Before recognizing the above issues, we first recognize the etiology of mental impact, there are three specific categories: 1, biological factors: is the brain itself, is the material brain cells have lesions and dysfunction. Such as genetic influence, brain damage and degeneration, etc. 2, social factors: is the presence of adverse mental stimulation and mental stress. Brain because of mental stimulation and mental stress, causing thinking, emotional and behavioral reactions, but also caused by the dysfunction of the plant nervous, endocrine and immune function. 3, psychological factors: is the process of the patient’s own mental activities have problems. Such as the shadow of trauma in early life, as well as the sensitivity and immaturity cognitive problems left behind. Current cognitive problems, cognitive patterns, behavioral habits, patterns of psychological defense mechanisms, incongruence between motivational needs and oneself, insufficient social life skills, insufficient emotional intelligence and character defects, etc. According to clinical etiology, we can classify psychiatric symptoms into three categories: 1. Psychiatric symptoms of biological etiology: The etiology of these psychiatric symptoms is mainly related to biological etiology, which is the presence of lesions in brain cells. This type of mental disorder can have obvious mental abnormalities, and the condition is relatively serious. Psychiatric disorders have a significant impact on social life, study and work. The treatment is mainly based on psychotropic drug treatment. 2.Psychiatric symptoms of social etiology: The etiology of these psychiatric symptoms is mainly the reaction of human brain to social stimuli. There are reactive symptoms of thinking, emotion and behavior. There are also psychosomatic reactive symptoms on the vegetative, endocrine and immune level. Treatment is mainly based on psychotherapy, supplemented by medication. 3.Psychogenic psychiatric symptoms: The cause of these psychiatric symptoms is a problem with one’s own mental activity process. Generally, these psychiatric symptoms do not have obvious mental abnormalities and the disease is relatively mild. The disease has no obvious impact on social life, study and work. Treatment is mainly based on psychotherapy, supplemented by medication. Special attention is paid to the fact that psychotropic drugs cannot change social factors, nor can they change psychological factors. That is, no medication can change mental stimulation and mental stress. No drugs can change cognitive concepts and behavioral habits, etc. Therefore, it is important to distinguish the nature of your symptoms in treatment. You cannot treat psychological disorders by thinking in the way of visiting a somatic disease and just taking medication. Psychological disorders have been clearly emphasized in medical monographs as being psychotherapy-based, not medication-based.
