66-year-old Wang Weizhong is a well-known producer in the film and television industry. He recently launched his latest stage play “A Happy Event in a Village”. In an interview, he revealed that he has a personal relationship with the famous director Hou Hsiao-hsien, who was recently rumored to be suffering from Alzheimer’s disease. If he had known about his health Condition, unfortunately no contact in recent years. He also revealed that he was in poor health. He said that he couldn’t hear two high-pitched sounds in his right ear. He would be criticized for having a bad ear. He couldn’t even hear his wife’s thoughts, which made her angry. Doctors remind that hearing loss is a common factor causing dementia in many elderly people in recent years. If you often cannot hear others speaking, active treatment is required.
Hearing loss is more than just “difficulty hearing” and may lead to dementia

When interviewed, Wang Weizhong said that his memory is still very good, but he cannot hear the two high-pitched sounds in his right ear because he did not hear his wife when she muttered, which made her even more angry. Although it sounds funny, Hou Siren, an otolaryngologist at Dalin Tzu Chi Hospital in Chiayi, reminds us that dementia is what modern people are most afraid of. According to a study conducted by the University of London published in the authoritative international journal “The Lancet” , about 35% of dementia cases are caused by a combination of 9 risk factors including hearing impairment, so do not ignore hearing loss.
High audio frequencies are particularly susceptible to damage
Hou Siren said that Wang Weizhong mentioned that he had two high-frequency impairments. In fact, the structure of the cochlea in the ear, which controls hearing, determines human hearing loss. The most common cause is damage to high-frequency audio. He explained that the hair cells of the cochlea are three-dimensional spirals. There are hair cells distributed in different parts of the cochlea that can sense different frequencies. The high-frequency hair cells are distributed in the outermost ring, so whether you listen to headphones too loudly, Noise damage, cold virus infection, etc., will stimulate the outermost ring of high-frequency hair cells, so high-frequency hair cells are most susceptible to damage.

If only the high frequencies are degraded, but the mid- and low-frequency hearing is normal, there will usually be no problems with communication between people in this situation. Hou Siren said that as the hearing loss worsens, if the high-frequency hearing deteriorates to the point where the sound must be louder than 80 decibels to be heard, and the patient’s hearing of sounds lower than 80 decibels is poor, and the phenomenon of “tinnitus” may occur. Because our background sounds, such as cars passing by outside and neighbors watching TV, are below 80 decibels, the patient’s hearing processing may turn into tinnitus like cicadas, which is very annoying!
Cochlear hair cells are damaged and cannot be saved!
Hou Siren said that at present, except for sudden deafness such as firecracker injuries, which have a chance of recovery, hearing damage caused by damage to hair cells is actually irreversible. If the tinnitus interference is serious, the best way is to install hearing aids to improve hearing, so that there will be no tinnitus caused by poor sound reception. However, many people may not be able to accept the necessity of wearing hearing aids at once, so they can try anti-anxiety drugs. Reduce the sensitivity of the cochlea to listening sounds and reduce tinnitus.
Many people can rely on some introductions from the public to think about what health foods they can eat and what drugs they can inject to repair the damaged auditory nerve. Hou Siren said that in fact, the damage to the auditory nerve is irreversible. It is recommended to eat more vitamin B complex and other nerve-stabilizing nutrients to slow down the process. Degeneration, but to avoid further damage to hearing, “stop accepting noise” is the most important thing! Don’t listen to headphones, avoid environmental noise, etc., otherwise it will definitely continue to degrade.
