![]() ![]() The incidence of the disorder has been widely speculated but is not fully understood. Amanda Ortmann, in Handbook of Clinical Neurophysiology, 2013 11.4.1 Populations that could present with auditory processing disorderĪuditory processing disorder (APD) can be either genetic or acquired and occurs in both children and adults. The chapter culminates with a case study illustrating pre- and posttreatment behavioral and electrophysiologic diagnostic findings.ĭeborah Moncrieff. This chapter provides an overview of current definitions and conceptualizations, methods of diagnosis of, and intervention for, CAPD. Intervention recommendations for CAPD diagnosis are based on the demonstrated auditory processing deficits and related listening and related complaints. Administration of behavioral and/or electrophysiologic audiologic tests that have been shown to be sensitive and specific to dysfunction of the CANS is critical for a proper diagnosis of CAPD, in addition to assessments and collaboration with a multidisciplinary team. ![]() Although it is recognized that central auditory dysfunction may coexist with other disorders, CAPD is conceptualized as a sensory-based auditory disorder. CAPD is a neurobiologic deficit in the central auditory nervous system (CANS) that affects those mechanisms that underlie fundamental auditory perception, including localization and lateralization discrimination of speech and non-speech sounds auditory pattern recognition temporal aspects of audition, including integration, resolution, ordering, and masking and auditory performance with competing and/or degraded acoustic signals ( American Speech-Language-Hearing Association, 2005a, b). Bellis, in Handbook of Clinical Neurology, 2015 AbstractĬentral auditory processing disorders (CAPD) can affect children and adults of all ages due to a wide variety of causes.
