Clinically, mental illnesses are divided into two main categories: organic brain mental illnesses and functional brain mental illnesses. Functional brain mental illnesses are further divided into two main categories: severe mental illnesses and mild mental illnesses. Severe mental illnesses include: schizophrenia, depression, mania, bipolar disorder and so on. Mild mental illnesses include: anxiety disorders, social phobia, obsessive-compulsive disorder, stress disorder, adjustment disorder, neurasthenia, anorexia nervosa, hypochondriasis, somatization disorder, chronic insomnia, chronic somatoform pain disorder, somatoform dysmorphic disorder, dysthymic disorder, and so on. Mild does not equal to the condition is not serious, some mild mental illness can be so painful that the patient has a feeling of life and death; light does not equal to easy to treat, usually is more than a heavy mental illness to test the clinical level of the doctor, more need to patients and family members active cooperation and persistence. The division between mild and severe is mainly based on the cause and mechanism of the disease. Any functional brain mental illness is formed under the joint action of internal and external factors, with internal factors being the main cause of severe mental illnesses and external factors being the main cause of mild mental illnesses. The treatment of severe mental illness is based on medication to adjust the imbalance of neurotransmitters in the brain, supplemented by psychotherapy, self-adjustment and family support. In the treatment of mild mental illness, psychotherapy and positive self-adjustment by the patient are very important. Personally, I attach special importance to patients’ self-adjustment. Every time a patient comes to see me, I usually spend some time to instruct the patient on how to self-adjust. This kind of self-adjustment is of course not a random adjustment by the patient, but should follow the principles of psychiatry and psychology, combined with the characteristics of the patient’s condition, and under the guidance of specialists to go to the positive self-adjustment. This type of self-adjustment is also a kind of psychotherapy. For the treatment of various types of mild mental illnesses, the doctor guides the patient in self-adjustment, and this part of the treatment most reflects the doctor’s theoretical knowledge and clinical level. In the course of treatment, those who need to actively self-adjust are not only the patients, but also their family members, especially parents or spouses and other family members who are closely related to the patient’s condition. Self-adjustment means giving up, and giving up means suffering (Note: Reference article: Philosophy is practicing death). On the basis of the patient’s positive self-adjustment, together with medication, it can be twice as effective, and medication can create conditions for the patient’s self-adjustment. For a variety of mild mental illness, if only with drug treatment, is bound to be a large amount of drugs, long course of treatment, easy to form a drug dependence, but increase the difficulty of treatment in the future, resulting in the condition of the repetitive, prolonged not cured. Guangdong, a super-large tertiary hospital has a professor of neurology, looking for him to see patients is also super, once he told me: “I see a lot of patients are your psychiatric department, I see half a day clinic, to see 50 patients with depression.” Many patients with anxiety disorders, because of physical symptoms such as headache and insomnia, do not first come to see our psychiatrist, but first go to see a neurologist (Note: also see other internal and external departments, because the physical symptoms of anxiety disorders can be spread throughout the body’s various systems and organs, Yu Jinlong), and the neurologist is usually not able to distinguish between anxiety disorders and depression, misdiagnose anxiety disorders as depression, and misdiagnose mild psychiatric disorders as severe mental disorders, and prescribe medication to treat them. They misdiagnose anxiety disorders as depression, misdiagnose mild mental illnesses as severe mental illnesses, and prescribe drugs to treat them (mainly antidepressants, tranquilizers, and sometimes antipsychotics such as olanzapine; at present, only a small proportion of the antidepressants prescribed by general hospitals are prescribed by psychiatrists, and most of them are prescribed by doctors in other departments, especially neurologists), without instructing patients on how to help themselves. However, they do not instruct their patients on how to self-adjust; they have neither the time nor the knowledge and experience to do so. Over time, many neurologists are followed by a large number of psychiatric patients, mainly with mild mental illnesses such as anxiety disorders. When they finally come to see our psychiatrists, some of them have been in treatment for several years or even longer, and many of them are already drug dependent or addicted, which makes the complexity of their illnesses and the difficulty of treating them increased.
