Who are we?
The APD SIG, was established in 2003 and is the first BSA SIG. Our steering committee represents a broad range of professional disciplines, and includes leading researchers and clinicians in the field. We foster strong links with the community and individuals with APD as well as their families. We invite both professionals and members of the public to serve as advisors to our SIG.
What is our aim?
The aim our APD SIG is to promote a high standard of research and evidence-based care and encourage international and interdisciplinary collaboration.
Our APD SIG has been at the forefront of international developments in recent years. The new Position Statement and Practice Guidance APD 2018 was published in February 2018. Please note this document updates rather than replaces the existing 2011 documents. These documents should be read together.
The above 2011 documents culminated in the publication a BSA ‘white paper’ on Developmental APD, one of the three types of APD (Moore et al, 2013). The BSA ‘white paper’, a discussion document published in the International Journal of Audiology, outlined the thinking of the BSA at that time and international commentaries from other research groups working on APD. The BSA APD Special Interest Group (SIG) initiated and collaborated with the American Academy of Audiology (AAA) to present a well-received APD Conference as part of the AAA Conference held in Boston in 2012. This conference drew significant international interest and attendance, leading to productive debate and collaboration. Due to its popularity further global APD Conferences, were held, again as part of the AAA Conference, in 2014 and 2016.
Following our call for evidence based practice there has been a surge in the number of randomised control studies published and clearer report of subject selection criteria. Several groups around the world have now issued APD statements, guidelines and/or white papers. There is growing recognition of the need to assess real-world listening ability and the importance of cognitive factors. The high co-occurrence of APD with other developmental disorders in children, including specific language impairment, dyslexia and autistic spectrum disorder, is now more widely recognised.
What is an Auditory Processing Disorder?
APD is characterised by poor perception of sounds, has its origins in impaired neural function, and impacts on everyday life primarily through a reduced ability to listen, and so respond appropriately to sounds. There are 3 categories of APD:
- Developmental APD: Cases presenting in childhood with listening difficulties, but with normal audiometric hearing and no other known aetiology or potential risk factors other than a family history of developmental communication and related disorders. These individuals may retain APD into adulthood
- Acquired APD: Cases associated with ageing or a known medical or environmental event (e.g. brain lesion)
- Secondary APD: Cases where APD occurs in the presence, or as a result of either transient or permanent peripheral hearing impairment
