Nerve deafness

Nerve Deafness or Sensorineural Hearing Loss is a type of hearing loss that occurs due to damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain.

Causes

Nerve deafness can be caused by several factors, including:

• Aging: Age-related hearing loss, also known as presbycusis, is a common cause of nerve deafness.
• Noise exposure: Long-term exposure to loud noise can damage the hair cells in the cochlea that transmit sound to the brain.
• Infections: Certain viral or bacterial infections can cause nerve deafness.
• Genetic factors: Some people may be genetically predisposed to nerve deafness.
• Ototoxic drugs: Certain medications can damage the inner ear, leading to nerve deafness.

Symptoms

The symptoms of nerve deafness can vary depending on the cause and severity of the hearing loss. They may include:

• Difficulty hearing high-pitched sounds
• Difficulty understanding speech, especially in noisy environments
• Tinnitus (ringing in the ears)
• Dizziness or balance problems

Diagnosis

Nerve deafness is diagnosed through a series of audiological tests, which may include pure-tone audiometry, speech audiometry, and otoacoustic emissions testing.

Treatment

Treatment for nerve deafness depends on the cause and severity of the hearing loss. Options may include:

• Hearing aids: These devices amplify sound to help improve hearing.
• Cochlear implants: These surgically implanted devices can help people with severe nerve deafness hear better.
• Assistive listening devices: These devices can help improve hearing in specific situations, such as watching TV or talking on the phone.
