"Elderly people with back of ear are more likely to suffer from Alzheimer's disease?" A message on social media has drawn more attention to the plight of the elderly after hearing loss. From unclear to incomprehensible, the communication between the deaf elderly and others becomes less and less, which is also easy to cause psychological problems. Some ear problems are not caused by old age, but may recover. After ear back symptoms, the elderly should not "judge by themselves" but go to the hospital in time. Every time I see Grandma, I feel a little distressed. Every weekend, Wu Chen goes to see her 91 year old grandma. The old man lives with the nanny and has no worries about living, but because of poor health, he seldom goes out and has no social activities, so he is inevitably lonely. Every time my grandson comes to my house, the old man is very happy and always pulls Wu Chen to ask questions. As a junior, Wu Chen certainly understands the old man's mood of wanting to talk to someone, and he is also willing to tell the old man about his recent experience. However, Wu Chen always struggles with his communication with Grandma. Compared with legs and eyes, the old man's physical function that dropped most was hearing. No matter what Wu Chen said, Grandma always interrupted. In order for the old man to understand what he was talking about, Wu Chen even used "sign language", but the effect was still limited. "Have you not quarreled with Xiaoyu (Wu Chen's wife) recently?" "No, Grandma, we are fine!" "Have you quarreled? You have to yield to her!" What made Wu Chen helpless was that Grandma often asked and answered herself, and her answers were always negative. The problem of hearing loss in the elderly actually existed several years ago. At that time, the family accompanied the old man to the hospital to be equipped with a hearing aid. At first, the old man's hearing improved, but after a period of time, the hearing aid did not work. At this time, she always refused to let the old man go to the hospital on the grounds of being troublesome. After hearing loss, the elderly can carry out much less daily activities. In the past, Grandma could also answer the greeting calls from relatives and friends on New Year's Day, and chat with peers in her hometown in hometown dialect. But in the past two years, she could not connect to the phone. Neither the nanny nor Wu Chen can understand Grandma's native dialect, so they can't tell the story if they want to. "I really feel sorry for the old man's living condition, but I can't help it." What Wu Chen can do is to develop the ability of "going in one ear and going out the other". I still talked with Grandma when I got home, but I tried not to take what the old man said to heart. Why do hearing aids not work for the elderly? Li Changqing, director of the otorhinolaryngology department of the Beijing Geriatric Hospital, believes that this may be related to improper fitting at that time. "When we equip hearing aids for patients, we need to adjust the audiogram one frequency point by one, so that the device can be fully adapted to the patient's ears, and the effect will be good." In this process, it is necessary for the elderly to fully communicate with the optometrist, because only the elderly know their subjective feelings about the sound. However, some elderly people may be more resistant to seeing a doctor and get confused when communicating. Finally, even with hearing aids, the effect is not very good. "In addition to hearing aids, another way to improve hearing is to make cochlear implants." Compared with the former, the process of cochlear implantation is more complicated, requiring surgery, and the elderly are more difficult to accept. "We have treated some elderly patients
