Auditory Processing Disorder (APD) is a diagnosis used to describe difficulties experienced with the processing of
sound despite the ear being able to detect sounds at normal levels. Humans hear when energy that we recognize as
sound travels through the ear and is changed into electrical information that can be interpreted by the brain. APD is the
inability to notice, compare and distinguish the distinct and separate sounds in words. Auditory processing disorder
(APD) is not a hearing impairment but the inability to process what is heard.
The term auditory processing disorder (APD) means that something is adversely affecting the processing or
interpretation of the information. Hearing starts with a complex set of actions within the outer, middle and inner ear.
These actions send the sounds to the brain that interprets them so the individual can understand. This set of actions
may be defined as listening and carries the medical term auditory processing. APD can negatively affect various skills
such as academics, communication and social success. The child may have problems paying attention to auditory input,
distinguishing sounds and remembering auditory information. All theses can affect a child’s ability to learn and cope
well in academics.
APD goes by many other names. Sometimes it is referred to as central auditory processing disorder (CAPD). Other
common names are auditory perception problem, auditory comprehension deficit, central auditory dysfunction, central
deafness, and so-called "word deafness”. Human communication relies on taking in perplexing and continuous
information from the outside world through the senses, such as hearing and interpreting that information in a
meaningful way. Communication also requires certain mental abilities, such as attention and memory. Even though your
child seems to hear normally, he or she may have difficulty using the sounds of speech and language.
Possible Causes
If an individual's auditory processing is functioning well but there is no understanding of the sounds that are heard, the
individual may have an APD. In some children with APD there may be tiny differences in the way that neurons (brain
cells) are joined together, or send messages to each other. This may make it hard for sounds to be passed on to the
areas of the brain that aid the understanding of language. It is possible such brain cell differences may cause APD.
Scientists still do not understand exactly how all of these processes work to interact or how they malfunction in cases
of communication disorders.
APD is an auditory deficit that is not related with cognitive and language skills. In some children, auditory processing
difficulty may be associated with conditions such as
dyslexia, attention deficit disorder, autism, autism spectrum disorder, specific language impairment, pervasive
development disorder or developmental delay. Sometimes this term has been misinterpreted in children who have no
hearing or language disorder but have challenges learning. A diagnosis of all these disorders may be helpful in
understanding the cause to behavioral problems.
Signs and Symptoms
• Have difficulty processing and remembering language-related tasks but may have no trouble interpreting or
recalling non-verbal environmental sounds, music, etc.
• Difficulty understanding spoken messages and/or remembering instructions
• Struggles with expressing themselves clearly and using speech
• May process thoughts and ideas slowly and have difficulty explaining them
• Have trouble paying attention to and remembering information
• Often is distracted by background sounds/noises
• Have behavior problems
• May misinterpret or find it hard remembering oral directions
• Has difficulty comprehending complex sentence structure or rapid speech
• Ignores the speaker especially if preoccupied by something
• Have difficulty with reading, comprehension, spelling, and vocabulary
• Need more time to process information
• History of multiple ear infections
Children with auditory processing difficulty overall have normal hearing and intelligence. It is thought that up to 10% of
children may have some level of APD. There are a number of tests to diagnose APD. APD cannot be diagnosed from a
symptoms checklist. No matter how many symptoms of APD a child may have, only careful and accurate diagnostics
can determine the underlying cause.
Diagnosing APD
A multidisciplinary team is crucial to fully assess and understand the group of problems exhibited by children with
APD. Thus, a teacher or educational diagnostician may shed light on academic difficulties; a psychologist may evaluate
cognitive functioning in a variety of different areas; a speech-language pathologist may evaluate written and oral
language, speech, and other related capabilities. Some of these professionals may use test tools that include the terms
“auditory processing” or “auditory perception” in their evaluation, and may even suggest that a child exhibits an
“auditory processing disorder.”
It is important for parents to know that, however beneficial the information from the multidisciplinary team is in
understanding the child’s overall areas of strength and weakness, none of the test tools used by these professionals are
diagnostic tools for APD, and the actual diagnosis of APD must be made by an audiologist.
To diagnose APD, the audiologist will administer a series of tests in a sound-treated room. These tests require listeners
to attend to a variety of signals and to respond to them via repetition. Other tests that measure the auditory system’s
physiologic responses to sound may also be administered. Most of the tests of APD require that a child be at least 7 or
8 years of age because the variability in brain function is limited in younger children that test interpretation may not be
possible.
Once a diagnosis of APD is made, the nature of the disorder is determined. There are many types of auditory
processing deficits and, because each child is an individual, APD may manifest itself in a variety of ways. It is
necessary to determine the type of auditory deficit a given child exhibits so that individualized management and
treatment activities may be recommended that address his or her specific areas of difficulty.
Treatment of APD
Treatment of APD focuses on three fundamental areas: changing the learning or communication environment,
encouraging higher skills to help compensate for the disorder, and intervention of the auditory deficit itself. The primary
purpose of environmental modifications is to improve access to auditory presented information. Suggestions may
include use of electronic devices that assist listening, teacher-oriented suggestions to improve delivery of information,
and other methods of altering the learning environment so that the child with APD can focus his or her attention on the
message.
Compensatory strategies usually consist of suggestions for assisting listeners in strengthening central resources
(language, problem-solving, memory, attention, and other cognitive skills) so that they can be used to help overcome
the auditory disorder. In addition, many compensatory strategy approaches teach children with APD to take
responsibility for their own listening success or failure and to be an active participant in daily listening activities through
a variety of active listening and problem-solving techniques.
Finally, direct treatment of APD seeks to resolve the disorder, itself. There exist a wide variety of treatment activities to
address specific auditory deficits. Some may be computer-assisted; others may include one-on-one training with a
therapist. Sometimes home-based programs are appropriate whereas others may require children to attend therapy
sessions in school or at a local clinic. The type, frequency, and intensity of therapy, like all aspects of APD
intervention, should be highly individualized and programmed for the specific type of auditory disorder that is present.
With appropriate intervention, all children with APD can learn to become active participants in their own listening,
learning, and communication success rather than being helpless to the disorder.
