Why does neurogenic tinnitus occur and why does neurogenic tinnitus occur

Neurological tinnitus is mainly caused by the following reasons:

1.Patients continue to take drugs with ototoxicity in their lives, which may cause damage to the auditory nerve, which may lead to the appearance of neurological tinnitus;

2.As the elderly age, the auditory nerve and hearing function have degenerative diseases, which can also cause neurological tinnitus;

3.Patients with Meniere's syndrome or delayed hydrocedar may also have symptoms of neuropathic tinnitus;

4.If the patient has a lesion of the central nervous system, which affects the normal function of the auditory nerve, resulting in auditory nerve dysfunction, and can also cause the symptoms of neurological tinnitus, symptomatic medication is required**.

To understand the type of nervopathic tinnitus, you need to know what type of nervose tinnitus is. The cause of the disease is thought to be due to lesions or dysfunction of the cochlea, auditory nerve, and central auditory pathways.

First, the main **.

1. Sensory tinnitus: the most common, most of which are related to drug-induced ototoxic tinnitus and senile tinnitus.

2. Peripheral neurological tinnitus: **Unknown, it may be related to the degeneration of nerve fibers causing inter-fiber interaction, or the slowing down of nerve fiber transmission.

3. Central nervous system tinnitus: tumors, vascular abnormalities, local inflammation, multiple sclerosis, etc., can occur in patients who invade the auditory pathway.

2. Predisposing factors.

The disease can be precipitated by the following conditions:

1. Psychological factors and sleep disorders.

2. Poor ear use or occupational exposure, such as too loud earphones and too long wearing time, can also induce tinnitus.

3. Presbycusis occurs in the elderly with age.

4. Trauma to the head or ears.

5. Toxic hearing loss caused by taking drugs.

6. Cochlear lesions, tumors, Meniere's disease and otosclerosis.

The cause of neurological tinnitus is generally unknown, and the diseases that cause acute neurological tinnitus are common such as sudden deafness, as well as acute otitis media and secretory otitis media, which usually do not exceed 3 months, and the history of chronic neurological tinnitus exceeds 3 months. Noise-induced tinnitus caused by long-term exposure to noise, Meniere's disease, vertigo, and reflux can lead to high-frequency neurological tinnitus or hearing loss. Most patients are caused by insufficient blood supply to the inner ear due to various reasons such as aging, hypertension, diabetes, heart disease, cerebrovascular disease, etc., resulting in cochlear damage, membrane labyrinth, and auditory nerve damage.

Hypertension, hyperlipidemia, arteriosclerosis or diabetic neuropathy can also lead to neurological tinnitus, as well as systemic diseases, such as hypertension, diabetes, hereditary diseases, etc., can also cause neurological tinnitus. Excessive stress can also lead to neurological tinnitus.

Symptoms of the appearance. In addition, the cause of neurogenic tinnitus in many patients is also related to the patient's rest.

If there is a problem with the auditory center, which is the auditory nerve, there will be tinnitus.

It is a multifactorial disease, infection.

Drug intoxication. Genetics, aging, autoimmunity, and auditory neuropathy can all cause the disease.

What are the causes of neural hearing loss?

Congenital factors. Genetic or chromosomal abnormalities.

and so on, resulting in defects in the development of auditory organs, and hearing impairment caused by the completion of service.

Fetal hearing impairment caused by maternal or childbirth factors during pregnancy.

Drug intoxication. Common ototoxic drugs include aminoglycoside antibiotics such as streptomycin.

Gentamicin. Glycopeptide antibiotics such as vancomycin.

Antineoplastic drugs such as nitrogen mustard, carboplatin, and ciszaplatin.

Wait. In addition to external factors such as drug dose, drug time and route, drug poisoning is also related to internal factors such as individual differences.

Degenerative factors of old age.

Degenerative changes that occur with aging (usually over 60 years of age) are usually caused by atrophy of spiral ganglion cells or changes in the properties of the cochlear basement membrane.

Autoimmune factors.

Sensorineural hearing loss due to damage to inner ear tissue due to autoimmune disorders is progressive and fluctuating. May be accompanied by tinnitus.

and vertigo. Auditory neuropathy.

Acoustic neuropathy is a disease with special clinical manifestations, and the main audiological features include loss or severe abnormality of auditory brainstem responses, normal otoacoustic emissions, loss or elevated threshold of stapedius reflex, and low-frequency hearing threshold loss in pure-tone audiograms.

Viral or bacterial infections.

The infection affects the auditory system and can cause unilateral or bilateral nonfluctuating** tone hearing loss, which is commonly deaf.

Infection with mumps.

Popular** Risk.

Wait. What are the triggers for neural hearing loss?

Noises. It is deafness.

It is also an important factor that directly causes hearing loss. If you work or live in a high-decibel noise environment for a long time, the hearing cells will gradually be damaged. Over time, tinnitus and hearing loss will occur.

Trauma. Craniofacial trauma, knocking, etc., which cause damage to the inner ear, can also induce neural hearing loss.

There are many reasons why you can get nerogenic tinnitus:1Neuropathic tinnitus may be caused by paralysis of local nerves.

2.It may also be caused by a local nerve lesion. After suffering from neuropathic tinnitus, there will be significant hearing loss, and there will be a buzzing sound in the ear area, which will affect normal life and work if not timed**.
