment lies in the patient's disease characteristics.

After being diagnosed with depression, psychiatrists will evaluate the severity of the patient's illness and the characteristics of the disease, so as to recommend appropriate treatment for the patient.

Guidelines in most countries believe that patients with mild depression only need to receive psychotherapy alone. However, the guidelines of the American Psychiatric Association suggest that patients with mild depression also need medication.

However, for patients with moderate and severe adult depression, especially those with psychotic symptoms, or those with self-mutilation, suicidal attempts or behaviors, national guidelines suggest that they receive medication to effectively and quickly relieve their symptoms. At the same time of drug treatment, it can be combined with psychotherapy to achieve better therapeutic effect.

First of all, I want to emphasize again that scientists don't know the root cause of depression or any other mental illness. At present, there are only many interesting theories, but no evidence has been found for any of them. But maybe one day we will find the answer. At that time, when we look back at this era, we will find that it was ridiculously backward. But in any case, there will definitely be a breakthrough in this scientific field, and the research on the brain will develop at an explosive speed. There is no doubt that in the next 10 years, all kinds of new theories will not appear.

The brain is an extremely complex system, and our understanding of the working principle of the brain is still in the primitive stage. We still have too many unsolved mysteries about the "hardware" and "software" of the human brain. How does a nerve or a series of nerves turn stimulation into thinking or feeling? This is one of the most difficult scientific mysteries. To me, this question is as mysterious as the origin of the universe.

Some scientists have put forward a hypothesis that depression may be due to the lack of one or more of these biogenic amine transmitters in the brain, while mania (excessive euphoria or excitement) is due to the excessive dryness of one or more of these transmitters. Some researchers believe that serotonin has the greatest influence on depression; Other researchers believe that norepinephrine or more abnormalities will also have an impact.

According to these biogenic amine theories, we can draw a conclusion that antidepressants may be effective because they can increase the contents of serotonin, norepinephrine and dopamine in patients with depression, or make them more active. What if there were no chemical messengers such as serotonin? Then, this nerve can't send its own nerve signal to the postsynaptic nerve correctly through the synapse, and there will be a connection failure in the middle of the brain. This will cause people's mental and emotional disturbances, just like the music made by the loose tuning line of a radio. There are two kinds of emotional interference, one is because of insufficient tryptamine, which will lead to depression; The other is because too much serotonin can cause mania.

The theory of this amine has changed a little recently. Some scientists no longer believe that insufficient or excessive serotonin can lead to depression or mania. Instead, they began to assume that emotional disorders were caused by abnormalities in one or more receptors on the nerve membrane. It is considered that there is something wrong with the 5- hydroxytryptamine receptor on the postsynaptic nerve. For example, there are not enough receptors, so how can nerves communicate with each other? Although there may be many serotonin molecules in the synapse, when the presynaptic nerve sends out a signal, the postsynaptic nerve cannot send out a corresponding signal. What happens if there are too many serotonin receptors? This may have the opposite effect, that is, the serotonin system will be too active.

So far, we have found that there are at least 15 different types of serotonin receptors in the brain. As time goes on, we will find more types. All these receptors may have different effects on hormones, feelings and behaviors. However, as to what role these different types of receptors play, and whether they will cause depression or mania if they are abnormal, scientists have not yet a very clear concept. Although there are many kinds of these 5- hydroxytryptamine receptors, the research in this field has developed very rapidly. Maybe in the near future, we can better understand their physiological and psychological effects.

What role does serotonin receptor play in brain function? Although we know little about this, there is evidence that the number of receptors on postsynaptic nerves may change when antidepressants are used. For example, if the drug you take can increase the amount of serotonin in the synapse between nerves, the number of serotonin receptors on the postsynaptic nerve membrane will decrease after a few weeks. This may be due to the compensatory measures taken by nerves to avoid excessive stimulation; In other words, the nerve will try to reduce the number of signals. This reaction is called "down regulation". On the contrary, if you reduce the serotonin in the presynaptic nerve, the serotonin entering the synapse will also decrease accordingly. After a few weeks, postsynaptic nerves may take compensatory measures to increase the number of 5- hydroxytryptamine receptors; Nerves will try to increase the number of signals. This reaction is called "up-regulation".

