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 disorderĪuditory Processing Disorder can be either neurologically based, or the result of head injury or ear infections. The condition was originally termed auditory neuropathy (AN) and in 2001 as Auditory Neuropathy / Auditory Dys-synchrony (AN/AD) (to include those cases where no true neuropathy was apparent). 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. Individuals presenting with this recently recognised hearing loss appear to display sporadic windows of hearing and not. It is thought that these difficulties arise from dysfunction in the central nervous system.’ Auditory NeuropathyĪuditory 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). However, they cannot process the information they hear in the same way as others do, which leads to difficulties in recognising and interpreting sounds, especially the sounds composing speech. Individuals with APD usually have normal structure and function of the outer, middle, and inner ear (peripheral hearing). ‘Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome or auditory disability with normal hearing ( ADN), is an umbrella term for a variety of disorders that affect the way the brain processes auditory information. Affecting around five percent of young children, this condition prevents their young ears and brain to fully coordinate because of interference so they cannot process what they hear adequately. It is a disorder that delays or disrupts the processing of auditory information. In its very broadest sense, Auditory Processing Disorder refers to how the central nervous system uses auditory information. “Auditory Processing Disorders” was first published in January 2005 by The American Speech-Language-Hearing Association (ASHA).
