Is deafness in the elderly related to bleeding in the inner ear?

British researchers pointed out that deafness in the elderly is caused by the gradual blockage of blood flow in the inner ear. Experts have conducted blood samples on more than 140 patients with varying degrees of deafness, and the results show that those with excellent hearing have the thickest plasma.

It turns out that there are many hair cells on the cochlea of the inner ear that can sense the vibrations of sound waves, allowing the person to hear sounds. These hair cells are made up of thin microvessels** blood, and if blood flow is blocked, the hair cells die.

Researchers have found that for blood to pass through the microvessels at the hair cells of the inner ear, the red blood cells in the blood must change their shape. Because the diameter of the microvessels at the hair cells is only 4 5 microns, while the diameter of the red blood cells is about 7 8 microns, the red blood cells have to be bent and deformed to pass through the blood vessels with such a narrow diameter. As people grow older, the microvasculature will gradually narrow, and the deformation ability of red blood cells will also decrease, resulting in a decrease in the blood volume of hair cells, and the nutritional status of hair cells will deteriorate and die, so the phenomenon of senile deafness will occur.

Experts remind everyone that although human aging and degradation are irresistible physiological processes, if you do not smoke, do not drink alcohol, often pay attention to dietary hygiene, diversify your daily diet, and pay attention to eating iron-rich foods such as animal liver, lean meat, pig blood, soy products, green vegetables, etc. In addition, with regular exercise, deafness appears later.

If it is carried out within a week, 90% of patients can slowly recover their hearing, if they delay for too long, it is impossible to recover their hearing, if there is a sudden loss of hearing, it is necessary to go to the hospital in time to check the pure tone hearing threshold examination to understand the hearing, check the sound conduction antimetry to understand the middle ear, and then target**. Pay attention to rest, get enough sleep, be emotionally stable, avoid noise, do not listen with earbuds**, use less mobile phones, drink more water and eat more fresh vegetables and fruits.

Well, according to many medical researchers, deafness in the elderly is caused by the gradual blockage of blood flow in the inner ear, researchers have conducted blood samples on more than 140 patients with varying degrees of deafness, and the results show that the hearing and parent plasma are the thickest.

There are many hair cells on the ears of humans, and he can perceive the vibrations of sound waves, so that people can hear the sounds, and these capillary cells are cells** blood, and if the blood flow is blocked, the cat cells will die.

The red blood cells in the blood must change their shape because the diameter of the microvessels at the hair cells is 4 to 5 microns, and the diameter of the red blood cells is 7 to 8 microns. Deterioration of the nutritional status of the hair cell mass and death is a phenomenon of senile deafness.

Some researchers remind everyone that although human aging and degeneration are irresistible physiological processes, if you do not smoke, do not drink alcohol, often pay attention to dietary hygiene, diversify your daily diet, pay attention to eating rich foods, such as pig blood, soy products, green vegetables, etc., and exercise regularly, deafness will appear later.

At present, about 1 3 elderly people have varying degrees of hearing loss, but there are very few people who choose hearing aids. There are a lot of misconceptions here. It is understood that about 1 3 of the elderly over 65 years old in China will have hearing loss.

Senile hearing loss is caused by the physiological degeneration of hair cells and auditory nerves, hair cells can not be regenerated, and medicine and surgery can not be used, so the deaf elderly can only choose hearing aids. Due to the "use-in-use" nature of hearing, wearing hearing aids as early as possible can help delay the progression of hearing loss.

As we get older, the nervous system will of course deteriorate a little, resulting in poor hearing in the ears, which is not unusual; What else can I do, take the elderly to check, if there is no inflammation in the ear, with a hearing aid, many elderly friends rely on Shenma hearing aids, walkers!

There are many causes of deafness in the elderly, and in recent years, experts have found that hyperlipidemia is also an important cause of deafness in the elderly.

Therefore, for the elderly with hyperlipidemia, they should actively hyperlipidemia and eat less high-fat and high-cholesterol foods, which not only helps to prevent atherosclerosis, but also is also beneficial to prevent presbycusis. Vegetable fats such as walnuts, pine nuts, and hazelnuts contain polyunsaturated fatty acids, which can lower blood cholesterol, so regular consumption can help prevent presbycusis, especially for those with hyperlipidemia. Fish oil, especially the fats contained in certain marine organisms, are also rich in polyunsaturated fatty acids, which not only lower blood cholesterol, but also adjust the balance between prostaglandins and thromboxane A2, thereby anti-platelet aggregation.

