Many people do not understand this problem. Because in their opinion, “heart disease needs heart medicine”. This so-called “heart medicine” of course does not refer to the chemical pills or capsules, but refers to a kind of language (including comfort, explanation, explanation, education, etc.) to achieve a change of mind or emotions. It is difficult for people to relate emotional feelings such as one’s sadness, anger or anxiety to these chemical powders, neither understanding nor believing that chemicals can change one’s mental state. There are many reasons for this misconception, and if we want to eliminate this misconception at the root, we must do an analysis of the so-called “heart disease”. The so-called “heart” refers to our mental activities, including a person’s cognitive, emotional and volitional behavior. The “disease” of the “heart” refers to abnormalities in a person’s thinking, feelings and behavior. First of all, we have to understand that the so-called “heart” is based on the brain as the material basis, without the brain, without tens of billions of brain cells, there would be no so-called “heart”. Have you ever seen a person who has no brain but still speaks, thinks, and has joy and sorrow? But we have seen people with highly damaged brain cells (e.g., severe Alzheimer’s) who have lost almost all the basic attributes of the human psyche, so that they cannot remember what they have just said, cannot tie their shoes, cannot open the door with the key, let alone have subtle emotional communication. Therefore, what we call “mind” is not an abstract, invisible and ubiquitous thing, but without the brain, the so-called “mind” is nothing. Because it does not exist (religious beliefs and the belief in the immortality of the soul are another matter). So, what is the so-called “material basis” of the brain? The brain has tens or even hundreds of billions of nerve cells, and within the cells there are constantly subtle changes in the synthesis, release, secretion, re-storage, degradation and removal of many chemicals (for the brain, these changes can be dramatic). Any small change in our thoughts, emotions, and physiology cannot be separated from the changes in these chemicals, but they are invisible to our naked eyes. Therefore, the so-called “mental activity” is based on the changes of these chemicals in the brain. Of course, the problem is more complicated when we look deeper, but at least one thing is certain: our thoughts and emotions are not something (mysterious) that arise out of nowhere and are outside of our body and brain. In this way, the so-called “disease of the mind” is actually a “disease of the brain”, which is simply understood to be the result of an imbalance of brain chemicals. Therefore, the conclusion becomes clear: drugs can change a person’s psychology, that is, sometimes we can correct psychological pathologies through drugs. For example, we now know that depression is the result of a deficiency of a chemical in the brain called pentothal, and that psychotic hallucinations and delusions are associated with an overproduction of a chemical called dopamine. We also know that a chemical called norepinephrine improves alertness and attention, while acetylcholine deficiency and glutamate overproduction may be associated with memory impairment. Of course, the issue is much more complex than that, because there are a large number of chemicals involved in human mental activity in addition to these so-called central neurotransmitters. Having said that, some people may still be confused: if psychological problems have a material basis, why can psychotherapy (professionally known as “mind medicine”) make a difference? In other words, why can “mind medicine” change chemicals? Is this possible? It is entirely possible. Psychotherapy relies on language, and language is a signal stimulus that can produce chemical changes in the brain. Haven’t you ever experienced the pain of “breaking your heart” because of sadness? Thoughts and emotions change our bodies (including our brains), and this change can be both good and bad. The good side is that through mental redirection, cognitive change, and emotional catharsis, certain chemical imbalances in our brain are corrected again. Therefore, we can say with certainty that medications are just as therapeutic as psychological detoxification. Only, drugs change one’s emotions and thoughts by altering chemicals, while psychotherapy works with brain chemicals by changing one’s thoughts and emotions, with the result that subtle material changes occur in our brain, and these changes are reflected psychologically in changes in our thinking, emotions, actions and personality. However, for more serious psychological (or mental) problems, chemicals (drugs) undoubtedly have a faster and stronger therapeutic effect than psychotherapy (heart medicine) can simply do, and likewise, there are some problems where psychotherapy can make a big difference, but drugs are out of reach. Now you may be clear, some psychological problems, still need drugs to solve, sometimes, they solve faster and better.
