Divergent perspectives among professionals reflect ongoing debate regarding how to define, assess, and treat auditory processing disorder.ĭifferent viewpoints exist for a number of reasons, including the heterogeneity of symptoms, variations in the definition, the lack of a reference standard for diagnosis, the relationship between auditory perceptual deficits and language disorders, and the particular treatment approach(es) that follow from the diagnosis of CAPD (Kamhi, 2011 Moore, Rosen, Bamiou, Campbell, & Sirimanna, 2013 Vermiglio, 2014). Professionals have adopted varying perspectives on the interpretation of CAPD (Cacace & McFarland, 2008 DeBonis & Moncrieff, 2008 De Wit et al., 2016 Friberg & McNamara, 2010 Jerger, 1998 McFarland & Cacace, 2006 Rees, 1973, 1981). CAPD is not due to peripheral hearing loss, which includes conductive hearing loss (i.e., outer or middle ear), sensorineural hearing loss at the level of the cochlea or auditory nerve, including auditory neuropathy and synaptopathy (i.e., hidden hearing loss).CAPD may coexist with other disorders (e.g., attention-deficit/hyperactivity disorder, language impairment, and learning disability).CAPD may lead to or be associated with difficulties in higher order language, learning, and communication functions.Although sometimes difficult, careful differential diagnosis is important to the process of treatment planning. Terms include, but are not limited to, "auditory processing disorder," "(central) auditory processing disorder," "language processing disorder," and "auditory information processing disorder."ĪSHA uses the term Central Auditory Processing Disorder (CAPD) to refer to deficits in the neural processing of auditory information in the CANS not due to higher order language or cognition, as demonstrated by poor performance in one or more of the skills listed above (ASHA, 2005). Terms used to describe a processing disorder may vary based on the perspective of the professional describing the problem. Auditory performance with competing or degraded acoustic signals (including dichotic listening ASHA, 2005)Ĭentral Auditory Processing Disorder (CAPD).temporal resolution (e.g., temporal gap detection).Temporal aspects of audition, including.These mechanisms underlie the following skills: Medwetsky (2011) provides in-depth information on this topic.ĬAP consists of mechanisms that preserve, refine, analyze, modify, organize, and interpret information from the auditory periphery. Knowledge of the neuroanatomy and physiology of the central auditory nervous system is essential for understanding and interpreting underlying processes and deficits. Central Auditory Processing (CAP)Ĭentral auditory processing (CAP)-also seen in the literature as (central) auditory processing or auditory processing-is the perceptual processing of auditory information in the central auditory nervous system (CANS) and the neurobiological activity that underlies that processing and gives rise to electrophysiologic auditory potentials (American Speech-Language-Hearing Association, 2005). See the Central Auditory Processing Disorder Evidence Map for pertinent scientific evidence, expert opinion, and client/caregiver perspective. Content is relevant to both developmental and acquired CAPD. To find an audiologist near you, visit ProFind.The scope of this page is central auditory processing disorder (CAPD) in children and adults. Learn more by reading the article Understanding Auditory Processing Disorders in Children by Teri James Bellis, PhD, CCC-A. This may include using active listening and writing down what they hear. Teaching your child ways to listen better.Or, your child may use a listening device or FM system. This may include changing their classroom so they can hear better, called classroom acoustics. Finding ways to help your child hear speech.Your child may have to learn to hear sounds and focus on what others say. Your child may need treatment if they have APD. An SLP can test your child’s speech and language. To find out if your child has APD, your child may see a team that includes a:Īn audiologist will choose tests based on your child’s age and the types of problems they have. Children with APD can have trouble in school and at home. It is often confused with attention, language, or learning problems. It can be hard to know if your child has APD. They may not follow directions, or they may give the wrong answers to questions. If they do not have a hearing loss, it could be APD.Ĭhildren with APD may act like they have a hearing loss. Audiologists can test for APD.ĭoes your child seem to have trouble hearing? Do they understand what others say to them? You should first have your child’s hearing tested. They may have an auditory processing disorder, or APD. Some children have trouble hearing but do not have a hearing loss.
