When there is hearing loss, due to the obstruction of sound signal conduction or the reduction of the inner ear's sound sensing ability, the actual signal sent to the brain is reduced, and the brain must work harder to judge the original sound signal based on the only residual signal. As a result, daily listening to sounds can easily cause fatigue, which we call "auditory fatigue", which undoubtedly makes our life and work more and more tiring.


Can hearing loss cause dementia in the elderly?

People with poor hearing have a higher risk of suffering from Alzheimer’s disease. Poor hearing will affect the psychology of the elderly, causing them to have weaker social skills, low self-esteem, and unwillingness to talk more and contact the outside world. They close themselves off and become introverted and withdrawn. Over time, they become even less willing to open their mouths to speak. Therefore, using hearing aids in time to help the elderly listen better can greatly reduce the chance of the elderly suffering from Alzheimer's disease.


The relationship between hearing loss and Alzheimer’s disease. Hearing loss itself will not directly cause Alzheimer's disease. If you have hearing loss, if you do not intervene, you will have less communication with the outside world. This will lead to less information input and less communication, and the brain will naturally become inflexible, which may lead to Alzheimer's disease. So what we want to tell the patient’s family at this time is: hearing loss requires early intervention, otherwise it will lead to Alzheimer’s disease. For example, it is better to say that a person's left hand and right hand are both good and normal. But my right hand is very flexible when writing, and my left hand suddenly cannot write well when holding a pen. There is no disease in the left hand itself, but the flexibility of the left hand will be much worse. The same is true for the relationship between hearing loss and Alzheimer's disease.


Hearing loss can lead to communication and cognitive impairment and emotional depression. The incidence of Alzheimer's disease among elderly people with mild, moderate and severe hearing loss is respectively 2, 3 and 5 times that of those with normal hearing. Hearing loss is an independent high-risk factor for Alzheimer's disease and has now become the most prominent health problem in the global aging population. It is recommended that if you have hearing loss, you can compensate by wearing a hearing aid.


Hearing loss will not only cause hearing difficulties, but also affect the vestibular system, leading to an increased risk of falling, thereby increasing the risk of accidental death for the elderly. Research has confirmed that even mild hearing loss triples the risk of accidental falls; and for every 10 decibel loss in hearing, the likelihood of falling increases to 1.4 times that of a person with normal hearing.
