Central Auditory Processing Disorder (CAPD)

Explore what Central Auditory Processing Disorder (CAPD) is, its causes, and the telltale signs in children and adults. Understand why a CAPD test is recommended.

CAPD is believed to affect about 5% of school-aged children. Individuals with CAPD may have normal ear function but struggle with sound processing. For children, the symptoms will be more evident in noisy environments or when given several instructions at once. This can affect how the child performs in class.

What Are The Common Signs And Symptoms of CAPD?

Common signs and symptoms of CAPD include:

Difficulty following, understanding or remembering verbal instruction
Difficulty listening in a noisy situation
Easily distracted or inattentiveness
Difficulty remembering events or taking down notes
Difficulty understanding people talking quickly
Difficulty reading, spelling or comprehending
Difficulty multitasking (taking down notes while listening to the teacher)
Difficulty understanding sarcasm or jokes

What Are The Causes Of CAPD?

The exact causes of CAPD are still unknown. What’s known is that CAPD involves changes in how the brain processes sound, but the reasons are still being studied. It is also not clear whether the condition is congenital or develops post-birth. However, it is known that children with frequent ear infections may be more susceptible to developing CAPD.

What Is CAPD Assessment?

CAPD will not show up in a standard hearing test. A specific test for CAPD is performed to assess the auditory processing skills and hearing ability. This involves an extensive case history and a preliminary hearing test to rule out hearing loss.

During an auditory processing evaluation, the audiologist will perform a series of tests to determine if the individual is able to listen to speech in background noise, repeat a series of words or numbers, listen to words coming to both ears at the same time, and ignore words from one side and focus on the other side.

Each test assesses one or more auditory functions and is age–appropriate. The tests, lasting 2-3 hours, are only suitable for children aged seven and above. Diagnosing CAPD can be difficult because some of the signs may also overlap with attention, speech, language, and learning issues.

Many disorders present behavioural characteristics similar to CAPD that can cause the listener to perform poorly on behavioural central auditory function tests and/or exhibit similar functional listening difficulties (Ferre, 2014). A multi-disciplinary approach involving audiologists, speech pathologists, psychologists, doctors, and even teachers can help ensure that the individual receives a suitable diagnosis and care.

I started experiencing loss of hearing sometimes in 2010 (41 years old) owing to some medical issue. I was having difficulties hearing conservation especially in meeting. Thus, giving me the fear in attending meeting.

Initially I started with Phonak hearing aid. It helps amplified the sound and I could hear better then. Somehow, my hearing loss deteriorated further that in late 2012 (43 years old), there was profound loss of hearing on my right ear. Even digital hearing aid could not help. On my left ear there is still about 50% to 60% hearing with hearing aid. I was lost at this point of time. I was considering learning sign language. I went to see my ENT specialist and my audiologist Mr. Bala advised me to go for an CI as an alternative to my hearing loss.

I also thank God for Engineer and Scientist, giving them the knowledge to create such a complex and sophisticate device to help those with hearing loss like me. It will be all perfect if the cost is affordable too.

Titus was implanted when he was 18 months old. He is a happy, talkative 6.5 years old now. AB has been with him for 5 wonderful hearing years and we are looking forward to a bright future that lies ahead for him. AB’s Naída CI sound processors are reliable and the technology is constantly evolving and upgrading. When Titus was introduced to Naida Link CROS, his life was enriched. The wireless network established between his Naida CI sound processor and a Naida Link CROS transmitter allows him to hear from both ears. This changes Titus’s life and the way we interact with him. We are also very pleased with the prompt response and service provided to us. The staff in AB genuinely cares! We want to thank AB for making Titus’s hearing journey an enjoyable and a relatively stress free one!

I have been living with progressive hearing loss for more than three decades. Socially, I find myself fearful of communicating with people and at home, watching 'soundless' television programs is a norm.

An unforgettable experience. Trying on a pair of Resound GN hearing aid, I was energized and revitalized and overwhelmed with emotional tears of joy. The Resound GN is truly remarkable and uniquely equipped with three-friendly-user environmental modes that provide hearing comfort wherever we are.

In particular, I like to extend my utmost gratitude to Hearing Consultant. With her profound compassion and wisdom in guiding me, I am confident that I can forge a formidable partnership with the Listening Lab; So that I can rebuild a new chapter of a happy and value-creative life and simultaneously, leaving behind the painful memories of the past three decades.
