The longer the deafness lasts, the worse the ability to distinguish speech, right?
The longer the hearing loss lasts, the auditory center’s memory of some words will become increasingly blurred, and eventually there will be no memory at all. Without timely intervention, the understanding of many words will weaken, even if You can hear sounds but don't know what to say, and speech resolution will become very poor.
In fact, the ears mainly play the role of collection, amplification, conduction, etc. In the end, whether you can distinguish various sounds and hear speech clearly, the brain plays a big role , which processes auditory signals. Therefore, poor hearing and poor distinguishing ability can certainly be considered to be "problems" with the brain. But the so-called "problem" obviously cannot be compared with brain tumors, brain inflammation, or mental retardation.
The longer you are deaf, the ability to distinguish sounds will become worse and worse. Many hearing aid wearers report that they can hear well face-to-face, but the main reason why they cannot hear clearly without looking at the mouth shape. In fact, it is because the hearing aid is not worn in time and the long-term dependence on mouth shape leads to weak auditory discrimination ability. The degree of dependence on the final incomprehension is related to the degree of hearing loss. Therefore, when you feel that your hearing has declined significantly, you should take measures such as wearing a hearing aid as much as possible to intervene.
So, what’s wrong with your brain when you have poor hearing or even poor discernment?
The suppression of the auditory pathway caused by hearing loss undoubtedly reduces the input (stimulation) to the brain. As the saying goes, use it or lose it. Hearing loss is directly related to the atrophy of the auditory cortex of the brain.According to data disclosed at the Second World Health Organization Collaborating Center for Deafness Prevention Strategic Planning Meeting, the prevalence of Alzheimer’s disease among elderly people with mild, moderate, and severe hearing loss is respectively 2 times, 3 times and 5 times for the elderly.
A very interesting coincidence is that the former President of the United States, Ronald Reagan, first became deaf and later developed symptoms of Alzheimer's disease.
Therefore, when hearing loss is discovered, early diagnosis and early intervention are key. Don’t wait until the hearing becomes more and more severe and the sound discrimination ability becomes worse and worse. At this time, it may not only be If there is a problem with the ears, the problem with the brain cannot be eliminated. It is already too late!
