Central Auditory Processing Disorder(CAPD)

Central Auditory Processing Disorder(CAPD)

Slide 2: 

First, what is Central Auditory Processing? It’s the auditory mechanisms and processes responsible for: Sound localization and lateralization Auditory discrimination and pattern recognition Temporal aspects of audition Auditory performance with competing or degraded signals What is CAPD?

What is CAPD? : 

What is CAPD? CAP is what we do with what we hear. CAPD is a deficit of the neural processing of auditory stimuli causing difficulty understanding speech when the signal presented is less than optimal.

What is CAPD? : 

What is CAPD? It’s a brain thing! Abnormal neurophysiologic representation of auditory stimuli. Interhemispheric transfer deficits Imprecise neural firing Atypical hemispheric asymmetries

Manifestations : 

Manifestations Difficulty hearing in noisy environments Responding inconsistently or inappropriately Difficulty directing, sustaining, or dividing attention Easily distracted

Manifestations : 

Manifestations Difficulty taking notes Poor organizational skills Auditory memory deficits Difficulty following multi-step directions Difficulty with reading, spelling, and challenging vocabulary

Diagnosis : 

Diagnosis Etiology: Developmental Acquired Aging Noise Exposure Neurodegenerative ALS, MS, Stroke, TBI, Tumor Prevalence: 2-5% of population and twice as likely to affect males than females

Diagnosis : 

Diagnosis Must be made by an audiologist Auditory Attention Auditory Figure-Ground Binaural Separation/Dichotic Listening Binaural Integration (Fusion) Temporal Sequencing

Sub-profiles : 

Sub-profiles Auditory Decoding Deficit Auditory Integration Deficit Auditory Association Deficit Output-Organization Deficit

Difficulty hearing in noisy environments : 

Difficulty hearing in noisy environments Responding inconsistently or inappropriately Difficulty directing, sustaining, or dividing attention Easily distracted Difficulty taking notes Poor organizational skills Auditory memory deficits Difficulty following multi-step directions Difficulty with reading, spelling, and challenging vocabulary ?

Controversy : 

Controversy ASHA – CAPD is an auditory deficit that is not the result of higher-order cognitive, language, or related disorder. A diagnosis of CAPD alone does not qualify for services. The DSM does not recognize CAPD as a disorder. Insurance generally does not cover services for CAPD.

Language, Speech, and Hearing Services in Schools. Doi:10.1044/0161-1461(2010/10-0013) “… we found no compelling evidence that existing auditory interventions make any significant contributions to auditory, language, and academic outcomes of school-age children diagnosed with APD or language disorder.” Kamhi, A. G. (2010). What SLPs Need to Know about APD. Language, Speech and Hearing Services in Schools. Retrieved from www.asha.org “These theoretical and clinical problems with APD suggest that it may be more appropriate to view auditory deficits as a processing deficit that may occur with common developmental disorders (e.g., SLI, dyslexia, ADHD) rather than a distinct clinical entity.”
