The golden rooster is independent, walks continuously, kneads his hands and trains his fingers... Under the Hangzhou Zhijiang bridge, along with the BGM of "who says he can't keep the years and is full of vitality", the square dance performed by these elderly people is not very trendy, but the person leading the dance is very unusual - a 30-year-old male doctor. This set of square dance is specially used by him to publicize the prevention of Alzheimer's disease, # the post-90s taught the elderly to dance square dance to prevent Alzheimer's disease # on the microblog hot search. Prevention and treatment of Alzheimer's disease independent action of Golden Rooster in square dance The male doctor has a dual identity. His main profession is Luo Xiao, a radiologist in Hangzhou hospital. He focuses on the imaging diagnosis of Alzheimer's disease. In his spare time, he has changed into a self-Media popular science blogger "Dr. Luo Xixi". What they have in common is that he faces patients and we media audiences, 8 Chengdu is the elderly. When he came to the Zhijiang bridge, he found that the leisure life of the elderly was more colorful than he thought. Taking Hangzhou as an example, the square dance under the Zhijiang bridge could reach more than 1000 people at most. The old men and women dressed in uniform, moved neatly, talked and laughed, and were all "old drivers" in the square dance industry The old people are becoming more and more fashionable. They play taijiquan, take steps, dance square dance, play fancy tunes, and many are in line with the new era. In Huahua Internet world, the elderly group has a completely different set of Internet use habits and social behaviors. When dealing with middle-aged and elderly people over 50 every day in the Internet world, he witnessed that the Internet world is a new "pure land" , we don't need any fancy special effects here. What we need is to slow down, enlarge the subtitles, and be more encouraging and patient. What kind of experience is it for a post-90s generation to do popular science for the elderly in the Internet world? The following is his readme. Unlike the relaxed square dance, "Alzheimer's" is serious I'm Dr. Luo Xixi. I'm a radiologist in a hospital in Hangzhou. I've been focusing on Alzheimer's disease (Alzheimer's disease) since 2019 Popular science short video. At that time, our hospital was closed for a short time because of the epidemic. During the Chinese new year, I only needed to work one day a week. I had nothing to do at home. When I saw the news of looting Shuanghuanglian at the beginning of the epidemic, I checked some literature and made a video to popularize the real effect of Shuanghuanglian. The first video received a good response, and many people came to ask me relevant medical questions. Following up on the victory, I made a series of correct wearing methods of popular science masks. With more and more viewers, some people will ask me some questions related to my doctoral degree and graduation thesis, and I will also make some experience sharing videos. However, my main research direction is Alzheimer's disease (I have been engaged in the imaging diagnosis of Alzheimer's disease since the graduate student stage). There are always some family members asking me related questions (during the hospital consultation), such as "my father has Alzheimer's disease, what is the risk of my illness?" One day, I met three or four people asking the same question one after another, thinking of simply returning to my old profession and becoming a special Alzheimer's science blogger for two years. There are still many misunderstandings about Alzheimer's disease. At first, when the word "Alzheimer's disease" is mentioned, the public will play a joke. For example, when an old man starts to forget things as he gets older, his children will tease him: "are you Alzheimer's?" and take this as a joke. In fact, it is not. Alzheimer's disease is called "Alzheimer's disease" in Alzheimer's medicine , is an irreversible cognitive decline disease, which is very harmful. Common amnesia almost before death, the memory decline of the elderly is also very weak. Once suffering from Alzheimer's disease, the memory will decline in a waterfall. In the later stage, the elderly can't even maintain basic physiological functions, can't eat and excrete independently, and finally die in a mess. One case that impressed me deeply was an old professor from Zhejiang University. The professor had a genetic history in his family and his parents died of Alzheimer's disease. Alzheimer's disease was inherited from maternal lineage, and the genetic influence was very strong. Because he had to teach in his job, at first, the professor came to communicate with us when he found that he had some forgetfulness. After finding out that it was Alzheimer's disease, he was very painful, Because he also took care of his sick mother until his death, he knew what he would become in his old age, but there was nothing he could do. Later, his memory declined sharply, and he even began to steal other people's things. His character also changed to a certain extent. Sometimes he forgot to wear clothes and went out for a walk. He might not realize it until he was reminded. According to research, the higher the IQ group, the faster the IQ degradation will be after suffering from Alzheimer's disease in his later years. This contrast makes me very uncomfortable. In his later years, old age Professors have been unable to take care of themselves and lost the dignity of life. This is still very helpless. We can only hope that future medical research can help solve more insurmountable problems. Luo Xixi in the student period According to the survey, 5% of the elderly over the age of 65 will suffer from Alzheimer's disease, and there are almost 13 million people in the whole population in China, which is still a high proportion. However, we expect that there will be a big breakthrough in the next 10-15 years. Many drugs have almost reached the final phase of clinical trials, and the future is still promising. Therefore, I often recommend that middle-aged people over 50 go to the hospital for brain health screening regularly, which is not included in the routine physical