Auditory Processing Disorder and Dyslexia

Why do most dyslexic children have APD symptoms?

Many parents express frustration that the symptoms of dyslexia appear indistinguishable from auditory processing disorder (APD) or they try to distinguish between auditory processing disorder and dyslexia using the misconception that dyslexia is about letter reversal only.

The choice in fact is not between auditory processing disorder and dyslexia. In most cases they exist together because one causes the other.

This is because for most dyslexic children, their reading difficulty stems from an underlying language processing difficulty. They switch their b’s and d’s, not because they see them the same, but rather because they hear them the same.

Auditory Processing Disorder And Dyslexia Have The Same Source Problem

Reading is a language skill — it requires phonological awareness to be able to break words down into individual sounds and then recognize them in text form. Reading also requires vocabulary and other language knowledge.

Children with auditory processing difficulties tend to have weak phonological awareness skills and struggle with language familiarity — grammar, syntax, vocabulary, articulation — making them at risk readers, often leading to a dyslexia diagnosis.

In short, auditory processing disorder and dyslexia are related in a sequential way. Weak auditory processing skills cause dyslexia symptoms. In fact, one of the best ways clues of dyslexia, a way to distinguish between a normal reading difficulty and dyslexia — a more stubborn reading delay that won’t like resolve itself — is to look for signs of the auditory processing disorder at the source of the dyslexia issue.

How To Help Auditory Processing Disorder & Dyslexia Symptoms

Our recommendation is to start at the source of the problem, by strengthening auditory processing. Gemm Learning uses Fast ForWord software, online with remote oversight. By improving processing efficiency and related working memory and attention skills we expect to:

  • Improve reading fluency
  • Improve reading comprehension, by making decoding efficient
  • Boost language skills, receptive and expressive

Outcomes do vary, but auditory processing disorder and dyslexia are where we have success. Our software-based treatment was founded on the idea that: (1) reading is an auditory processing issue, and (2) the brain can rewire to overcome auditory processing disorder and related dyslexia symptoms.
