APD Diagnosis: Does APD Exist?
![Page 4: APD : Evaluation and Management - ncshla.org Evaluation and Management...What is APD? APD is a deficit in one or more of the auditory mechanisms which underlie tasks such as: localization](https://reader031.vdocuments.mx/reader031/viewer/2022022808/5d61bafc88c99359548b9115/html5/thumbnails/4.jpg)
What is APD?
APD is a deficit in one or more of the
auditory mechanisms which underlie
tasks such as:
localization and lateralization,
discrimination,
temporal processing
performance under conditions
of degraded and/or competing
acoustic signals.
APD may occur alone or may
coexist with higher-level, global
disorders which impact general
processing abilities, including
attention- and language-related
disorders (ASHA, 1996).
![Page 5: APD : Evaluation and Management - ncshla.org Evaluation and Management...What is APD? APD is a deficit in one or more of the auditory mechanisms which underlie tasks such as: localization](https://reader031.vdocuments.mx/reader031/viewer/2022022808/5d61bafc88c99359548b9115/html5/thumbnails/5.jpg)
ASHA/AAA
ASHA 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).
AAA: (C)APD refers to difficulties in the
perceptual processing of auditory information
in the central nervous system and the
neurobiologic activity that underlies that
processing and gives rise to the
electrophysiologic auditory potentials.(AAA,
2010)
![Page 6: APD : Evaluation and Management - ncshla.org Evaluation and Management...What is APD?

Does APD Exist?
Individuals with APD have difficulty hearing that is not explained by a peripheral hearing loss.
These individuals exhibit specific patterns of dysfunction on tests of central auditory function that mirror those of known pathologies involving the CANS and nothing else.
Growing body of evidence obtained from new technological measures of auditory processing is demonstrating that representation of sound in the higher brainstem or brain pathways of many of these individuals is different from that of other, non-disordered individuals.

CAPD is listed in the ICD-10 under ear diseases (code H93.25) for both
acquired and congenital CAPD, which confirms the physiological nature of
this disorder and supports the medical necessity for care.
US Ninth District Circuit Court precedent-setting ruling13 that children with
CAPD are entitled to receive services in schools under the category of “other
health impaired” (OHI). Also reiterated that audiologists are the
professionals qualified to diagnose CAPD, the legitimacy of CAPD diagnosis
for children is extremely well -supported and established for a population
who has long been underserved in our schools, as well as for adults seeking
help for CAPD.

ONLY the audiologist diagnoses an APD.
CAPD is an auditory deficit; therefore, the
audiologist is the professional who makes the
diagnosis (ASHA, 2005)
The diagnosis should be made by audiologists
who have been properly educated and trained in
the area of (C)APD, including the administration
and interpretation of these tests and
procedures. Acoustic control of both the test
stimuli and the testing environment is essential,
and at times special equipment is necessary to
diagnose (C)APD. (AAA, 2010)

Diagnoses written, reading, and verbal language processing and can SCREEN for APD referral to audiology
SLPs diagnose cognitive-communication and language-related disorders (including language processing disorders) that may co-occur with CAPD.
Differentiating between language and phonological processing disorders and CAPD requires collaboration between audiologists and SLPs.

Subsequent to a central auditory evaluation, a speech-language pathologist can explore the possible impact of auditory processing-related deficits on specific aspects of language processing. An initial speech-language evaluation may suggest underlying central auditory processing deficits, with subsequent referral for a central auditory processing evaluation.
Speech-language pathologists also are best prepared to provide a number of the interventions elaborated in the preceding section of these guidelines (e.g., central resources training). AAA, 2010

Supporting role in assessment and intervention for
(C)APD. In instances where a sensory integration
disorder (also known as regulatory-sensory processing
disorder) or a motor-sequencing deficit has been
identified, the audiologist may confer with the
occupational therapist to determine potential
interactions between these purportedly pansensory
deficits and a (C)APD. AAA 2010

If you are not isolating the auditory system you
are not testing APD; you are only testing
language skills in a sound field environment,
without isolating temporal conditions,
background noise, or individual ear
performance.

Referral is made, APD is diagnosed….

What type of APD is diagnosed?
A diagnosis of CAPD is enabled
only when performance on > 2
tests is abnormal AND the pattern
of findings is consistent with
underlying neuroscience tenets
(ASHA, 2005)
Lack of a pattern (e.g., poor
performance on all measures)
argues for more global or
motivational deficit, not CAPD

Basic
Principles of
Treatment
Strategies
Intervention should arise logically from specific auditory deficits and functional/behavioral sequelae.
Results of diagnostic testing, along with other information, provide the framework.
The key to effective treatment is accurate diagnosis
![Page 25: APD : Evaluation and Management - ncshla.org Evaluation and Management...What is APD? APD is a deficit in one or more of the auditory mechanisms which underlie tasks such as: localization](https://reader031.vdocuments.mx/reader031/viewer/2022022808/5d61bafc88c99359548b9115/html5/thumbnails/25.jpg)
Intervention should:
be a multidisciplinary endeavor, and should address both bottom-up and top-down skills
1
be individualized and deficit-specific (the diagnosis drives the treatment)
2
focus on improving access to auditory information, strengthening central resources, and remediating the auditory deficit

Step 1
Identify the auditory
deficits using results of
behavioral central
auditory testing and
other data to determine
specific areas of
auditory dysfunction
that need to be targeted
![Page 27: APD : Evaluation and Management - ncshla.org Evaluation and Management...What is APD? APD is a deficit in one or more of the auditory mechanisms which underlie tasks such as: localization](https://reader031.vdocuments.mx/reader031/viewer/2022022808/5d61bafc88c99359548b9115/html5/thumbnails/27.jpg)
Step 2
Relate auditory deficits to
language, learning,
communication, and
related sequelae for
development of
ecologically valid
treatment plan
Functional Deficit Profiling
(Ex: Bellis-Ferre model)

Step 3
Select appropriate
treatment and