These terms sound professional, but their meanings are simple. "Up-regulation" means "increasing receptors" and "Down-regulation" means "decreasing receptors". I can also say that "Up" means to turn up the volume, and "Down" means to turn down the volume-just like adjusting the volume of the radio. As we all know, antidepressants usually take weeks or even months to work. The researchers tried to find out why. Some researchers believe that "down-regulation" may explain the therapeutic principle of antidepressants. In other words, antidepressants may be effective, not because they can up-regulate the serotonin system as previously thought, but because they can down-regulate the serotonin system after a few weeks. This may explain that the reduction of serotonin is not the root cause of depression at all. On the contrary, depression may be caused by the increase of serotonin activity in the brain. Antidepressants or actions solved the problem a few weeks later, because it could down-regulate the serotonin system.

Are these theories reliable? Is there any evidence? No, they're just hypotheses. As I said, it is too easy to come up with a theory, but it is difficult to find evidence. So far, it can't be confirmed or denied because there is no convincing evidence. In addition, there are no relevant clinical or laboratory tests at present, so we can't accurately find any chemical imbalance in the brain of a group of patients or a single patient that leads to depression.

The main value of these theories at present is to stimulate the interest of researchers, so that over time, we can learn more about the working principle of the brain. I believe that one day we will put forward more reliable theories and provide powerful tools to test these theories. Maybe you think, "That's it?" Scientists seem to just sit and dream, saying that depression may be caused by excessive or insufficient transmitters or receptors in the brain. "Is that all they can do? To some extent, this is the only way. Part of the reason for this problem is that we still know very little about the brain, so our theory about depression is far from mature.

Maybe depression is not caused by any chemical transmitter or receptor. Maybe one day we will find that depression is actually more like a "software" problem than a "hardware" problem. In other words, if you have a computer, you will know that it will crash at any time. Sometimes it's because of hardware problems. For example, maybe your hard disk is out of order. But more often, the crash is due to software problems-in some cases, the program may run incorrectly because of loopholes. Therefore, when studying the relationship between depression and the brain, we may always think that it is a "hardware" problem (such as congenital chemical imbalance), but the real problem lies in "software" (such as negative thinking patterns caused by cognitive errors). These two problems are "organic" because they are related to brain silver, but the solutions are quite different.

In addition, experts who study depression must also deal with a key question, that is, which comes first, the egg or the chicken. Are the changes we find in the brain the cause or the result of depression? To illustrate this problem, let's do a meditation experiment first. Please imagine a lively and happy deer in the Woods. Suppose we have an advanced machine, through which we can see the chemical and cellular activities in the deer brain. For example, we have a convenient future brain imaging machine, which can work from a distance, just like a laser gun used by traffic police to measure driving speed. However, the deer certainly didn't know that the child was monitoring its brain activity. Suddenly, it found a group of hungry wolves approaching it, so it was shocked. At this time, our brain imaging machine can detect that the brain electrical activity and chemical activity of deer have changed greatly. Are these chemical changes and EEG changes the cause or result of fear? Can we say that the deer is afraid because the chemicals in its brain suddenly lose balance?

Similarly, the brain of patients with depression also has various chemical changes and EEG changes. When we feel happy, angry or afraid, our brains will change greatly. What are the brain changes that cause these strong emotions? And what kind of brain changes are the result of these strong emotions? For experts who study depression, one of the most painful challenges is to distinguish causality. This problem is not unsolvable, just too difficult. Although we would like to accept the current theories of depression, we can't find any evidence.

Obviously, in order to verify any of these theories, research is needed, and this kind of research work is extremely difficult. The biggest problem is that we can't accurately understand the chemical process and EEG process in the human brain at present. We can't open the head of a depressed person to observe the changes inside! Even if we can, we don't know where and how to find it. However, advanced tools, such as PET (positron emission tomography) and MRI (magnetic resonance imaging), make the research in this field possible. Therefore, scientists began to be able to "see" the neural activities and chemical processes inside the human brain. This is undoubtedly a great discovery. However, the research in this field is still in the primary stage, and we can only hope that there will be more development after 10.

