Central Auditory Processing Disorders (CAPD)

These flashcards cover key concepts and information regarding Central Auditory Processing Disorders (CAPD), including definitions, symptoms, diagnosis, treatment strategies, and testing methods.

What is auditory processing?

How the Central Nervous System (CNS) utilizes auditory information.

What percentage of children are estimated to have CAPD?

Estimates range from 0.5% to 10%.

What was the 2016 study's finding regarding CAPD prevalence?

Found a prevalence of 0.2% in the mid-Atlantic region.

What are the three skill sets of auditory processing?

Auditory Discrimination, Temporal Processing, and Binaural Processing.

What is defined as Central Auditory Processing Disorder?

A nervous system-related auditory deficit that interferes with processing auditory information.

What can cause CAPD?

Lesions along the auditory pathway including central structures like retrocochlear areas.

What are common symptoms of CAPD?

Difficulties with understanding speech in noisy environments and localizing sound sources.

What complicates the diagnosis of CAPD?

There are many conditions that can cause difficulty with listening, comprehension, and attention.

At what age does diagnosis for CAPD often begin?

Often around age 7, though some tests can be applied to younger children.

Who are candidates for CAPD testing?

Children to elder adults with complaints of listening difficulties, including those with normal hearing.

What types of tests are used for diagnosing CAPD?

Behavioral test batteries, detailed case histories, and electrophysiologic tests.

What does a battery of tests evaluate?

It is meant to overwork systems to evaluate breakdown and develop performance profiles.

What are examples of auditory behavioral tests?

Dichotic Listening Tests, Auditory Discrimination Tests, and Temporal Processes.

What patterns are assessed from CAPD test results?

Whether issues are with decoding, integration, or specific auditory skills overall.

What indicates a true auditory processing disorder?

If deficits are present in all tests for all tasks.

What are the three major profiles of CAPD?

Decoding deficits, integration deficits, and prosodic deficits.

What characterizes decoding deficits in CAPD?

Inability to extract pitch, loudness, and timing cues with a discrimination-based problem.

What happens in integration deficits?

Deficit in communication between hemispheres, making it hard to synthesize information.

What are prosodic deficits related to?

Inability to process rise and fall in pitch and loudness, showing a right hemisphere issue.

What types of strategies are used for CAPD treatment?

Bottom-Up strategies include auditory training; Top-Down strategies include cognitive interventions.

What professional roles are included in treatment for CAPD?

Audiologists, Speech-language pathologists, psychologists, and family members.

What types of direct treatment strategies exist for CAPD?

One-on-one therapy options, computer-based listening tasks, and home-based therapies.

What characterizes auditory training methods?

Varying stimuli and tasks, graduated difficulty, and providing frequent practice.

What is the status of commercially available sound-based programs?

They are not supported in literature and lack evidence of efficacy.

What environmental modifications can aid individuals with CAPD?

Assistive listening devices and behavioral coaching for better information delivery.

What compensatory strategies can help those with CAPD?

Strengthening language skills, problem-solving abilities, memory, and self-advocacy.
