With the increase of age, too many elderly friends will experience “deafness”. Statistics have found that the incidence of presbycusis in the population reaches more than 60%. Their quality of life and cognitive function will cause psychological barriers. Over time, the elderly will become reticent, suspicious, irritable, and even increase the incidence of Alzheimer’s.
There are many reasons for presbycusis. In addition to some of its own factors, such as high blood pressure, hyperlipidemia, diabetes, and other chronic diseases, some external factors such as environmental noise and alcohol caused by smoking can also cause deafness. In addition, these causes are treated, and generally speaking, the sooner the hearing aid is used, the better, so as to stimulate the ear nerves, try to maintain hearing, and avoid the continuous deterioration of speech recognition ability. If it is severely deaf, a cochlear implant is also required.
What is the difference between a hearing aid and a cochlear implant?
First of all, the reason for the work is different. Hearing aids are sound amplifiers, which use residual hearing to transmit the amplified sound to the auditory center of the brain. The cochlear implant is a sound signal processor that converts sound signals into electrical signals that can be recognized by the auditory nerve, which looks to recover, improve and rebuild the patient’s auditory function.
In addition, hearing aids are external complications, no harm to the body, generally do not produce complications, suitable for patients with residual hearing, hearing aids can be implanted. The cochlear implant needs to be surgically implanted. If the follow-up device can only replace the cochlear implant, there is a risk of complications. It is suitable for patients with severe and severe deafness, and those with continuous hearing loss. For people with hearing loss, choosing a hearing aid can achieve good results.
