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