What is nervous deafness?
nervous deafness, also known as sensorineural hearing loss, is the condition of the ear, whose symptoms include reduced hearing capabilities or overall deafness due to damage to inner ear. It affects millions of people at different degrees of severity. The condition may be the result of defects present at birth, referred to as congenital defects or symptoms obtained later in life. Most nervous deaf occurrences are attributed to the abnormalities of hair cells placed in the inner ear.
irreversible damage to parts of the inner ear, specifically the hair cells found in the cochle, distinguishes nervous deafness from other hearing loss conditions, although very rare cases of hearing centers and cranial nerves have been discovered. Damage to the hearing processors of the brain leads to a more serious sensorineural deafness called central hearing loss, which is marked by the inability to interpret sounds, so that the speech is degraded. Most cases of deafness nerve occur when hair cells are damaged, which killIt rains the transfer of sound information to the acoustic nerve and causes a certain degree of deafness. The number of abnormal hair cells determines how serious hearing loss will be.
Inner ear cell injuries or destruction of inner ear cells could stem from congenital sources, inherited dominant or recessive genes associated with hearing loss or external influences, such as infection, disease or trauma. The acquired nervous deafness was associated with abnormalities and diseases of almost every organ system, side effects of some drugs and physical injuries. A lifestyle can also lead to such trauma, which includes constant exposure to loud sounds such as daily use of headphones at full volume. Some of the acquired causes may cause rapid hearing loss called a sudden sensorineural hearing loss, which is usually distinguished within the weeks of the weeks.
nervous deafness that youHe knows from inherited dominant or recessive genes, it may be syndromical, which concerns the loss of hearing that occurs along with abnormal symptoms in other parts of the body or nesyndromical. The presence of a dominant gene of deafness in the family requires only one parent to transfer and give the gene to children to manifest itself. This usually causes hearing loss that continues with family members from one generation to another.
Accurate diagnosis of nervous deafness involves rapid screening tests for hearing and audiometry. If nervous deafness is discovered, electroacoustic audit aids can be used for mild to medium cases, which are placed in the ear or by the ear. Deep hearing loss could require the use of cochlear implant, which requires surgery to insert the internal component of the device.
