Neural Hearing Loss

Neural Hearing Loss

The neural hearing loss or deafness is a most common hearing loss. In this nerve and auditory systems are unable to transmit information to the brain. People who are suffering from this disability, face difficulty in understanding speech, even it is loud enough, especially in background noise. Also diagnosing this hearing loss is extremely difficult. Due to this, it usually gets grouped under the category of “sensorineural” hearing loss.

When the auditory nerve which carries impulses from the cochlea to the brain is missing or abnormal we term it as Neural hearing loss.

Causes

There are a number of causes by which hearing loss occurs. N0w you might have the curiosity to know these causes, there is a brief discussion below.

Genetic- In some cases, the neural hearing loss may happen genetically and it will go along. This chain of hearing loss may continue to generations if not cured.

Acoustic tumors- Health problems like tumor may also occur due to the hearing loss.

In – utero exposure to certain infections- Infection may also occur due to hearing loss which can also affect the auditory nerve.

Severe jaundice in infancy- The baby’s blood contains an excess of bilirubin, a yellow-colored pigment of red blood cell. A high bilirubin level associated with severe infant jaundice may result in a neural hearing loss.

A low birth weight associated with premature birth- Premature birth can be the cause of the neural hearing loss that can affect the child.

How do I identify the exact location of the neural hearing loss?

It is hard to find out the exact location of the neural hearing loss. The exact location is not always evident to the hearing specialist. The nerve that carries impulses from the cochlea to the brain is damaged due to that neural hearing loss. It is one of the most common hearing loss. The hearing specialist also recognizes that to find out the exact location is not easy.

Diagnosis and treatment

In its treatment amplification may be recommended in some cases depending on the damage to the hearing nerves. It is diagnosed by radiographic imaging and difficult to identify the exact location of the neural hearing loss using current equipment.

In some cases amplification is not recommended by the ENT specialist and sometimes an individual will be able to hear sounds properly at normal intensity but they face difficulty in understanding speech. In these making sounds louder with hearing aids does not improve speech understanding. Any individual with neural hearing loss is faced more trouble in the background noise than it actually has. There are various research and studies are regulated to treat neural damage. Some researchers are currently in use such as auditory nerve implants.
