Is senile deafness related to senile dementia?2021-10-15
Senile deafness, also known as age-related hearing loss, is a hearing impairment caused by the aging of the auditory system, and a binaural symmetrical sound hearing abnormality with the increase of patients' age. According to China's epidemiological survey, 35% ~ 55% of people over 60 years old have different degrees of hearing impairment. According to the prediction of the United Nations, by 2050, the population over the age of 60 will reach 491 million, accounting for more than 1 / 3 of the total population.
Alzheimer's disease is the most common form of Alzheimer's disease. It is a degenerative disease of the central nervous system. The onset is insidious and the course of disease is chronic and progressive. The main manifestations of the disease are neuropsychiatric symptoms such as progressive memory impairment, cognitive impairment, personality change and language disorder, which seriously affect social, professional and life functions.
More and more studies show that there is a close relationship between senile deafness and senile dementia. According to the survey data of the World Health Organization, the prevalence of Alzheimer's disease in the elderly with mild, moderate and severe hearing loss is twice, three and five times that of the elderly with normal hearing, respectively.
We can hear and understand sounds, not just the role of ears. The sound is transmitted to the inner ear through the outer and middle ears. The cochlea of the inner ear converts the sound into nerve impulses, transmits it to the auditory center of the cerebral cortex through the auditory nerve, and connects with the language center, so as to finally understand the meaning. Some studies have shown that hearing loss is related to the reduction of temporal lobe volume in hippocampus and entorhinal cortex, which is mainly responsible for people's memory and emotional ability. Therefore, once hearing is lost or decreased, our cognitive ability will be greatly reduced, which will eventually aggravate the progress of cognitive impairment and lead to Alzheimer's disease.
Early detection, early intervention and early rehabilitation can prevent "dementia caused by deafness". Therefore, it is suggested that when the elderly show signs of hearing loss or have formed hearing loss, the elderly should not "avoid talking", but "take the initiative", actively listen, actively rehabilitate and actively participate in social activities.
In addition, through relevant studies, it is found that for elderly patients with cognitive impairment who have suffered from hearing impairment, early intervention of auditory function should be implemented. Most scholars have reported that the behavior, functional status and quality of life of elderly patients with cognitive impairment with hearing impairment have been improved after using hearing aids.
