Auditory Processing Disorder (APD)

In the past year I have been going full steam ahead in my continuing education! My latest education has been on Auditory Processing Disorder (APD). I completed the TheraPeeds “Treating Auditory Processing Disorder” course and I loved it, just like I love all of Julia Harper’s courses. I’m starting to sound like a groupie! Haha. But she uses physiology to back up all of her assessments and treatment which I love.

What is APD? Auditory processing is what we do with what we hear. Children with APD do not have a problem with their hearing, they have a problem with how the sound is processed in their brain. “We don’t hear with our ears, we hear with our brain.” Sound information comes into our ears, moves through the outer, middle and inner ear to the lower brainstem, to the upper brainstem, to the midbrain and finally to the cortex. In children with APD somewhere along that pathway the information is not processed as it should be. The type of APD depends on where the breakdown of processing occurs in the brain. Most of the time the breakdown occurs sub-cortically or below the cortex (i.e. lower brainstem, upper brainstem or midbrain).

Audiologists are responsible for diagnosing APD, along with information from SLPs and Educational Psychologists. Then you may be wondering where does an Occupational Therapist come in? Well one of our areas of specialty is sensory processing. Auditory information is sensory information. As OTs we can use our sensorimotor knowledge to help treat APDs.

Treatment for APD focuses on sensorimotor and auditory (sound) activities. Since most of the APDs occur below the level of the cortex we can use sensorimotor activities to ensure that the proper wiring is set up in the brain to allow the messages to get through.

Please contact me with any questions or if you are interested in learning more about how OT can help your child with Auditory Processing Disorder.
