What are the characteristics of deafness in the elderly, and what are the types of presbycusis?

1) Unexplained bilateral symmetrical hearing loss occurs over 60 years old, mainly in the elderly.

2) Hearing loss is a slow, progressive worsening that often goes unnoticed at first. With the decline of high-frequency hearing, the ability to distinguish speech is affected, and the patient can hear the sound but cannot hear the content clearly, and often needs to be repeated by others. Later, as the frequency of speech is impaired, the speaker is asked to raise his voice to converse with him.

3) There is often a phenomenon of auditory rejuvenation.

4) The resolution of speech is not proportional to that of pure tone hearing, which is called "phonemic decline". In most cases, pure-tone hearing loss is less severe than verbal hearing, and this phenomenon becomes more pronounced with age, that is, in many older people, although pure-tone hearing is basically normal, they still cannot understand the content of speech.

5) There is an age-related "additional" hearing loss in older people, resulting in worse speech function than younger people at the same hearing threshold level. There is also a tendency to underestimate one's own hearing loss.

6) In noisy environments, older people have worse understanding of language. Even though there is little loss of hearing acuity in older people, it is much more difficult to understand speech in a noisy reverberation environment than in young people with normal hearing. For older people with hearing loss, it is more difficult to understand speech.

7) Some patients with presbycusis can be accompanied by tinnitus, often high-frequency sounds. It starts out intermittently, appears in the dead of night, and then becomes persistent, and can be heard during the day. Tinnitus usually begins in the 30s and 40s, and its incidence increases with age, peaking at the age of 60 or 70 and then declining rapidly.

Most patients with tinnitus become "habitual" to tinnitus as they age, and the tinnitus will disappear spontaneously.

Presbycusis is generally sensorineural deafness, with symmetrical gradual hearing loss in both ears. Hearing loss is particularly pronounced at high frequencies, resulting in a significant decrease in speech recognition and resolution.

It may be accompanied by tinnitus, often a high-frequency sound, which begins intermittently, often occurs in the dead of night, and gradually becomes persistent, and can be heard during the day.

There is often a revival of hearing.

Verbal resolution is not proportional to pure-tone hearing, and in most cases pure-tone hearing loss is less severe than verbal hearing. This phenomenon becomes more pronounced with age.

Hearing loss progresses slowly and is only noticed after many years, and it is rarely difficult to talk to familiar people, but it is more hesitant to talk to strangers and more difficult to talk to in noisy environments.

Presbycusis is a degenerative degeneration of the auditory organs triggered by the aging process of the human body, which is related to genetics and one's own health status. Chronic diseases such as hypertension, arteriosclerosis, diabetes, and coronary heart disease can induce or aggravate hearing impairment.

In general, presbycusis has several distinctive features:

1. Graduality. It is difficult for patients to say exactly when they started, but they know that their hearing loss gradually worsens with age.

2. Symmetry. As long as the deafness is not particularly prolonged, most older people have a bilaterally symmetrical hearing loss.

3. At the beginning, there was obvious loss of high-frequency hearing.

4. The language recognition ability of patients with presbycusis is significantly reduced, and the result is that they can hear but cannot hear clearly.

1. Perceptual senile postural slippery wax deafness: This type of deafness is characterized by degeneration, damage, and reduction of pericochlear periperipherythral hair cells and supporting cells, and the patient's hearing in both ears is sharply reduced.

2. Nervous presbycusis: This type of deafness is mainly characterized by the degeneration of cochlear spiral ganglia and nerve fibers.

3. Vascular senile deafness: This type is also known as metabolic presbycusis, which is characterized by cochlear vascular atrophy.

4. Cochlear conductive presbycusis: This is a mechanical or cochlear conductive hearing loss characterized by decreased elasticity of the basement membrane.

5. Central presbycusis: It is mainly the degeneration of neurons at all levels of hearing, especially the auditory area of the cerebral cortex, which is also the main cause of speech and communication disorders in the elderly.

6. Mixed hearing impairment: Mixed hearing impairment is a mixture of the above-mentioned pathological types.

There are four main types of presbycusis: sensorineural presbycusis; neurotyped presbycusis; vascular presbycusis; Cochlear conduction presbycusis. Each type of deafness has its own characteristics, and it is necessary to choose the appropriate way according to different types.

For elderly deaf patients, the dust wheel needs to improve the type of deafness and other related examinations such as electrical audiometry, and choose the appropriate method according to the type of deafness.

Hello, your question: What are the causes of deafness in the elderly? The main causes of presbycusis are:

1. Age factor: with the increase of age, hearing deterioration gradually aggravates, but individual differences are very large; 2. Disease first: patients with hypertension, atherosclerosis, diabetes, hyperlipidemia, coronary heart disease and other diseases are susceptible to this disease; 3. Zinc deficiency in the body

The influence of dietary habits: the elderly eat more vegetarian food, the incidence of coronary heart disease is less, and the hearing is better maintained; The elderly are mainly meat-eaters, have high blood cholesterol, high incidence of cardiovascular diseases, and poor hearing in the elderly. Effects of long-term noise:

According to the survey, the onset of deafness in the elderly in urban residents is earlier than that in rural areas, especially the elderly over 65 years old, who can maintain better high-frequency hearing. There are many reasons for this, but long-term noise damage is one of the main causes. Influence of genetic factors:

Under 65 years of age, there is a family history of deafness, with a flat or pelvic hearing curve; Over 65 years old without a family history of deafness, downhill hearing curve, low language recognition rate, genetics dominant, genetics, genetics, men and women are also different, female tissue tolerance is stronger than men, and men are more likely to be exposed to harsh environment and noise than women, smoking and drinking more than women, so presbycusis is twice as much in men than women. Affected by aging: due to bone hyperplasia and deposition, the elderly narrow or occlude the bony orifice and tubule in and near the inner ear, the corresponding nerve fibers and spiral ganglion atrophy, and nerve cells decrease, which may be another ** of presbycusis**.

Hello, there are many reasons for hearing loss in the elderly, such as: family hereditary, long-term work or life in a noisy environment can also cause hearing loss, trauma, aging ear function deterioration, various diseases and chronic diseases affect the microcirculation of blood in the ear will also lead to hearing loss, the reasons are many and complex. I hope my answer is helpful to you.

Hello, what are the causes of deafness in the elderly? Deafness in the elderly is associated with the decline of general body function and the microcirculation disorder of the cochlea in the inner ear with age. Diet, environment, senile diseases, ototoxic drug use can all affect.

The daily diet should be scientific and reasonable, quit smoking and drinking, avoid a diet high in sugar, high salt, high cholesterol and low fiber, combine work and rest, be optimistic, participate in social activities, and exercise appropriately. If you have hearing problems, check it up promptly**. I hope my answer will help you.

Hello! What are the causes of deafness in the elderly?

1. Good living habits and regular work and rest.

2. Healthy eating habits.

3. Be cautious with ototoxic drugs.

4.Reduced noise exposure.

5. Insist on strengthening physical exercise.

Hello, there are many causes of deafness.

There are dietary, physical diseases, and genetic factors. It is recommended to go to the hearing center regularly to check the changes in hearing attention and intervene in time after discovering changes, and pay attention to ear habits daily to avoid ear canal inflammation and cerumen embolism. I hope my answer is helpful to you.
