Auditory neuropathy spectrum disorder
Auditory neuropathy spectrum disorder (ANSD) is a specific form of hearing loss defined by the presence of normal or near-normal otoacoustic emissions (OAEs) but the absence of normal middle ear reflexes and severely abnormal or completely absent auditory brainstem response (ABRs).
Individuals presenting with this recently recognised hearing loss appear to display sporadic windows of hearing and not. Very few (1 in 14) will go on to develop normal speech and language but with poor speech perception in background noise and in others, no speech perception and therefore language development is possible.
The condition was originally termed
neuropathy
was apparent). In 2008 at a meeting convened at Lake Como in Italy (Guidelines Development
Conference on the Identification and Management
of Infants with Auditory Neuropathy, International
Newborn Hearing Screening Conference, Como, Italy,
June 19–21, 2008), a group of leading authorities on the condition reached a consensus and renamed it as auditory neuropathy spectrum disorder.[3]
