Central Auditory Processing Disorder, or CAPD, is a hearing disorder in which the trouble lies not with the ears, but with the brain. People with Central Auditory Processing Disorder have no difficulty hearing sounds – especially speech – but, their brains don’t interpret the sound inputs correctly. That’s why the disorder is sometimes summarized as an ear-brain coordination problem.
CAPD affects as many as 2% to 5% of school-age children, and as many as half of the children are diagnosed as having a learning disability. Children with Central Auditory Processing Disorder often fail to recognize subtle differences between the sounds of different words, even though the words are clear and loud enough for them to hear. This inability to understand words often becomes worse in noisy environments, but is not as present in quiet environments.
This can make Central Auditory Processing Disorder hard to detect. A child that can hear and intrepret speech well in a quiet environment will generally have no problems passing a hearing test administered in a quiet environment. But even though their audiogram results may appear normal, children with Central Auditory Processing Disorder often have difficulty locating where sounds are coming from, difficulty discerning the differences between two similar sounds, difficulty recognizing patterns of repetitive high and low sounds, and difficulty being able to hear more than one person speaking at the same time.
These symptoms may carry over into other areas of life, as the children struggle to cope with not being able to understand people speaking to them. For example, they may become easily distracted by sudden noises, have difficulty following directions, develop reading, spelling, and language difficulties, become disorganized and forgetful, or have trouble following conversations. When given standard hearing tests, these children appear to have normal hearing, so these symptoms are often confused with or mistaken for signs of other problems such as depression or Attention Deficit Hyperactivity Disorder (ADHD). This misdiagnosis is further complicated by the fact that a child may in fact have ADHD or some other learning disorder and also have CAPD.
Properly detecting and diagnosing CAPD as eary in a child’s life as possible is crucial to avoid developmental delays both social and academic. Early diagnosis is key to ensuring that the condition is resolved, which is why it is important, if you have noticed any of the above symptoms in your children, to have their hearing professionally tested.
