This could be either a permanent hearing loss or a temporary or fluctuating hearing problem like glue ear or regular ear infections. This type of processing difficulty is associated with a hearing loss. brain lesions, trauma, illness, noise damage or general aging) Secondary APD These listening and processing difficulties are associated with a known medical or environmental cause (e.g.
Patients often continue to have the same types of difficulties from childhood into and throughout adulthood. This type of APD presents as a listening difficulty but with normal hearing tests and no other known contributing causes or risk factors other than a family history of developmental communication and related disorders.
There are three different categories of auditory processing disorder (APD): Developmental APD What are the different categories of Auditory Processing Disorder? These difficulties affect patients of all ages. This often leads to a variety of difficulties and often almost mimics a hearing loss. What is an Auditory Processing Disorder?Īuditory processing disorder is a difficulty for the brain to turn acoustic sounds into usable information. When we perform a standard hearing test, we check whether the ears are detecting sounds and can often disregard significant listening difficulties due to a hearing test suggesting normal hearing levels. This process is called ‘auditory processing’. When we listen, we don’t only rely on our ears to detect sound, but also on our brain to use the acoustic clues in the environment, recognise and interpret these to make sense of the information our ears have received. In this blog, we will explain these Auditory Processing Disorders and look at some problems that APD can cause. These include, Developmental APD, Acquired APD and Secondary APD. There are many different categories of Auditory Processing Disorder (APD).
