Many of us think that hearing loss is just a worsening of hearing and will not affect physical health. However, if no intervention is taken for hearing loss, it will not only affect our lives, but also cause damage to our own health, especially mental health, beyond our imagination. As the chance of neurasthenia greatly increases, hearing problems will also become more severe.


Will hearing problems affect brain response?


Hearing loss will affect the brain’s response. The brain receives sound signals and begins to analyze and judge. The perceptual abilities of listening, speaking, and reading are all directed by the brain. When this aspect of the brain gradually declines, it will inevitably affect the cognitive abilities of hearing-impaired people in listening, speaking, reading, etc. The cognitive functions of the brain rely on the auditory nerve. Systemic sensory input, hearing damage will seriously affect the brain's speech recognition ability.

The external stimulation caused by hearing loss to the brain is an important factor that affects the inability of patients with senile hearing loss to recognize speech. Research has found that the impact of age-related hearing loss on the brain is mainly manifested in two ways: cortical reorganization and cognitive decline.


The function of the auditory cortex of the brain is divided into two parts, the "hearing" area responsible for receiving sounds, and the "hearing and responding" area responsible for processing sounds.

For patients with senile hearing loss, hearing loss will cause the auditory cortex of the brain to atrophy, causing the auditory cortex that is originally responsible for "reacting" to be used to "hear" sounds. The cerebral cortex, originally responsible for vision and touch, expands to replace the auditory cortex, gradually exacerbating the changes in the brain caused by hearing loss.


Therefore, the reorganization of the cerebral cortex caused by hearing loss will gradually reduce the recognition of sound information in patients with senile hearing loss, and then gradually appear "clear hearing, slow response, The impact of symptoms such as "unable to distinguish speech"

Because Hearing Aids only help to hear sounds, and distinguishing sounds still depends on one's own speech discrimination ability. Everyone's speech discrimination ability is different. This is related to the nature of hearing loss. , duration and degree are all related. Relatively speaking, one-on-one communication in a quiet environment is more effective than a noisy environment, and it is also more effective than multiple people talking at the same time. If you wear a hearing aid, you must learn listening and communication skills to achieve the best use effect.
