The term APD (Auditory Processing Disorder) is often used loosely by individuals in many different settings to mean many different things. This label is often incorrectly applied to a wide variety of difficulties and disorders. As a result, there are some who question the existence of APD as a distinct diagnostic entity and others who assume that the term APD is applicable to any child or adult who has difficulty listening or understanding spoken language.
An Auditory Processing Disorder (APD) is an auditory deficit that is not the result of other higher-order cognitive, language, or related disorders. Auditory Processing Disorder describes the brain’s inability to recognize and interpret speech sounds in less than optimal conditions. Often these individuals are not recognized as having hearing difficulties because they do not have trouble detecting the presence of sounds or recognizing speech in ideal listening situations. Since they appear to “hear normally”, the difficulties these individuals experience are often presumed to be the result of an attention deficit, a behavior problem, a lack of motivation, or some other cause.
APD is distinctly different from Auditory Comprehension difficulties which refer to difficulty understanding oral language due to language-based difficulties.
