The first is biological factors.
Depression is generally divided into endogenous and exogenous categories. Endogenous depression is often caused by internal factors of the body and has obvious biological characteristics. This intrinsic factor is actually a gene, which is often obtained through heredity. It is the root cause of the imbalance of three neurotransmitters in the brain: serotonin, norepinephrine and dopamine.
In real life, it is often observed that there are other mental patients in the immediate or collateral relatives of a depressive patient. This shows that the heredity of this family is obvious.
Psychiatrists in a hospital believe that about 5% to 10% of the world's population has this genetic gene and is prone to depression. Others believe that genetic factors play an important role in the pathogenesis of depression.
There is such a data-the heritability of depression reaches 80%. The so-called heritability means that if you carry the disease-causing gene, the possibility of getting sick will reach 80%. But so far, the internal relationship between genetic factors and depression can not be explained scientifically. Even with advanced instruments, it is impossible to observe the process of chemical changes in the brain. The intrinsic punisher of human nature.
The theory of genetic factors has not been scientifically verified, but personality factors can be considered to play a more important role. Different people have different personality characteristics. Relatively speaking, people who are simple, sensitive, self-respecting, stubborn, aggressive, perfectionist and used to self-denial, guilt, self-blame, introspection and self-blame are prone to depression.
Why? There is no scientific explanation. Professor Rong's point of view is that all the above characters are easy to make emotions in a state of tension, and emotions are a bridge from psychology to physiology. In the long run, nervous mood will destroy the function of secreting neurotransmitters in the brain, and the seeds of depression will come from this.
Psychology believes that self-reproach and self-reproach are the most likely to destroy people's psychological structure. It constitutes an internal punishment mechanism to condemn and sanction itself. Depression, inferiority, low self-evaluation and low vitality of patients with depression mostly come from this.
Zhang Jin, the author of Flowers, has also carefully traced his cause. His final conclusion is that it may be related to the environment in which he lived in his childhood and adolescence. Before he was born, his father was sent to work in the rural areas of northern Jiangsu because he was a rightist. He was persecuted and bullied outside and came home in a bad mood. Because of his sensitive nature, he felt beyond his age about the harsh living environment since he was a child, learned to be rational, patient and restrained, and resisted external aggression through restraint.
However, the inner rebellion stimulated anger to grow quietly in his heart. As a teenager, he actually faced his own world with a marginal uncooperative attitude. After being admitted to the university, he has been trying to overcome the tension between himself and reality for many years and find a way to reconcile himself with the outside world. He once thought he was very successful, but the shadow of childhood and adolescence will become a subconscious conditioned emotional response, rooted in the depths of human nature.
Then there are environmental stress factors.
For example, work pressure, life pressure, interpersonal pressure, etc., they should also take emotions as a bridge. Different roads lead to the same goal, acting on neurotransmitters.
However, Professor Rong believes that unilateral stress is not enough to cause depression. As mentioned above, most people with depression will be introspective, restrained and even self-sacrificing. If the pressure comes from only one side, they can also solve it through compromise. However, if a variety of pressures from different directions swarm in and these pressures are mutually exclusive, it is neither compromise nor perfection, and depression will enter the room at this time.
Two days ago, a visitor came to Professor Rong to talk about her mother's illness. She said that her mother's personality was simple and cheerful, her life was happy, and her work was smooth. She couldn't find any reason to get sick, only an accident. Last year, my grandparents moved from her uncle's house to hers. The two old people were selfish, eccentric, demanding and inconsiderate. As a result, the quiet and orderly life at home was disrupted. In her opinion, her mother suffers from depression because she can't cope with the pressure of her parents.
From the girl's endless narration, Professor Rong heard her and her father's antipathy to grandparents. Professor Rong hesitated, but decided to tell the truth about the fact that he unilaterally attributed the cause to two old people. Professor Rong said that even if the two old people are really selfish, picky, unreasonable and greedy for enjoyment, they may not be able to crush her mother. After all, they are father and daughter. Mother and daughter love each other. The question is: will your mother bear more pressure from different directions? For example, is your uncle stressed? Your mother hasn't done her duty of support for many years, and now her grandparents are not satisfied. How does she face her brother? Will your complaints with your father also be a source of stress for your mother? Three aspects are his relatives. What should she do? These three pressures are intertwined, and she can only endure self-sacrifice. However, if we compromise, it will be impossible to be perfect. Her inner anxiety, self-blame, self-blame and helplessness may converge into a torrent and wash away her spiritual dam.
Professor Rong said, "If you love your mother, you should stop complaining about your grandparents and relieve your stress."
The last factor is traumatic emergencies.
For example, out of school, unemployment, lovelorn, death of relatives, failure of stock trading and so on. However, emergencies are only stimulating factors, not real reasons. Depression is deeply rooted in your humanity. Even without this traumatic event, there will be other events. The only difference is the timing of the outbreak. Of course, with luck, it will disappear after ten or eight years.
