Gao Zhiqiang, director of otolaryngology and otolaryngology at Beijing Union Hospital: senile deafness refers to hearing loss caused by hearing loss with age. Some studies have shown that the incidence of deafness in the elderly is as high as 30% to 60%, and the number of diseases is increasing year by year. Because of the large number of sick people, high incidence, and many elderly people ignore the harm of hearing loss, let it develop, resulting in a series of adverse consequences.
The causes of deafness in the elderly, in addition to the natural aging of the auditory system, are related to genetic factors (making the auditory system vulnerable), atherosclerosis (causing obstruction of the cochlear microarterials), intake of oversaturated fatty acids (aggravating atherosclerosis), diabetes (causing endothelial hyperplasia of the cochlea, reducing blood supply), smoking (exacerbating atherosclerosis), noise and ototoxic drugs.

Chief otolaryngologist zhang qiuying of beijing hospital, chief physician xu jin: the body's hearing nerve is like a telephone line, there are many fibers inside, wrapped around a layer of myelin sheath. With the increase of age, the myelin sheath will be damaged and lost, which will affect the hearing function and cause hearing loss. Therefore, the elderly often interrupt when talking, often only hear its sound, do not understand its meaning, these are the biggest characteristics of senile deafness. Deaf old people's ability to understand language will also decline, always require the other side to repeat, seriously affect communication. The voice is muted and loud and noisy because senile deafness is neurotic and the threshold of tolerance to sound changes. Still some old people are too sensitive to individual sounds, feel uncomfortable, like to stay in a quiet environment. Because of the fear of being ridiculed and giving others trouble, deaf old people often escape communication, self-closure, become lonely or irritable, easy to cause Alzheimer's disease.
Although aging is a natural rule, the age and progress of deafness in the elderly vary from person to person. So how to prevent or delay the occurrence of senile deafness? First of all, we should avoid noise stimulation, listen to headphones and watch TV lower the volume; actively prevent and treat chronic diseases such as hypertension and hyperlipidemia; be careful to use ototoxic drugs; control the intake of fat and visceral organs in animals, eat more foods rich in vitamin C and vitamin E, help eliminate pathogenic free radicals; quit alcohol and tobacco; find hearing loss and go to hospital as early as possible.
Wang Jing, deputy chief physician of the department of otolaryngology in the hospital affiliated to Fudan University: How can we prevent the further development of the disease? In fact, senile deafness and any kind of sensorineural deafness, as long as more than 2 months is more difficult to treat. Therefore, it is recommended that everyone consult a doctor in time when hearing loss is found, doctors will provide reasonable advice and treatment according to the condition, and generally use some drugs to improve the microcirculation and nutrition nervous system. These drugs may not improve until they are regularly administered for 2-3 months.
The more severely ill older people need to wear hearing aids. However, it should be noted that because of the particularity of senile deafness and the inevitability of the degeneration of the nervous system in the elderly, the very serious people with hearing aids will not achieve very good results. Abroad, older people with senile deafness improve their hearing by installing an electronic cochlear implant. People's Health Network
