For the problem of the elderly, only for the deafness of the elderly, once people get old, their organs degenerate very strictly, and hearing loss is common. The following is the content about the causes of the sudden deafness of the elderly, which I sorted out for your reference and understanding!
1. Long term exposure to noise can increase the risk of deafness in the elderly.
2. In mental stress, long-term mental tension can cause nervous system disorders, which affect the blood supply of inner ear and lead to deafness.
3. Dietary habits lead to the lack of zinc, which affects the function of cochlea, and then leads to the occurrence of senile deafness.
4. Vascular diseases such as hyperlipidemia and hypertension can narrow the vascular cavity and reduce the elasticity, affect the blood flow of the inner ear, ischemia and hypoxia of auditory nerve cells, and lead to deafness.
5. Age can degrade the central nerve and inner ear nerve, resulting in deafness; The eustachian tube can also harden and narrow with age, affecting the physiological function of the eustachian tube and leading to deafness.
1. It can be accompanied by tinnitus, often high-frequency sound. It starts intermittently, appears in the dead of night, then gradually becomes continuous, and can be heard during the day. Tinnitus often begins at the age of 30 ~ 40, and its occurrence rate increases with age, reaches the peak at the age of 60 ~ 70, and then decreases rapidly. Most patients with tinnitus feel "used" to tinnitus with age, and tinnitus can disappear automatically in the future.
2. There is often auditory revitalization, that is, patients often say that "others can't hear when they speak in a low voice, but they feel too noisy when they speak loudly". It often appears when someone turns a deaf ear to him when asking for a loan, and can hear him clearly when scolding him. This is because when borrowing, they are in a low voice, and when swearing, they are in a high voice, so it is easy to be misunderstood as "pretending to be deaf and dumb".
3. Language resolution is out of proportion to pure tone hearing. In most cases, pure tone hearing loss is less serious than language hearing. The older the age, the more obvious this phenomenon is, that is, in many elderly people, although pure tone hearing is basically normal, they still can't understand the content of speech.
4. Hearing loss progresses slowly and is found after years and months. The old man talks and laughs happily when meeting with acquaintances and has few difficulties, but when talking with strangers, he will hesitate and answer irrelevant questions. Feel more difficult in noisy environment, especially in group activities in which many people participate.
Experts remind that the deafness of the elderly has always been a problem perplexing the health of the middle-aged and elderly, which should be solved as soon as possible.
In daily life, we often hear that some people sleep all night and suddenly find that one side of their ear is deaf when they get up for breakfast the next day. These patients mostly occur after colds, excessive fatigue and emotional fluctuations. Some of them occur in an instant, no more than 24 hours at most. Their deafness reaches the peak within 24 hours. They are diagnosed as "sudden deafness" in the hospital. The onset of this disease is sudden and common in healthy adults. It is more common in middle-aged people. There are slightly more women than men. There is no omen before the onset, and there is often no obvious conscious reason.
The etiology of this disease is often not very clear. Most scholars believe that it is related to the following lesions: one is vascular disease, the other is viral infection. Third, autoimmune diseases. Fourth, rupture of membranous labyrinth. Therefore, sudden deafness is not the damage of sound transmission route, but the damage of sensory sound part of inner ear.
The main symptom of this disease is deafness, varying degrees. Generally, it will not be completely deaf. Most of them will have residual hearing, often accompanied by tinnitus, mostly low pitched, sometimes there is a sense of blockage in the ear, and some are accompanied by varying degrees of vertigo.
The prognosis of sudden deafness is better than that of other neurological deafness. Some can recover naturally without treatment, but the recovery process is different. Therefore, active treatment can still obtain better curative effect, and the sooner the better.
