How common is schizophrenia? What causes schizophrenia

According to statistics, in many places, 0.5% to 1% of people will suffer from schizophrenia at some point in their lives. In large cities, the ratio will be higher. Men and women are at the same risk. It can be seen that schizophrenia is a very common mental disorder. Some people will ask: Why do you get schizophrenia? What causes the onset of schizophrenia? At present, although specific genes and chromosomes have not been identified, there is strong evidence that the disease is caused by genetic factors Impact. Predisposition to schizophrenia may be inherited rather than the disease itself. In identical twins, if one has schizophrenia, the probability of the other being schizophrenic is only 40% to 50%, because the genes of identical twins are the same; there is also sufficient evidence that the cause is not only a genetic abnormality , this is known as the "stress-quality" model or "two-hit" theory: environmental factors increase genetic susceptibility. But there appears to be an increased risk of developing progressive schizophrenia in a variable environment, increasing the likelihood of multiple predisposing factors. These environments are obstetric syndromes and perinatal complications that can lead to hypoxia affecting the brain of the child and viral infections in the mother during pregnancy. The increased risk was also associated with being born in late winter and early spring, possibly because of the increased prevalence of colds and flu during this time period. A study has found that a higher risk of schizophrenia is linked to paternal age, possibly because of random mutations in reproductive genes. The following is a specific analysis: 01 Genetic factors Schizophrenia cannot appear for no reason. One of the causes of schizophrenia is heredity. Genetic factors play an important role in the pathogenesis of schizophrenia, which is a more positive conclusion. In a classic clinical twin study, fraternal twins have a three-fold lower morbidity rate than identical twins, and identical twins raised separately have the same prevalence. Moreover, the closer the blood relationship is, the higher the prevalence rate. On the contrary, the genetic risk is smaller. It should be noted that if the family has schizophrenia, it is indeed easier than the average person to get the disease, but it does not mean that you will definitely get schizophrenia. 02 Personality reasons Some scholars who study mental illness have proposed that a person's personality characteristics are related to mental illness to a certain extent. People with different personalities have different probability of suffering from mental illness. People with schizophrenia, such as withdrawn, indifferent, indifferent to communication, excessive sensitivity, lack of interest, etc., are prone to schizophrenia; while those with self-centered, suggestive, good self-expression, and irritable personality are prone to hysteria. These are all factors that contribute to the etiology of psychosis. Personality is an important internal factor in the onset of schizophrenia, and it is relatively difficult to treat, and the risk of recurrence is also relatively large, so special attention should be paid. 03 Somatic diseases and self-metabolic factors This is one of the causes of mental illness. Certain somatic diseases, such as infections, trauma, metabolism, endocrine, nutritional deficiencies and other diseases, can lead to brain dysfunction and cause mental disorders. The body in bad state, such as fatigue, menstrual period, pregnancy and puerperium, etc., can also induce the occurrence of mental illness, such as menstrual cycle mental disorder. 04 Mental stimulation Mental stimulation may also be one of the reasons for the onset of schizophrenia. For example: bereavement, lost love, work frustration, etc., mental stimulation is the most common root cause of schizophrenia. Whether it is a pleasant benign stimulus or a painful malignant stimulus, exceeding a certain limit will affect people's psychology. So don't underestimate the role of mental stimulation in the pathogenesis of schizophrenia. Schizophrenia is a mental disorder with a very high recurrence rate and disability rate. We know what causes schizophrenia, and we must try our best to avoid the disease in our daily life. At the same time, if you find a disease, please actively treat it, otherwise the disease will be delayed, which will cause a huge burden on the patient's own life, work and study, as well as the family and society.