examination and needs to be carried out additionally. If there is a risk of disease, drug prevention should be done early. At present, there is no radical cure for Alzheimer's disease. Drug treatment can be understood as "brake pads", which can only delay the occurrence of the disease for about 5-10 years and delay the group expected to enter Alzheimer's disease at the age of 65 to the age of 75. This effect is very good. However, if you come back to the hospital at a late stage, you have entered the acceleration period, and drug treatment is unable to recover. Luo Xixi at work, source: Chinese youth talk studio I usually make popular science videos in a more serious way. The video that teaches the elderly to dance square dance is intended to be publicized in a relaxed way, which is surprisingly out of the circle. Square dance has strong social attributes, with formation, cooperation, relatively simple action and strong sense of rhythm. The elderly can also chat and chatter, which is beneficial to the prevention of Alzheimer's disease. For the elderly, the most important thing is to encourage them to go out more, communicate with the outside world and do some light aerobic exercise. After so many years of research, the most thorny problem we have encountered is that many elderly people are unwilling to go out at all. Now some large elderly groups come to a new city to help look after their grandchildren because of their children's work. Because of their poor accent They have been taking care of their children at home since they are not familiar with their families, so it is difficult to integrate into the new environment. They still hope to be able to go out, but their grandchildren are the whole of their life. They can't live without them for a moment, and they are prone to depression over time. Insomnia, depression and anxiety are great hidden dangers in the acquired influencing factors of Alzheimer's disease. How to relieve negative emotions for the elderly deserves high attention. 80% of the audience is the elderly, and my internet environment is extremely harmonious My situation as we media is not the same as that of other bloggers - 80% of the audience of my short video account are middle-aged and elderly people over the age of 45, so the current video content is also dedicated to elderly users. The Internet environment of the elderly is different from that of the young, and their online world is very simple. Therefore, my video will also be set for the elderly - there are no fancy special effects, which is very simplified. I will explain it in the form of dialogue, slow down, enlarge the screen font, and be sure to tell them more evidence and examples. They like it Listen to how the research comes from. The elderly follow empiricism. If a younger generation comes to popularize health knowledge with them, he is likely to follow his life experience for many years. How to convince them is also a knowledge. Luo Xixi consults for the elderly In the eight years since I studied Alzheimer's disease, I have contacted more than 800 patients and families, handled tens of thousands of cases, and some have conducted long-term follow-up visits. I think people will really rejuvenate in old age, and their mentality is like children. For example, in the study, we will invite some people with early Alzheimer's disease to do memory tests, which are very simple questions, "How much is 100-7 and how much is 93-7" is very simple in the eyes of young people. However, if an old man with poor memory answers, he may have to think carefully for 2 minutes. You should wait patiently and never rush him. After he gives the answer, encourage him to "do very well!" and ask the next question. If you ask too quickly, they will be angry, depressed, and then have a resistance to do it. Just like parents keep asking children, "why can't you do this problem?" , he may have lost his homework book and ran away. There are one or two more vulnerable people who think for a long time and can't answer the question. However, the teacher thinks the question is very simple, and they will cry if they can't answer it. In the face of the elderly, there are still two strategies - more encouragement and patience. This attitude has also been extended to our popular science videos. As we media for the elderly, I will attach great importance to reply and interaction. At the end of each video, I will always say, "that's all for the video. If you have any questions, you can leave a message in the comment area below, and I will answer them as much as possible." Luo Xixi answers the doubts in the comment area Basically, I will reply to every message and establish a trust relationship with them in this way. This project is quite large. Sometimes there are nearly 2000 messages under a popular video, and I will answer as many repetitive questions as possible. I will use the commuting time every day to reply to comments within 2 hours on the subway. Old people have a sincere attitude when watching videos. They will think that I am talking to them on the other side of the screen. Therefore, they will spend a long time writing messages. Many people still use handwritten keyboards. It can be clearly seen that many words are computer recognition errors, such as "Ge" will recognize "Er" Older people still maintain various habits of letter communication on the mobile terminal. If serious handwritten comments sink into the sea and do not get a reply, they will also be very sad. On the contrary, I have to respond to their sincerity in order to make them believe what I say. Most of the audience are the elderly. The network environment is not hostile, and I basically won't encounter malicious attacks and abuse. After watching the video, the elderly are of high quality and goodwill. They will seriously express their gratitude to me in the comment area, and rarely vent their negative emotions for no reason. Like their temperament, the Internet world of the elderly has a simplicity of returning to nature 。 Internet environment faced by Luo Xixi Be a "We Media doctor" and connect the axis in 996 When I was a child, my ideal was to study medicine. When I was in college, I was more interested in studying the brain, but when I waited
