A, from the social and psychological point of view of the recognition 1, the brain’s internal long-term repression of negative emotions Patients suffering from panic disorder, basically can be found to have long-term emotional repression, or evidence of greater mental stress. Commonly there are in-law relationship, family relationship, work pressure, economic pressure and other aspects. 2, repressed negative emotional energy in the brain suddenly released, symptoms appear Long-term repression of negative emotions, is a huge mental energy. This energy will not disappear on its own and will be repressed inside the subconscious. When the negative emotion becomes too great, it will be suddenly released. If the emergence of mental symptoms is in the emotional center, it is the intense fear experienced by the patient with panic disorder, a primary emotion for which no corresponding cause can be detected. If the arising is a somatic symptom, it can be said to be a somatized expression of emotions, that is, negative emotions affecting the autonomic and sensory nerve centers, expressed on these centers. The root cause of the somatic symptoms is a dysregulation of these nerve centers, which is expressed in the somatic organs, which are not organically altered, i.e., there is no corresponding disease in the body. Therefore, patients with panic disorder often consult internal medicine first with somatic symptoms, and then refer to psychology for consultation. 3, when the symptoms appear, the mind misjudged the security problem Panic disorder fear symptoms with a variety of somatic symptoms appear, most patients do not know it is only a functional disorder, no danger. So it is easy to misjudge the problem of security and aggravate the panic disorder attack. From the social and psychological perspective of understanding, the idea in treatment is to advocate psychotherapy as the main focus. Second, the understanding from the biological perspective The psychiatrist’s vision is often the biological perspective. It is the belief that it is the patient’s brain cells are sick, how sick is currently, the reason is unclear, modern science and technology and instruments are not yet able to check the lesions of brain cells. From the biological perspective of understanding, the idea in treatment is to advocate drug therapy. However, if the cause of the disease is unclear, medication can only be used empirically.
