In China, people are often cursed with mental illness or neurosis, describing people who talk nonsense and behave oddly. In fact, it is incorrect to curse people with neurological disease, which refers to diseases in which the tissues of the nervous system are diseased or dysfunctional, the most familiar neurological disease is cerebral infarction, commonly known as “stroke”. So is it right to use mental illness to curse people? From a scientific point of view, this is also incorrect. Psychosis refers to a group of neurological disorders that are characterized by disorders of behavior and mental activity. Since the concept of disorders of behavior and mental activity encompasses a wide range of content, the category encompassed by psychiatric disorders is actually very broad. There is also a buzzword called mental illness, and there is a great deal of conceptual overlap between mental illness and psychiatric disorders. There is no such concept as mental illness in the medical field, but because the name mental illness has been stigmatized, all sometimes call a portion of mental illness a mental illness, but there is no authoritative definition of exactly which mental illnesses count as mental illnesses. The diagnosis of any disease is made according to certain criteria, and mental illness is no exception. At present, there are two main systems for the diagnosis of mental illness internationally, one is the ICD system (International Classification of Diseases) led by the World Health Organization organization, which contains the diagnostic names and diagnostic criteria for almost all known human diseases, including those on mental illness, and the current one used is the 10th edition ( ICD-10), ICD- 10 was endorsed at the 43rd World Health Assembly in May 1990 and has been used in WHO member countries since 1994, and the majority of the world’s national health care systems basically use the ICD system for clinical diagnosis. The other is the Diagnostic and Statistical Manual of Mental Disorders (DSM) system developed by the American Psychiatric Association, which is widely used clinically in the fourth edition of the DSM, and the fifth edition of the DSM was also developed in 2012, but has not yet been used on a large scale. The DSM system and the ICD system also have a high degree of consistency in diagnosis. In order to reflect Chinese characteristics, China has also developed a CCMD system (Chinese Classification and Diagnosis of Mental Disorders) with reference to the standards of ICD and DSM, the latest version of which is CCMD-3. With the increasingly close medical exchanges between China and foreign countries, more and more doctors in China have stopped using the CCMD3 and adopted the ICD system for clinical diagnosis in recent years. the Mental Health Law promulgated in 2013 officially requires that China’s classification and diagnostic criteria for mental disorders be based on internationally accepted medical standards, so the domestic psychiatric community has started to fully adopt the ICD system for clinical diagnosis. However, the DSM system is still mainly used in the field of scientific research. In both the ICD and DSM systems, we can see that the classification of mental disorders includes a similar classification of mental disorders. The following is an example of the ICD-10 system, which is the most commonly used system for clinical diagnosis. The ICD system classifies human mental disorders into ten major categories, each of which is named and numbered as follows. F00-F09 Organic, including symptomatic mental disorders F10-F19 Mental and behavioral disorders due to the use of psychoactive substances F20-F29 Schizophrenia, schizotypal disorders, and delusional disorders F30-F39 Mood (affective) psychoses F40-F48 Neurotic, stress-related, and somatic forms of disorders F50-F59 Behavioral syndromes related to physical disorders and somatic factors F60-F69 Adult personality and behavior disorders F70-F79 Mental retardation F80-F89 Mental developmental disorders F90-F98 Behavioral and emotional disorders that usually begin in childhood and adolescence The ICD-10 diagnostic criteria cover hundreds of psychiatric disorders, including Alzheimer’s disease, vascular dementia, mental retardation, schizophrenia, and other disorders that severely affect the human mind. developmental delay, schizophrenia, and the well-known depression, as well as insomnia, premature ejaculation, and non-organic vaginal spasms, which are not considered psychiatric disorders by the general population, including many non-psychiatrists in our country. If understood simply, in the spectrum of human illnesses, all but somatic illnesses can be considered mental illnesses. The term psychiatric disorder, which is used daily to scold people, should be understood connotationally to include organic mental disorders, mental and behavioral disorders due to psychoactive substances, schizophrenia, some mental (affective) psychiatric disorders, some adult personality disorders and behavioral disorders. The depression that Cui suffers from belongs to one of the broad categories of mental (affective) psychiatric disorders. According to the criteria of ICD-10, this major category includes 10 subcategories of manic episode, bipolar disorder, depressive episode, recurrent depressive disorder, persistent mood (affective) disorder, other mood (affective) disorder, and unspecified mood (affective) disorder, and each subcategory contains several specific psychiatric disorders. As for Cui’s depression, it is not easy to determine the specific type of depression because the medical history is not detailed. Because of the wide range of mental illnesses, the probability of humans getting a mental illness is very high. According to the World Health Organization, the lifetime prevalence of various mental illnesses worldwide is one in four, which means that one in four people has suffered from mental illness, and the incidence rate in China is as high as 17.5%. This series of data has reached the point of “appalling” in the eyes of some ordinary people and even many doctors, because these figures are obviously not in line with their “common sense”, which also shows that our “common sense This also shows that our “common sense” is not reliable. This is due to a number of reasons, the most important of which is the lack of attention to mental illness in our medical education. Since mental illness is a relatively new discipline, it started even later in China, and community mental health work in China almost stopped during the Cultural Revolution due to political reasons. Medical education in China has always been based on the biomedical model, and although the biopsychosocial medical model of education is called for, the emphasis on psychological and social factors in the medical education process is far from adequate due to the lack of faculty. Psychiatry and medical psychology have not been the main courses in medical schools in China, and compared with other main medical courses, the study courses of psychiatry are very inadequate, and the understanding of psychiatric diseases is limited in the clinical internship stage because almost all of them do not rotate through psychiatry. Most hospitals in China also do not offer psychiatry, and most of them are staffed by neurologists, who have limited knowledge of psychiatric disorders because they have not received specialized training in psychiatry. Because most physicians do not understand mental illness, there is even less publicity about mental illness. As a result, the general public in society has no knowledge of mental illness, and many people with mental illnesses go untreated for a long time, or deny having the illness, or turn to God or Buddha. Mental patients and even psychiatrists are stigmatized, which cannot be said to be a major failure of contemporary medical education in China.
