It is broadly recognised that the identification and management of CAPD is a multidisciplinary approach. Audiologists provide pivotal information for initial or differential diagnosis and assessment for auditory processing disorders. This may involve other health professionals such as speech pathologists, psychologists, and paediatricians if we are providing rehabilitation for children.
A comprehensive test battery is designed to minimise language and cognitive components so a more reliable picture of auditory processing skills can be obtained. Audiologists look at how auditory information is used. This sometimes involves listening to speech in noise, listening for different beeps, or recalling sets of information. Occasionally this can involve electrophysiological testing; where we set up electrodes and look at the brains neural response to stimulus.
Testing typically takes up to 1.5 hours to complete and can be quiet demanding on children. Once results are obtained, a multi-disciplinary approach is taken to provide guidance for effective remediation strategies and rule out any other factors such as language impairment issues, cognitive problems, or attention difficulties.
Our test battery includes a range of assessments identifying how well the auditory system performs certain tasks. For example, one test is targeted towards how well someone can focus on a speaker when there are other noises distracting them from different spatial planes. Another investigates how well they can remember and manipulate verbal information. Other tests included look at binaural integration (how well we use information coming from different ears at the same time).
The results from these tests can lead to targeted potential remediation/treatment in the form of training, learning software or other devices for the classroom setting.
Our standard CAP test battery includes the following tests:
In some cases we may elect to do additional tests should they be required. Your ENT or GP may also have requested additional tests to further exclude nerve issues from central auditory processing issues.
We would only do these tests if requested or if there was concerns with Auditory Dyssynchrony for instance. If there was abnormal pattern of results in the standard CAP test battery this could be suggested (eg poor speech reception scores in the presence of near normal hearing)
These assessments are:
While they may be a particularly adept child to the parent or the individual enquiring, all the normative data (the information that we compare the child’s results against saying if this is normal or not) is based on age. There is no normative data for those under the age of 7 because of the unreliability in testing.
Testing can also be quite draining for children and requires a significant amount of attention. Most children under this age are unable to maintain focus and/or completely comprehend the tests accurately. This means tests would not provide reliable results.
