1.Not long ago, experts pointed out that “Yinzhi” (negative AIDS, no infected person at present, only that there are AIDS symptoms) is a kind of hysteria performance, is this statement correct? What is hysteria? What are the manifestations of hysteria? As far as the current national and international diagnostic criteria for mental/psychological disorders are concerned, I am afraid that it is difficult to give a diagnosis of dysthymia to most individuals with “negative AIDS”. Hysteria is a mental disorder caused by mental factors, such as life events, internal conflicts, suggestion or self-referral, acting on the susceptible individual, mainly manifested as mental abnormalities (hysterical mental disorder), physical abnormalities (hysterical somatic disorder) and some special manifestations. paralysis, inability to walk, muteness, loss of voice, sensory deficits, sensory abnormalities, blindness, deafness, selective deafness, etc. The specific manifestations are varied, and almost all the symptoms of other ordinary clinical patients can appear in hysterical patients, but the fundamental point is that for hysterical patients, all symptoms lack the support of objective findings, that is, the symptoms lack the basis of organic lesions. 2, not only Yinzhi events, similar to Islamophobia, doomsday phobia, etc. From a psychological point of view, what is the reaction of a disease and what kind of consequences does it bring? In fact, from a psychological point of view, most of these phenomena such as Islamophobia and doomsday phobia are not considered a disease, but more of a reaction to some psychological phenomena of the public, such as herd mentality and insecurity, and the same is true of the salt rush that occurred in China some time ago. There are good aspects and bad aspects of herd mentality. For example, if there are 10 people waiting for the red light at the intersection, if everyone does not run the red light, even if one wants to run, he will feel the pressure. On the contrary, if there are 9 people who run the red light, it will become a pressure to comply with the one who will generally follow. For the herd mentality, it should be guided or controlled according to the actual situation, especially some catastrophic rumors (such as earthquakes, some major public events), which may cause great panic in the public or even lead to catastrophic consequences if not controlled in time. On the other hand, for individuals, when receiving a message, they should pay attention to keep their own independent thinking, and refrain from following the clouds and receiving the information uncritically in its entirety. 3, the above-mentioned are negative events, there are some positive events, such as hearing people talk about health topics, they feel good about health, will actively health, such a psychological implication, for the establishment of a positive health mindset what good? Such a herd mentality is undoubtedly good for improving the health literacy of the public, but there is one thing, no matter what the situation is, it is necessary to maintain the habit of independent thinking, not to follow the clouds. Now there are many health experts, the level is uneven, and some are even liars, if individuals do not have independent thinking and some scientific literacy, and will appear “raw loach cure” joke to come. On the other hand, from a psychological point of view, individuals should maintain a moderate level of attention to the health of the self, excessive attention to self-health can even lead to some physical and psychological diseases. For example, many patients with functional diseases (functional gastrointestinal disease, cardiac neurosis), neurological disorders (somatoform autonomic disorders, somatoform pain disorders, hypochondria) show the psychological phenomenon of excessive concern for the health of the self. 4. Is there a psychological name for an event or symptom like the above, or a word of mouth from people around you that makes you feel like you have the same symptom or fear? Please describe this disorder in detail? Is there any way to alleviate this disorder or manifestation? This phenomenon is called suggestion in psychology, and the psychological phenomenon of suggestion is widely used in psychotherapy, as well as in some folk health techniques (such as qigong), and even some charlatanism. Strictly speaking, every individual has suggestibility, but the level of suggestibility varies among individuals. Generally speaking, individuals with more comprehensive understanding of certain events or phenomena, more independent personalities and more autonomous thinking habits have relatively low suggestibility. 5.What kind of psychological disorder do you think “yinzhi” should be? Do you have any similar cases among the cases you have seen? Can you briefly describe them? As far as “Yinzhi” is concerned, professionals generally believe that it is a special kind of phobia – AIDS phobia. There are several possibilities for the symptoms of individuals with “Yinzhi”: (1) These individuals with “Yinzhi” were already suffering from other diseases prior to the high-risk HIV behavior, but these patients did not notice it, just after they had the high-risk behavior, they were too concerned about their own health and went to the hospital. (1) These “yinzhi” individuals had other diseases before they had HIV, but they didn’t notice them. Because the symptoms during the onset of AIDS are mainly various symptoms based on the reduced or absent immune function, and there are many factors other than HIV that can cause the immune function of an individual to be affected. (2) From a psychological point of view: at least several adverse emotions can be seen in individuals with “yinzhi”: fear, anxiety, suspicion, depression. Psychological factors can cause some somatic reactions, including physiological and biochemical reactions, such as increased blood pressure, increased blood sugar, and changes in immune levels in individuals under stressful conditions. (3) Lastly, science is endless, and as far as the current level of medical science is concerned, it cannot be completely ruled out that the individual with “Yinzhi” is suffering from another disease condition, but it is generally not an infection with a new variant of HIV, because in terms of the course of AIDS, it is impossible to develop symptoms within such a short period of time after a high-risk behavior (even if one is infected with the virus after a high-risk behavior). It is unlikely that symptoms will appear within such a short period of time. We have not yet seen any “negative” cases (i.e., some symptoms or abnormal laboratory tests) in our clinical psychology department, but we have seen patients with AIDS phobia, some of whom have had high-risk HIV behaviors and some of whom have never had high-risk behaviors. They show a great fear of contracting AIDS, and repeated negative HIV tests still do not release them (one patient even had to be tested for HIV once a week). At the psychological level, they show emotions such as fear, anxiety, suspicion and depression as well as behavioral withdrawal and social avoidance, which seriously affect the patients’ social functioning and quality of life.
