Test and Assessments for Auditory Processing Disorder (APD)

APD does not feature in mainstream diagnostic classifications such as the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). APD is not a coherent syndrome with clear diagnostic criteria. Rather, it is a label applied when a person has difficulties in recognizing and interpreting sounds that are not due to peripheral hearing loss.

As such, test and assessments for this condition can be difficult and tricky. This is because the symptoms associated with this disorder overlaps with many symptoms of other disorders, such as ADHD, Dyslexia, Asperger’s and etc.

Essentially, our brain is the center that controls for our thinking, reasoning, learning, language, behavior and emotions. For problems associate with the brain, we should look into the brain for answers. As Auditory processing disorder is recognized as a brain problem rather than a hearing problem, it makes alot of sense to look into the brain for answers.

At Spectrum Learning, we do not focus on symptoms but the causes for the symptoms. We use QEEG Brain Mapping to look at what is going on in the brain while the child is attempting academic tasks, including listening comprehension and reading. With the QEEG analysis, we can identify regions of the brain that shut down or which sites are not activated while on a listening comprehension task. We also investigate whether there are biological factors that may contribute to or aggravate the condition.

Brain Based Assessments for Auditory Processing Disorders:

For this disorder, we find that it is best to look at what is going on in the brain while the child is on an auditory task, such as Listening Comprehension. Below are some examples of the QEEG of children with APD.

A) This QEEG profile is also featured in the Dyslexic page. This child is diagnosed with dyslexia and also has auditory processing problems.

B) The QEEG on the left is another example of auditory processing along side a diagnosis of dyslexia.

From these QEEG brain mappings, we can see specific areas of shut down while the child is on listening tasks. With this information, we can design a specific training using neurofeedback to train the affected areas to increase in neuronal activities instead of reduction while on listening tasks. We find that this rhelps the child to overcome the auditory processing problem quickly.

The above again reinforces the notion that problems associate with the brain should have a brain based approach.

Biological Factors:

There are many biological factors that can cause a child to develop auditory processing problems. We find that it is very common for children with learning or developmental problems to have exposure to toxic elements.

The diagram on the left shows a child with auditory processing problems. He is has symptoms of ADHD.

Children with exposure to toxic elements such as this case will take a long time to respond to any intervention if the toxic exposure is not removed. For this case, a detoxification program is crucial for intervention to show significant results.

Nutritional imbalance/deficiencies can also cause or aggravate the condition. The diagram on the left shows a boy with Zinc deficiency and excess Potassium. Such imbalance can lead to learning difficulties, including auditory processing difficulties.

Brain Mapping - QEEG

Brain Mapping (QEEG) is a safe and non-invasive brain imaging technique. It measures brain waves (EEG) that the brain sends out from at least 19 locations simultaneously.

Careful analysis of these brains waves (EEG) can reveal information on how one is using his/her brain. It can also tell us the maturity of different parts of the brain. It is often used to investigate if there are any hidden seizures.

Finding the Causes

Most clinicians do not bother about the causes as diagnosis is based on behavioral symptoms …   

At Spectrum Learning, we have been investigating the possible causes …