Depression is a disease caused by long-term psychological depression. Depression can be roughly divided into endogenous and exogenous, psychological depression is exogenous, and physiological depression is endogenous. Depression is very common in today's society, and everyone has the possibility of suffering from depression. So we should keep a good attitude and live an active life. Even if you are unfortunately sick, you should actively cooperate with the treatment and don't give up easily.

Depression is a mental disorder caused by the change of internal and external factors, and some patients will have other mental diseases over time. Most depressive diseases are more likely to recur, and most of them will be relieved or transformed into chronic diseases through treatment. The origin of depression is complicated, and there is no clear conclusion at present. At present, medicine can only judge that depression is the result of genetic factors, hormonal changes in the body and environmental stimuli. Depression ranks the fourth largest disease in the world, but the understanding and treatment of depression in China is still at a very low level, which requires us to correctly understand depression and maintain a positive attitude towards life.

According to the main influencing factors of depression, depression can be divided into endogenous and exogenous. Most people's psychological depression refers to exogenous depression, which is mainly caused by external environmental stimuli, such as the breakdown of love, friendship and family ties, the failure of career or natural disasters such as earthquake and tsunami, and other fatal blows, leading to depression and collapse. In life, psychological depression is more common than physical depression, and patients with psychological depression are often unable to face setbacks in life or are in a state of suppressing themselves for a long time.

So how to prevent depression? We can keep a healthy and positive attitude towards life and good living habits, and find a meaningful thing to do according to our own interests to keep ourselves busy. Even if you are unfortunately sick, you should actively cooperate with the treatment and try to live.

Depression is related to the date of birth, the toxicity of western medicine and the onset.

Western medicine itself is one of the causes of depression. Western medicine is pseudoscience and can't find the cause, so western medicine can't cure depression.

The main symptoms of depression are tight forehead and unconsciousness on the top of the head. I've been depressed before, and it's a terrible taste. I cured it with Chinese medicine.

Interview with Jia and Zi Gui: How to Cure Depression

Moderator: Hello, parents, teachers and friends on the Internet! Today, we are fortunate to invite the expensive teacher Li Xingfu to explain the relevant knowledge of depression treatment.

Hello, Miss Li. Judging from the current situation, the incidence of depression in China is very serious. What do you think of this?

Teacher Li Xingfu: Yes, according to the statistics of relevant departments, the incidence of depression among adolescents in China has reached more than 8%. According to statistics, adult depression is said to have reached more than 200 million. Therefore, depression is a common problem in today's society, which has affected people's daily life and study.

Moderator: Teacher Li, what do you think is the reason why China people suffer from depression in a large area?

Teacher Li Xingfu: I think so. I think the emergence of depression has something to do with our culture. In other words, our nation is a nation with excellent traditional culture, which is hidden in the genes of everyone in our Chinese nation. However, over the past 100 years, we have learned a lot of western culture and accepted the indoctrination of western culture, so we have not learned excellent traditional culture. Therefore, the cultural conflict between western culture and our blood genes is actually a conflict of values. For example, the training and scenes in big cities are full of excitement, which have been completely changed by American psychology and behavioral science, but have not actually solved people's ideological problems. Psychological counseling can't solve the problem of depression. However, with the rapid development of the real society, old problems have not been eliminated, and new problems are constantly emerging, so she has contradictions in her heart. In this way, the interpersonal relationship, career development, marriage, education and other problems of people with psychological problems are becoming more and more serious. After a long time, they continue to be depressed, which is basically the case. This is an adult situation.