There is nothing directly related.

The two can be separated.

It has been reported that more than 1 in 4 patients with advanced tone neural hearing loss have hyperlipidemia, while 1 in 2 patients with hyperlipidemia have inner ear dysfunction and coronary artery disease. Elevated blood lipids can promote arteriosclerosis, lipid deposition and thickening of the walls of labyrinthine arteries, cochlea and vestibular arterioles, varying degrees of narrowing of the capillary lumen, increased blood viscosity, and disorders of inner ear microcirculation. Platelet aggregation function is enhanced, coagulation factor activity is increased, and microvascular plugs can be formed in the inner ear microcirculation, reducing blood flow and oxygen supply, resulting in atrophy of pericochlear vesselae, spiral ganglion cells and degeneration of internal and external hair cells, resulting in deafness.

In addition, hyperemia can also cause an increase in lipid peroxide in the blood, which can directly damage the hearing organ of the inner ear.

Hyperlipidemia can cause lipid deposition in the inner ear, increase in lipid peroxide, directly lead to inner ear cell damage, vascular atrophy, and thus cause presbycusis. In addition, patients with hyperlipidemia have increased blood viscosity, increased platelet aggregation, and are prone to atherosclerosis, and the inner ear artery has no collateral circulation, slow blood flow, and insufficient blood supply can cause microcirculatory perfusion disorders in the inner ear, which in turn affects the hearing of the inner ear.

Therefore, hyperlipidemia needs to be paid attention to preventing deafness.

As he grows older, the function of his hair cells may decline due to various reasons in daily life, so it may be that the older he gets, the more he loses his hair cells, and he is more likely to be deaf. In the second elderly person, after the function of the cochlea in the ear deteriorates, the entire blood supply slowly deteriorates.

It is true that the incidence of deafness in the elderly is relatively high, and a current survey found that about 33% of the elderly will be deaf.

When deafness occurs in the elderly, many people's diagnosis is understood to be old and neurodegenerate, which is actually the elderly do have this kind of functional neurological degeneration, and other reasons.

Another is that there have been many recent studies that have found that one of the reasons for the deafness of the elderly may be because of the ear, and finally his neural deafness, he depends on the function of the cells inside, the cells of this person's ear are different from the cells of the **, it is non-renewable, that is, a cell dies and dies one, just as the age grows because of various reasons in daily life, it is such as this strong sound may cause a decline in the function of this hair cell, so it may be older The more he loses his hair cells, the more deaf he becomes.

The second is the ear of the elderly, after the function of the cochlea degenerates, its entire blood supply slowly deteriorates, which is also an important cause of deafness.

First of all, because the elderly gradually degenerate with age, the function of the typanic tube is abnormal. This can cause deafness.

The second is that the body of the elderly is relatively weak in qi, and they are easily fatigued, lack of yang qi, and cannot go through the ears.

In addition, it is possible that neurological tinnitus causes deafness, due to cerebral infarction, anemia, diabetes and other diseases. can cause deafness. If necessary, it is recommended to go to the hospital for an MRI and audiological test.

I wish everyone who is deaf will be able to do it soon**.

I think it should be due to senile ear loss, and as people age, the auditory system will age, and some hair cells in the inner ear will degenerate and die, resulting in cell death or a decrease in the number. To a certain extent, it can cause the function of the ear to deteriorate, causing auditory dysfunction. 2. The most common ear damage caused by diseases is hypertension and arteriosclerosis, which cause blood supply disorders in the inner ear, increased blood viscosity, and lipid metabolism disorders in the inner ear and cause hearing changes.

In diabetic patients, the persistence of hyperglycemic states can damage the microcirculation and blood vessels of organs throughout the body, resulting in a lack of oxygen in the inner ear, and blood sugar can also damage the nerves and tissues in the ear, increasing the risk of hearing loss. 2. The occurrence of senile ear loss is a natural phenomenon of human aging. At present, there is no effective way to reverse this phenomenon, and it can only be detected early and through some first-class means to improve the patient's partial hearing or slow down the rate of progression of his ear loss.

