tHe nature of Central auditory ProCessing disorder

Historically, there has been much debate among professionals in many disciplines regarding the nature of central auditory processing disorder (CAPD) and the best means of diagnosing and treating it. In recent years, professionals in the fields of audiology, speech-language pathology, education, and related disciplines have witnessed a dramatic upsurge in interest regarding CAPD in both children and adults, and the demand for central auditory services has surged. As a result, it has become even more crucial that clinicians understand the fundamental principles underlying central auditory processing and its disorders. The previous chapters in this volume have discussed the scientific bases of central auditory processing, both neu-robiological and psychoacoustic, that inform our current conceptualization of CAPD, as well as etiologic factors that may underlie the disorder. Because an understanding of the fundamental nature of any disorder is critical to appropriate diagnosis and intervention, this chapter discusses key factors affecting central auditory processing and the current definition of CAPD, including how the disorder may lead to or be associated with difficulties in learning, language, communication , and related function. The topic of subprofiles of CAPD in children and adults also are explored, as are areas for future research in central auditory diagnosis and treatment.
