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 community, individuals with APD and their families, and are proud to have the parent of a child with APD as an advisor 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 BSA APD Position Statement and Practice Guidance Document, published in 2011, has served a catalyst for moving the field of APD forward and fostering international collaboration.
The above 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 the AAA hosted a further successful APD Conference, again as part of the AAA Conference, in Orlando in 2014.
Since 2011, and 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. We are currently updating our own documents.
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:
- Cases presenting in childhood with normal hearing (i.e. normal audiometry) and no other known aetiology or potential risk factors. Some of these people may retain their APD into adulthood.
- Acquired APD: Cases associated with a known post-natal event (e.g. neurological trauma, infection) that could plausibly explain the APD.
- Secondary APD: Cases where APD occurs in the presence, or as a result, of peripheral hearing impairment. This includes transient hearing impairment after its resolution (e.g. glue ear or surgically corrected otosclerosis).
