However, if the primary problem lies beyond the auditory cortex, such as cognitive processing, the diagnosis of APD is trumped by a more prominent differential diagnosis-including specific language impairment, dyslexia, attention deficit/hyperactivity disorder (AD/HD), intellectual impairment, and perhaps more.įurther, the lack of standard metrics used to measure APD is problematic. Ideally, the diagnosis of APD should indicate a problem processing auditory information within the traditionally recognized central auditory nervous system (CANS). That is, they may represent primary (ie, global) problems manifesting as APD, or a multitude of secondary problems also manifesting as APD. These signs/symptoms are often attributed to APD, but clearly they are not exclusive to APD. The most common signs and symptoms attributed to APD include listening difficulties without hearing loss, inattention, daydreaming, less-than-expected academic achievement, and more. Indeed, despite almost a century of analysis and more than 1.3 million citations on Google (January 2016), APDs remain universally ill-defined and poorly understood. Despite a well-attended history, there is little agreement on the definition, diagnosis or treatment of APDs in 2016. The definition, etiology, signs, symptoms, treatment, and outcomes of auditory processing (AP) and Auditory Processing Disorders (APDs) have been reasoned and debated for more than 80 years. We look forward to working with you.Inside Clinical Research | April 2016 Hearing Reviewīy Douglas L. If you suspect that you or your children has an auditory processing disorder, please contact our office to schedule a consultation. About 10% will require a second round of therapy.Working one-to-one with a professional on auditory training can develop the skills and strategies specific to the child’s deficit. Most commercially available programs only provide practice related to general auditory processing skills. Therefore, it is a deficit specific therapy, which allows extensive training in the child’s weak areas. The therapy associated with this model works directly on those areas found to be related to the diagnosed APD categories. It is estimated that 20 percent of the school age population has APD. ![]() We identify the child’s specific deficits which are associated with specific academic and communication difficulties.įor a trained doctor of audiology (Au.D.) an Auditory Processing Disorder is not very difficult to identify, classify, or even to remediate. This program relies on the anatomy and physiology of the central auditory nervous system regions. Most commercially available programs provide practice related to general auditory processing skills, whereas the Buffalo Model’s treatment targets the specific areas of weakness identified in the APD testing. Integration The ability for the left and right hemispheres of the brain to communicate.Organization The ability to store orally presented information in the brain.Tolerance-Fading Memory The ability to understand speech while in competing noise and the necessary short-term memory capacity to do so.Decoding The ability to quickly and accurately process phonemes, or, the sounds of speech.The tests measure a person’s performance in four categories: We assess patients (ages 7 years and older) on the degree to which they deviate from the norms on several listening tests. How is an Auditory Processing Disorder diagnosed?Īt Aberdeen Audiology, we primarily use the Buffalo Model for diagnosing and treating auditory processing issues, which was developed by Jack Katz, Ph.D. Difficulty following a string of directions delivered orally.Difficulty with reading, spelling, reading comprehension.A consistent delay in response to a question or instructions.Problems attending to different information presented to opposite ears.Problems successfully combining auditory and visual information.Difficulty organizing sounds in a proper sequence.Difficulty remembering auditory information.Difficulty understanding speech in the presence of background noise. ![]() ![]() The ear detects and transmits sound to the brain normally, but when the orally presented information goes to the brain, the child or adult has problems interpreting or understanding it accurately or efficiently. Despite having normal hearing sensitivity, people with auditory processing disorders (APD) have difficulty processing and interpreting auditory information.
