If a child has trouble comprehending directions, mixes up words with similar pronunciations, or seems disoriented in loud environments, parents might presume that a hearing problem is to blame. However, in some instances, the problem might not lie with the ears themselves, but rather with a condition called auditory processing disorder (APD), which impacts the way the brain deals with sound.
Even though hearing loss and Auditory Processing Disorder (APD) often present with comparable signs, they are distinct conditions that necessitate unique assessments and interventions. In this article, we will explore the key distinctions to help you give your child the support they need.
Understanding Hearing Loss: A Definition.
Hearing loss refers to a decreased ability to detect sound, usually a result of issues in the outer, middle, or inner ear.
There are three primary kinds:
- Conductive hearing loss: Triggered by blockages or damage in the outer or middle ear (including ear infections or wax accumulation)
- Sensorineural hearing loss: Consists of damage to the inner ear or the auditory nerve, often caused by aging, noise exposure, or genetics
- Combination hearing loss: A blend of both outer/middle ear and inner ear issues
Doctors normally diagnose patients by carrying out tests including audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. When a child experiences hearing loss, the issue is with their capacity to perceive sound at all.
What Is Auditory Processing Disorder?
In contrast, APD is not related to hearing difficulties, but instead a neurological issue that impacts the brain’s ability to process and comprehend auditory information. Children with Auditory Processing Disorder might have normal hearing, but they struggle to decipher and comprehend the sounds they hear.
It’s frequently described as “hearing but not understanding.”
Common obstacles faced in everyday scenarios:
- Difficulty following multi-step verbal directions
- Difficulty distinguishing similar sounds or words
- Having difficulty focusing in noisy settings (such as schools or busy eateries)
- Having trouble recognizing humor, irony, or expressions that aren’t meant to be taken literally
A standard hearing exam may indicate no issues because the ears are functioning normally. But that doesn’t mean all is working as it should. In APD, the breakdown occurs after sound is sensed, during processing in the central auditory nervous system.
Differentiating Between Testing and Diagnosis
In order to diagnose hearing loss, audiologists use traditional hearing exams that measure sound detection. Diagnosing APD, however, calls for specialized testing that exceeds detecting sound.
Evaluations often involve a multidisciplinary team, including:
- A hearing specialist to assess how the brain senses sound
- A speech-language pathologist to assess language comprehension and communication
- A psychologist should be consulted to determine any hidden attention or learning conditions that might imitate the symptoms of Auditory Processing Disorder (APD)
Treatment and Support Solutions
If your child is diagnosed with hearing loss, treatment may include:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Assistance for Children with APD Diagnosis Typically Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written directions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Final Thoughts About Hearing Loss vs. APD
Understanding the distinction between hearing loss and auditory processing disorder is essential for getting your child the right help. If your child seems to have a hard time listening but their hearing test is normal, don’t stop there. The real issue may only be identified by more in-depth evaluations. Children with the appropriate diagnosis and personalized treatment approach can succeed academically, in their home environment, and in various other aspects of their lives.
