otoacoustic emissions (OAE) – a tiny microphone is placed inside the ear canal to check whether the cochlear hair cells are working.Typically, a person with auditory neuropathy has little or no response auditory brainstem response (ABR) – electrodes on the ears and head detect brain wave patterns when the person is exposed to a series of sounds.This suggests a genetic component.Īuditory neuropathy is diagnosed using a number of tests including: other affected family members – some children with auditory neuropathy have similarly affected family members.other disorders – in rare cases, auditory neuropathy is associated with other neurological disorders such as Charcot-Marie-Tooth disorder and Friedrich’s ataxia.health problems at birth – such as premature birth, jaundice or low birth weight.particular medications – certain medications that are used to treat obstetric complications are thought to affect the inner ear hair cells in susceptible babies.health problems in utero – such as reduced oxygen supply to the fetus.the eighth cranial nerve (the combination of the cochlear and vestibular nerves)Īnyone can be affected, but known risk factors for auditory neuropathy in children include:.the connections between the hair cells and the cochlear nerve.The cause of auditory neuropathy isn’t known, but researchers suspect that a number of factors may be responsible, including damage to: When someone has auditory neuropathy, some of the structures within the ear may be working perfectly, but the information from the ear may be distorted on its way to the brain. The electrical impulses are interpreted by the brain and the sound is ‘heard’. The brain stem is located at the base of the skull, and is considered the ‘bridge’ between the brain and the spinal cord.