1. Drugs include drugs that dilate blood vessels, improve inner ear microcirculation, neuronutrition and protection, have the effect of calming the nerves and nourishing the heart, and Chinese patent medicines that have the effects of blood circulation, blood stasis, and qi opening. 2. Hearing aid selection For most patients with presbycusis, hearing loss is already moderate hearing loss, and when the drug is not effective, it is necessary to wear hearing aids to help improve hearing. What do hearing aids do?

Hearing aids are instruments that help improve hearing, and their function can make weak sounds be amplified and transmitted to the headphones, so that the parts of hearing loss can hear the sound with the help of amplification.

The pathogenesis of presbycusis is more complex, it is not clear, some data show that in elderly patients with hyperlipidemia, the incidence of presbycusis is significantly higher than that of normal blood lipids, hyperlipidemia promotes sensia, in addition to the degeneration of external hair cells and blood vessels due to lipid deposition, platelet aggregation and erythrocyte stasis, microcirculation disorders, it may also be related to the direct damage of lipid peroxide to biomembranes and hair cells in auditory receptors, cochlear base weekend spiral apparatus and related nerve atrophy, Therefore, it is characterized by a slow progression of bilateral and sensorineural hearing loss dominated by a decrease in high frequencies.

In addition, due to bone hyperplasia and deposition in the elderly, the inner ear auditory canal and nearby bony orifice and tubule narrowing or occlusion, the corresponding nerve fibers, spiral ganglion atrophy, nerve cells decrease, this may be another ** of presbycusis, it should be admitted that presbycusis is an aging phenomenon manifested in hearing, basically in line with the law of metabolism, and no ** can change this law and trend.

The general cause of deafness and tinnitus and other diseases in the elderly is the aging of hearing organs, cardiovascular and cerebrovascular diseases or organ diseases, such as the deterioration of heart, liver and gallbladder functions, ** is the lack of trace elements, which is also the main reason, and then the long-term environment will also lead to deafness and tinnitus and other symptoms.

Because everything is in the process of development and change, as the elderly age, the organs of the body also age, the function decreases, the hearing decreases, and the appearance of deafness is also relatively common, so there is no need to make a fuss.

The causes of deafness are: (1) infectious disease-derived deafness: various acute infectious diseases, bacterial or viral infections, such as Japanese encephalitis, mumps, purulent meningitis, measles, scarlet fever, epidemics, otic shingles, typhoid fever, etc., can damage the inner ear and cause sensorineural hearing loss of varying severity.

2) Sudden deafness: It is a kind of sensorineural hearing loss that occurs suddenly and the cause is unknown. Acute vascular occlusion and viral infections are thought to be common causes.

Lesions may involve the spiral apparatus or even rupture of the vestibular membrane or cochlear membrane. Deafness can manifest instantaneously or reach its peak rapidly within hours or days, usually unilateral, with both ears with tinnitus and vertigo. Good results can be obtained in the early stages**.

3) Drug toxicity deafness: more common in aminoglycoside antibiotics, such as gentamicin, kanamycin, polymyxin, dihydrostreptomycin, neomycin, etc., other drugs such as quinine, salicylic acid, cischloroplatin, etc. can be caused, sensorineural hearing loss, ear drug poisoning and the body's susceptibility is closely related. Drug-toxic deafness is bilateral, often accompanied by tinnitus, and vestibular function can also be impaired.

Long-term instillation of these drugs in the middle ear can also penetrate into the inner ear through the cochlear membrane, which should be noted.

4) Traumatic deafness: Traumatic brain injury, temporal bone fracture damages the inner ear structure, resulting in inner ear bleeding, or inner ear injury caused by strong **, which can lead to sensorineural hearing loss, sometimes accompanied by tinnitus and vertigo. The mild ones can be recovered.

Ear surgery can also cause deafness if the inner ear structure is accidentally injured.

5) Presbycusis: due to senile arteriosclerosis and bone hyperplasia, the spiral hair cells and spiral ganglion are insufficient, degenerative diseases occur, or the central nervous system declines, resulting in hearing loss.
