Auditory Processing Disorder (APD) is a complex problem that affects the way the brain processes auditory information. Individuals with APD usually have normal structure and function of the outer, middle and inner ear. However, they cannot process the information they hear in the same way as others, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech. It is thought that these difficulties arise from dysfunction in the central nervous system (i.e., brain). APD has been referred to as “dyslexia for the ears” because it causes a mismatch between peripheral hearing loss (i.e., normal hearing) and the ability to interpret or discriminate sounds.
