This type of neuropathy is also referred to as Auditory Dys-synchorony(AD) or Auditory Neuropathy Spectrum Disorder (ANSD). It is sometimes referred to as neural or nerve deafness.
It is a problem with the auditory nerve. With this type of hearing loss, the inner ear receives sounds normally, but the information is not transmitted via the auditory nerve to the brain. The sound may be disorganized or the nerve may not process the sound.
The result is hearing loss to some degree from the mild to profound, it is not predictable. It can create difficulty understanding spoken words, especially in noise. Sounds tend to fade in and out. Hearing can fluctuate from day to day or even from hour to hours.
Causes or risk factors
Auditory neuropathy can be caused by trauma or disease. The most common causes are lack of oxygen (anoxia) at birth, certain drugs especially those used to treat obstetric complications, ototoxic drugs (drugs that have a toxic effect on the ear or its nerve supply.)
Ototoxic drugs include antibiotics such as gentamicin, loop diuretics such as furosemide and platinum-based chemotherapy agents such as cisplatin. A number of nonsteroidal anti-inflammatory drugs (NSAIDS) have also been shown to be ototoxic.
Auditory neuropathy can also result from infectious diseases, immune disorders, neurological disorders such as Charcot-Marie-Tooth syndrome (which is believed to be genetic).
Medical management involves either the use of hearing aids or cochlear implants to improve hearing.
Ruling out nerve damage – the fact that those impulses are not reaching the brain may mean that the auditory nerve was in some way damaged. If there is nerve damage, it can be addressed using nutrients to allow the body to build healthy nerves.
