Diagnosis and management of Auditory Processing Disorder
Approximately 5-7 % of children meet the diagnostic criteria for the neuro-developmental disorder termed Auditory Processing Disorder (APD). These same children will often display significant literacy development difficulties. Adults also experience auditory procesisng deficits, with incidence increasing wth age.
The development and underlying associations of auditory processing skills require better understanding, and is a primary focus of this research team. Recent research has shown significant link exists between cognitive abilities and performance on specific auditory processing tasks (Tomlin et al., 2015). Evidence supporting delays in central auditory nervous development in children with APD has also recently been published (Tomlin & Rance, 2015), which would support an overall neuro-maturational delay as an underlying cause of Auditory Processing, cognitive and reading deficits.
How to ameliorate this disorder and optimize listening and/or educational outcomes is still to be determined. The second aim of this team is to evaluate the efficacy of various remediation approaches for their ability to target the neuro-plasticity of the central auditory nervous system and improve long-term auditory processing, literacy and listening outcomes in children and adults)diagnosed with APD. Determining the efficacy of available rehabilitation approaches for the amelioration of auditory processing deficits will provide clinical guidelines for the management of this disorder, and further insight into the mechanisms and pathways underlying auditory porcessing ability.