Then, the child's part also shows that traditional culture is not popular, and he is not well educated, so he is depressed. This is my understanding. This is the same as the adults mentioned just now. When we observe, we will find a phenomenon: if a child is depressed or depressed, you will see that the parents of this family, especially the mother, have said some wrong and absurd words to the child since childhood, in other words, the child has not heard a few correct words. Because the child's cognitive ability is weak, if the parents say something wrong, he can't tell it in time. He used his own value judgment to define what his parents said, so after defining such a language sentence, he stored it in his brain. The brain has a mechanism that is generally not easy to delete after storage. If there are 200 false messages like this stored in children's brains, we assume that our children will break into adult society with these unhealthy beliefs and communicate with others, classmates and teachers, which will lead to fierce conflicts. Some children will show this conflict in the form of violence, while others will not say it, and then they will keep this conflict in their hearts for a long time. Then, they will be depressed.

In other words, it is reasonable to say that most of them are older children, but sometimes he knows what is right and wrong, because these wrong beliefs defined by him as a child will always interfere with him, making him unable to accept correct information or new things, and he can't adjust these beliefs in his mind, so he can't integrate with the people around him, which will lead to conflicts. Once that kind of natural behavior can't keep up, it will fall behind greatly. Then, he will be marginalized in the class. When he comes home, his parents don't understand him, and he will still be depressed when he gets home. He will be depressed at school and at home. After a long time, he dropped out of school. This is a basic cognitive view of my research on adolescent depression.

Moderator: So, Miss Li, in today's society, the problem of depression has become a headache for social families. High incidence, involving a wide range of people. In today's society, we are all more or less depressed because of the great pressure of people's survival. So for the treatment of depression, it can be said that there are many means and methods, and even drugs will be used in severe cases. So, do you think these depression therapies in society can really work?

Teacher Li Xingfu: Well, if a child has depression, especially mania, he must use drugs. Elderly patients hurt people by smashing furniture. You can't control it without medication. But with drugs, it can only play a role in alleviating. That is to say, after taking this medicine, it has a soothing effect and temporarily eliminates its manic mood and unhappy feeling, but its fundamental problem has not been solved. In addition, when the manufacturers studied these drugs, they did not promise you that they could cure depression. Therefore, we will find that many patients with depression have stayed in the hospital for a long time, but they have to take medicine for a long time when they come back, but they can't be cured, and this medicine is harmful to the human body. This is one aspect. There is also psychological counseling, and there is no hope of cure. As I said before, psychological counselors have the same things in Europe and the United States. We China people are ostracized at heart, but they don't know that he is ostracized, because he, you see, has finished consulting. He hasn't changed and he can't. In fact, his heart is rejecting these things and not accepting his cultural system. In this way, psychological counseling still can't help patients with depression. I know it used to be like this.

Moderator: So, Miss Li, what do you think can really solve the problem of depression?

Teacher Li Xingfu: I think this question is like this. If a family has a depressed person, such as a child who is depressed in middle school, first of all, our parents must understand how the child is depressed and ask about our family environment or husband-wife relationship, and whether we have correctly educated him on values. You should analyze this thoroughly. You know, he is caused by too much wrong information. If you can do this, I think this problem has been solved by more than half. Nowadays, many adolescent depression can't be cured unless it is solved from the family roots. So how did it get sick? I don't know, so we blame him, and we blame him for not studying. Blame him for not going to school; Blame him for smashing furniture; Blame him for playing with his mobile phone. This can only stay at the level of complaining, and will never solve the problem. What is serious is to send children or adults to the hospital. The same is true of hospitals. The hospital doesn't solve your faith problem. He just solves your depression and makes you stop having attacks.

In my opinion, the reason why children suffer from depression and adults suffer from depression is that there is something wrong with the belief system of his brain, that is, the beliefs it contains are incompatible with society, and he can't communicate with it, so he is depressed. Of course, there are also some emergencies, such as the sexual assault of girls, which is also a malignant emergency, but most of them are that children's brains store too many unhealthy beliefs, and these beliefs have been defined in their brains, in other words, they have been stored in the memory of cells. Our parents must first come down and send their children to class. Of course, some children don't want to, and two or three out of ten people with depression may need to be mobilized. As long as he can study and eliminate harmful memories in cells, I think it can be completely cured.

Teacher Li Xingfu: Thank you!
