Method We recorded CAEPs at varying intensity levels to speech (i.e., /ba/) and tones (i.e., 1 kHz) to estimate auditory thresholds in normal-hearing adults ( n = 10) and children ( n = 10) and case studies of children with sensorineural hearing loss and ANSD. Thus, we studied CAEP estimates of auditory thresholds in participants with normal hearing, sensorineural hearing loss, and ANSD. However, cortical auditory evoked potentials (CAEPs) can be recorded in many such patients and have been employed in threshold approximation. However, no tests are available now to decide whether a child with ANSD might benefit more from a hearing aid or cochlear implant.Purpose Auditory threshold estimation using the auditory brainstem response or auditory steady state response is limited in some populations (e.g., individuals with auditory neuropathy spectrum disorder or those who have difficulty remaining still during testing and cannot tolerate general anesthetic). Some children benefit more from a cochlear implant than from hearing aids. Remote microphone systems can improve listening in noisy backgrounds. Some professionals recommend the use of remote microphone systems. Hearing aids must be set carefully to prevent damage to the parts of the ear that receive sounds normally. However, many children get limited hearing aid benefit or no benefit at all. What is the Current Treatment for ANSD?Ĭurrently, there is no medical treatment for ANSD. At this time, no tests can tell us if a child’s hearing will change. Other infants stay the same or even get worse. They may start to hear and speak within a year or two. Some newborn babies who have been diagnosed with ANSD improve over time. It may also show problems with hearing in noisy backgrounds. Ongoing testing may show a poor understanding of speech. Parents and doctors may not suspect hearing loss right away if an infant’s response to sound changes from day to day.Īs children get older, more hearing information becomes available. This may slow the identification of ANSD. They can be used in both newborn infants and older children.ĭepending upon what test is used for newborn hearing screening, some children with ANSD may pass the first hearing screening in the hospital. These tests include auditory brainstem response (ABR), acoustic reflex testing and otoacoustic emissions (OAE).
