Mental illness is a group of serious mental illnesses with complex etiology, often caused by a combination of multiple factors, and generally requires long-term treatment. In the process of daily diagnosis and treatment, many ordinary people have many misconceptions about mental illness, so it is important to eliminate these misconceptions in order to improve the level of understanding of mental health and scientific quality of the public, and enhance the awareness of prevention, treatment and rehabilitation. One of the misconceptions is that all people who suffer from mental illnesses do so because they have been stimulated. In fact, many mental illnesses develop when mental stimulation is not obvious, some are not at all, some mental stimulation can only be considered a trigger, the underlying cause is the patient’s own reasons, for example, some young students are criticized by teachers, after failing exams, schizophrenia, bipolar disorder, it can not be said that the illness is caused by the teacher’s criticism. Myth No. 2 All people who suffer from mental illness are caused by being careful, introverted and uncommunicative. Personality is one of the factors that predispose to certain mental disorders, but it is not an important or the only factor. Personality is closely related to genetic quality, and people with poor personality have a significantly increased risk of disease. Myth #3 Psychosis is a genetic disorder. Modern genetic studies have concluded that the inheritance of mental illness is a polygenic inheritance, and there is no necessary link between genes and the onset of the disease, but the risk or chance of the disease is inherited from parents to their children. Myth No. 4: After a mental illness is cured, you can stop taking medication. With the development of science and technology, the types and dosage forms of drugs are constantly updated, bringing great convenience to patients in taking medication, such as daily-acting (once a day), weekly-acting (once a week or once every two weeks), long-acting (once every four weeks), tablets, orally disintegrating tablets, drops, injections , liquid, etc. Myth No. 5 Anti-psychotic drugs are addictive, and dependence can form after a long time of taking them. Various antipsychotic drugs and psychotropic drugs are not a concept at all, and the former will not become addictive when taken for a long time. Psychotropic drugs, including morphine, dulcolax and other painkillers, are addictive and cannot be used for a long time. Some sedative-hypnotic drugs such as Valium have very low addictive properties and will not cause any problems as long as they are taken under the guidance of a physician. Myth number six is that drugs are three times more toxic, as are antipsychotic drugs, and long-term use will eat the brain, eat stupid. The new antipsychotic drugs that are widely used in clinical practice today are approved by the government for clinical use only after rigorous animal and human trials and then phase III clinical trials have been conducted to prove their safety and effectiveness. A large number of clinical studies have proved that new antipsychotic drugs have fewer toxic side effects and do not cause substantial damage to the brain and various organs of the body. Myth No. 7: Mental illness is a psychological disorder treated mainly by psychological guidance, and medication is not important. A large number of studies have confirmed that most psychiatric disorders have functional and structural changes in the brain and require medication or physical therapy to improve the structure and function. Except for some psychological disorders closely related to psychological factors that can be solved by psychotherapy alone, all others require medication, physical therapy, psychotherapy or a combination of the three. Myth #8 Mental illness can be cured surgically. There is no conclusive evidence that brain surgery can cure mental illness or replace medication; surgery itself has significant risks and sequelae. Surgery is strictly forbidden except for a very small number of patients who are suffering from self-inflicted injuries, suicide, assault, or injury to others, and for whom medication is completely ineffective. Myth No. 9 Chinese medicine is more effective than Western medicine in treating mental illnesses, has no side effects, and treats both the symptoms and the root cause. Chinese traditional medicine in many chronic diseases does have his unique, but in the field of mental illness Chinese medicine is dwarfed by the efficacy of Western medicine, many patients listen to small advertising lull, superstitious Chinese medicine, eat tonics, not only a waste of money, but also delayed the disease. The nine misconceptions mentioned above are widespread in the general public, especially among patients themselves and their families exist for patient treatment, recovery, and healing can play a negative role.
